4. CLINICAL PARTICULARS 
 
4.1 Therapeutic indications 
 
Treatment of primary apnoea of premature newborns. 
 
4.2 Posology and method of administration 
 
Treatment with caffeine citrate should be initiated under the supervision of a physician experienced in 
neonatal intensive care. Treatment should be administered only in a neonatal intensive care unit in 
which adequate facilities are available for patient surveillance and monitoring. 
 
Posology 
 
The recommended dose regimen in previously untreated infants is a loading dose of 20 mg caffeine 
citrate per kg body weight administered by slow intravenous infusion over 30 minutes, using a syringe 
infusion pump or other metered infusion device. After an interval of 24 hours, maintenance doses of 
5 mg per kg body weight may be administered by slow intravenous infusion over 10 minutes every 
24 hours. Alternatively, maintenance doses of 5 mg per kg body weight may be administered by oral 
administration, such as through a nasogastric tube every 24 hours. 
The recommended loading dose and maintenance doses of caffeine citrate are provided in the 
following table which clarifies the relationship between injection volumes and administered doses 
expressed as caffeine citrate. 
The dose expressed as caffeine base is one-half the dose when expressed as caffeine citrate (10 mg 
caffeine citrate are equivalent to 5 mg caffeine base).

* Beginning 24 hours after the loading dose 
 
In preterm newborn infants with insufficient clinical response to the recommended loading dose, a 
second loading dose of 10-20 mg/kg maximum may be given after 24 hours. 
Higher maintenance doses of 10 mg/kg body weight could be considered in case of insufficient 
response, taking into account the potential for accumulation of caffeine due to the long half-life in 
preterm newborn infants and the progressively increasing capacity to metabolise caffeine in relation to 
post-menstrual age (see section 5.2). Where clinically indicated, caffeine plasma levels should be 
monitored. The diagnosis of apnoea of prematurity may need to be reconsidered if patients do not 
respond adequately to a second loading dose or maintenance dose of 10 mg/kg/day (see section 4.4). 
 
Dosage adjustments and monitoring 
Plasma concentrations of caffeine may need to be monitored periodically throughout treatment in 
cases of incomplete clinical response or signs of toxicity. 
Additionally, doses may need to be adjusted according to medical judgment following routine 
monitoring of caffeine plasma concentrations in at risk situations such as: 

- very premature infants (< 28 weeks gestational age and/or body weight <1000 g) particularly 
when receiving parenteral nutrition 

- infants with hepatic and renal impairment (see sections 4.4 and 5.2) 
- infants with seizure disorders 
- infants with known and clinically significant cardiac disease 
- infants receiving co-administration of medicinal products known to interfere with caffeine 

metabolism (see section 4.5) 
- infants whose mothers consume caffeine while providing breast milk for feeding. 

It is advisable to measure baseline caffeine levels in: 
- infants whose mothers may have ingested large quantities of caffeine prior to delivery (see 

section 4.4) 
- infants who have previously been treated with theophylline, which is metabolized to caffeine. 

 
Caffeine has a prolonged half-life in premature newborn infants and there is potential for accumulation 
which may necessitate monitoring infants treated for an extended period (see section 5.2). 
Blood samples for monitoring should be taken just before the next dose in the case of therapeutic 
failure and 2 to 4 hours after the previous dose when suspecting toxicity. 
 
Although a therapeutic plasma concentration range of caffeine has not been determined in the 
literature, caffeine levels in studies associated with clinical benefit ranged from 8 to 30 mg/l and no 
safety concerns have normally been raised with plasma levels below 50 mg/l. 
 
Duration of treatment 
The optimal duration of treatment has not been established. In a recent large multicentre study on 
preterm newborn infants a median treatment period of 37 days was reported. 
In clinical practice, treatment is usually continued until the infant has reached a post-menstrual age of 
37 weeks, by which time apnoea of prematurity usually resolves spontaneously. This limit may 
however be revised according to clinical judgment in individual cases depending on the response to 
treatment, the continuing presence of apnoeic episodes despite treatment, or other clinical 
considerations. It is recommended that caffeine citrate administration should be stopped when the 
patient has 5-7 days without a significant apnoeic attack. 
If the patient has recurrent apnoea, caffeine citrate administration can be restarted with either a 
maintenance dose or a half loading dose, depending upon the time interval from stopping caffeine 
citrate to recurrence of apnoea. 
Because of the slow elimination of caffeine in this patient population, there is no requirement for dose 
tapering on cessation of treatment. 
 
As there is a risk for recurrence of apnoeas after cessation of caffeine citrate treatment monitoring of 
the patient should be continued for approximately one week. 
 
Hepatic and renal impairment 



4 

There is limited experience in patients with renal and hepatic impairment. In a post authorisation 
safety study, the frequency of adverse reactions in a small number of very premature infants with 
renal/hepatic impairment appeared to be higher as compared to premature infants without organ 
impairment (see sections 4.4 and 4.8). 
In the presence of renal impairment, there is increased potential for accumulation. A reduced daily 
maintenance dose of caffeine citrate is required and the dose should be guided by plasma caffeine 
measurements. 
In very premature infants, clearance of caffeine does not depend on hepatic function. Hepatic caffeine 
metabolism develops progressively in the weeks following birth and for the older infants, hepatic 
disease may indicate a need for monitoring caffeine plasma levels and may require dose adjustments 
(see sections 4.4 and 5.2). 
 
Method of administration  
 
Caffeine citrate can be administered by intravenous infusion and by the oral route. The medicinal 
product must not be administered by intramuscular, subcutaneous, intrathecal or intraperitoneal 
injection. 
 
When given intravenously, caffeine citrate should be administered by controlled intravenous infusion, 
using a syringe infusion pump or other metered infusion device only. Caffeine citrate can be either 
used without dilution or diluted in sterile solutions for infusion such as glucose 50 mg/ml (5%), or 
sodium chloride 9 mg/ml (0.9%) or calcium gluconate 100 mg/ml (10%) immediately after withdrawal 
from the ampoule (see section 6.6). 
 
4.3 Contraindications 
 
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. 
 
4.4 Special warnings and precautions for use 
 
Apnoea 
 
Apnoea of prematurity is a diagnosis of exclusion. Other causes of apnoea (e.g., central nervous 
system disorders, primary lung disease, anaemia, sepsis, metabolic disturbances, cardiovascular 
abnormalities, or obstructive apnoea) should be ruled out or properly treated prior to initiation of 
treatment with caffeine citrate. Failure to respond to caffeine treatment (confirmed if necessary by 
measurement of plasma levels) could be an indication of another cause of apnoea. 
 
Caffeine consumption 
 
In newborn infants born to mothers who consumed large quantities of caffeine prior to delivery, 
baseline plasma caffeine concentrations should be measured prior to initiation of treatment with 
caffeine citrate, since caffeine readily crosses the placenta into the foetal circulation (see sections 4.2 
and 5.2). 
 
Breast-feeding mothers of newborn infants treated with caffeine citrate should not ingest caffeine- 
containing foods and beverages or medicinal products containing caffeine (see section 4.6), since 
caffeine is excreted into breast milk (see section 5.2). 
 
