If you clicked this, you want the cheapest legit aciclovir (the generic of Zovirax) online-fast-without getting stung by fakes, delays, or surprise fees. Here’s the short version: cream is pharmacy-sold without a prescription; tablets and suspension need a UK prescription. The best price is usually generic from a registered UK online pharmacy you can verify. The traps? Sites skipping medical checks, prices that are too good, and delivery that turns “next day” into next week. I’ll show you how to buy safely, what prices actually look like in the UK right now, and when a slightly different medicine (valaciclovir) works out better in real life.
Zovirax is the brand name; the active ingredient is aciclovir (spelled acyclovir in the US). It’s an antiviral that blocks herpes viruses from multiplying. That matters for three common problems: cold sores (HSV-1), genital herpes (HSV-1/HSV-2), and shingles (varicella-zoster).
Forms you’ll see when you shop:
If you want “cheap,” your mind goes straight to generic-good instinct. Generics must meet the same quality and bioequivalence standards as branded medicines. In daily life, that means the same effect for a lot less money in most cases.
“Aciclovir is an antiviral medicine used to treat infections caused by herpes viruses. It doesn’t cure herpes but can make outbreaks shorter and less severe.” - NHS
Quick matching guide:
One more naming thing for your searches: in the UK, you’ll see “aciclovir.” In US-based articles, it’s “acyclovir.” It’s the same drug. Search both spellings if you’re price-scouting, but buy from UK-registered pharmacies.
You’re here for a straight path: safe, quick, and good value. This is the route I use from Birmingham, and it works the same across England, Scotland, Wales, and Northern Ireland.
Shopping checklist (pin this in your head):
And because you came here for a deal: look for multibuy savings on cream if you go through a lot of it (cold sores often hit in clusters), and consider valaciclovir if you keep forgetting multiple daily aciclovir doses. Non-adherence is expensive when outbreaks keep coming back.
These are typical price ranges you’ll see at UK-registered online pharmacies right now. Prices vary by brand, supplier, and whether you’re using NHS or private routes. Use this as a sanity check before you pay.

Two savings heuristics that actually work:
How generic aciclovir compares to brand Zovirax and valaciclovir:
Ethical tip: If a website offers to buy generic Zovirax online with no questions asked, you’re not getting a bargain-you’re taking a risk. Legit sites will screen you, verify identity when needed, and provide a UK-licensed prescription process.
Medicines are safe when used as directed and risky when they’re not. Keep it boring and safe.
Common side effects (tablets): nausea, headache, dizziness, diarrhea. Less common but important: kidney stress-especially if dehydrated or if you have kidney disease. Drink fluids. If you notice confusion, severe drowsiness, reduced urine, or a rash, get medical help quickly.
Who needs a doctor’s input before using tablets: people with kidney problems, pregnant or breastfeeding, immunocompromised, older adults, and anyone taking interacting medicines (notably some HIV meds, methotrexate, tacrolimus/ciclosporin that stress kidneys, or other nephrotoxic drugs). Your online consultation or GP review should screen for these.
Counterfeit and unsafe site red flags:
Dosing basics you’ll commonly see (for orientation only-follow your prescriber’s instructions):
When to seek urgent help:
Responsible buying looks like this: you verify the pharmacy, use the right form for your problem, accept the brief clinical checks, and don’t chase “too cheap” offers. You get the effect you want-shorter, milder outbreaks-without drama.
Do I need a prescription?
Cream? No-sold at pharmacies. Tablets or suspension? Yes-UK prescription only. A registered online pharmacy can issue a private prescription after a short medical questionnaire if appropriate.
Is generic really the same as Zovirax?
Yes. Same active ingredient and strength, held to bioequivalence standards. Texture of the cream can feel slightly different between brands, but clinical effect is the same.
Can I “stockpile” tablets for future outbreaks?
Many clinicians provide a standby supply for recurrent herpes so you can start early. Don’t overbuy or use expired medicines. Keep tablets in original packaging.
Is valaciclovir worth the extra cost?
If you forget multiple daily doses or you’re on suppression, yes, often. Fewer outbreaks and easier adherence can outweigh the price difference.
How fast will an online order arrive?
Standard: 2-4 working days. Tracked 24 or next-day courier: usually next working day if you order before the cut-off. Weekends can push delivery to Monday without Saturday service.
Can I get this on the NHS online?
Many NHS GP practices allow electronic prescriptions sent to online or local pharmacies. In England, you’ll pay the prescription charge unless exempt. In Scotland, Wales, NI, it’s free.
Do I need tablets for cold sores?
Most people do fine with cream started early. Tablets can be used for severe or frequent episodes-your clinician will advise.
If you’re ready to buy, here’s a clean path for common situations.
Cold sore starting today (tingle stage), want treatment now
Recurrent genital herpes, want tablets to keep at home
Frequent outbreaks (3+ per year), want fewer flare-ups
New shingles rash, 55+, started within the last 72 hours
Order delayed or out of stock
Quick reality checks that save money and stress:
If you want to be done in five minutes: pick a UK-registered pharmacy you can verify on the GPhC register, choose generic aciclovir in the right form for your need, confirm the total cost including delivery, and complete the medical questions honestly. That’s how you get cheap, safe, and on time-without the nasty surprises.

