Acyclovir

This is not medical advice. Always consult a licensed healthcare professional before starting or changing any treatment. Information here is based on personal experiences and may not apply to everyone.

Acyclovir is an antiviral medication used to treat herpes zoster (shingles) by inhibiting viral DNA replication. It is most effective when started within 72 hours of rash onset, helping to reduce the severity and duration of the outbreak and lower the risk of complications like postherpetic neuralgia.

The typical dose for shingles is 800 mg five times daily for 7–10 days. While effective, its frequent dosing makes it less convenient than alternatives like valacyclovir. Common side effects include nausea, headache, and fatigue, and dose adjustment is needed in patients with renal impairment.

Acyclovir is a first-line antiviral option for shingles, especially when cost is a concern. It effectively reduces rash duration and complications like postherpetic neuralgia. However, it requires more frequent dosing (800 mg five times daily) compared to alternatives like valacyclovir, which may affect adherence.
