On this episode, I breakdown trihexyphenidyl (Artane) pharmacology, adverse effects, and drug interactions.

Trihexyphenidyl is highly anticholinergic and can cause constipation, dry eyes, dry mouth, and urinary retention.

Dementia medications like donepezil can have their effects blunted by the use of trihexyphenidyl.

Trihexyphenidyl is an older anticholinergic that is rarely used for the management of EPS caused by antipsychotics.
