Consult your doctor before using Zovirax, especially if you have kidney problems or are pregnant.
What is Zovirax?
Zovirax contains acyclovir, an antiviral medication targeting herpes simplex viruses (HSV) types 1 and 2, and varicella-zoster virus (VZV). HSV-1 usually causes oral herpes (cold sores), while HSV-2 causes genital herpes. VZV causes chickenpox and shingles.
How Zovirax Works
Acyclovir mimics a building block of viral DNA. Viruses incorporate acyclovir into their DNA, halting further replication and reducing viral load. This limits the severity and duration of outbreaks.
Available Forms and Dosages
Zovirax comes in various forms: cream for topical application to cold sores and genital herpes; tablets and capsules for oral administration to treat more severe or systemic infections; and intravenous formulations for hospital use.
- Cream: Apply thinly to affected areas several times daily.
- Oral: Follow your doctor’s prescription precisely regarding dosage and frequency.
Potential Side Effects
- Cream: Mild skin irritation at the application site.
- Oral: Nausea, headache, diarrhea, fatigue. Rarely, more serious side effects can occur.

Drug Interactions
Zovirax may interact with other medications. Inform your doctor of all medications, including over-the-counter drugs, supplements, and herbal remedies, you are currently taking.
When to See a Doctor
Seek immediate medical attention if you experience severe side effects or if your symptoms worsen despite treatment.
Potential Risks and Interactions with Other Medications
Always inform your doctor about all medications you’re taking, including over-the-counter drugs, herbal remedies, and supplements, before starting Zovirax. This allows your doctor to assess potential interactions and adjust your treatment accordingly.
Some medications may increase the risk of side effects when taken with Zovirax. For instance, concurrent use with certain nephrotoxic drugs (those harmful to the kidneys) may increase the risk of kidney problems. Probenecid, a medication used to treat gout, can also interact, potentially raising Zovirax levels in your blood.
Zovirax can interact with drugs that affect the immune system, potentially altering their efficacy or increasing the likelihood of side effects. Your doctor should closely monitor you if you are on immunosuppressants while taking Zovirax.
If you experience any unusual side effects like nausea, vomiting, diarrhea, headache, or dizziness while on Zovirax, immediately contact your doctor. This may be a sign of an interaction or an adverse reaction. Report any changes in your kidney function or blood counts as well.
This information isn’t exhaustive, and individual reactions vary. Always follow your doctor’s instructions and promptly report any concerns.
