When you’re hunting for cheap generic Zovirax, you need a clear path that avoids scams, guarantees the right dosage, and lands you a fair price. Below is a step‑by‑step guide that covers everything from picking a reputable online pharmacy to checking your prescription, so you can order with confidence.
Key Takeaways
- Generic Acyclovir is the active ingredient in Zovirax and costs 60‑80% less than the brand.
- Only U.S. pharmacies certified by the FDA or a recognized pharmacy board should be used.
- Expect a 30‑day supply of 400mg tablets for about $8‑$12, and a 5‑g cream tube for $6‑$9.
- Look for TLS/SSL encryption (https://), a visible pharmacy license number, and clear return policies.
- Keep a copy of your prescription handy; most sites require a digital upload before shipping.
Understanding Generic Zovirax (Acyclovir)
Generic Acyclovir is a synthetic antiviral that works the same way as the brand‑name drug Zovirax. It blocks the DNA replication of herpes simplex viruses, cutting down outbreak duration and severity. The FDA approved the first generic version in 1998, and since then dozens of manufacturers have produced tablets, capsules, and topical creams that meet the same strict quality standards.
Because the molecular structure is identical, the clinical effectiveness, dosage, and side‑effect profile mirror the brand. The main advantage is price. A typical 30‑day supply of 400mg tablets can be purchased for under $10, compared with $30‑$40 for the brand.
How to Spot a Legitimate Online Pharmacy
The internet is littered with sites that sell counterfeit or sub‑potent medication. Use the following checklist to verify legitimacy:
- Check for a pharmacy license number. FDA requires accredited U.S. pharmacies to display a license issued by a state board.
- Confirm the site uses HTTPS encryption - look for the padlock icon in the address bar.
- Read the privacy policy and see how they handle your personal health information.
- Look for a board‑certified pharmacist available for live chat or phone.
- Verify shipping details - reputable pharmacies ship from licensed distribution centers, not from “warehouse” addresses in unknown countries.
Websites such as HealthWarehouse, PharmacyChecker, and Amazon Pharmacy regularly pass these checks and have been praised by the National Association of Boards of Pharmacy (NABP).

Step‑by‑Step Ordering Guide
- Get a valid prescription. Even if you’ve used Zovirax before, a current prescription is required by law for any online purchase.
- Choose a certified pharmacy. Use the checklist above; copy the pharmacy’s license number and verify it on the state board’s website.
- Upload or submit your prescription. Most platforms accept a clear photo or PDF. Some, like Amazon Pharmacy, let you schedule a brief telehealth visit.
- Select the correct dosage. For genital herpes, the typical regimen is 400mg five times daily for 5‑10 days. For cold sores, 200mg five times daily for 4‑5 days is common. Make sure the product you pick matches the prescribed strength.
- Add shipping details. Confirm delivery times (usually 2‑5 business days) and whether a signature is required.
- Review the total cost. Include medication price, shipping, and any applicable tax.
- Place the order. You’ll receive an order confirmation email with a tracking number.
- Inspect the package. Verify the labeling, expiration date, and that the tablet count matches your order. If anything looks off, contact the pharmacy immediately.

Safety Tips & Red Flags
Even when you follow the steps above, stay vigilant. Here are common warning signs of counterfeit or unsafe medication:
- Price dramatically lower than the market average (e.g., $2 for a 30‑day supply).
- Missing or blurry lot number and expiration date on the label.
- Packaging that differs from the FDA‑approved design - colors, fonts, or logos that look off.
- Pharmacy refuses to provide a pharmacist’s contact information or a physical address.
- Payment methods limited to cryptocurrency without any credit‑card or PayPal option.
If you encounter any of these, discard the medication and report the site to the FDA’s MedWatch program.

U.S. law requires a valid prescription for any oral or topical antiviral. Reputable online pharmacies will ask you to upload a copy or verify via telehealth before processing the order.
How long does shipping usually take?
Standard shipping is 2‑5 business days for U.S. pharmacies. Many sites offer free expedited shipping for orders over $30.

Absolutely. The 200mg tablet or 5% cream formulation is standard for oral herpes (cold sores). Follow your doctor's dosing schedule for best results.
By sticking to these guidelines, you’ll save money without sacrificing safety. Remember, the cheapest option isn’t always the best-focus on legitimacy, proper dosage, and clear pharmacy credentials.
First off, double‑check that the pharmacy displays a valid state license number, because that’s the cornerstone of legitimacy; also verify the HTTPS lock icon appears in the address bar, which indicates encrypted connections; finally, keep a screenshot of the prescription upload confirmation for your records, just in case any dispute arises later.
