Generic Zovirax is a generic antiviral medication whose active ingredient is acyclovir. It treats infections caused by the Herpes Simplex Virus (HSV‑1 and HSV‑2), including cold sores, genital herpes, and shingles. Because the patent on the brand version has expired, the drug is sold at a lower cost by many online pharmacies, making it a popular choice for budget‑conscious patients.
Why Choose Generic Over Brand?
The original brand Zovirax was launched in the early 1990s and set the standard for oral antiviral therapy. Since the formulation is now off‑patent, manufacturers can produce the same molecule without paying royalty fees. The result is a price drop of 60‑80% in most markets. Clinical studies from the National Institutes of Health confirm that generic acyclovir has identical bioavailability and safety profile to the brand version.
How Acyclovir Works
Acyclovir is a nucleoside analogue that interferes with viral DNA replication. Once inside infected cells, viral thymidine kinase activates the drug, turning it into a chain‑terminating compound. This stops the herpes virus from multiplying, shortening the duration of outbreaks and reducing transmission risk. The mechanism is shared by other antiviral medications such as valacyclovir and famciclovir, but acyclovir remains the most widely prescribed due to its long‑track record and low cost.
Who Really Needs It?
- Adults experiencing frequent cold sores (≥4 per year).
- Individuals diagnosed with genital herpes seeking suppressive therapy.
- Patients with weakened immune systems who are prone to shingles.
- Anyone prescribed a short‑term course for a newly identified outbreak.
Doctors often start with a 200mg tablet taken five times daily for 7‑10days. For suppressive therapy, the dosage drops to 400mg twice daily. The exact regimen should always be confirmed by a qualified clinician.
Verifying a Safe Online Pharmacy
Not every website selling "cheap generic Zovirax" is trustworthy. Follow this checklist:
- Look for a valid FDA registration number or a seal from the National Association of Boards of Pharmacy (NABP).
- Ensure the site requires a prescription from a licensed doctor-either uploaded or generated via a telemedicine visit.
- Check that the pharmacy displays a physical address, a working customer‑service phone line, and clear privacy policies.
- Read independent reviews on forums such as Reddit’s r/Pharmacy and the Better Business Bureau.
- Confirm that the medication listing includes the drug’s strength (e.g., 200mg), dosage form, and expiration date.
If any red flag appears-like “no prescription needed” or “pay‑only” models-close the tab immediately. Counterfeit acyclovir can contain harmful fillers and won’t treat the virus.
Price Comparison: Generic Acyclovir vs. Brand Zovirax vs. Other Antivirals
| Medication | Typical Price per 200mg Tablet | Dosing Frequency | FDA Status | Common Side Effects |
|---|---|---|---|---|
| Generic Acyclovir | $0.25‑$0.40 | 5× daily (outbreak) or 2× daily (suppressive) | Approved | Nausea, headache, mild rash |
| Zovirax (brand) | $1.20‑$1.60 | Same as generic | Approved | Same as generic |
| Valacyclovir | $0.90‑$1.10 (500mg) | 1‑2× daily | Approved | Headache, dizziness, gastrointestinal upset |
| Famciclovir | $1.00‑$1.30 (250mg) | 3× daily | Approved | Fatigue, nausea, diarrhea |
As the table shows, generic acyclovir remains the most affordable option, especially for long‑term suppressive therapy. Valacyclovir offers simpler dosing but at roughly three times the cost per day.
Step‑by‑Step: Buying Cheap Generic Zovirax Online
- Get a prescription - either from your primary care doctor, a dermatologist, or a licensed telehealth provider. In most states, a virtual consult lasts 10‑15minutes and ends with a secure electronic prescription.
- Choose a vetted pharmacy - use the checklist above. Websites like Health‑NetRx, Blink Health, and Honeybee Health often meet the criteria.
- Enter the prescription details - key information includes drug name (acyclovir), strength (200mg), quantity (usually 30‑60 tablets), and dosage instructions.
- Verify pricing - compare the total cost after taxes and shipping. Some sites offer discount codes for first‑time buyers; apply them before checkout.
- Complete the purchase - use a secure payment method (credit card or PayPal). Look for “track‑and‑trace” shipping options.
- Receive and inspect - once the package arrives, check the label for the correct medication, strength, and expiration date. If anything looks off, contact the pharmacy immediately.
Following these steps reduces the chance of receiving counterfeit medication and keeps out‑of‑pocket costs low.
Potential Risks and How to Mitigate Them
Even legitimate generic drugs can cause side effects. Common issues include mild gastrointestinal upset, headache, and, rarely, kidney irritation. To stay safe:
- Stay hydrated - acyclovir is eliminated via the kidneys.
- Inform your doctor of any pre‑existing kidney disease or concurrent medications (e.g., NSAIDs).
- Do not exceed the prescribed dose; higher amounts increase the risk of neurotoxicity.
- If you notice rash, swelling, or breathing difficulties, seek medical attention right away.

Frequently Asked Questions
Is generic acyclovir as effective as brand Zovirax?
Yes. The FDA requires generics to match the brand in dosage, strength, safety, quality, performance, and intended use. Clinical studies show no difference in cure rates or side‑effect profiles.
Do I need a prescription to buy generic Zovirax online?
Legally, yes. All reputable US pharmacies require a valid prescription, either uploaded from your doctor or generated through a telehealth visit. Sites that skip this step are likely operating illegally.
How much should I expect to pay for a month's supply?
For the standard 200mg tablet taken five times daily during an outbreak, a 30‑tablet pack costs between $7.50 and $12.00 after shipping. Suppressive therapy (400mg twice daily) usually runs $15‑$20 for a 60‑tablet supply.
Can I use the same generic acyclovir for shingles?
Yes, but the dosage differs. Shingles treatment typically uses 800mg five times daily for 7‑10days. Always follow the prescribing doctor’s instructions.
What are the red flags for a counterfeit acyclovir?
Look for misspelled branding, unusually low prices (e.g., $0.05 per tablet), lack of a lot number or expiration date, and sellers that claim no prescription is needed. Also, beware of packaging that looks different from the FDA‑approved label.
How should I store generic Zovirax?
Store tablets at room temperature, away from excess heat and moisture. Keep them in the original container with the label intact to preserve potency.
