The potency (IU) is determined using the European Pharmacopoeia one-stage clotting assay. The 
specific activity of BeneFIX is not less than 200 IU/mg protein. 
 
BeneFIX contains recombinant coagulation factor IX, (INN = nonacog alfa). Nonacog alfa is a 
purified protein that has 415 amino acids in a single chain. It has a primary amino acid sequence that is 
comparable to the Ala148 allelic form of plasma-derived factor IX, and some post-translational 
modifications of the recombinant molecule are different from those of the plasma-derived molecule. 
Recombinant coagulation factor IX is a glycoprotein that is secreted by genetically engineered 
mammalian cells derived from a Chinese hamster ovary (CHO) cell line.

4. CLINICAL PARTICULARS 

 
4.1 Therapeutic indications 

 
Treatment and prophylaxis of bleeding in patients with haemophilia B (congenital factor IX 
deficiency). 
 
BeneFIX can be used for all age groups. 
 
4.2 Posology and method of administration 

 
Treatment should be under the supervision of a physician experienced in the treatment of haemophilia. 
 
Treatment monitoring 
During the course of treatment, appropriate determination of factor IX levels is advised to guide the 
dose to be administered and the frequency of repeated infusions. Individual patients may vary in their 
response to factor IX, demonstrating different half-lives and recoveries. Dose based on bodyweight 
may require adjustment in underweight or overweight patients. In the case of major surgical 
interventions in particular, precise monitoring of the substitution therapy by means of coagulation 
analysis (plasma factor IX activity) is indispensable. 
 
When using an in vitro thromboplastin time (aPTT)-based one stage clotting assay for determining 
factor IX activity in patients’ blood samples, plasma factor IX activity results can be significantly 
affected by both the type of aPTT reagent and the reference standard used in the assay. This is of 
importance particularly when changing the laboratory and/or reagents used in the assay. 
 
Posology 
Dose and duration of the substitution therapy depend on the severity of the factor IX deficiency, on the 
location and extent of bleeding, and on the patient's clinical condition. 
 
The number of units of factor IX administered is expressed in International Units (IU), which is related 
to the current WHO standard for factor IX products. Factor IX activity in plasma is expressed either as 
a percentage (relative to normal human plasma) or in International Units (relative to an international 
standard for factor IX in plasma). 
 
One International Unit (IU) of factor IX activity is equivalent to that quantity of factor IX in one mL 
of normal human plasma. 
 
On demand treatment 

The calculation of the required dose of BeneFIX can be based on the finding that one unit of factor IX 
activity per kg body weight is expected to increase the circulating level of factor IX, an average of 
0.8 IU/dL (range from 0.4 to 1.4 IU/dL) in patients  12 years (further information in section 5.2). 
 
The required dose is determined using the following formula: 
 
Number of 
factor IX IU 
required 

= body weight (in kg) X desired factor IX 
increase (%) or (IU/dL) 

X reciprocal of 
observed recovery 

 



 

4 

Example: For a recovery of 0.8 IU/dL, the formula reads: 
 
Number of 
factor IX IU 
required 

= body weight (in kg) X desired factor IX 
increase (%) or (IU/dL) 

X 1.3 IU/kg 

 
The amount to be administered and the frequency of administration should always be oriented to the 
clinical effectiveness in the individual case. 
 
In the case of the following haemorrhagic events, the factor IX activity should not fall below the given 
plasma activity levels (in % of normal or in IU/dL) in the corresponding period. The following table 
can be used to guide dosing in bleeding episodes and surgery:

Repeat infusion every 8-24 hours until 
adequate wound healing, then therapy for at 
least another 7 days to maintain a factor IX 
activity of 30% to 60% (IU/dL) 
 

 
Prophylaxis 

BeneFIX may be administered for long term prophylaxis against bleeding in patients with severe 
haemophilia B. In a clinical study for routine secondary prophylaxis the average dose for previously 
treated patients (PTP) was 40 IU/kg (range 13 to 78 IU/kg) at intervals of 3 to 4 days. 
 
In some cases, especially in younger patients, shorter dosage intervals or higher doses may be 
necessary. 
 
Paediatric population 
There is limited documentation of on-demand treatment and surgery in paediatric patients less than 
6 years of age treated with BeneFIX. 
 
Mean dosage ( standard deviation) for prophylaxis was 63.7 ( 19.1) IU/kg at intervals of 3 to 
7 days. In younger patients, shorter dosage intervals or higher doses may be necessary. FIX 
consumption for routine prophylaxis in 22 evaluable patients was 4607 ( 1849) IU/kg per year and 
378 ( 152) IU/kg per month. 



 

5 

 
Close monitoring of factor IX plasma activity should be performed as clinically indicated, as well as 
calculation of pharmacokinetic parameters such as recovery and half-life, in order to adjust doses as 
appropriate. 
 
Elderly population 
Clinical studies of BeneFIX did not include sufficient numbers of subjects aged 65 and over to 
determine whether they respond differently from younger subjects. As with any patient receiving 
BeneFIX, dose selection for an elderly patient should be individualised. 
 
