Important Safety Information
Do not use ZOVIRAX Cream if you are allergic to ZOVIRAX Cream or any of its ingredients. ZOVIRAX Cream is most effective when used early, at the start of a cold sore. For best results, apply the cream at the first sign of a cold sore (such as tingling, redness, bump, or itch).
Use ZOVIRAX Cream only on your affected skin. Do not swallow ZOVIRAX Cream or apply it to the eyes, inside the mouth or nose, or on the genitals. Do not apply other topical products to the affected area while using ZOVIRAX Cream.
Before you start using ZOVIRAX Cream, tell your healthcare provider about any medications you are taking and any medical conditions you have, including if you become sick very easily (have a weak immune system), are pregnant, planning to become pregnant, or are breast feeding. You should not breastfeed if you have a cold sore near or on your breast.
The most common skin-related side effects of ZOVIRAX Cream are dry or cracked lips, flakiness or dryness of skin, a burning or stinging feeling, or itching of the skin.
You are encouraged to report side effects to the FDA. Visit or call 1-800-FDA-1088.
