Generic Zovirax is a generic version of the antiviral acyclovir, used to treat herpes‑related infections such as cold sores, genital herpes, and shingles.
Why Choose Generic Over Brand‑Name Zovirax?
Generic Zovirax contains the same active ingredient, dosage strength, and therapeutic effect as the brand‑name product, but it typically costs 60‑80% less. Health regulators in the UK, the US and the EU require rigorous bioequivalence testing, so you get identical virus‑blocking power without the premium price tag.
Understanding the Core Molecule: Acyclovir
Acyclovir is a nucleoside analogue that interferes with viral DNA replication. It works best when started early in an outbreak, shortening symptoms by up to two days. Typical daily doses range from 200mg for mild oral outbreaks to 800mg four times a day for severe cases.
How to Spot a Trustworthy Online Pharmacy
Not every website that sells cheap medication is legitimate. Follow these checkpoints:
- Look for a valid pharmacy licence number displayed on the site. In the UK this is issued by the General Pharmaceutical Council (GPhC).
- Check that the site requires a Prescription Requirement for medicines that need one, such as acyclovir tablets.
- Confirm the pharmacy is registered with the FDA (or its EU counterpart) and that the website URL ends with a secure ".co.uk" or ".org" domain.
- Read independent reviews and verify that the pharmacy offers a clear return policy and customer‑service contact.

Step‑by‑Step: Ordering Generic Zovirax Safely
- Confirm the supplier meets the checkpoints listed above.
- Upload a valid prescription (if required). Most UK sites accept a digital scan or photograph via a secure portal.
- Select the desired dosage form - Dosage Form - such as 200mg tablets, 5% cream, or 5% ointment.
- Add the product to the cart and review the total cost, including shipping.
- Enter a UK delivery address; many pharmacies also offer discreet packaging.
- Complete payment using a secure method (credit card, PayPal, or NHS‑approved e‑prescription billing).
- Track the shipment via the confirmation email; most reputable sites provide a tracking number within 24hours.

Therapeutic Uses: From Shingles to Cold Sores
Generic Zovirax treats three main conditions:
- Cold sores (herpes labialis) - apply the 5% cream five times a day at the first sign of tingling.
- Genital herpes (HSV‑2) - oral tablets 200mg twice daily for five days during an outbreak.
- Shingles (herpes zoster) - high‑dose tablets (800mg) five times daily for ten days, often prescribed alongside pain‑relief medication.
Early treatment shortens healing time and reduces the risk of complications, especially in older adults. The NHS recommends starting antiviral therapy within 72hours of rash onset.
Legal and Safety Considerations
In the UK, acyclovir tablets are prescription‑only medicines (POM). Purchasing them without a prescription is illegal and poses health risks. Counterfeit products may contain incorrect dosages or harmful substances.
Always verify that the FDA or European Medicines Agency (EMA) has approved the generic version. Approved generics must meet strict quality standards, including Good Manufacturing Practice (GMP) compliance.
Saving Money Without Compromising Quality
The biggest cost driver for antiviral therapy is the prescription fee. If you qualify for the NHS Prescription Prepayment Certificate (PPC), you can cap the annual cost at £108 (2025 rate). Some online pharmacies also accept PPC numbers, letting you bypass per‑item fees.
Look for bulk‑buy discounts - a 90‑tablet pack often costs less per tablet than a 30‑tablet pack. However, only order amounts you’ll realistically use within six months to avoid waste.
Putting It All Together: Quick Checklist Before You Click ‘Buy’
- Is the site a licensed Online Pharmacy with a visible GPhC number?

- Are the price, shipping cost, and safety rating competitive compared with the table above?
- Is the Dosage Form appropriate for your condition?
- Do you have a payment method that guarantees a secure transaction?
Following these steps lets you snag cheap generic Zovirax confidently, without risking counterfeit meds or hidden fees.
Frequently Asked Questions
Do I need a prescription to buy generic Zovirax online in the UK?
Yes. Acyclovir tablets are classified as prescription‑only medicines. Reputable online pharmacies will ask you to upload a valid prescription or arrange a tele‑consultation with a licensed clinician.
Is generic Zovirax as effective as the brand name?
Absolutely. Regulators require generic products to demonstrate bio‑equivalence, meaning the drug reaches the same concentration in the bloodstream as the brand version. Clinical outcomes are identical when taken as directed.
How fast should I start treatment after a herpes outbreak?
Start within 72hours of the first tingling or rash. Early dosing shortens the episode and reduces viral shedding, which lowers the chance of passing the infection to a partner.
Can I get free shipping on cheap generic Zovirax?
Many UK‑based online pharmacies offer free standard delivery for orders over £20 or for registered NHS users. Check the shipping policy before checkout.
Is it safe to buy from overseas pharmacies?
Only if the overseas pharmacy is accredited by the EU Medicines Agency or the US FDA and can provide a valid prescription. Otherwise, you risk counterfeit medication that may contain the wrong dose or harmful fillers.
What side effects should I watch for?
Common side effects include mild nausea, headache, and dizziness. Rarely, kidney problems can occur, especially with high‑dose regimens. If you notice severe rash, swelling, or difficulty breathing, seek medical help immediately.
Can I use the cream on my genitals?
The 5% acyclovir cream is formulated for oral lesions only. For genital herpes, oral tablets are the recommended form. Using the cream on mucous membranes can cause irritation.
How long does a typical shipment take?
Standard UK delivery usually arrives within 2-4 business days after the prescription is verified. Express options are available for an additional fee.
