Zovirax Liquid is a prescription medication used to treat infections caused by the herpes simplex virus, including initial and recurrent genital herpes, as well as herpes zoster (shingles). It contains the active ingredient acyclovir, which is an antiviral drug. It works by stopping the spread of the herpes virus in the body.

Zovirax Liquid is available in a 200 mg/5mL strength and is typically taken 5 times a day for 5 to 10 days, depending on the condition being treated. In addition, in people with a weakened immune system, acyclovir can decrease the risk of the virus spreading to other parts of the body and causing serious infections.

It should be shaken well before use and measured using the provided measuring spoon or cup.
