If a patient develops anticholinergic effects, what is the recommended management?

• A. Increase the antipsychotic dose
• B. Add another anticholinergic medication
• C. Reduce the dose or switch to another antipsychotic
• D. Discontinue antipsychotics abruptly without replacement

Answer: (C)

Anticholinergic effects from antipsychotics come from blocking muscarinic receptors, which leads to symptoms like dry mouth, constipation, urinary retention, blurred vision, and cognitive slowing. When these effects appear, the best management is to lower the antipsychotic exposure or switch to a different antipsychotic with less antimuscarinic activity. This tackles the root cause by reducing receptor blockade that causes the symptoms. Increasing the dose or adding another anticholinergic would worsen the problem, not help it. Stopping the antipsychotic abruptly without a plan risks relapse of psychotic symptoms and destabilization, so it’s not the right move unless there’s a specific, safer transition strategy in place. In more severe cases of anticholinergic toxicity, other treatments may be needed, but for routine cases, dose reduction or switching is the appropriate approach.
