Zovirax prescription FAQs

  • What is Zovirax used to treat?

    Zovirax is classified as an antiviral agent and is used to treat herpes simplex virus. Specifically, Zovirax is approved by the FDA to treat:

    • Genital herpes (herpes simplex 2)

    • Cold sores (herpes simplex 1)

    • Shingles (herpes zoster)

    • Chickenpox (varicella)

    • Herpes simplex encephalitis (treated with injection)

    Zovirax was approved for the treatment of herpes simplex virus in 2002. Treatment is based upon clinical outcomes and progress.

    Zovirax was approved for children 12 years and older for the use of cold sores and the acute management of chickenpox for those who have normal immune systems.

    There is currently a chickenpox vaccine available in the United States, which gives immunity up to 20 years. The FDA advises that doctors determine the dose for children under the age of 12 when using Zovirax to treat chickenpox.

  • Is Zovirax an antibiotic?

    No, Zovirax is not considered an antibiotic, it is an antiviral. Herpes is a virus and therefore treated with antiviral medication. Antibiotics are drugs used to treat bacteria not viruses. Zovirax is used with caution as it may cause acute kidney injury (kidney toxicity) if given as rapid intravenous infusion or at high doses.

  • What is the typical dosage of Zovirax?

    Zovirax is often started at 400 mg, 3 times a day, or 200 mg 5 times daily for 7-10 days. Depending on the treatment plan, doses may be taken at 400-800 mg twice daily.

    Zovirax is prescribed at a dose of 800 mg, 5 times a day, for 7 days to treat Shingles for immunocompetent patients. Chickenpox is treated with 800 mg 5 times a day for 5 to 7 days or until lesions have crusted over for immunocompetent patients.

    For maximum benefit, treatment should begin within 24 hours after the appearance of a rash. Zovirax comes in capsules, solution, suspension, and tablets. For cold sores, it is prescribed as a cream or suspension.

    Generic forms are available. Here are some common Zovirax dosage amounts and treatment regimens:

    • Capsules: 200 mg

    • Tablets: 400 mg or 800 mg

    • Suspension: 200 mg/5 mL

  • How long does it take Zovirax to work?

    When taking oral Zovirax tablets, it may take 3 days to see symptom reduction. Zovirax works best when started within 48 hours of symptom onset. It can take up to 10 days for herpes blisters to heal while taking Zovirax.

  • What are the side effects of Zovirax?

    Side effects may occur when taking Zovirax. Many medications will cause mild-to-moderate side effects but are safe to take. Talk with your doctor if you are exhibiting these side effects while taking Zovirax:

    • Malaise

    • Skin rash

    • Diarrhea

    • Nausea

    • Vomiting

    • Headache

  • What are precautions of Zovirax?

    • Breastfeeding

    • Pregnant

    • Allergic to other antiviral medications

    • On a low-sodium diet (some medications contain sodium)

    Always speak with your doctor about the potential risks and benefits when taking prescription medications.
