Harm Potential

Addiction & Dependence

Psychological

High

Quazepam is described as habit-forming and as a drug with misuse potential; boxed-warning language covers abuse, misuse, and addiction across benzodiazepines.

Physical

High

Benzodiazepine physical dependence and withdrawal are described, and quazepam should be withdrawn gradually after use beyond four weeks to avoid severe withdrawal syndrome.

Toxicity

central nervous system

Overdose may cause drowsiness, dysarthria, confusion, ataxia, coma, paradoxical disinhibition, and next-day impairment from metabolite accumulation.

respiratory

Severe overdose may lead to respiratory depression.

motor/balance

Repeated administration and active metabolite accumulation are associated with balance impairment, unstable posture, motor incoordination, and fall risk.

reproductive/lactation

Special precaution is advised in pregnancy, and quazepam and active metabolites are excreted into breast milk.

Seizure Risk

Flumazenil can provoke seizures in long-term benzodiazepine users with physical dependency, and abrupt withdrawal in animal studies caused convulsions and withdrawal-related deaths.