Theophylline 
 
In newborns previously treated with theophylline, baseline plasma caffeine concentrations should be 
measured prior to initiation of treatment with caffeine citrate because preterm infants metabolise 
theophylline to caffeine. 
 
Seizures 
 



5 

Caffeine is a central nervous system stimulant and seizures have been reported in cases of caffeine 
overdose. Extreme caution must be exercised if caffeine citrate is used in newborns with seizure 
disorders. 
 
Cardiovascular reactions 
 
Caffeine has been shown to increase heart rate, left ventricular output, and stroke volume in published 
studies. Therefore, caffeine citrate should be used with caution in newborns with known 
cardiovascular disease. There is evidence that caffeine causes tachyarrhythmias in susceptible 
individuals. In newborns this is usually a simple sinus tachycardia. If there have been any unusual 
rhythm disturbances on a cardiotocograph (CTG) trace before the baby is born, caffeine citrate should 
be administered with caution. 
 
Renal and hepatic impairment 
 
Caffeine citrate should be administered with caution in preterm newborn infants with impaired renal or 
hepatic function. In a post-authorisation safety study, the frequency of adverse reactions in a small 
number of very premature infants with renal/hepatic impairment appeared to be higher as compared to 
premature infants without organ impairment (see sections 4.2, 4.8 and 5.2). Doses should be adjusted 
by monitoring of caffeine plasma concentrations to avoid toxicity in this population. 
 
Necrotising enterocolitis 
 
Necrotising enterocolitis is a common cause of morbidity and mortality in premature newborn infants. 
There are reports of a possible association between the use of methylxanthines and development of 
necrotising enterocolitis. However, a causal relationship between caffeine or other methylxanthine use 
and necrotising enterocolitis has not been established. As for all preterm infants, those treated with 
caffeine citrate should be carefully monitored for the development of necrotising enterocolitis (see 
section 4.8). 
 
Caffeine citrate should be used with caution in infants suffering gastro-oesophageal reflux, as the 
treatment may exacerbate this condition. 
 
Caffeine citrate causes a generalised increase in metabolism, which may result in higher energy and 
nutrition requirements during therapy. 
 
The diuresis and electrolyte loss induced by caffeine citrate may necessitate correction of fluid and 
electrolyte disturbances. 
 
4.5 Interaction with other medicinal products and other forms of interaction 
 
Inter-conversion between caffeine and theophylline occurs in preterm newborn infants. These active 
substances should not be used concurrently. 
 
Cytochrome P450 1A2 (CYP1A2) is the major enzyme involved in the metabolism of caffeine in 
humans. Therefore, caffeine has the potential to interact with active substances that are substrates for 
CYP1A2, inhibit CYP1A2, or induce CYP1A2. However, caffeine metabolism in preterm newborn 
infants is limited due to their immature hepatic enzyme systems. 
 
Although few data exist on interactions of caffeine with other active substances in preterm newborn 
infants, lower doses of caffeine citrate may be needed following co-administration of active substances 
which are reported to decrease caffeine elimination in adults (e.g., cimetidine and ketoconazole) and 
higher caffeine citrate doses may be needed following co-administration of active substances that 
increase caffeine elimination (e.g., phenobarbital and phenytoin). Where doubt exists about possible 
interactions, plasma caffeine concentrations should be measured. 
As bacterial overgrowth in the gut is associated with the development of necrotising enterocolitis, co- 
administration of caffeine citrate with medicinal products that suppress gastric acid secretion 



6 

(antihistamine H2 receptor blockers or proton-pump inhibitors) may in theory increase the risk of 
necrotising enterocolitis (see section 4.4 and 4.8). 
Concurrent use of caffeine and doxapram might potentiate their stimulatory effects on the cardio- 
respiratory and central nervous system. If concurrent use is indicated, cardiac rhythm and blood 
pressure must be carefully monitored. 
 
4.6 Fertility, pregnancy and lactation 
 
Pregnancy 
 
Caffeine in animal studies, at high doses, was shown to be embryotoxic and teratogenic. These effects 
are not relevant with regard to short term administration in the preterm infant population (see section 
5.3). 
 
Breast-feeding 
 
Caffeine is excreted into breast milk and readily crosses the placenta into the foetal circulation (see 
section 5.2). 
Breast-feeding mothers of newborn infants treated with caffeine citrate should not ingest caffeine- 
containing foods, beverages or medicinal products containing caffeine. 
In newborn infants born to mothers who consumed large quantities of caffeine prior to delivery, 
baseline plasma caffeine concentrations should be measured prior to initiation of treatment with 
caffeine citrate (see section 4.4). 
 
Fertility 
 
Effects on reproductive performance observed in animals are not relevant to its indication in the 
preterm newborn infants (see section 5.3). 
 
4.7 Effects on ability to drive and use machines 
 
Not relevant. 
 
4.8 Undesirable effects 
 
Summary of the safety profile 
 
The known pharmacology and toxicology of caffeine and other methylxanthines predict the likely 
adverse reactions to caffeine citrate. Effects described include central nervous system (CNS) stimulation 
such as convulsion, irritability, restlessness and jitteriness, cardiac effects such as tachycardia, 
arrhythmia, hypertension and increased stroke volume, metabolism and nutrition disorders such as 
hyperglycaemia. These effects are dose related and may necessitate measurement of plasma levels and 
dose reduction.

Description of selected adverse reactions 
 
Necrotising enterocolitis is a common cause of morbidity and mortality in premature newborn infants. 
There are reports of a possible association between the use of methylxanthines and development of 
necrotising enterocolitis. However, a causal relationship between caffeine or other methylxanthine use 
and necrotising enterocolitis has not been established. 
In a double-blind placebo-controlled study of caffeine citrate in 85 preterm infants (see section 5.1), 
necrotising enterocolitis was diagnosed in the blinded phase of the study in two infants on active 
treatment and one on placebo, and in three infants on caffeine during the open-label phase of the study. 
Three of the infants who developed necrotising enterocolitis during the study died. A large multicentre 
study (n=2006) investigating long-term outcome of premature infants treated with caffeine citrate (see 
section 5.1) did not show an increased frequency of necrotising enterocolitis in the caffeine group when 
compared to placebo. As for all preterm infants, those treated with caffeine citrate should be carefully 
monitored for the development of necrotising enterocolitis (see section 4.4). 
Brain injury, convulsion and deafness were observed but they were more frequent in the placebo group. 
 
Caffeine may suppress erythropoietin synthesis and hence reduce haemoglobin concentration with 
prolonged treatment. 
Transient falls in thyroxine (T4) have been recorded in infants at the start of therapy but these are not 
sustained with maintained therapy. 
Available evidence does not indicate any adverse long-term reactions of neonatal caffeine therapy as 
regards neurodevelopmental outcome, failure to thrive or on the cardiovascular, gastrointestinal or 
endocrine systems. Caffeine does not appear to aggravate cerebral hypoxia or to exacerbate any resulting 
damage, although the possibility cannot be ruled out. 
 