Method of administration 
BeneFIX is administered by intravenous infusion after reconstitution of the lyophilised powder for 
solution for injection with sterile 0.234% sodium chloride solution (see section 6.6). 
 
BeneFIX should be administered at a slow infusion rate. In most of the cases, an infusion rate of up to 
4 mL per minute has been used. The rate of administration should be determined by the patient’s 
comfort level. 
 
If any suspected hypersensitivity reaction takes place that is thought to be related to the administration 
of BeneFIX, the rate of infusion should be decreased or the infusion stopped (see sections 4.4 and 4.8). 
 
Agglutination of red blood cells in the tube/syringe 
There have been reports of agglutination of red blood cells in the tube/syringe with the administration 
of BeneFIX. No adverse events have been reported in association with this observation. To minimize 
the possibility of agglutination, it is important to limit the amount of blood entering the tubing. Blood 
should not enter the syringe. If agglutination of red blood cells in the tubing/syringe is observed, 
discard all this material (tubing, syringe and BeneFIX solution) and resume administration with a new 
package. 
 
Continuous infusion 
Administration by continuous infusion has not been approved and is not recommended (see also 
sections 4.4 and 6.6). 
 
For instructions on reconstitution of the medicinal product before administration, see section 6.6. 
 
4.3 Contraindications 

 
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. 
 
Known allergic reaction to hamster proteins. 
 
4.4 Special warnings and precautions for use 

 
Hypersensitivity 
Allergic-type hypersensitivity reactions are possible with BeneFIX. The product contains traces of 
hamster proteins. Potentially life-threatening anaphylactic/anaphylactoid reactions have occurred with 
factor IX products, including BeneFIX. If symptoms of hypersensitivity occur, patients should be 
advised to discontinue use of the medicinal product immediately and contact their physician. Patients 
should be informed of early signs of hypersensitivity reactions including difficult breathing, shortness 
of breath, swelling, hives, generalised urticaria, itching, tightness of the chest, bronchospasm, 
laryngospasm, wheezing, hypotension, blurred vision, and anaphylaxis. 
 
In some cases, these reactions have progressed to severe anaphylaxis. In the case of shock, the current 
medical standards for treatment of shock should be observed. In case of severe allergic reactions, 
alternative haemostatic measures should be considered. 
 



 

6 

Inhibitors 
Inhibitors are an uncommon event in previously treated patients (PTPs) receiving factor IX-containing 
products. As one PTP treated with BeneFIX developed a clinically relevant low responding inhibitor 
during clinical studies and experience on antigenicity with recombinant factor IX is still limited, 
patients treated with BeneFIX should be carefully monitored for the development of factor IX 
inhibitors that should be titrated in Bethesda Units using appropriate biological testing. 
 
There have been reports in the literature showing a correlation between the occurrence of a factor IX 
inhibitor and allergic reactions. Therefore, patients experiencing allergic reactions should be evaluated 
for the presence of an inhibitor. It should be noted that patients with factor IX inhibitors may be at an 
increased risk of anaphylaxis with subsequent challenge with factor IX. Preliminary information 
suggests a relationship may exist between the presence of major deletion mutations in a patient's factor 
IX gene and an increased risk of inhibitor formation and of acute hypersensitivity reactions. Patients 
known to have major deletion mutations of the factor IX gene should be observed closely for signs and 
symptoms of acute hypersensitivity reactions, particularly during the early phases of initial exposure 
to product. 
 
Because of the risk of allergic reactions with factor IX concentrates, the initial administrations of 
factor IX should, according to the treating physician’s judgement, be performed under medical 
observation where proper medical care for allergic reactions could be provided. 
 
Thrombosis 
Although BeneFIX contains only factor IX, the risk of thrombosis and disseminated intravascular 
coagulation (DIC) should be recognised. Since the use of factor IX complex concentrates has 
historically been associated with the development of thromboembolic complications, the use of factor 
IX-containing products may be potentially hazardous in patients with signs of fibrinolysis and in 
patients with disseminated intravascular coagulation (DIC). Because of the potential risk of 
thrombotic complications, clinical surveillance for early signs of thrombotic and consumptive 
coagulopathy should be initiated with appropriate biological testing when administering this product 
to patients with liver disease, to patients post-operatively, to new-born infants, or to patients at risk of 
thrombotic phenomena or DIC. In each of these situations, the benefit of treatment with BeneFIX 
should be weighed against the risk of these complications. 
 
The safety and efficacy of BeneFIX administration by continuous infusion have not been established 
(see also sections 4.2 and 4.8). There have been post-marketing reports of thrombotic events, including 
life-threatening superior vena cava (SVC) syndrome in critically ill neonates, while receiving 
continuous-infusion BeneFIX through a central venous catheter (see also section 4.8). 
 
Cardiovascular events 
In patients with existing cardiovascular risk factors, substitution therapy with FIX may increase the 
cardiovascular risk. 
 
Nephrotic syndrome 
Nephrotic syndrome has been reported following attempted immune tolerance induction in 
haemophilia B patients with factor IX inhibitors and a history of allergic reaction. The safety and 
efficacy of using BeneFIX for immune tolerance induction has not been established. 
 
