Description:
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.
