Zovirax® (Brand)

ZOVIRAX (Oral Acyclovir) is used for treating genital herpes, herpes zoster, and chickenpox. ZOVIRAX reduces the pain and the number of lesions in the initial case of genital herpes, and decreases the frequency and severity of recurrent infections. In the treatment of shingles, acyclovir reduces pain, shortens the healing time, and limits the spread of virus and the formation of new lesions.

ZOVIRAX is used to treat herpes infections of the skin, mouth, mucous membranes, genital herpes, herpes zoster (shingles), and chickenpox in some individuals. ZOVIRAX does not cure herpes, but relieves the pain and may make the infection clear faster

How to take

Your medication should not be shared with others, and the prescribed dose should not be exceeded. You can take ZOVIRAX with or without food.
ZOVIRAX does not cure herpes. However, it does reduce pain and may help the sores caused by herpes to heal faster. Genital herpes is a sexually transmitted disease. To reduce the chance of infecting your partner, forgo intercourse and other sexual contact while you have sores or any other symptom.
For Genital Herpes
The usual dose is one 200-milligram capsule or 1 teaspoonful of liquid every 4 hours, 5 times daily for 10 days. If the herpes is recurrent, the usual adult dose is 400 milligrams (two 200-milligram capsules, one 400-milligram tablet or 2 teaspoonfuls) 2 times daily for up to 12 months.
If genital herpes is intermittent, the usual adult dose is one 200-milligram capsule or 1 teaspoon of liquid every 4 hours, 5 times a day for 5 days. Therapy should be started at the earliest sign or symptom.
For Herpes Zoster (Shingles)
The usual adult dose is 800 milligrams (one 800-milligram tablet or 4 teaspoonfuls of liquid) every 4 hours, 5 times daily for 7 to 10 days.
For Chickenpox:
The usual adult dose is 800 milligrams 4 times a day for 5 days.
If you have a kidney disorder, the dose will need to be adjusted by your doctor.
The usual dose for chickenpox in children 2 years of age and older is 20 milligrams per 2.2 pounds of body weight taken orally 4 times daily, for a total of 80 milligrams per 2.2 pounds, for 5 days. A child weighing more than 88 pounds should take the adult dose.
The safety and effectiveness of oral ZOVIRAX have not been established in children under 2 years of age. However, your doctor may decide that the benefits of ZOVIRAX outweigh the potential risks. The safety and effectiveness of ZOVIRAX ointment in children have not been established. ZOVIRAX cream has not been studied in children less than 12 years old.
Your doctor will start you at the low end of the dosage range, since older adults are more apt to have kidney problems or other disease, or to be taking other medications.

Side effects

The most common side effects are nausea, vomiting, diarrhea and headache. Other reported side effects include agitation, confusion, rash, anemia, and muscle pain. Hypersensitivity reactions, seizures, agitation, confusion, anemia, hepatitis, and muscle pain have also been reported.


ZOVIRAX should be used cautiously during pregnancy only if clearly needed. It is not known if this medication appears in breast milk. Consult with your doctor before breast-feeding.

Drug interactions

Cyclosporine (Sandimmune, Neoral)
Interferon (Roferon-A)
Probenecid (Benemid)
Zidovudine (Retrovir)