Special populations 
Sufficient data have not been obtained from clinical studies on the treatment of previously untreated 
patients (PUPs) with BeneFIX. 
 
Record of use 
It is strongly recommended that every time BeneFIX is administered to a patient, the name and batch 
number of the product are recorded in order to maintain a link between the patient and the batch of the 
medicinal product. Patients can affix one of the peel-off labels found on the vial to document the batch 
number in their diary or for reporting any side effects.

4.5 Interaction with other medicinal products and other forms of interaction 

 
No interactions of human coagulation factor IX (rDNA) products with other medicinal products have 
been reported. 
 
4.6 Fertility, pregnancy and lactation 

 
Animal reproduction studies have not been conducted with factor IX. Based on the rare occurrence of 
haemophilia B in women, experience regarding the use of factor IX during pregnancy and 
breastfeeding is not available. Therefore, factor IX should be used during pregnancy and 
breast-feeding only if clearly indicated. 
 
The effect of BeneFIX on fertility has not been established. 
 
4.7 Effects on ability to drive and use machines 

 
BeneFIX has no influence on the ability to drive or use machines. 
 
4.8 Undesirable effects 

 
Summary of the safety profile 
Hypersensitivity or allergic reactions (which may include angioedema, burning and stinging at the 
infusion site, chills, flushing, generalised urticaria, headache, hives, hypotension, lethargy, nausea, 
restlessness, tachycardia, tightness of the chest, tingling, vomiting, wheezing) have been observed and 
may in some cases progress to severe anaphylaxis (including shock). In some cases, these reactions 
have progressed to severe anaphylaxis, and they have occurred in close temporal association with 
development of factor IX inhibitors (see also section 4.4). Nephrotic syndrome has been reported 
following attempted immune tolerance induction in haemophilia B patients with factor IX inhibitors 
and a history of allergic reaction. 
 
Very rarely development of antibodies to hamster protein with related hypersensitivity reactions has 
been observed. 
 
Patients with haemophilia B may develop neutralising antibodies (inhibitors) to factor IX. If such 
inhibitors occur, the condition will manifest itself as an insufficient clinical response. In such cases, it 
is recommended that a specialised haemophilia centre be contacted. 
 
There is a potential risk of thromboembolic episodes following the administration of factor IX 
products, see section 4.4.

Description of selected adverse reactions 
 
Hypersensitivity/allergic reactions 

If any suspected hypersensitivity reaction takes place that is thought to be related to the administration 
of BeneFIX see sections 4.2 and 4.4. 
 
Inhibitor development 

A clinically relevant, low responding inhibitor was detected in 1 out of 65 BeneFIX patients 
(including 9 patients participating only in the surgery study) who had previously received plasma-
derived products. This patient was able to continue treatment with BeneFIX with no anamnestic rise in 
inhibitor or anaphylaxis (see section 4.4). 
 
Paediatric population 
Allergic reactions might be experienced more frequently in children than in adults. 
 
There are insufficient data to provide information on inhibitor incidence in PUPs (see also 
section 5.1). 
 
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 

 
No symptoms of overdose have been reported with recombinant coagulation factor IX products. 
 
 
5. PHARMACOLOGICAL PROPERTIES 

 
5.1  Pharmacodynamic properties 

 
Pharmacotherapeutic group: Antihaemorrhagics, blood coagulation factor IX; ATC code: B02BD04 
 
Mechanism of action 
BeneFIX contains recombinant coagulation factor IX, (nonacog alfa). Recombinant coagulation 
factor IX is a single chain glycoprotein with an approximate molecular mass of 55,000 Daltons that is 
a member of the serine protease family of vitamin K-dependent coagulation factors. Recombinant 
coagulation factor IX is a recombinant DNA-based protein therapeutic which has structural and 
functional characteristics comparable to endogenous factor IX. Factor IX is activated by 
factor VII/tissue factor complex in the extrinsic pathway as well as factor XIa in the intrinsic 
coagulation pathway. Activated factor IX, in combination with activated factor VIII, activates 
factor X. This results ultimately in the conversion of prothrombin to thrombin. Thrombin then 
converts fibrinogen into fibrin and a clot can be formed. Factor IX activity is absent or greatly reduced 
in patients with haemophilia B and substitution therapy may be required. 
 
Pharmacodynamic effects 
Haemophilia B is a sex-linked hereditary disorder of blood coagulation due to decreased levels of 
factor IX and results in profuse bleeding into joints, muscles or internal organs, either spontaneously 
or as a result of accidental or surgical trauma. By replacement therapy the plasma levels of factor IX is 
increased, thereby enabling a temporary correction of the factor deficiency and correction of the 
bleeding tendencies. 
 
Paediatric population 
Efficacy analysis in study 3090A1-301-WW was based on 22 evaluable paediatric subjects on 
prophylaxis regimen including 4 on-demand patients who shortly changed to prophylaxis. Two 



 

10 

patients underwent surgical procedures (circumcision and port-a-catheter insertion). Safety analysis of 
25 evaluable patients reflected a safety profile as expected. The only documented serious adverse 
event related with BeneFIX was reported from the only included PUP, who experienced 
hypersensitivity and inhibitor development. 
 
