Flurazepam potentiates other CNS depressants such as alcohol, barbiturates, sedative antidepressants, antihistamines and antipsychotic drugs. Cimetidine moderately prolongs the already long half-life of the active metabolite desalkyl flurazepam. Antacids may delay the absorption of benzodiazepines.
Dizziness, drowsiness, light-headedness, staggering, ataxia have occurred, particularly in elderly or debilitated persons. Severe sedation, lethargy, disorientation and coma have been reported.
Pregnancy category-C. Flurazepam is contraindicated in pregnant women. Lactating mothers should avoid it.
Since the risk of the development of oversedation, dizziness, confusion or ataxia increases substantially with larger doses in elderly and debilitated patients, it is recommended that in such patients the dosage should be limited to 15 mg. The usual precautions are indicated for severely depressed patients or those in whom there is any evidence of latent depression; particularly the recognition that suicidal tendencies may be present and protective measures may be necessary. The usual precautions should be observed in patients with chronic pulmonary insufficiency.
Flurazepam overdosage includes somnolence, confusion and coma. Respiration, pulse and blood pressure should be monitored as in all cases of drug overdosage. General supportive measures should be employed, along with immediate gastric lavage.
