Summary
Caffeine is a stimulant and can antagonize the sedative and anxiolytic effects of clonazepam. The result is usually reduced drowsiness or reduced anxiety control rather than harm.
What this interaction means in plain words
Caffeine and Clonazepam 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; Clonazepam belongs to Central Nervous System.
Why it happens
Caffeine blocks adenosine receptors, which opposes the CNS depressant effect of benzodiazepines.
What to do
No dose adjustment is usually needed; consider limiting caffeine intake if anxiety or insomnia is poorly controlled. Do not use caffeine to counter clonazepam oversedation.