In two open-label studies BeneFIX was found to be safely administered at 100 IU/kg once-weekly. 
However, the half-life of the product (see section 5.2) and the limited pharmacokinetic study data for 
the once-weekly regimen do not allow recommending this regimen in general for long-term 
prophylaxis in severe haemophilia B patients. 
 
5.2 Pharmacokinetic properties 

 
In a randomized, cross-over pharmacokinetic study, BeneFIX reconstituted in 0.234% sodium chloride 
diluent was shown to be pharmacokinetically equivalent to the previously marketed BeneFIX 
(reconstituted with sterile water) in 24 previously treated patients (≥12 years) at a dose of 75 IU/kg. In 
addition, pharmacokinetic parameters were followed up in 23 of the same patients after repeated 
administration of BeneFIX for six months and found to be unchanged compared with those obtained at 
the initial evaluation. A summary of pharmacokinetic data is presented in Table 1.

A population pharmacokinetic model was developed using data collected in 73 patients aged 7 months 
to 60 years. The parameters estimated using the final 2-compartment model are shown in Table 2. 
Infants and children had higher clearance, larger volume of distribution, shorter half-life and lower 
recovery than adolescents and adults. The terminal phase has not been covered unambiguously due to 
lack of data beyond 24 hours in paediatric subjects < 6 years of age.

BeneFIX, when reconstituted, contains polysorbate-80, which is known to increase the rate of 
di-(2-ethylhexyl)phthalate (DEHP) extraction from polyvinyl chloride (PVC). This should be 
considered during the preparation and administration of BeneFIX. It is important that the

Read all of this leaflet carefully before you start taking this medicine because it contains 

important information for you. 

- Keep this leaflet. You may need to read it again. 
- If you have any further questions, ask your doctor, pharmacist or nurse. 
- This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, 

even if their signs of illness are the same as yours.  
- If you get any side effects talk to your doctor, pharmacist or nurse. This includes any possible side 

effects not listed in this leaflet. See section 4. 
 
What is in this leaflet 

1. What BeneFIX is and what it is used for 
2. What you need to know before you take BeneFIX 
3. How to take BeneFIX 
4. Possible side effects 
5. How to store BeneFIX 
6. Contents of the pack and other information 
 
 
1. What BeneFIX is and what it is used for 
 
BeneFIX is an injectable clotting (coagulation) factor IX product that is produced by recombinant 
DNA technology. The active ingredient in BeneFIX is nonacog alfa. People who are born with 
haemophilia B (Christmas disease) lack sufficient factor IX to control bleeding. BeneFIX works by 
replacing factor IX in haemophilia B patients to enable their blood to clot. 
 
BeneFIX is used for the treatment and prevention of bleeding in patients with haemophilia B 
(congenital factor IX deficiency) in all age groups. 
 
 
2. What you need to know before you take BeneFIX 
 
Do not take BeneFIX: 
 
- If you are allergic to nonacog alfa or any of the other ingredients of this medicine (listed in 

section 6). 
-  If you are allergic to hamster proteins. 
 
Warnings and precautions 
 
- See your doctor immediately if your bleeding does not stop as expected. 
 
- Allergic reactions are possible. The product may contain traces of hamster proteins (see Do not 

take BeneFIX). Potentially life-threatening anaphylactic reactions (severe allergic reactions) 
have occurred with factor IX products, including BeneFIX. Early signs of allergic reactions 
include difficulty breathing, shortness of breath, swelling, hives, itching, generalised urticaria, 
tightness of the chest, wheezing, low blood pressure, blurred vision and anaphylaxis (severe 



 

25 

allergic reaction that can cause difficulty in swallowing and/or breathing, red or swollen face 
and/or hands).  

 
- If allergic or anaphylactic-type reactions occur, stop the infusion immediately and contact a 

doctor or seek emergency medical care immediately. In case of severe allergic reactions, 
alternative therapy should be considered.  

 
- Activity-neutralizing antibodies (inhibitors) are an uncommon event in patients who have 

received previous treatment with factor IX-containing products. However, as with all factor IX 
products you should be carefully monitored for the development of factor IX inhibitors while 
being treated with BeneFIX.  

 
- Research has shown a link between the occurrence of a factor IX inhibitor and allergic 

reactions. Therefore, if you experience allergic reactions such as those described above, you 
should be tested for the presence of an inhibitor. It should be noted that patients with a factor IX 
inhibitor may be at an increased risk of anaphylaxis during future treatment with BeneFIX. 
 

- The production of factor IX in the body is controlled by the factor IX gene. Patients who have 
specific mutations of their factor IX gene such as major deletion may be more likely to develop 
an inhibitor to factor IX and/or experience allergic reactions. Therefore if you are known to 
have such a mutation your doctor may monitor you more closely for signs of an allergic 
reaction particularly when you first start to take BeneFIX. 

