Summary

What this interaction means in plain words
Caffeine and Rasagiline 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; Rasagiline belongs to Central Nervous System.
Why it happens
Additive pharmacodynamic sympathomimetic and stimulant effects; MAO inhibition may modestly potentiate pressor responses.
What to do
Advise patients to keep caffeine intake moderate and to report palpitations, severe headache or marked blood pressure elevation. Check blood pressure if symptoms occur or intake is high.