Other special populations 
 



8 

In a post-authorisation safety study on 506 preterm infants treated with caffeine citrate, safety data have 
been collected in 31 very premature infants with renal/hepatic impairment. Adverse reactions appeared 
to be more frequent in this subgroup with organ impairment than in other observed infants without organ 
impairment. Cardiac disorders (tachycardia, including one single case of arrhythmia) were mostly 
reported. 
 
Reporting of suspected adverse reactions 
 
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It 
allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare 
professionals are asked to report any suspected adverse reactions via the national reporting system 
listed in Appendix V. 
 
4.9 Overdose 
 
Following overdose, published plasma caffeine levels have ranged from approximately 50 mg/l to 
350 mg/l. 
 
Symptoms 
 
Signs and symptoms reported in the literature after caffeine overdose in preterm infants include 
hyperglycaemia, hypokalaemia, fine tremor of the extremities, restlessness, hypertonia, opisthotonus, 
tonic clonic movements, seizures, tachypnoea, tachycardia, vomiting, gastric irritation, gastro-
intestinal haemorrhage, pyrexia, jitteriness, increased blood urea and increased white blood cell count, 
non-purposeful jaw and lip movements. One case of caffeine overdose complicated by development of 
intraventricular haemorrhage and long-term neurological sequelae has been reported. No deaths 
associated with caffeine overdose have been reported in preterm infants. 
 
Management 
 
Treatment of caffeine overdose is primarily symptomatic and supportive. Plasma potassium and 
glucose concentrations should be monitored and hypokalaemia and hyperglycaemia corrected. Plasma 
caffeine concentrations have been shown to decrease after exchange transfusion. Convulsions may be 
treated with intravenous administration of anticonvulsants (diazepam or a barbiturate such as 
pentobarbital sodium or phenobarbital). 
 
 

5. PHARMACOLOGICAL PROPERTIES 
 
5.1  Pharmacodynamic properties 
 
Pharmacotherapeutic group: Psychoanaleptics, xanthine derivatives, ATC code: N06BC01 
 
Mechanism of action 
 
Caffeine is structurally related to the methylxanthines theophylline and theobromine. 
Most of its effects have been attributed to antagonism of adenosine receptors, both A1 and A2A 
subtypes, demonstrated in receptor binding assays and observed at concentrations approximating those 
achieved therapeutically in this indication. 
 
Pharmacodynamic effects 
 
Caffeine’s main action is as a CNS stimulant. This is the basis of caffeine’s effect in apnoea of 
prematurity, for which several mechanisms have been proposed for its actions including: (1) 
respiratory centre stimulation, (2) increased minute ventilation, (3) decreased threshold to

9 

hypercapnia, (4) increased response to hypercapnia, (5) increased skeletal muscle tone, (6) decreased 
diaphragmatic fatigue, (7) increased metabolic rate, and (8) increased oxygen consumption. 
 
Clinical efficacy and safety 
 
The clinical efficacy of caffeine citrate was assessed in a multicentre, randomised, double-blind study 
that compared caffeine citrate to placebo in 85 preterm infants (gestational age 28 to <33 weeks) with 
apnoea of prematurity. Infants received 20 mg/kg caffeine citrate loading dose intravenously. A 
maintenance daily dose of 5 mg/kg caffeine citrate was then administered either intravenously or 
orally (through a feeding tube) for up to 10-12 days. The protocol allowed infants to be “rescued” with 
open-label caffeine citrate treatment if their apnoea remained uncontrolled. In that case, infants 
received a second loading dose of 20 mg/kg caffeine citrate after treatment day 1 and before treatment 
day 8. 
There were more days without any apnoea under caffeine citrate treatment (3.0 days, versus 1.2 days 
for placebo; p=0.005); also, there was a higher percentage of patients with no apnoeas for ≥ 8 days 
(caffeine 22% versus placebo 0%). 
A recent large placebo-controlled multicentre study (n=2006) investigated short-term and long-term 
(18-21 months) outcomes of premature infants treated with caffeine citrate. Infants randomised to 
caffeine citrate received an intravenous loading dose of 20 mg/kg, followed by a daily maintenance 
dose of 5 mg/kg. If apnoeas persisted, the daily maintenance dose could be increased to a maximum of 
10 mg/kg of caffeine citrate. The maintenance doses were adjusted weekly for changes in body weight 
and could be given orally once an infant tolerated full enteral feedings. Caffeine therapy reduced the 
rate of bronchopulmonary dysplasia [odds ratio (95% CI) 0.63 (0.52 to 0.76)] and improved the rate of 
survival without neurodevelopmental disability [odds ratio (95 %CI) 0.77 (0.64 to 0.93)]. 
The size and direction of caffeine effect on death and disability differed depending on the degree of 
respiratory support infants needed at randomisation, indicating more benefit for the supported infants 
[odds ratio (95%CI) for death and disability, see table below]. 
 

Death or disability according to subgroup of respiratory support at entry to study 
Subgroups Odds ratio (95% CI) 
No support 1.32 (0.81 to 2.14) 
Non invasive support 0.73 (0.52 to 1.03) 
Endotracheal tube 0.73 (0.57 to 0.94) 

 
5.2 Pharmacokinetic properties 
 
Caffeine citrate readily dissociates in aqueous solution. The citrate moiety is rapidly metabolized on 
infusion or ingestion. 
 
Absorption 
 
The onset of action of caffeine from caffeine citrate is within minutes of commencement of infusion. 
After oral administration of 10 mg caffeine base/kg body weight to preterm newborn infants, the peak 
plasma caffeine concentration (Cmax) ranged from 6 to 10 mg/l and the mean time to reach peak 
concentration (tmax) ranged from 30 min to 2 h. The extent of absorption is not affected by formula 
feeding but tmax may be prolonged. 
 
Distribution 
 
Caffeine is rapidly distributed into the brain following caffeine citrate administration. Caffeine 
concentrations in the cerebrospinal fluid of preterm newborn infants approximate to their plasma 
levels. The mean volume of distribution (Vd) of caffeine in infants (0.8-0.9 l/kg) is slightly higher than 
that in adults (0.6 l/kg). Plasma protein binding data are not available for newborn infants or infants. In 
adults, the mean plasma protein binding in vitro is reported to be approximately 36%. 
 
Caffeine readily crosses the placenta into the foetal circulation and is excreted into breast milk. 
 



10 

Biotransformation 
 
Caffeine metabolism in preterm newborn infants is very limited due to their immature hepatic enzyme 
systems and most of the active substance is eliminated in urine. Hepatic cytochrome P450 1A2 
(CYP1A2) is involved in caffeine biotransformation in older individuals. 
Inter-conversion between caffeine and theophylline has been reported in preterm newborn infants; 
caffeine levels are approximately 25% of theophylline levels after theophylline administration and 
approximately 3-8% of caffeine administered would be expected to convert to theophylline. 
 
