Summary

Caffeine is a central nervous system stimulant that can partly offset the sedative and hypnotic effects of temazepam. This may reduce the effectiveness of the drug as a sleep aid or anxiolytic. The effect is pharmacodynamic and usually modest.

What this interaction means in plain words

Caffeine and Temazepam have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Caffeine belongs to Miscellaneous; Temazepam belongs to Central Nervous System.

Evidence level: Moderate

Why it happens

Caffeine blocks adenosine receptors and counteracts benzodiazepine-mediated GABA-A enhancement, producing functional antagonism of sedation.

What to do

Advise patients to avoid caffeinated drinks in the hours before a temazepam dose. Reassess the hypnotic dose only if sleep response is inadequate despite reduced caffeine intake.
