When a painful cold sore or genital herpes flare‑up hits, the last thing you want to do is hunt for an overpriced prescription. Luckily, you can buy acyclovir online at a fraction of the retail price, without compromising safety. Below is a step‑by‑step guide to finding a reliable source for cheap generic Zovirax, plus what you need to know about dosage, side effects, and legal considerations.
What is Generic Zovirax?
Generic Zovirax is the off‑label name for acyclovir, an antiviral medication that stops the herpes simplex virus from replicating. It was first approved by the FDA in 1982 and has since become the workhorse for treating cold sores, genital herpes, and shingles.
Why Choose a Generic Over the Brand?
Brand‑name Zovirax costs anywhere between £15‑£25 per 150‑tablet pack in the UK. The same dosage in generic form typically drops to £5‑£9. The active ingredient, acyclovir, is identical, and the manufacturing standards are the same because generics must meet the same bio‑equivalence criteria as the brand.
Besides price, generics often come in larger pack sizes, giving you a better supply for recurring outbreaks.
Finding a Safe Online Pharmacy
Not every website that claims to sell cheap medication is trustworthy. Follow these checkpoints before you click “add to cart”.
- Check the licence. In the UK, a legitimate pharmacy will display a General Pharmaceutical Council (GPhC) registration number.
- Look for a qualified pharmacist. Reputable sites provide a real‑time chat or phone line with a registered pharmacist who can verify your prescription.
- Read the privacy policy. Your health data should be encrypted and never sold to third parties.
- Compare prices. Use a price‑comparison table (see below) to ensure you’re getting the best deal.
How to Get a Prescription Online
In the UK, acyclovir is prescription‑only. However, many online pharmacies offer a quick e‑consultation with a registered medical professional. The process usually looks like this:
- Fill out a short health questionnaire describing your symptoms.
- Upload any existing prescription or medical records if you have them.
- The pharmacist or doctor reviews the information and, if appropriate, issues an electronic prescription.
- The prescription is sent directly to the pharmacy’s dispensing system, and the medication ships to your door.
Some services even provide a free 30‑day trial dose for first‑time users.
Dosage & Administration
Generic Zovirax comes in tablet, suspension, and cream forms. The most common regimen for cold sores is 200mg taken five times daily for five days. For genital herpes, doctors often prescribe 400mg three times a day for 10 days during an outbreak.
Always follow the specific instructions on the prescription label. If you miss a dose, take it as soon as you remember-unless it’s almost time for the next one, then skip the missed dose.

Potential Side Effects & Interactions
Most people tolerate acyclovir well, but be aware of these occasional issues:
- Headache or dizziness
- Nausea or mild stomach upset
- Rash (stop using and contact a pharmacist if it spreads)
Serious side effects like kidney problems are rare and usually linked to high‑dose intravenous therapy, not oral tablets.
Acyclovir can interact with drugs that affect kidney function, such as NSAIDs or certain antibiotics. Always list all your current medications during the e‑consultation.
Price Comparison Table
Medication | Typical Price (UK) | Formulations | FDA/EMA Status | Typical Use |
---|---|---|---|---|
Brand Zovirax | £15‑£25 per 150 tablets | 200mg tablets, 5% cream | Approved (FDA/EMA) | Cold sores, genital herpes |
Generic Acyclovir | £5‑£9 per 150 tablets | 200mg tablets, suspension, cream | Approved (FDA/EMA) | Cold sores, genital herpes, shingles |
Valacyclovir | £12‑£18 per 30 tablets (1g) | 1g tablets | Approved (FDA/EMA) | Herpes, shingles (once‑daily dosing) |
Saving Tips Beyond the Base Price
Even after you’ve found a cheap generic, you can stretch your budget further:
- Use a prescription discount card. Many UK charities issue free cards that shave off up to 25%.
- Buy in bulk. A 300‑tablet pack often costs less per tablet than the standard 150‑tablet box.
- Check for NHS coverage. If you have a chronic condition, your GP may be able to prescribe the medication under the NHS, eliminating the cost entirely.
Red Flags: When a Deal Is Too Good to Be True
Beware of websites that promise “no prescription needed” for acyclovir. In the UK, selling prescription‑only medicines without verification is illegal and usually means the product is counterfeit. Signs of a scam include:
- Prices under £1 for a full pack
- No clear contact information or physical address
- Absence of a visible pharmacist’s registration number
If you spot any of these, move on to a better‑vetted retailer.
Next Steps: Your Quick‑Start Checklist
- Confirm you have a valid prescription or are ready for an e‑consult.
- Choose a licensed online pharmacy that displays GPhC details.
- Compare the price using the table above - aim for £5‑£9 per 150 tablets.
- Place the order and note the expected delivery window (usually 2‑3 business days).
- Read the medication guide and set a reminder for your dosing schedule.
Follow these steps, and you’ll have cheap, effective antiviral relief without any hassle.
