From the Temazepam label · effective 2026-06-04
Although behaviors such as “sleep-driving” may occur with temazepam capsules alone at therapeutic doses, the use of alcohol and other CNS depressants with temazepam capsules appear to increase the risk of such behaviors, as does the use of temazepam capsules at doses exceeding the maximum recommended dose.
This behavior is more likely to occur when temazepam capsules are taken with alcohol or other central nervous system depressants ( see WARNINGS ).