Elimination 
 
In young infants, the elimination of caffeine is much slower than that in adults due to immature 
hepatic and/or renal function. In newborn infants, caffeine clearance is almost entirely by renal 
excretion. Mean half-life (t1/2) and fraction excreted unchanged in urine (Ae) of caffeine in infants are 
inversely related to gestational / postmenstrual age. In newborn infants, the t1/2 is approximately 3-
4 days and the Ae is approximately 86% (within 6 days). By 9 months of age, the metabolism of 
caffeine approximates to that seen in adults (t1/2 = 5 hours and Ae = 1%). 
Studies examining the pharmacokinetics of caffeine in newborn infants with hepatic or renal 
insufficiency have not been conducted. 
In the presence of significant renal impairment, considering the increased potential for accumulation, a 
reduced daily maintenance dose of caffeine is required and the doses should be guided by blood 
caffeine measurements. In premature infants with cholestatic hepatitis a prolonged caffeine 
elimination half-life with an increase of plasma levels above the normal limit of variation has been 
found suggesting a particular caution in the dosage of these patients (see sections 4.2 and 4.4). 
 
5.3 Preclinical safety data 
 
Non-clinical data revealed no major hazard for humans based on studies of repeated dose toxicity of 
caffeine. However, at high doses convulsions in rodents were induced. At therapeutic doses some 
behavioural changes in newborn rats were induced, most likely as a consequence of increased 
adenosine receptor expression that persisted into adulthood. Caffeine was shown to be devoid of 
mutagenic and oncogenic risk. Teratogenic potential and effects on reproductive performance 
observed in animals are not relevant to its indication in the preterm infant population.

Package leaflet: Information for the user 
 

Gencebok 10 mg/ml solution for infusion  
caffeine citrate 

 
Read all of this leaflet carefully before treatment with this medicine because it contains 
important information for your newborn 
- Keep this leaflet. You may need to read it again.  
- If you have any further questions, please ask your baby’s doctor. 
- If your newborn gets any side effects, talk to your baby’s doctor. This includes any possible 

side effects not listed in this leaflet. See section 4. 
 
What is in this leaflet 
 
1. What Gencebok is and what it is used for  
2. What you need to know before your baby is given Gencebok 
3. How to use Gencebok 
4. Possible side effects  
5. How to store Gencebok 
6. Contents of the pack and other information 
 
 
1. What Gencebok is and what it is used for 
 
Gencebok contains the active substance caffeine citrate, which is a stimulant of the central nervous 
system, belonging to a group of medicines called methylxanthines. 
 
Gencebok is used in the treatment of interrupted breathing in premature babies (primary apnoea of 
premature newborns). 
These short periods when premature babies stop breathing are due to the baby’s breathing centres not 
being fully developed. 
This medicine has been shown to reduce the number of episodes of interrupted breathing in premature 
newborns. 
 
 
2. What you need to know before your baby is given Gencebok 
 
Do not use Gencebok 
- If your newborn is allergic to caffeine citrate or any of the other ingredients of this medicine 

(listed in section 6). 
 
Warnings and precautions  
Talk to your baby’s doctor before your newborn is given Gencebok. 
Prior to starting treatment for apnoea of prematurity with Gencebok other causes of apnoea should 
have been excluded or properly treated by your baby’s doctor. 
 
Gencebok should be used with caution. Please inform your baby’s doctor: 
 
- If your newborn suffers from seizures 
- If your newborn suffers from any heart disease 
- If your newborn has kidney or liver problems 
- If your newborn has frequent regurgitation 
- If your newborn produces more urine than usual 
- If your newborn has a reduced weight gain or food intake 
- If you (the mother) consumed caffeine prior to delivery 
 
Other medicines and Gencebok 



23 

Tell your baby’s doctor if your newborn is taking, have recently taken or might take any other 
medicines. 
Please inform your baby’s doctor if your newborn has been previously treated with theophylline.  Do 
not use the following medicines during the treatment with Gencebok without talking to your baby’s 
doctor. The doctor may need to adjust the dose or change one of the medicines to something else: 
- theophylline (used to treat breathing difficulties) 
- doxapram (used to treat breathing difficulties) 
- cimetidine (used to treat gastric disease) 
- ketoconazole (used to treat fungine infections) 
- phenobarbital (used to treat epilepsy) 
- phenytoin (used to treat epilepsy) 
 
This medicine may increase the risk for serious intestinal disease with bloody stools (necrotising 
enterocolitis) when administered with medicines used to treat gastric disease (such as antihistamine 
H2 receptor blockers or proton-pump inhibitors that reduces gastric acid secretion). 
 
Pregnancy and breast-feeding  
If you (the mother) are breast-feeding while your infant is treated with Gencebok, you should not 
drink coffee or take any other high caffeine product as caffeine passes into breast milk. 
 
Gencebok contains sodium 
This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e. is essentially ‘sodium-
free’. 
 
3. How to use Gencebok 
 
Gencebok should only be used in a neonatal intensive care unit in which adequate facilities are 
available for patient surveillance and monitoring. Treatment should be initiated under 
supervision of a physician experienced in neonatal intensive care. 
 
Dose 
Your baby’s doctor will prescribe the right amount of Gencebok based on your baby’s weight. The 
starting dose is 20 mg per kg body weight (equivalent to 2 ml per kg body weight). 
The maintenance dose is 5 mg per kg body weight (equivalent to 0.5 ml per kg body weight) every 
24 hours. 
 
Route and method of administration 
Gencebok will be infused by controlled intravenous infusion, using a syringe infusion pump or other 
metered infusion device. This method is also known as “a drip”. 
Some of the doses (maintenance doses) may be given by mouth. 
It may be needed that your baby’s doctor decides to check the levels of caffeine in a blood test 
periodically throughout treatment to avoid toxicity. 
 
Duration of treatment 
Your baby’s doctor will decide exactly how long your newborn must continue therapy with Gencebok. 
If your baby has 5 to 7 days without apnoea attacks, the doctor will stop the treatment. 
 
If your newborn receives more Gencebok than he/she should 
Your newborn may experience fever, rapid breathing (tachypnoea), jitteriness, muscular tremor 
vomiting, high blood levels of sugar (hyperglycemia), low blood levels of potassium (hypokalaemia), 
high blood levels of certain chemicals (urea), elevated number of certain cells (leukocyte) in blood and 
seizures if he/she receives more caffeine citrate than he/she should. 
In the event of this happening treatment with Gencebok should be stopped immediately and your 
baby’s doctor should treat the overdose. 
 
If you have any further questions on the use of this medicinal product, ask your baby’s doctor.

ANNEX I



SUMMARY OF PRODUCT CHARACTERISTICS




1.	NAME OF THE MEDICINAL PRODUCT



Gencebok 10 mg/ml solution for infusion





2.	QUALITATIVE AND QUANTITATIVE COMPOSITION



Each ml contains 10 mg caffeine citrate (equivalent to 5 mg caffeine).

Each 1 ml ampoule contains 10 mg caffeine citrate (equivalent to 5 mg caffeine).



For the full list of excipients, see section 6.1.





3.	PHARMACEUTICAL FORM



Solution for infusion.

Clear, colourless, aqueous solution, with a pH of 4.8 and an osmolality of 65 to 95 mOsm/kg.





4.	CLINICAL PARTICULARS



4.1	Therapeutic indications



Treatment of primary apnoea of premature newborns.



