Summary
Cevimeline is a muscarinic agonist and trazodone has only weak anticholinergic activity, so any pharmacodynamic opposition is likely small. Cevimeline is also metabolized by CYP2D6 and CYP3A4, and trazodone is not a significant inhibitor of either, so no meaningful change in exposure is expected.
What this interaction means in plain words
Cevimeline and Trazodone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Cevimeline belongs to Miscellaneous; Trazodone belongs to Central Nervous System.
Why it happens
