Summary
Cevimeline is a muscarinic agonist and donepezil raises acetylcholine levels, so cholinergic effects may be additive. This can cause sweating, nausea, diarrhea, bradycardia and bronchoconstriction.
What this interaction means in plain words
Cevimeline and Donepezil can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Cevimeline belongs to Miscellaneous; Donepezil belongs to Central Nervous System.
Why it happens
Additive muscarinic stimulation from direct agonism and cholinesterase inhibition.
What to do
Monitor heart rate, gastrointestinal tolerance and respiratory symptoms. Reduce the cevimeline dose if cholinergic adverse effects emerge.