4.2	Posology and method of administration



Treatment with caffeine citrate should be initiated under the supervision of a physician experienced in neonatal intensive care. Treatment should be administered only in a neonatal intensive care unit in which adequate facilities are available for patient surveillance and monitoring.



Posology



The recommended dose regimen in previously untreated infants is a loading dose of 20 mg caffeine citrate per kg body weight administered by slow intravenous infusion over 30 minutes, using a syringe infusion pump or other metered infusion device. After an interval of 24 hours, maintenance doses of 5 mg per kg body weight may be administered by slow intravenous infusion over 10 minutes every 24 hours. Alternatively, maintenance doses of 5 mg per kg body weight may be administered by oral administration, such as through a nasogastric tube every 24 hours.

The recommended loading dose and maintenance doses of caffeine citrate are provided in the following table which clarifies the relationship between injection volumes and administered doses expressed as caffeine citrate.

The dose expressed as caffeine base is one-half the dose when expressed as caffeine citrate (10 mg caffeine citrate are equivalent to 5 mg caffeine base).

		Frequency



		Loading dose

		20 mg/kg body weight

		Intravenous infusion (over 30 minutes)

		Once



		Maintenance dose*

		0.5 ml/kg body weight

		5 mg/kg body weight

		Intravenous infusion (over 10 minutes) or by

oral administration

		Every 24 hours*





* Beginning 24 hours after the loading dose



In preterm newborn infants with insufficient clinical response to the recommended loading dose, a second loading dose of 10-20 mg/kg maximum may be given after 24 hours.

Higher maintenance doses of 10 mg/kg body weight could be considered in case of insufficient response, taking into account the potential for accumulation of caffeine due to the long half-life in preterm newborn infants and the progressively increasing capacity to metabolise caffeine in relation to post-menstrual age (see section 5.2). Where clinically indicated, caffeine plasma levels should be monitored. The diagnosis of apnoea of prematurity may need to be reconsidered if patients do not respond adequately to a second loading dose or maintenance dose of 10 mg/kg/day (see section 4.4).



Dosage adjustments and monitoring

Plasma concentrations of caffeine may need to be monitored periodically throughout treatment in cases of incomplete clinical response or signs of toxicity.

Additionally, doses may need to be adjusted according to medical judgment following routine monitoring of caffeine plasma concentrations in at risk situations such as:

· very premature infants (< 28 weeks gestational age and/or body weight <1000 g) particularly when receiving parenteral nutrition

· infants with hepatic and renal impairment (see sections 4.4 and 5.2)

· infants with seizure disorders

· infants with known and clinically significant cardiac disease

· infants receiving co-administration of medicinal products known to interfere with caffeine metabolism (see section 4.5)

· infants whose mothers consume caffeine while providing breast milk for feeding.

It is advisable to measure baseline caffeine levels in:

· infants whose mothers may have ingested large quantities of caffeine prior to delivery (see section 4.4)

· infants who have previously been treated with theophylline, which is metabolized to caffeine.



Caffeine has a prolonged half-life in premature newborn infants and there is potential for accumulation which may necessitate monitoring infants treated for an extended period (see section 5.2).

Blood samples for monitoring should be taken just before the next dose in the case of therapeutic failure and 2 to 4 hours after the previous dose when suspecting toxicity.



Although a therapeutic plasma concentration range of caffeine has not been determined in the literature, caffeine levels in studies associated with clinical benefit ranged from 8 to 30 mg/l and no safety concerns have normally been raised with plasma levels below 50 mg/l.



Duration of treatment

The optimal duration of treatment has not been established. In a recent large multicentre study on preterm newborn infants a median treatment period of 37 days was reported.

In clinical practice, treatment is usually continued until the infant has reached a post-menstrual age of 37 weeks, by which time apnoea of prematurity usually resolves spontaneously. This limit may however be revised according to clinical judgment in individual cases depending on the response to treatment, the continuing presence of apnoeic episodes despite treatment, or other clinical considerations. It is recommended that caffeine citrate administration should be stopped when the patient has 5-7 days without a significant apnoeic attack.

If the patient has recurrent apnoea, caffeine citrate administration can be restarted with either a maintenance dose or a half loading dose, depending upon the time interval from stopping caffeine citrate to recurrence of apnoea.

Because of the slow elimination of caffeine in this patient population, there is no requirement for dose tapering on cessation of treatment.



As there is a risk for recurrence of apnoeas after cessation of caffeine citrate treatment monitoring of the patient should be continued for approximately one week.



Hepatic and renal impairment

There is limited experience in patients with renal and hepatic impairment. In a post authorisation safety study, the frequency of adverse reactions in a small number of very premature infants with renal/hepatic impairment appeared to be higher as compared to premature infants without organ impairment (see sections 4.4 and 4.8).

In the presence of renal impairment, there is increased potential for accumulation. A reduced daily maintenance dose of caffeine citrate is required and the dose should be guided by plasma caffeine measurements.

In very premature infants, clearance of caffeine does not depend on hepatic function. Hepatic caffeine metabolism develops progressively in the weeks following birth and for the older infants, hepatic disease may indicate a need for monitoring caffeine plasma levels and may require dose adjustments (see sections 4.4 and 5.2).



Method of administration 



Caffeine citrate can be administered by intravenous infusion and by the oral route. The medicinal product must not be administered by intramuscular, subcutaneous, intrathecal or intraperitoneal injection.



When given intravenously, caffeine citrate should be administered by controlled intravenous infusion, using a syringe infusion pump or other metered infusion device only. Caffeine citrate can be either used without dilution or diluted in sterile solutions for infusion such as glucose 50 mg/ml (5%), or sodium chloride 9 mg/ml (0.9%) or calcium gluconate 100 mg/ml (10%) immediately after withdrawal from the ampoule (see section 6.6).



4.3	Contraindications



Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.



4.4	Special warnings and precautions for use



Apnoea



Apnoea of prematurity is a diagnosis of exclusion. Other causes of apnoea (e.g., central nervous system disorders, primary lung disease, anaemia, sepsis, metabolic disturbances, cardiovascular abnormalities, or obstructive apnoea) should be ruled out or properly treated prior to initiation of treatment with caffeine citrate. Failure to respond to caffeine treatment (confirmed if necessary by measurement of plasma levels) could be an indication of another cause of apnoea.



Caffeine consumption



In newborn infants born to mothers who consumed large quantities of caffeine prior to delivery, baseline plasma caffeine concentrations should be measured prior to initiation of treatment with caffeine citrate, since caffeine readily crosses the placenta into the foetal circulation (see sections 4.2 and 5.2).



Breast-feeding mothers of newborn infants treated with caffeine citrate should not ingest caffeine- containing foods and beverages or medicinal products containing caffeine (see section 4.6), since caffeine is excreted into breast milk (see section 5.2).



Theophylline



In newborns previously treated with theophylline, baseline plasma caffeine concentrations should be measured prior to initiation of treatment with caffeine citrate because preterm infants metabolise theophylline to caffeine.



