Summary

Combining zolpidem with the benzodiazepine quazepam adds sedative-hypnotic effects, raising the risk of excessive sedation, falls, amnesia and respiratory depression. Quazepam has long-acting active metabolites, so effects can persist into the next day.

What this interaction means in plain words

Quazepam and Zolpidem can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Evidence level: High

Why it happens

Additive pharmacodynamic CNS depression from two positive GABA-A receptor modulators.

What to do

Avoid using two hypnotics together; if unavoidable, use the lowest doses for the shortest time and monitor for sedation and respiratory depression.
