Which management approach would most directly reduce anticholinergic side effects without adding new medications?

• A. Reduce the dose or switch to another antipsychotic
• B. Increase the dose
• C. Add a second anticholinergic
• D. Discontinue treatment without replacement

Answer: (A)

Anticholinergic side effects come from blocking muscarinic receptors, and the extent of this blockade tends to increase with higher drug exposure. The most direct way to lessen those effects without adding any new medications is to reduce the dose or switch to an antipsychotic with less antimuscarinic activity. Lowering the dose reduces receptor blockade, which lowers side effects while aiming to preserve therapeutic benefit. Increasing the dose would likely worsen the anticholinergic symptoms, and adding a second anticholinergic would compound the burden. Discontinuing treatment removes the medication’s benefits and isn’t a targeted way to manage side effects.
