Summary
Caffeine can reduce the sedative and hypnotic effect of triazolam, which may lead to poorer sleep induction. Triazolam is short-acting and used for insomnia, so evening caffeine is particularly relevant.
What this interaction means in plain words
Caffeine and Triazolam have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Caffeine antagonizes adenosine receptors, functionally opposing GABA-A-mediated benzodiazepine sedation.
What to do
Counsel patients to avoid caffeine in the afternoon and evening when taking triazolam. Do not escalate the benzodiazepine dose to overcome caffeine's effect.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