 
- Because of the risk of allergic reactions with factor IX, your initial administrations of BeneFIX 

should be performed under medical observation where proper medical care for allergic reactions 
can be provided. 

 
- Even in the absence of factor IX inhibitor, higher doses of BeneFIX may be needed than 

required for other plasma-derived factor IX products that you may have taken previously. 
Therefore, close monitoring of factor IX plasma activity (which measures the ability of your 
blood to form clots) has to be performed to adjust doses as appropriate. If bleeding is not 
controlled with the recommended dose, contact your doctor. 

 
- If you suffer from liver or heart disease or if you have recently had surgery, there is an 

increased risk for blood clotting (coagulation) complications. 
 
- A kidney disorder (nephrotic syndrome) has been reported following high doses of 

plasma-derived factor IX in haemophilia B patients with factor IX inhibitors and a history of 
allergic reactions. 

 
- Sufficient data have not been obtained from clinical studies on the treatment of previously 

untreated patients (patients who have never received a previous infusion of factor IX), with 
BeneFIX. 
 

- It is recommended that evey time you use BeneFIX, you record the name and batch number of 
the product. You can use one of the peel-off labels found on the vial to document the batch 
number in your diary or for reporting any side effects. 

 
Other medicines and BeneFIX 
 
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other 
medicines. 
 
Pregnancy and breast-feeding 
 
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, you 
should only take BeneFIX upon specific instructions from your doctor. It is not known whether 



 

26 

BeneFIX can cause harm to an unborn baby when given to pregnant women. Your doctor may advise 
you to stop treatment with BeneFIX if you are breast-feeding or become pregnant. 
 
Ask your doctor or pharmacist for advice before taking this medicine. 
 
Driving and using machines 
 
BeneFIX has no influence on the ability to drive or use machines. 
 
 
3. How to take BeneFIX 
 
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor 
or pharmacist if you are not sure. 
 
Your doctor will decide the dose of BeneFIX you will receive. This dose and duration will depend 
upon your individual needs for replacement factor IX therapy and how quickly your body uses up 
factor IX, which will be checked regularly. You may notice a difference in the dose you receive if you 
are changing from a plasma-derived factor IX product to BeneFIX. 
 
Your doctor may decide to change the dose of BeneFIX you receive during your treatment. 
 
Reconstitution and administration  
 
The procedures below are provided as guidelines for the reconstitution and administration of 
BeneFIX. Patients should follow the specific venipuncture procedures provided by their doctor. 
 
BeneFIX is administered by intravenous (IV) infusion after reconstitution of the powder for injection 
with the supplied solvent (a sodium chloride (salt) solution) in the pre-filled syringe. 
 
Always wash your hands prior to performing the following procedures. Aseptic technique (meaning 
clean and germ free) should be used during the reconstitution procedure. 
 
Reconstitution: 
 
BeneFIX will be administered by intravenous infusion (IV) after reconstitution with sterile solvent for 
injection. 
 
1. Allow the vial of lyophilised (freeze-dried) BeneFIX and the pre-filled syringe to reach room 

temperature. 
 
2. Remove the plastic flip-top cap from the BeneFIX vial to expose the central portion of the 

rubber stopper. 

 
 
3. Wipe the top of the vial with an alcohol swab provided, or use another antiseptic solution and 

allow to dry. After cleaning do not touch the rubber stopper with your hand or allow it to touch 
any surface. 

 
4. Peel back the lid from the clear plastic vial adapter package. Do not remove the adapter from the 

package. 
 



 

27 

5. Place the vial on a flat surface. While holding the adapter in the package, place the vial adapter 
over the vial. Press down firmly on the package until the adapter snaps into place on top of the 
vial, with the adapter spike penetrating the vial stopper. 

 

 

6. Lift the package away from the adapter and discard the package. 
 

 
 
7. Attach the plunger rod to the solvent syringe by pushing and turning firmly. 
 
 
8. Break off the tamper-resistant plastic tip cap from the solvent syringe by snapping the 

perforation of the cap. This is done by bending the cap up and down until the perforation is 
broken. Do not touch the inside of the cap or the syringe tip. The cap may need to be replaced 
(if not administering reconstituted BeneFIX immediately), so set it aside by placing it on its top. 

 

 
9. Place the vial on a flat surface. Connect the solvent syringe to the vial adapter by inserting the 

tip of the syringe into the adapter opening while firmly pushing and turning the syringe 
clockwise until the connection is secured. 

 
10. Slowly depress the plunger rod to inject all the solvent into the BeneFIX vial 

 



 

28 

11. With the syringe still connected to the adapter, gently rotate the vial until the powder is 
dissolved. 

 

 

12. The final solution should be inspected visually for fine particles before administration. The 
solution should appear clear and colourless. 

 
 Note: If you use more than one vial of BeneFIX per infusion, each vial should be reconstituted 

as per the previous instructions. The solvent syringe should be removed, leaving the vial adapter 
in place, and a separate large luer lock (a device that connects the syringe to the vial) syringe 
may be used to draw back the reconstituted contents of each individual vial. 

