Looking for a bargain on the antiviral you need? Below is a step‑by‑step guide that lets you order generic Zovirax safely, avoid sketchy sellers, and keep the cost low.
What makes generic Zovirax a smart choice?
Generic Zovirax is a valacyclovir tablet approved for treating herpes simplex virus (HSV) infections, shingles, and genital herpes. The active ingredient, valacyclovir, is the same as the brand‑name product, so clinical effectiveness and safety are identical. The price gap comes from the lack of branding and marketing costs.
Because the molecule is identical, the dosage-usually 500mg taken twice daily for cold‑sores or once daily for shingles-remains unchanged. You get the same fast‑acting relief without the premium markup.

Price comparison snapshot
| Product | Strength | Pack Size | Price (£) | Price per Tablet (£) |
|---|---|---|---|---|
| Generic Zovirax | 500mg | 14 tablets | 9.90 | 0.71 |
| Zovirax (brand) | 500mg | 14 tablets | 13.99 | 1.00 |
| Acyclovir (generic) | 400mg | 28 tablets | 8.50 | 0.30 |

Safety, side‑effects, and who should avoid it
Valacyclovir is generally well‑tolerated. Common side‑effects include mild headache, nausea, and occasional dizziness. Severe reactions-such as rash, fever, or kidney issues-are rare but require immediate medical attention.
People with severe renal impairment, pregnant women, or those allergic to acyclovir should discuss alternatives with their doctor before ordering.
UK regulations and prescription rules
The MHRA (Medicines and Healthcare products Regulatory Agency) governs all medicines sold in the UK, online or in‑store. Under the Human Medicines Regulations 2012, any oral antiviral that requires a prescription must be dispensed only by a registered pharmacy after verifying a valid prescription.
The NHS does not cover generic Zovirax for self‑treated cold‑sores, so patients pay out‑of‑pocket. However, the NHS may subsidise larger packs for chronic genital herpes under certain clinical criteria.
Frequently Asked Questions
Can I buy generic Zovirax without a prescription?
No. UK law requires a valid prescription for any valacyclovir product, whether brand‑name or generic. Sites offering it without a script are likely illegal.
How much does a 14‑day course cost?
The average price for 14×500mg generic tablets is around £9.90, which works out to roughly £0.71 per tablet.
Is it safe to import generic Zovirax from abroad?
Importing medicines not authorised by the MHRA can be risky. Counterfeit pills may contain incorrect doses or harmful contaminants. Stick with UK‑licensed online pharmacies.
What’s the difference between valacyclovir and acyclovir?
Valacyclovir is a pro‑drug of acyclovir, meaning the body converts it to acyclovir after ingestion. This conversion boosts bioavailability, so you need fewer tablets for the same effect.
How quickly does generic Zovirax start working?
For cold‑sores, relief can begin within 24‑48hours if treatment starts at the first tingling sign. For shingles, the medication is most effective when begun within 72hours of rash onset.
By following the steps above, you can secure a legitimate, cheap supply of generic Zovirax without compromising safety. Remember: a valid prescription, a verified MHRA‑registered pharmacy, and a clear price breakdown are the three pillars of a smart purchase.

October 8, 2025 AT 17:59One must first verify that any online pharmacy displays a legitimate MHRA registration number, otherwise the site is operating outside UK law. The presence of a valid registration can be checked on the official MHRA portal, and any discrepancy should raise immediate suspicion. Moreover, a prescription is not optional; the Medicines Act strictly requires a qualified prescriber to authorize valacyclovir. Skipping this step not only violates regulations but also puts the patient at risk of receiving sub‑standard medication. Generic Zovirax, while chemically identical to the brand, must be sourced from a licensed dispenser to ensure batch consistency. Do not be fooled by flashy discounts that hide illicit supply chains. Secure HTTPS encryption on the checkout page is a baseline security measure; without it, personal data may be intercepted. The pharmacy should also publish a physical UK address and a reachable telephone number; anonymity is a red flag. A clear refund policy, preferably a 14‑day money‑back guarantee, indicates confidence in product authenticity. Prices per tablet that deviate dramatically from the £0.45‑£0.70 range warrant further investigation. Remember, a lower price does not supersede legal compliance; illegal imports can contain counterfeit active ingredients. If the site claims “no prescription needed,” it is operating illegally and should be avoided. Always retain a copy of the prescription submitted, as the pharmacy may need to reference it for future audits. Shipping should be trackable; a lack of tracking information is another warning sign. Finally, after receipt, inspect the packaging for tampering and verify that the batch number matches the one recorded by the pharmacy. Following these steps safeguards both legal standing and health outcomes.
