What is Generic Zovirax?
Generic Zovirax is a bioequivalent version of the brand antiviral Zovirax (acyclovir) that treats infections caused by the herpes simplex virus and varicella‑zoster virus. It comes in tablet, topical cream, and injectable forms, with a standard adult dose of 200mg three to five times daily for cold sores, or 400mg five times daily for more severe infections.
Why People Look for Cheap Generic Zovirax
Herpes outbreaks are common - the World Health Organization estimates that over 67% of the global population carries HSV‑1. Because the medication is taken repeatedly during flare‑ups, cost adds up quickly. Generic versions typically cost 30‑60% less than the brand, making them a go‑to for budget‑conscious patients.
How to Buy Generic Zovirax Online Safely
Buying medication over the internet feels risky, but a systematic approach can keep you protected.
- Verify the pharmacy’s licensing. In Australia, a legitimate online pharmacy displays an AUSTL (Therapeutic Goods Administration) registration number. Look for a clear privacy policy and a physical address.
- Check the FDA U.S. Food and Drug Administration or equivalent regulator’s list of approved online sellers if you’re ordering from abroad.
- Confirm Bioequivalence the scientific demonstration that the generic works the same way as the brand. Reputable sites will link to the manufacturer’s bioequivalence study or a regulatory approval notice.
- Read customer reviews, but focus on those mentioning packaging, expiration dates, and consistency of the product.
- Use a secure payment gateway (credit card or PayPal) that offers fraud protection.
- Ask for a pharmacist consultation if the site offers a chat feature. A qualified pharmacist can confirm dosage and whether a prescription is needed for your state.
Follow these steps and you’ll have a high chance of getting the right medicine without a surprise bill.
Legal and Prescription Requirements
In most countries, acyclovir the active ingredient in generic Zovirax is prescription‑only. However, some jurisdictions allow a limited over‑the‑counter supply for minor cold‑sores. Always check your local health authority’s rules before placing an order.
If a prescription is required, you have two options:
- Telemedicine consultation. Many online pharmacies partner with doctors who can issue a digital prescription after a brief video visit.
- Upload an existing prescription. Most reputable sites let you upload a scanned copy or photo of a paper prescription.

Comparing Generic Zovirax to Brand and Other Antivirals
Below is a quick look at how generic Zovirax stacks up against its brand counterpart and two popular alternatives.
Medication | Form | Typical Price (AU$/unit) | Prescription Needed |
---|---|---|---|
Generic Zovirax (acyclovir) | 200mg tablet, 5% cream | 0.35 (tablet), 1.20 (cream) | Yes |
Brand Zovirax | 200mg tablet, 5% cream | 0.80 (tablet), 2.50 (cream) | Yes |
Valacyclovir (Valtrex) | 500mg tablet | 1.10 | Yes |
Famciclovir (Famvir) | 250mg tablet | 1.30 | Yes |
Notice that generic Zovirax is roughly half the price of the brand and cheaper than the newer antivirals, making it the most cost‑effective choice for most users.
Dosage, Administration, and What to Expect
For most adult cold‑sore episodes, the standard regimen is 200mg taken five times a day for five days. For genital herpes outbreaks, the dose often doubles to 400mg five times daily, again for five to ten days. The topical cream is applied five times daily to the lesion. Always follow the prescribing doctor’s instructions.
Peak blood levels occur within one to two hours after oral intake, giving quick relief. Most patients notice a reduction in lesion size within 24‑48hours.
Managing Side Effects and Interactions
Generic Zovirax is generally well‑tolerated. Common side effects (<5% incidence) include mild headache, nausea, and occasional dizziness. Rarely, patients report renal function changes, especially when combined with NSAIDs.
Key interaction alerts:
- Probenecid: can increase acyclovir plasma levels, raising toxicity risk.
- Kidney‑impairing drugs: monitor renal function if you’re on diuretics or certain antihypertensives.
If you experience severe rash, difficulty breathing, or swelling, seek medical help immediately - these could signal an allergic reaction.

Frequently Asked Questions
Is generic Zovirax as effective as the brand?
Yes. Regulatory agencies require that generic drugs demonstrate bioequivalence - meaning the same rate and extent of absorption as the brand. Clinical studies show no measurable difference in healing time for cold‑sores or genital herpes.
Can I buy generic Zovirax without a prescription in Australia?
Generally no. Acyclovir is listed as prescription‑only. Some states allow a limited over‑the‑counter purchase for minor cold‑sores, but most reputable online pharmacies will ask for a valid prescription.
How much should I expect to pay for a month’s supply?
A typical regimen uses 200mg tablets, 5days per episode. At AU$0.35 per tablet, a full course costs about AU$17. If you treat multiple flare‑ups, multiply accordingly. Shipping is usually AU$5‑10 for standard delivery.
What are the signs of a counterfeit Zovirax?
Look for misspelled brand names, unusually low prices, lack of batch numbers, or packaging that differs from the official TGA‑approved design. If the pills dissolve too quickly or have an odd odor, discard them and report the seller.
Can I use generic Zovirax while pregnant?
Acyclovir is classified as Category B by the Australian Medicines Handbook, meaning animal studies show no risk and there are no well‑controlled human studies. Consult your obstetrician before starting any antiviral during pregnancy.
