Summary
Caffeine antagonises adenosine receptors and may partly reduce benzodiazepine-induced drowsiness and anxiolysis. The effect is usually minor and not a reliable reversal of sedation.
What this interaction means in plain words
Caffeine and Chlordiazepoxide 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; Chlordiazepoxide belongs to Central Nervous System.
Why it happens
Pharmacodynamic antagonism, as caffeine's adenosine blockade opposes benzodiazepine sedative effects.
What to do
No dose change is usually needed; advise limiting large caffeine intake if anxiolytic benefit seems reduced.
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?
