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.
