Looking for a low‑cost way to get generic Zovirax without leaving home? You’re not alone. Many people with cold sores, shingles or genital herpes need acyclovir but balk at the brand‑name price. This guide walks you through what to check, where to look, and how to stay safe while ordering the generic antiviral from a reputable online pharmacy.
What Is Generic Zovirax?
Generic Zovirax is the off‑label name for acyclovir, an antiviral medication that stops the herpes virus from replicating. The active ingredient is identical to the brand version sold as Zovirax, but manufacturers can price it lower because they don’t bear the original development costs.
Why Choose Generic Over Brand?
- Cost: Generic tablets often cost 60‑80% less than the brand.
- Effectiveness: Clinical studies show no difference in cure rates or side‑effects.
- Availability: Many online pharmacies stock generic acyclovir in 200mg and 400mg tablets.
In the UK, the MHRA (Medicines and Healthcare products Regulatory Agency) treats the generic as a fully approved medicine, provided the supplier has a valid UK marketing authorisation.
Legal Snapshot: Do You Need a Prescription?
In Britain, acyclovir is prescription‑only (POM). That means a licensed prescriber must issue a script before any pharmacy can dispense it, even online. Some sites claim “no prescription needed” - those are red flags. A legitimate online pharmacy will either ask you to upload a copy of your prescription or arrange a tele‑consultation with a qualified clinician.
How to Spot a Reputable Online Pharmacy
Follow this checklist before you click “Buy”:
- Check for a UK address and a valid MHRA registration number. You can verify it on the MHRA website.
- Look for the Pharmacy License badge. In England, it’s issued by the General Pharmaceutical Council (GPhC).
- Confirm they require a prescription or offer a free online medical review.
- Read reviews on independent forums - not just the site’s testimonial carousel.
- Check shipping policy: discreet packaging, tracking, and a clear return‑refund process.
Sites that meet all five points are usually safe bets. Examples include Chemist Direct, LloydsPharmacy.com, and Boots Online (all UK‑based).

Price Comparison: Generic vs Brand, UK vs US
Source | Product | Price (GBP) | Prescription Required |
---|---|---|---|
Boots Online | Generic acyclovir 400mg | £9.95 | Yes |
Cheaper Health | Generic acyclovir 400mg | £8.20 | Yes (upload) |
Amazon US (import) | Brand Zovirax 400mg | £22.50 (incl. duties) | Yes |
ePharmacy Canada | Generic acyclovir 400mg | £12.80 | Yes |
Even the cheapest online UK pharmacy undercuts the US brand price by more than half, and you avoid extra customs paperwork.
Shipping, Packaging, and Safety Tips
- Choose a service that offers discreet boxes - the label should read “Pharmacy Supplies” instead of the drug name.
- Track the parcel. If the tracking number stops changing after 48hours, contact customer support.
- Inspect the blister pack upon arrival. Look for the batch number, expiry date, and the MHRA logo. Any tampering is a deal‑breaker.
- Store tablets at room temperature, away from moisture. A cool, dry cabinet works fine.
Common Pitfalls and How to Avoid Them
Now that you know the safe route, here are a few mistakes people make:
- Skipping the prescription. Without a valid script, the pharmacy may refuse to ship, and you could be breaking the law.
- Buying from “discount” sites that price the medication below cost. That often means counterfeit pills.
- Ignoring the expiry date. Acyclovir loses potency after the date printed on the pack.
- Using the wrong dosage. The standard adult regimen for cold sores is 200mg five times a day for five days. For shingles, it’s 800mg five times daily for 7‑10days. Always follow your prescriber’s instructions.
By staying vigilant, you’ll get genuine medication at a fraction of the retail price.
Key Takeaways
- Generic acyclovir (generic Zovirax) is legally the same as the brand and is much cheaper.
- Only UK‑registered online pharmacies that require a prescription are safe to use.
- Check MHRA registration, pharmacy license, and shipping policies before buying.
- Price comparison shows UK sites can save you up to £15 per 30‑day supply.
- Inspect packaging, store correctly, and follow the prescribed dosage for best results.

Frequently Asked Questions
Do I really need a prescription to buy generic acyclovir online in the UK?
Yes. Acyclovir is classed as a prescription‑only medicine (POM). Reputable online pharmacies will either ask you to upload a valid script or arrange a short video consultation with a qualified doctor before they dispense it.
How can I tell if an online pharmacy is legitimate?
Look for a UK address, a visible MHRA registration number, and a GPhC pharmacy licence badge. The site should also require a prescription and provide clear contact details, shipping tracking, and a privacy policy.
Is generic acyclovir as safe as the brand Zovirax?
Absolutely. The generic contains the same 400mg or 200mg of acyclovir per tablet, meets the same quality standards, and has been shown in clinical trials to work just as well as the brand.
What’s the typical price for a 30‑day supply of generic acyclovir?
Between £8 and £12 for 30 tablets of 400mg, depending on the pharmacy and any discounts they offer. Prices under £5 usually signal a counterfeit product.
Can I get the medication shipped to an address outside the UK?
Most UK‑based online pharmacies only ship within the United Kingdom due to prescription regulations. For EU or US addresses you’ll need to use a local licensed pharmacy that can accept your UK script.
