Generic Zovirax is a generic antiviral medication that contains the active ingredient acyclovir. It treats infections caused by the herpes simplex virus (HSV), including cold sores and genital herpes. Because it’s off‑patent, the generic version is usually far cheaper than the brand name Zovirax.
The brand Zovirax is marketed by GlaxoSmithKline and was one of the first acyclovir products approved by the FDA in 1995. The generic version uses the same chemical composition, dosage forms, and therapeutic effect, but it’s manufactured by a range of approved pharmaceutical companies, which drives the price down.
But the low price comes with a responsibility: you need a reputable source. Not all websites selling “cheap acyclovir” are legitimate.
Look for these red flags and green lights:
Medication | Typical Price (30days) | Dosage Frequency | FDA Status |
---|---|---|---|
Generic Zovirax (acyclovir 400mg) | $12‑$18 | 5times/day | FDA‑approved generic |
Brand Zovirax (acyclovir 400mg) | $55‑$70 | 5times/day | FDA‑approved brand |
Valacyclovir (generic 500mg) | $30‑$45 | 3times/day | FDA‑approved generic |
Famciclovir (generic 250mg) | $28‑$40 | 3times/day | FDA‑approved generic |
As the table shows, generic Zovirax is the most affordable option for daily dosing, though newer antivirals may require fewer pills.
Most reputable sites will ship within 2‑5business days using a discreet package.
Now that you know how to buy cheap generic Zovirax safely, you may also want to read about:
Yes. In the United States the FDA requires a valid prescription for acyclovir, whether you buy the brand or generic version. Most reputable online pharmacies will ask you to upload a scanned prescription or verify it through a tele‑health service.
Absolutely. Generic acyclovir must meet the same FDA standards for purity, dosage, and bioavailability as the brand. Clinical studies show no difference in therapeutic outcome.
A typical 30‑day supply of generic Zovirax (400mg tablets) costs between $12 and $18 when purchased from a licensed online pharmacy. Prices can vary based on dosage and shipping.
Acyclovir is classified as pregnancy category B, meaning animal studies have not shown risk, but there are limited controlled human studies. Always discuss with your obstetrician before starting any medication.
Do not open the package. Contact the pharmacy’s customer service immediately and request verification. If the pharmacy cannot provide proof of authenticity, report the incident to the FDA’s MedWatch program.
