risk of abusing delorazepam (as well as all other benzodiazepines), this must be considered when a physician prescribes delorazepam to such patients. Although all patients being treated with delorazepam should be routinely monitored for signs of use and diversion of medication, increased monitoring of patients with a history of substance and/or alcohol use is always warranted. Non-medical benzodiazepine use in patients who have them prescribed on an as-needed basis for chronic/refractory anxiety, insomnia, and intermittent muscle spasms has occurred and generally occurs very slowly, becoming evident only after months or years since the initiation of therapy. Monitoring of patients actively using delorazepam should never be discontinued even if the patients has been stable on the medication for many months or years. Caution must be used when delorazepam is administered alongside other sedative medications (ex. opiates, barbiturates, z-drugs, and phenothiazines) due to an increased risk of sedation, ataxia, and (potentially fatal) respiratory depression. Although overdoses of benzodiazepines alone rarely result in death, the combination of benzodiazepines and other sedatives (particularly other gabaminergic drugs such as barbiturates and alcohol) is far more likely to result in death. Special cautions People with renal failure on haemodialysis have a slow elimination rate and a reduced volume of distribution of the drug. Liver disease has a profound effect on the elimination rate of delorazepam, resulting in the half-life almost doubling to 395 hours, whereas healthy patients showed an elimination half-life of 204 hours on average. Caution is recommended when using delorazepam in patients with liver disease.