 
13. Ensuring that the syringe plunger rod is still fully depressed, invert the vial. Slowly draw back 

all the solution into the syringe. 
 

 

14. Detach the syringe from the vial adapter by gently pulling and turning the syringe 
counter-clockwise. Discard the vial with the adapter attached. 

 
 Note: If the solution is not to be used immediately, the syringe cap should be carefully replaced. 

Do not touch the syringe tip or the inside of the cap. 
 
BeneFIX should be administered immediately or within 3 hours after reconstitution. The reconstituted 
solution may be stored at room temperature prior to administration. 
 
Administration (Intravenous Injection): 
 
BeneFIX should be administered using the pre-filled solvent syringe provided or a single sterile 
disposable plastic luer lock syringe. In addition, the solution should be withdrawn from the vial using 
the vial adapter. 
 
BeneFIX should be injected intravenously over several minutes. Your doctor may change your 
recommended infusion rate to make the infusion more comfortable. 
 
There have been reports of clumping (agglutination) of red blood cells in the tube/syringe with the 
administration of BeneFIX. No side effects have been reported in association with this observation. To 
minimize the possibility of agglutination, it is important to limit the amount of blood entering the 
tubing. Blood should not enter the syringe. If clumping of red blood cells in the tubing/syringe is 
observed, discard all this material (tubing, syringe and BeneFIX solution) and resume administration 
with a new package. 
 
Because the use of BeneFIX by continuous infusion (drip) has not been evaluated, BeneFIX should 
not be mixed with infusion solutions or be given in a drip. 



 

29 

 
Please dispose of all unused solution, empty vials and used needles and syringes in an appropriate 
container for throwing away waste as it may hurt others if not handled properly. 
 
If you take more BeneFIX than you should 
 
Please contact your doctor immediately if you inject more BeneFIX than your doctor recommends. 
 
If you stop taking BeneFIX 
 
Do not stop taking BeneFIX without consulting your doctor. 
 
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse. 
 
 
4. Possible side effects 
 
Like all medicines, this medicine can cause side effects, although not everybody gets them. 
 
Hypersensitivity/allergic reactions  
 
Allergic-type hypersensitivity reactions are possible with BeneFIX. Such reactions may include 
swelling of the face or throat, burning and stinging at the infusion site, chills, flushing, itching, 
headache, hives, low blood pressure, lethargy, nausea, restlessness, fast heart rate, tightness of the 
chest, tingling, vomiting, wheezing). In some cases, these reactions have progressed to severe 
anaphylaxis. Allergic reactions may occur together with the development of factor IX inhibitor (see 
also “Warnings and precautions”). 
 
These reactions are potentially life-threatening. If allergic/anaphylactic reactions occur, stop the 
infusion immediately and contact your doctor or seek emergency medical care immediately. The 
treatment required depends on the nature and severity of side-effects (see also “Warnings and 
precautions”).  
 
Inhibitor development 
 
Patients with haemophilia B may develop neutralising antibodies (inhibitors) to factor IX. If such 
inhibitors occur, a sign may be an increase in the amount of BeneFIX typically required to treat a 
bleed and or continued bleeding after treatment. In such cases, it is recommended that a specialised 
haemophilia centre be contacted. Your doctor may want to monitor you for inhibitor development (see 
“Warnings and precautions”). 
 
A kidney disorder has been reported following high doses of plasma-derived factor IX to induce 
immune tolerance in haemophilia B patients with factor IX inhibitors and a history of allergic 
reactions (see also “Warnings and precautions”). 
 
Thrombotic events 
 
BeneFIX may increase the risk of thrombosis (abnormal blood clots) in your body if you have risk 
factors for developing blood clots, including an indwelling venous catheter. There have been reports 
of severe blood clotting events, including life-threatening blood clots in critically ill babies, while 
receiving continuous-infusion BeneFIX through a central venous catheter. Cases of peripheral 
thrombophlebitis (pain and redness of the veins) and deep venous thrombosis (blood clots in the 
extremities) have also been reported; in most of these cases, BeneFIX was administered via continuous 
infusion, which is not an approved method of administration.

