Which adverse effect should patients taking amiodarone watch for and report?

• A. Hearing Loss
• B. Rash
• C. Vision Changes
• D. Hair Loss

Answer: (C)

Vision changes are a key warning sign with amiodarone because this drug can cause optic neuropathy and other ocular toxicity. While many patients may have corneal deposits without symptoms, optic neuropathy can lead to progressive, potentially irreversible vision loss if not detected early. That’s why reporting any new or worsening vision—such as blurred vision, decreased sharpness, or color vision changes—is essential so the clinician can assess and adjust treatment if needed. Hearing loss is not a typical concern with amiodarone, and rash or hair loss can occur but are less urgent and not as unique a signal for this medication. In short, new or changing vision is the most important adverse effect for patients on amiodarone to report promptly.
