When educating a patient about sildenafil (Viagra), which adverse effect should be a priority for the patient to report to his prescriber?
- A. Flushing
- B. Diarrhea
- C. Hearing loss
- D. Dyspepsia
Correct Answer: C
Rationale: The correct answer is 'C: Hearing loss.' In rare cases, Viagra has been associated with sudden hearing loss, typically in one ear, which can be partial or complete. Any onset of hearing problems while using Viagra should be reported promptly to the prescriber. It is recommended to discontinue the medication if it is used for erectile dysfunction.
