Correct answer: E — Aciclovir 800 mg five times daily for 7 days

The best answer is “Aciclovir 800 mg five times daily for 7 days”. Older adults presenting within 72 hours generally benefit from an oral antiviral; aciclovir 800 mg five times daily for 7 days is a standard regimen. Dose adjustment is needed in renal impairment, and eye or neurological involvement changes the urgency and referral pathway; topical antiviral or corticosteroid monotherapy is inadequate.
