What the FDA labels say
From the Temazepam label · effective 2026-06-04
Prescribe the lowest effective dosage; avoid or minimize concomitant use of CNS depressants and other substances associated with abuse, misuse, and addiction (e.g., opioid analgesics, stimulants); and advise patients on the proper disposal of unused drug.
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.
The benzodiazepines, including temazepam, produce additive CNS-depressant effects when co-administered with other CNS depressants such as alcohol, barbiturates, antipsychotics, sedative/hypnotics, anxiolytics, antidepressants, narcotic analgesics, sedative antihistamines, anticonvulsants, and anesthetics.
Such abnormalities have also been reported to occur in association with the use of drugs with central nervous system depressant activity, including those of the benzodiazepine class.
This behavior is more likely to occur when temazepam capsules are taken with alcohol or other central nervous system depressants ( see WARNINGS ).