Seizures



Caffeine is a central nervous system stimulant and seizures have been reported in cases of caffeine overdose. Extreme caution must be exercised if caffeine citrate is used in newborns with seizure disorders.



Cardiovascular reactions



Caffeine has been shown to increase heart rate, left ventricular output, and stroke volume in published studies. Therefore, caffeine citrate should be used with caution in newborns with known cardiovascular disease. There is evidence that caffeine causes tachyarrhythmias in susceptible individuals. In newborns this is usually a simple sinus tachycardia. If there have been any unusual rhythm disturbances on a cardiotocograph (CTG) trace before the baby is born, caffeine citrate should be administered with caution.



Renal and hepatic impairment



Caffeine citrate should be administered with caution in preterm newborn infants with impaired renal or hepatic function. In a post-authorisation safety study, the frequency of adverse reactions in a small number of very premature infants with renal/hepatic impairment appeared to be higher as compared to premature infants without organ impairment (see sections 4.2, 4.8 and 5.2). Doses should be adjusted by monitoring of caffeine plasma concentrations to avoid toxicity in this population.



Necrotising enterocolitis



Necrotising enterocolitis is a common cause of morbidity and mortality in premature newborn infants. There are reports of a possible association between the use of methylxanthines and development of necrotising enterocolitis. However, a causal relationship between caffeine or other methylxanthine use and necrotising enterocolitis has not been established. As for all preterm infants, those treated with caffeine citrate should be carefully monitored for the development of necrotising enterocolitis (see section 4.8).



Caffeine citrate should be used with caution in infants suffering gastro-oesophageal reflux, as the treatment may exacerbate this condition.



Caffeine citrate causes a generalised increase in metabolism, which may result in higher energy and nutrition requirements during therapy.



The diuresis and electrolyte loss induced by caffeine citrate may necessitate correction of fluid and electrolyte disturbances.



4.5	Interaction with other medicinal products and other forms of interaction



Inter-conversion between caffeine and theophylline occurs in preterm newborn infants. These active substances should not be used concurrently.



Cytochrome P450 1A2 (CYP1A2) is the major enzyme involved in the metabolism of caffeine in humans. Therefore, caffeine has the potential to interact with active substances that are substrates for CYP1A2, inhibit CYP1A2, or induce CYP1A2. However, caffeine metabolism in preterm newborn infants is limited due to their immature hepatic enzyme systems.



Although few data exist on interactions of caffeine with other active substances in preterm newborn infants, lower doses of caffeine citrate may be needed following co-administration of active substances which are reported to decrease caffeine elimination in adults (e.g., cimetidine and ketoconazole) and higher caffeine citrate doses may be needed following co-administration of active substances that increase caffeine elimination (e.g., phenobarbital and phenytoin). Where doubt exists about possible interactions, plasma caffeine concentrations should be measured.

As bacterial overgrowth in the gut is associated with the development of necrotising enterocolitis, co- administration of caffeine citrate with medicinal products that suppress gastric acid secretion (antihistamine H2 receptor blockers or proton-pump inhibitors) may in theory increase the risk of necrotising enterocolitis (see section 4.4 and 4.8).

Concurrent use of caffeine and doxapram might potentiate their stimulatory effects on the cardio- respiratory and central nervous system. If concurrent use is indicated, cardiac rhythm and blood pressure must be carefully monitored.



4.6	Fertility, pregnancy and lactation



Pregnancy



Caffeine in animal studies, at high doses, was shown to be embryotoxic and teratogenic. These effects are not relevant with regard to short term administration in the preterm infant population (see section 5.3).



Breast-feeding



Caffeine is excreted into breast milk and readily crosses the placenta into the foetal circulation (see section 5.2).

Breast-feeding mothers of newborn infants treated with caffeine citrate should not ingest caffeine- containing foods, beverages or medicinal products containing caffeine.

In newborn infants born to mothers who consumed large quantities of caffeine prior to delivery, baseline plasma caffeine concentrations should be measured prior to initiation of treatment with caffeine citrate (see section 4.4).



Fertility



Effects on reproductive performance observed in animals are not relevant to its indication in the preterm newborn infants (see section 5.3).



4.7	Effects on ability to drive and use machines



Not relevant.



4.8	Undesirable effects



Summary of the safety profile



The known pharmacology and toxicology of caffeine and other methylxanthines predict the likely adverse reactions to caffeine citrate. Effects described include central nervous system (CNS) stimulation such as convulsion, irritability, restlessness and jitteriness, cardiac effects such as tachycardia, arrhythmia, hypertension and increased stroke volume, metabolism and nutrition disorders such as hyperglycaemia. These effects are dose related and may necessitate measurement of plasma levels and dose reduction.

Description of selected adverse reactions



Necrotising enterocolitis is a common cause of morbidity and mortality in premature newborn infants. There are reports of a possible association between the use of methylxanthines and development of necrotising enterocolitis. However, a causal relationship between caffeine or other methylxanthine use and necrotising enterocolitis has not been established.

In a double-blind placebo-controlled study of caffeine citrate in 85 preterm infants (see section 5.1), necrotising enterocolitis was diagnosed in the blinded phase of the study in two infants on active treatment and one on placebo, and in three infants on caffeine during the open-label phase of the study. Three of the infants who developed necrotising enterocolitis during the study died. A large multicentre study (n=2006) investigating long-term outcome of premature infants treated with caffeine citrate (see section 5.1) did not show an increased frequency of necrotising enterocolitis in the caffeine group when compared to placebo. As for all preterm infants, those treated with caffeine citrate should be carefully monitored for the development of necrotising enterocolitis (see section 4.4).

Brain injury, convulsion and deafness were observed but they were more frequent in the placebo group.



Caffeine may suppress erythropoietin synthesis and hence reduce haemoglobin concentration with prolonged treatment.

Transient falls in thyroxine (T4) have been recorded in infants at the start of therapy but these are not sustained with maintained therapy.

Available evidence does not indicate any adverse long-term reactions of neonatal caffeine therapy as regards neurodevelopmental outcome, failure to thrive or on the cardiovascular, gastrointestinal or endocrine systems. Caffeine does not appear to aggravate cerebral hypoxia or to exacerbate any resulting damage, although the possibility cannot be ruled out.



Other special populations



In a post-authorisation safety study on 506 preterm infants treated with caffeine citrate, safety data have been collected in 31 very premature infants with renal/hepatic impairment. Adverse reactions appeared to be more frequent in this subgroup with organ impairment than in other observed infants without organ impairment. Cardiac disorders (tachycardia, including one single case of arrhythmia) were mostly reported.



Reporting of suspected adverse reactions



Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V.



4.9	Overdose



Following overdose, published plasma caffeine levels have ranged from approximately 50 mg/l to 350 mg/l.



Symptoms



Signs and symptoms reported in the literature after caffeine overdose in preterm infants include hyperglycaemia, hypokalaemia, fine tremor of the extremities, restlessness, hypertonia, opisthotonus, tonic clonic movements, seizures, tachypnoea, tachycardia, vomiting, gastric irritation, gastro-intestinal haemorrhage, pyrexia, jitteriness, increased blood urea and increased white blood cell count, non-purposeful jaw and lip movements. One case of caffeine overdose complicated by development of intraventricular haemorrhage and long-term neurological sequelae has been reported. No deaths associated with caffeine overdose have been reported in preterm infants.



