Phenazepam is used in the treatment of neurological disorders such as epilepsy, alcohol withdrawal syndrome and insomnia. It can be used as a premedication before surgery as it augments the effects of anesthetics and reduces anxiety. Benzodiazepines require special precaution if used in the elderly, during pregnancy, in children, alcohol or drug-dependent individuals and individuals with comorbid psychiatric disorders. Phenazepam should not be taken with alcohol or any other CNS depressants. Phenazepam should not be used therapeutically for periods of longer than one month including tapering on and off the drug as recommended for any benzodiazepine in the British national formulary. Some patients may require longer term treatment. Phenazepam may be measured in blood or plasma by chromatographic methods.
