What Does Acyclovir Cream Do?
Acyclovir cream (also sold under the brand name of Zovirax) treats cold sores. It can help reduce pain and shorten the duration of the outbreak. Acyclovir cream does not cure herpes (the virus that causes cold sores), prevent outbreaks, or prevent you from spreading the herpes virus to others. Even after using acyclovir cream, you can spread the herpes virus to others.
What Are Cold Sores?
Cold sores are usually caused by the herpes simplex virus type 1 (HSV-1). While cold sores eventually go away, there is no cure for herpes. Since you will always have the herpes virus, you may have cold sore outbreaks off and on for the rest of your life.
Cold sores usually clear up within one to three weeks without treatment and a little faster with acyclovir cream. Symptoms of cold sores include:
- Itching and tingling, usually about a day before a painful small hard spot appears and blisters erupt.
- Small fluid-filled blisters, typically around your lips and mouth. Cold sores may also appear on your cheeks, on your nose, or in your mouth.
- Oozing and crusting. Herpes is most contagious when cold sore blisters are oozing, so it is especially important to take precautions not to spread it to others during this stage of herpes.

Acyclovir Cream Dosage
Always follow your doctor’s or pharmacist’s instructions when using acyclovir cream. Typically, you will apply it 4 to 6 times a day for up to 10 days. Here is the typical way you should use acyclovir cream:
- Wash your hands and put on gloves to avoid spreading the virus to other parts of your body or to other people.
- Clean and dry the cold sore and the area around it.
- Apply a layer of cream where the cold sore has formed or seems to be forming.
- Rub the cream into your skin until it is completely absorbed.
- Leave the area uncovered. Do not use a bandage unless your doctor tells you otherwise.
- Remove your gloves and wash your hands again.
- Do not shower, bathe, swim, or do anything else that may wash the cream off your skin right after applying it.
