Zovirax® is used to treat herpes infections of the skin, lip, and genitals; herpes zoster (shingles); and chickenpox. It does not cure herpes but decreases pain and itching and promotes healing. Topical Zovirax® does not prevent the recurrence of sores but may decrease pain and itching if applied when the earliest symptoms first appear. Oral Zovirax® decreases the frequency and severity of recurrent sores, but it is used only by people with severe herpes infections because of possible adverse effects.
Treatment with Zovirax® topical should be started as soon as possible after the first appearance of symptoms (e.g. tingling, burning, blisters). Wash your hands before and after applying Zovirax® topical. Wear a glove or a finger cot or use an applicator (e.g. cotton swab) when applying Zovirax® topical to avoid spreading the virus to other body parts and to other people. Apply enough ointment to cover the lesion(s) completely. Zovirax® topical is usually applied every 3 hours, six times a day for seven days.
