zoviraxWhat is Zovirax?

Zovirax (acyclovir) is an antiviral drug. It is designed to slow the growth and spread of the herpes virus, enabling the body to fight off the infection of the herpes simplex virus. Zovirax cannot cure herpes, but the makers claim it will lessen the symptoms of the infection and help prevent future outbreaks. It comes in several delivery forms including capsules and topical creams.

Zovirax is also widely used to treat infections caused by herpes viruses. Those illnesses effectively treated with Zovirax include: genital herpes, cold sores, shingles, and chicken pox.

What You Should Know

If you decide to take Zovirax, make sure you use the product for the entire length of time prescribed by your doctor. If you do not use the prescription strength version of the medication, make sure you follow the time guidelines closely. You may be familiar with taking other time sensitive drug regimens like antibiotics, the same principles apply to Zovirax even though symptoms may get better before the infection is completely treated.

As with any other topical herpes treatment, treatment with Zovirax should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).

It goes without saying, but herpes infections are contagious and you can infect other people, even while you are being treated with Zovirax. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.


Zovirax is a medication and has a number of risks associated with its use. Those risks have not been shown to be severe and should not be a specific deterrent to the treatment of herpes. You should however be aware of any allergies, especially to acyclovir or valacyclovir (Valtrex). If you are taking prescription Zovirax, make sure your doctor is aware of any of these allergies as they could lead to severe reactions to the drug itself or the dosage prescribed.

Zovirax has not been shown to be dangerous to unborn infants but mothers should be careful if they are breast feeding. Acyclovir passes into breast milk and may harm a nursing infant so you should not take Zovirax without telling your doctor if you are breast-feeding a baby.


Zovirax is a more traditional form of herpes treatment and has a long track record of effectiveness. The use of acyclovir has long been the “go-to” treatment for herpes and continues to be so because it seems to work better than other treatments.


Zovirax is a traditional and effective treatment for herpes. It’s hard to go wrong with a product that has been proven to work. You should consider the potential risks carefully and I recommend considering more natural remedies that can be just as effective without risking harm to yourself or nursing babies. The need for a prescription in most cases also makes this product harder to recommend. Trust your doctor but I would recommend looking seriously at more natural remedies in addition to the traditional herpes treatments.
