Generic Name: acyclovir (ay-SYE-kloe-vir)
Brand Name: Zovirax
Zovirax cream is used for:
Treating cold sores on the face or lips that are caused by the herpes virus. It may also be used for other conditions as determined by your doctor.
Zovirax cream is an antiviral. It works by stopping viral replication. However, Zovirax cream does not eliminate the herpes virus, it is not a cure, and it does not prevent transmission to others.
Do NOT use Zovirax cream if:
- you are allergic to any ingredient in Zovirax cream or valacyclovir
Contact your doctor or health care provider right away if any of these apply to you.
Before using Zovirax cream:
Some medical conditions may interact with Zovirax cream. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have a weak immune system or you get sick easily
Some MEDICINES MAY INTERACT with Zovirax cream. Because little, if any, of Zovirax cream is absorbed into the blood, the risk of it interacting with another medicine is low.
Ask your health care provider if Zovirax cream may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use Zovirax cream:
Use Zovirax cream as directed by your doctor. Check the label on the medicine for exact dosing instructions.

- Wash and completely dry the affected area. Apply the medicine only to the affected area and not to the surrounding skin. Gently rub the medicine in until it disappears. Wash your hands after using Zovirax cream.
- Do not rub the cold sore. Rubbing the cold sore may make it worse. It may also cause the cold sore to spread to other areas around your mouth.
- To clear up your infection completely, use Zovirax cream for the full course of treatment. Keep using it even if you feel better in a few days.
- For best results, use Zovirax cream at the first sign of a cold sore (tingling, redness, itching, or bump).
- If you miss a dose of Zovirax cream, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use Zovirax cream.
