Which adverse effect is considered rare with Risperidone?

• A. Sedation
• B. Tardive dyskinesia
• C. Orthostatic hypotension
• D. Increased appetite

Answer: (B)

Risperidone is an atypical antipsychotic, and while it can cause movement disorders, the risk of tardive dyskinesia is rare compared to other common effects. Tardive dyskinesia is a late-onset, involuntary movement disorder, and with risperidone the likelihood is low, especially relative to effects you see more often. In contrast, sedation, orthostatic hypotension, and increased appetite are more frequent adverse effects due to its antihistaminic, alpha-1 blocking, and metabolic actions, respectively. So among these options, tardive dyskinesia is the rare one with risperidone.