Check the cream tube for batch numbers and the leaflet before you hand over any cash, that immediately weeds out dodgy packs and helps if you ever need a refund or replacement.
Also stick the spare tube in your bag or desk because using it at the first tingle actually makes a massive difference, and the travel-to-pharmacy time is the single most common reason people miss the treatment window.
Generic cream is fine and usually cheaper, but always verify the pharmacy so you are not left with a fake-looking tube that shipped from overseas.

Start with the regulatory check and build from there, that one habit saves time, money, and anxiety every single time.
The General Pharmaceutical Council entry for a seller is not optional to inspect, it is the minimum step and it will show the superintendent pharmacist and the business address which tells you whether the site is a proper UK outlet or an overseas dodgy depot posing as British because that trick is common and it works on people who shop fast.
Private online consultations are useful when you need meds quickly but remember that convenience has a cost and that cost should be added to the headline drug price when you compare offers so you are doing honest arithmetic and not being seduced by a low sticker price.
Prescription Prepayment Certificates are underused by people who have frequent prescriptions, and they often save more money than chasing single-item discounts, especially in England where the per-item NHS charge exists and stacks up fast.
Valaciclovir is a different beast in practice because its dosing schedule often means fewer missed doses, and fewer missed doses means fewer outbreaks which actually changes the long-run cost equation in favor of the pricier pill for a subset of people.
Shipping speed matters more than a few pounds when you are inside the 24 to 72 hour window for antivirals and that sometimes means paying for next-day tracked delivery, which is a sensible insurance policy not an indulgence.
Beware photos on sites that show generic stock images rather than clear pictures of the actual UK packaging and batch numbers because if the seller refuses to provide a photographed batch number on request, that is a red flag that they are sourcing product from non-UK channels.
For children and people who cannot swallow tablets, the suspension is an inexpensive and effective option but double-check the expiry and storage instructions because liquid formulations are more sensitive once opened.
Kidney function screening matters for tablets because aciclovir is renally excreted and dosing adjustments are common in older adults or people on nephrotoxic meds, so the clinical questionnaire in an e-consult should not be a mere formality and should capture those risk factors clearly.
Pregnant people and those planning pregnancy need bespoke advice and this is not the place to cut corners, prescribers will often opt for the safest route and the short-term cost difference is irrelevant compared with avoiding complications.
Stockpiling a reasonable standby supply is sensible for recurrent episodes but hoarding large quantities is wasteful and increases the risk of using expired or degraded medicine, so keep it modest and rotate stock.
Generic equals same active ingredient, and properly licensed generics are bioequivalent within accepted limits so efficacy is not the issue - the issue is the legitimacy of the seller and the integrity of the supply chain.
If a site says it will ship prescription tablets to you with no questions, that is not a cost advantage, that is a scam vector and you should close the tab and report the site if you can.
Finally, for shingles near the eye or any sign of systemic illness, treat it as urgent and use NHS urgent care pathways because antiviral timing plus specialist input is important and saves complications.