{'Title': '2. what you need to know before you take benefix', 'Section_Content': 'do not take benefix: - if you are allergic to nonacog alfa or any of the other ingredients of this medicine (listed in section 6). - if you are allergic to hamster proteins. warnings and precautions - see your doctor immediately if your bleeding does not stop as expected. - allergic reactions are possible. the product may contain traces of hamster proteins (see do not take benefix). potentially life-threatening anaphylactic reactions (severe allergic reactions) have occurred with factor ix products, including benefix. early signs of allergic reactions include difficulty breathing, shortness of breath, swelling, hives, itching, generalised urticaria, tightness of the chest, wheezing, low blood pressure, blurred vision and anaphylaxis (severe 25 allergic reaction that can cause difficulty in swallowing and/or breathing, red or swollen face and/or hands). - if allergic or anaphylactic-type reactions occur, stop the infusion immediately and contact a doctor or seek emergency medical care immediately. in case of severe allergic reactions, alternative therapy should be considered. - activity-neutralizing antibodies (inhibitors) are an uncommon event in patients who have received previous treatment with factor ix-containing products. however, as with all factor ix products you should be carefully monitored for the development of factor ix inhibitors while being treated with benefix. - research has shown a link between the occurrence of a factor ix inhibitor and allergic reactions. therefore, if you experience allergic reactions such as those described above, you should be tested for the presence of an inhibitor. it should be noted that patients with a factor ix inhibitor may be at an increased risk of anaphylaxis during future treatment with benefix. - the production of factor ix in the body is controlled by the factor ix gene. patients who have specific mutations of their factor ix gene such as major deletion may be more likely to develop an inhibitor to factor ix and/or experience allergic reactions. therefore if you are known to have such a mutation your doctor may monitor you more closely for signs of an allergic reaction particularly when you first start to take benefix. - because of the risk of allergic reactions with factor ix, your initial administrations of benefix should be performed under medical observation where proper medical care for allergic reactions can be provided. - even in the absence of factor ix inhibitor, higher doses of benefix may be needed than required for other plasma-derived factor ix products that you may have taken previously. therefore, close monitoring of factor ix plasma activity (which measures the ability of your blood to form clots) has to be performed to adjust doses as appropriate. if bleeding is not controlled with the recommended dose, contact your doctor. - if you suffer from liver or heart disease or if you have recently had surgery, there is an increased risk for blood clotting (coagulation) complications. - a kidney disorder (nephrotic syndrome) has been reported following high doses of plasma-derived factor ix in haemophilia b patients with factor ix inhibitors and a history of allergic reactions. - sufficient data have not been obtained from clinical studies on the treatment of previously untreated patients (patients who have never received a previous infusion of factor ix), with benefix. - it is recommended that evey time you use benefix, you record the name and batch number of the product. you can use one of the peel-off labels found on the vial to document the batch number in your diary or for reporting any side effects. other medicines and benefix tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. pregnancy and breast-feeding if you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, you should only take benefix upon specific instructions from your doctor. it is not known whether 26 benefix can cause harm to an unborn baby when given to pregnant women. your doctor may advise you to stop treatment with benefix if you are breast-feeding or become pregnant. ask your doctor or pharmacist for advice before taking this medicine. driving and using machines benefix has no influence on the ability to drive or use machines.', 'Entity_Recognition': [{'Text': 'benefix', 'Type': 'PRODUCT_NAME', 'BeginOffset': 0, 'EndOffset': 0}, {'Id': 3, 'BeginOffset': 12,

{'Title': '3. how to take benefix', 'Section_Content': 'always take this medicine exactly as your doctor or pharmacist has told you. check with your doctor or pharmacist if you are not sure. your doctor will decide the dose of benefix you will receive. this dose and duration will depend upon your individual needs for replacement factor ix therapy and how quickly your body uses up factor ix, which will be checked regularly. you may notice a difference in the dose you receive if you are changing from a plasma-derived factor ix product to benefix. your doctor may decide to change the dose of benefix you receive during your treatment. reconstitution and administration the procedures below are provided as guidelines for the reconstitution and administration of benefix. patients should follow the specific venipuncture procedures provided by their doctor. benefix is administered by intravenous (iv) infusion after reconstitution of the powder for injection with the supplied solvent (a sodium chloride (salt) solution) in the pre-filled syringe. always wash your hands prior to performing the following procedures. aseptic technique (meaning clean and germ free) should be used during the reconstitution procedure. reconstitution: benefix will be administered by intravenous infusion (iv) after reconstitution with sterile solvent for injection. 1. allow the vial of lyophilised (freeze-dried) benefix and the pre-filled syringe to reach room temperature. 2. remove the plastic flip-top cap from the benefix vial to expose the central portion of the rubber stopper. 3. wipe the top of the vial with an alcohol swab provided, or use another antiseptic solution and allow to dry. after cleaning do not touch the rubber stopper with your hand or allow it to touch any surface. 4. peel back the lid from the clear plastic vial adapter package. do not remove the adapter from the package. 5. place the vial on a flat surface. while holding the adapter in the package, place the vial adapter over the vial. press down firmly on the package until the adapter snaps into place on top of the vial, with the adapter spike penetrating the vial stopper. 6. lift the package away from the adapter and discard the package. 7. attach the plunger rod to the solvent syringe by pushing and turning firmly. 8. break off the tamper-resistant plastic tip cap from the solvent syringe by snapping the perforation of the cap. this is done by bending the cap up and down until the perforation is broken. do not touch the inside of the cap or the syringe tip. the cap may need to be replaced (if not administering reconstituted benefix immediately), so set it aside by placing it on its top. 9. place the vial on a flat surface. connect the solvent syringe to the vial adapter by inserting the tip of the syringe into the adapter opening while firmly pushing and turning the syringe clockwise until the connection is secured. 10. slowly depress the plunger rod to inject all the solvent into the benefix vial 28 11. with the syringe still connected to the adapter, gently rotate the vial until the powder is dissolved. 12. the final solution should be inspected visually for fine particles before administration. the solution should appear clear and colourless. note: if you use more than one vial of benefix per infusion, each vial should be reconstituted as per the previous instructions. the solvent syringe should be removed, leaving the vial adapter in place, and a separate large luer lock (a device that connects the syringe to the vial) syringe may be used to draw back the reconstituted contents of each individual vial. 13. ensuring that the syringe plunger rod is still fully depressed, invert the vial. slowly draw back all the solution into the syringe. 14. detach the syringe from the vial adapter by gently pulling and turning the syringe counter-clockwise. discard the vial with the adapter attached. note: if the solution is not to be used immediately, the syringe cap should be carefully replaced. do not touch the syringe tip or the inside of the cap. benefix should be administered immediately or within 3 hours after reconstitution. the reconstituted solution may be stored at room temperature prior to administration. administration (intravenous injection): benefix should be administered using the pre-filled solvent syringe provided or a single sterile disposable plastic luer lock syringe. in addition, the solution should be withdrawn from the vial using the vial adapter. benefix should be injected intravenously over several minutes. your doctor may change your recommended infusion rate to make the infusion more comfortable. there have been reports of clumping (agglutination) of red blood cells in the tube/syringe with the administration of benefix. no side effects have been reported in association with this observation. to minimize the possibility of agglutination, it is important to limit the amount of blood entering the tubing. blood should not enter the syringe. if clumping of red blood cells in the tubing/syringe is observed, discard all this material (tubing, syringe and benefix solution) and resume administration with a new package. because the use of benefix by continuous infusion (drip) has not been evaluated, benefix should not be mixed with infusion solutions or be given in a drip. please dispose of all unused solution, empty vials and used needles and syringes in an appropriate container for throwing away waste as it may hurt others if not handled properly. if you take more benefix than you should please contact your doctor immediately if you inject more benefix than your doctor recommends. if you stop taking benefix do not stop taking benefix without consulting your doctor. if you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.', 'Entity_Recognition': [{'Text': 'benefix', 'Type': 'PRODUCT_NAME', 'BeginOffset': 0, 'EndOffset': 0}, {'Text': 'this medicine', 'Type':

