Aciclovir is a medicine that fights infections caused by viruses.
For herpes infections, the typical dose is 200 mg, taken five times a day, about every 4 hours, for five days, skipping the night dose. Your doctor will tell you the exact dose.
Take the tablets with a glass of water or other liquid.
Do not take more than 1600 mg in a single day, unless your doctor tells you otherwise. Drink plenty of fluids during treatment.
Suitable for older adults. Reduce the dose and/or increase the dosing interval in severe renal impairment. (updated 4.12.2023)
