A 50-year-old male with Bipolar Disorder complains of dry mouth and constipation. His medications include lithium and olanzapine. What could be causing his symptoms?
Both lithium and olanzapine, an atypical antipsychotic, can cause anticholinergic side effects, including dry mouth and constipation. Management includes advising the patient to drink ample fluids, maintain good oral hygiene, and use over-the-counter remedies for dry mouth. For constipation, increased dietary fiber, regular exercise, and potentially the use of laxatives are recommended.