{'Title': '4. possible side effects', 'Section_Content': 'like all medicines, this medicine can cause side effects, although not everybody gets them. hypersensitivity/allergic reactions allergic-type hypersensitivity reactions are possible with benefix. such reactions may include swelling of the face or throat, burning and stinging at the infusion site, chills, flushing, itching, headache, hives, low blood pressure, lethargy, nausea, restlessness, fast heart rate, tightness of the chest, tingling, vomiting, wheezing). in some cases, these reactions have progressed to severe anaphylaxis. allergic reactions may occur together with the development of factor ix inhibitor (see also "warnings and precautions"). these reactions are potentially life-threatening. if allergic/anaphylactic reactions occur, stop the infusion immediately and contact your doctor or seek emergency medical care immediately. the treatment required depends on the nature and severity of side-effects (see also "warnings and precautions"). inhibitor development patients with haemophilia b may develop neutralising antibodies (inhibitors) to factor ix. if such inhibitors occur, a sign may be an increase in the amount of benefix typically required to treat a bleed and or continued bleeding after treatment. in such cases, it is recommended that a specialised haemophilia centre be contacted. your doctor may want to monitor you for inhibitor development (see "warnings and precautions"). a kidney disorder has been reported following high doses of plasma-derived factor ix to induce immune tolerance in haemophilia b patients with factor ix inhibitors and a history of allergic reactions (see also "warnings and precautions"). thrombotic events benefix may increase the risk of thrombosis (abnormal blood clots) in your body if you have risk factors for developing blood clots, including an indwelling venous catheter. there have been reports of severe blood clotting events, including life-threatening blood clots in critically ill babies, while receiving continuous-infusion benefix through a central venous catheter. cases of peripheral thrombophlebitis (pain and redness of the veins) and deep venous thrombosis (blood clots in the extremities) have also been reported; in most of these cases, benefix was administered via continuous infusion, which is not an approved method of administration. very common side effects (may affect more than 1 in 10 people) 30 headache cough fever common side effects (may affect up to 1 in 10 people) hypersensitivity/allergic reactions dizziness, altered taste phlebitis (pain and redness of veins), flushing vomiting, nausea rash, hives chest discomfort (including chest pain) infusion-site reaction (including itching and redness at the infusion site), infusion-site pain and discomfort uncommon side effects (may affect up to 1 in 100 people) development of neutralising antibodies (inhibitors) infusion site cellulitis (pain and redness of the skin) sleepiness, shaking vision impairment (including blurred vision, appearance of spots/lights) fast heart rate, low blood pressure renal infarct (interruption to the blood supply to the kidney) side effects with unknown frequency (frequency cannot be estimated from the available data) anaphylactic reaction thrombotic events (abnormal blood clots) lack of response to treatment (failure to stop or prevent bleeding episodes) reporting of side effects if you get any side effects talk to your doctor, pharmacist or nurse. this includes any possible side effect 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
