Correct answer: Crefer for antiviral treatment because he is over 50 years and within 72 hours of rash onset

Oral antiviral treatment is considered for shingles in older adults and is most effective when started within 72 hours of rash onset. Age over 50 increases the risk of prolonged pain and complications. Topical aciclovir is not appropriate for shingles. Antibiotics are reserved for secondary bacterial infection rather than uncomplicated herpes zoster.