Management



Treatment of caffeine overdose is primarily symptomatic and supportive. Plasma potassium and glucose concentrations should be monitored and hypokalaemia and hyperglycaemia corrected. Plasma caffeine concentrations have been shown to decrease after exchange transfusion. Convulsions may be treated with intravenous administration of anticonvulsants (diazepam or a barbiturate such as pentobarbital sodium or phenobarbital).





5.	PHARMACOLOGICAL PROPERTIES



5.1 	Pharmacodynamic properties



Pharmacotherapeutic group: Psychoanaleptics, xanthine derivatives, ATC code: N06BC01



Mechanism of action



Caffeine is structurally related to the methylxanthines theophylline and theobromine.

Most of its effects have been attributed to antagonism of adenosine receptors, both A1 and A2A subtypes, demonstrated in receptor binding assays and observed at concentrations approximating those achieved therapeutically in this indication.



Pharmacodynamic effects



Caffeine’s main action is as a CNS stimulant. This is the basis of caffeine’s effect in apnoea of prematurity, for which several mechanisms have been proposed for its actions including: (1) respiratory centre stimulation, (2) increased minute ventilation, (3) decreased threshold to hypercapnia, (4) increased response to hypercapnia, (5) increased skeletal muscle tone, (6) decreased diaphragmatic fatigue, (7) increased metabolic rate, and (8) increased oxygen consumption.



Clinical efficacy and safety



The clinical efficacy of caffeine citrate was assessed in a multicentre, randomised, double-blind study that compared caffeine citrate to placebo in 85 preterm infants (gestational age 28 to <33 weeks) with apnoea of prematurity. Infants received 20 mg/kg caffeine citrate loading dose intravenously. A maintenance daily dose of 5 mg/kg caffeine citrate was then administered either intravenously or orally (through a feeding tube) for up to 10-12 days. The protocol allowed infants to be “rescued” with open-label caffeine citrate treatment if their apnoea remained uncontrolled. In that case, infants received a second loading dose of 20 mg/kg caffeine citrate after treatment day 1 and before treatment day 8.

There were more days without any apnoea under caffeine citrate treatment (3.0 days, versus 1.2 days for placebo; p=0.005); also, there was a higher percentage of patients with no apnoeas for ≥ 8 days (caffeine 22% versus placebo 0%).

A recent large placebo-controlled multicentre study (n=2006) investigated short-term and long-term (18-21 months) outcomes of premature infants treated with caffeine citrate. Infants randomised to caffeine citrate received an intravenous loading dose of 20 mg/kg, followed by a daily maintenance dose of 5 mg/kg. If apnoeas persisted, the daily maintenance dose could be increased to a maximum of 10 mg/kg of caffeine citrate. The maintenance doses were adjusted weekly for changes in body weight and could be given orally once an infant tolerated full enteral feedings. Caffeine therapy reduced the rate of bronchopulmonary dysplasia [odds ratio (95% CI) 0.63 (0.52 to 0.76)] and improved the rate of survival without neurodevelopmental disability [odds ratio (95 %CI) 0.77 (0.64 to 0.93)].

The size and direction of caffeine effect on death and disability differed depending on the degree of respiratory support infants needed at randomisation, indicating more benefit for the supported infants [odds ratio (95%CI) for death and disability, see table below].



Death or disability according to subgroup of respiratory support at entry to study

		Subgroups

		Odds ratio (95% CI)



		No support

		1.32 (0.81 to 2.14)

		0.73 (0.57 to 0.94)







5.2	Pharmacokinetic properties



Caffeine citrate readily dissociates in aqueous solution. The citrate moiety is rapidly metabolized on infusion or ingestion.



Absorption



The onset of action of caffeine from caffeine citrate is within minutes of commencement of infusion. After oral administration of 10 mg caffeine base/kg body weight to preterm newborn infants, the peak plasma caffeine concentration (Cmax) ranged from 6 to 10 mg/l and the mean time to reach peak concentration (tmax) ranged from 30 min to 2 h. The extent of absorption is not affected by formula feeding but tmax may be prolonged.



Distribution



Caffeine is rapidly distributed into the brain following caffeine citrate administration. Caffeine concentrations in the cerebrospinal fluid of preterm newborn infants approximate to their plasma levels. The mean volume of distribution (Vd) of caffeine in infants (0.8-0.9 l/kg) is slightly higher than that in adults (0.6 l/kg). Plasma protein binding data are not available for newborn infants or infants. In adults, the mean plasma protein binding in vitro is reported to be approximately 36%.



Caffeine readily crosses the placenta into the foetal circulation and is excreted into breast milk.



Biotransformation



Caffeine metabolism in preterm newborn infants is very limited due to their immature hepatic enzyme systems and most of the active substance is eliminated in urine. Hepatic cytochrome P450 1A2 (CYP1A2) is involved in caffeine biotransformation in older individuals.

Inter-conversion between caffeine and theophylline has been reported in preterm newborn infants; caffeine levels are approximately 25% of theophylline levels after theophylline administration and approximately 3-8% of caffeine administered would be expected to convert to theophylline.



Elimination



In young infants, the elimination of caffeine is much slower than that in adults due to immature hepatic and/or renal function. In newborn infants, caffeine clearance is almost entirely by renal excretion. Mean half-life (t1/2) and fraction excreted unchanged in urine (Ae) of caffeine in infants are inversely related to gestational / postmenstrual age. In newborn infants, the t1/2 is approximately 3-4 days and the Ae is approximately 86% (within 6 days). By 9 months of age, the metabolism of caffeine approximates to that seen in adults (t1/2 = 5 hours and Ae = 1%).

Studies examining the pharmacokinetics of caffeine in newborn infants with hepatic or renal insufficiency have not been conducted.

In the presence of significant renal impairment, considering the increased potential for accumulation, a reduced daily maintenance dose of caffeine is required and the doses should be guided by blood caffeine measurements. In premature infants with cholestatic hepatitis a prolonged caffeine elimination half-life with an increase of plasma levels above the normal limit of variation has been found suggesting a particular caution in the dosage of these patients (see sections 4.2 and 4.4).



5.3	Preclinical safety data



Non-clinical data revealed no major hazard for humans based on studies of repeated dose toxicity of caffeine. However, at high doses convulsions in rodents were induced. At therapeutic doses some behavioural changes in newborn rats were induced, most likely as a consequence of increased adenosine receptor expression that persisted into adulthood. Caffeine was shown to be devoid of mutagenic and oncogenic risk. Teratogenic potential and effects on reproductive performance observed in animals are not relevant to its indication in the preterm infant population.

B. PACKAGE LEAFLET


Package leaflet: Information for the user



Gencebok 10 mg/ml solution for infusion 

caffeine citrate



Read all of this leaflet carefully before treatment with this medicine because it contains important information for your newborn

· Keep this leaflet. You may need to read it again. 

