Alternative Names: Famvir

Famciclovir is an oral antiviral medication used to treat herpes zoster (shingles) by inhibiting viral replication. It is most effective when started within 72 hours of rash onset, helping to shorten symptom duration and reduce the risk of postherpetic neuralgia.

The typical dose is 500 mg three times daily for 7 days. It offers a more convenient dosing schedule than acyclovir and is similar in effectiveness to valacyclovir. Common side effects include headache, nausea, and dizziness, and dose adjustment is needed for renal impairment.

Famciclovir is comparable to valacyclovir in effectiveness for treating shingles, helping to reduce rash duration and the risk of postherpetic neuralgia. It may have a slightly better side effect profile, with fewer reports of gastrointestinal symptoms. However, valacyclovir is often preferred due to better insurance coverage and simpler dosing, making it more widely used in clinical practice.
