Which of the following is NOT listed as an adverse effect of ropinirole?

• A. Sleep attacks
• B. Edema
• C. Headache
• D. Syncope

Answer: (C)

Ropinirole is a dopamine agonist used for Parkinson’s disease and restless legs syndrome, and the question is about which adverse effects are commonly listed for this medication. Sleep attacks are a well-recognized adverse effect of dopamine agonists, reflecting sudden episodes of sleepiness that can occur without warning. Edema can occur with these agents due to vascular and autonomic effects, and syncope can result from orthostatic changes or vasodilation associated with dopamine agonist therapy. Headache, while it can happen with many drugs, is not typically listed as a common adverse effect of ropinirole in standard references, so it’s considered not listed among the usual adverse effects. If a patient reports headaches while on ropinirole, it’s worthwhile to evaluate other potential causes, but this symptom isn’t a classic, expected adverse effect of the medication.