· If you have any further questions, please ask your baby’s doctor.

· If your newborn gets any side effects, talk to your baby’s doctor. This includes any possible side effects not listed in this leaflet. See section 4.



What is in this leaflet



1.	What Gencebok is and what it is used for 

2.	What you need to know before your baby is given Gencebok

3.	How to use Gencebok

4.	Possible side effects 

5.	How to store Gencebok

6.	Contents of the pack and other information





1.	What Gencebok is and what it is used for



Gencebok contains the active substance caffeine citrate, which is a stimulant of the central nervous system, belonging to a group of medicines called methylxanthines.



Gencebok is used in the treatment of interrupted breathing in premature babies (primary apnoea of premature newborns).

These short periods when premature babies stop breathing are due to the baby’s breathing centres not being fully developed.

This medicine has been shown to reduce the number of episodes of interrupted breathing in premature newborns.





2.	What you need to know before your baby is given Gencebok



Do not use Gencebok

· If your newborn is allergic to caffeine citrate or any of the other ingredients of this medicine (listed in section 6).



Warnings and precautions 

Talk to your baby’s doctor before your newborn is given Gencebok.

Prior to starting treatment for apnoea of prematurity with Gencebok other causes of apnoea should have been excluded or properly treated by your baby’s doctor.



Gencebok should be used with caution. Please inform your baby’s doctor:



· If your newborn suffers from seizures

· If your newborn suffers from any heart disease

· If your newborn has kidney or liver problems

· If your newborn has frequent regurgitation

· If your newborn produces more urine than usual

· If your newborn has a reduced weight gain or food intake

· If you (the mother) consumed caffeine prior to delivery



Other medicines and Gencebok

Tell your baby’s doctor if your newborn is taking, have recently taken or might take any other medicines.

Please inform your baby’s doctor if your newborn has been previously treated with theophylline.  Do not use the following medicines during the treatment with Gencebok without talking to your baby’s doctor. The doctor may need to adjust the dose or change one of the medicines to something else:

-	theophylline (used to treat breathing difficulties)

-	doxapram (used to treat breathing difficulties)

-	cimetidine (used to treat gastric disease)

-	ketoconazole (used to treat fungine infections)

-	phenobarbital (used to treat epilepsy)

-	phenytoin (used to treat epilepsy)



This medicine may increase the risk for serious intestinal disease with bloody stools (necrotising enterocolitis) when administered with medicines used to treat gastric disease (such as antihistamine H2 receptor blockers or proton-pump inhibitors that reduces gastric acid secretion).



Pregnancy and breast-feeding 

If you (the mother) are breast-feeding while your infant is treated with Gencebok, you should not drink coffee or take any other high caffeine product as caffeine passes into breast milk.



Gencebok contains sodium

This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e. is essentially ‘sodium-free’.



3.	How to use Gencebok



Gencebok should only be used in a neonatal intensive care unit in which adequate facilities are available for patient surveillance and monitoring. Treatment should be initiated under supervision of a physician experienced in neonatal intensive care.



Dose

Your baby’s doctor will prescribe the right amount of Gencebok based on your baby’s weight. The starting dose is 20 mg per kg body weight (equivalent to 2 ml per kg body weight).

The maintenance dose is 5 mg per kg body weight (equivalent to 0.5 ml per kg body weight) every 24 hours.



Route and method of administration

Gencebok will be infused by controlled intravenous infusion, using a syringe infusion pump or other metered infusion device. This method is also known as “a drip”.

Some of the doses (maintenance doses) may be given by mouth.

It may be needed that your baby’s doctor decides to check the levels of caffeine in a blood test periodically throughout treatment to avoid toxicity.



Duration of treatment

Your baby’s doctor will decide exactly how long your newborn must continue therapy with Gencebok.

If your baby has 5 to 7 days without apnoea attacks, the doctor will stop the treatment.



If your newborn receives more Gencebok than he/she should

Your newborn may experience fever, rapid breathing (tachypnoea), jitteriness, muscular tremor vomiting, high blood levels of sugar (hyperglycemia), low blood levels of potassium (hypokalaemia), high blood levels of certain chemicals (urea), elevated number of certain cells (leukocyte) in blood and seizures if he/she receives more caffeine citrate than he/she should.

In the event of this happening treatment with Gencebok should be stopped immediately and your baby’s doctor should treat the overdose.



If you have any further questions on the use of this medicinal product, ask your baby’s doctor.





4.	Possible side effects



Like all medicines, this medicine can cause side effects, although not everybody gets them. However, it is difficult to distinguish them from frequent complications occurring in premature babies and complications due to the disease.



While under treatment with Gencebok, your newborn may experience some of the following reactions:



Serious side effects

Side effects where the frequency cannot be estimated from the available data

· serious intestinal disease with bloody stools (necrotising enterocolitis)



The following other side effects may also be considered serious by your baby’s doctor in the context of the global clinical evaluation.



Other side effects



Common reported side effects (may affect up to 1 in 10 people)

-	local inflammatory reactions at the infusion site

-	cardiac disorders such as fast heart beat (tachycardia)

-	changes of sugar in blood or serum (hyperglycaemia)



Uncommon reported side effects (may affect up to 1 in 100 people)

-	stimulation of central nervous system such as convulsion

-	cardiac disorders such as irregular heart beat (arrhythmia)



Rare reported side effects (may affect up to 1 in 1,000 people)

-	allergic reactions

{'Title': '4. possible side effects', 'Section_Content': "like all medicines, this medicine can cause side effects, although not everybody gets them. however, it is difficult to distinguish them from frequent complications occurring in premature babies and complications due to the disease. while under treatment with gencebok, your newborn may experience some of the following reactions: serious side effects side effects where the frequency cannot be estimated from the available data - serious intestinal disease with bloody stools (necrotising enterocolitis) the following other side effects may also be considered serious by your baby's doctor in the context of the global clinical evaluation. other side effects common reported side effects (may affect up to 1 in 10 people) - local inflammatory reactions at the infusion site - cardiac disorders such as fast heart beat (tachycardia) - changes of sugar in blood or serum (hyperglycaemia) uncommon reported side effects (may affect up to 1 in 100 people) - stimulation of central nervous system such as convulsion - cardiac disorders such as irregular heart beat (arrhythmia) rare reported side effects (may affect up to 1 in 1,000 people) - allergic reactions side effects where the frequency cannot be estimated from the available data - bloodstream infection (sepsis) - changes of sugar in blood or serum (hypoglycaemia ), failure to grow, feeding intolerance - stimulation of central nervous system such as irritability, nervousness and restlessness; brain injury - deafness - regurgitation, increase in stomach aspirate - increase of urine flow, increase of certain urine components (sodium and calcium) - changes in blood tests (reduced levels of haemoglobin after prolonged treatment and reduced thyroid hormone at the start of treatment) reporting of side effects if your newborn gets any side effects, talk to your baby's doctor. this includes any possible side effects not listed in this leaflet. you can also report side effects directly via the national reporting system listed in appendix v. by reporting side effects, you can help provide more information on the safety of this medicine.", 'Entity_Recognition':
