A convincing website, familiar medicine name and attractive price do not establish that an online pharmacy is safe. The most useful warning signs concern who is supplying the medicine, how treatment is assessed and whether the website’s claims can be checked independently. This guide explains how to investigate concerns and what to do if you have already ordered.
Last updated: September 2026
Start with the claim the website is making
“Fake” and “unsafe” are not interchangeable. A website may impersonate a real pharmacy, sell falsified products or operate without the relevant authorisation. A registered service can also have shortcomings in assessment, communication or supply. You do not need to prove criminal activity before deciding to pause an order.
Look beyond whether a site feels trustworthy. Write down the exact web address, the dispensing pharmacy’s name and address, and any separate prescribing organisation. If you cannot identify who will supply your medicine, there is no clear organisation against which to check the claims.
Six warning signs worth investigating
1. Prescription medicines are promised with no meaningful safeguards
An offer to supply prescription-only medicines with no prescription, no appropriate assessment and no explanation of a lawful supply route is a serious warning sign. A legitimate online consultation may result in a prescription; “you do not need an existing prescription” is therefore different from “no clinical checks required”. Pharmacists can also make certain lawful supplies under specific arrangements, including some emergencies.
Be concerned if approval is guaranteed regardless of your history, or someone coaches you to change answers until you qualify. The GPhC’s patient guidance on online treatment advises honest answers and checking the professionals involved. A questionnaire is a way to collect information, not proof that a proper assessment has occurred.
2. Registration details belong to someone else
A copied registration number can look convincing. In Great Britain, check the pharmacy through the General Pharmaceutical Council; in Northern Ireland, use the Pharmaceutical Society of Northern Ireland. Follow our registration-checking guide for the register steps. Compare the identity and address, then investigate any mismatch between the registered business and the website.
If the connection remains unclear, contact the genuine pharmacy using details obtained independently. Ask whether it operates that exact domain and dispenses for the named service. A real business’s existence does not authenticate every website displaying its name. A prescribing service may be separate and needs its own relevant checks.
3. Logos and reviews replace verifiable information
A padlock indicates an encrypted connection; it does not establish clinical quality or lawful medicine supply. A UK-looking domain, flag, professional photograph or positive review cannot settle those questions either. Treat a regulator’s logo as a route to verification, rather than a certificate you can trust merely by looking at it.
The MHRA’s FakeMeds campaign explains the different checks for Great Britain and Northern Ireland. Do not apply an old internet-logo rule indiscriminately across the UK. The MHRA also provides a suspicious-seller checker. A listing is a reason to avoid proceeding; absence from a warning list is not positive approval.
4. Sales pressure overrides health questions
Take a step back if the conversation is dominated by countdown offers, unusually large quantities, guaranteed results or claims that a medicine has no risks. A low price alone does not prove a product is fake. The concern is a pattern in which the seller pushes payment while avoiding questions about suitability, supply or follow-up.
For example, if you ask who checks interactions and receive only a discount code, the important question remains unanswered. Keep the exchange and seek a service that can explain its clinical process before you commit.
5. Nobody will explain responsibility, payment or support
Check whether you can reach the dispensing pharmacy and understand whom to contact about treatment decisions. An anonymous messaging account, unexplained payment recipient or insistence on an unusual payment method should prompt further investigation. These are practical reasons to pause, not conclusive tests of medicine authenticity.
Before paying, ask what happens if the clinician declines treatment, whether consultation fees are refundable and who deals with a missing parcel. Do not send identity documents or further payments to an unverified contact simply because it says your order is waiting.
6. The supplied product raises concerns
A broken seal, unclear origin, missing information or product that differs from what was described deserves a pharmacist’s attention. Packaging can change legitimately, and a visual inspection cannot establish what a medicine contains. The MHRA’s medicine-reporting guidance covers suspected fake products and quality concerns.
Do not take a suspicious product just to see whether it works. Ask a pharmacist or your prescriber promptly how to maintain treatment safely, especially if your next dose is due. Do not abruptly stop essential prescribed treatment without obtaining advice about a safe alternative supply.
If you have already ordered
- Protect your next dose. Explain the concern to a pharmacist or prescriber and say how much trusted medicine you have left. An online complaint does not resolve an immediate treatment gap.
- Keep evidence. Save the web address, order confirmation, messages, receipt and photographs of the product and packaging. Keep the product safely away from children and do not send it elsewhere until advised.
- Report the right problem. Use the MHRA’s suspicious online seller service for suspected illegal sales. Use Yellow Card for suspected medicine side effects or product problems. Concerns about a registered pharmacy’s practice can also be raised with its pharmacy regulator.
- Address payment concerns separately. Contact your payment provider promptly if you believe you have been defrauded or disclosed payment details to an impersonator. Use its official contact route.
If you become seriously unwell, seek urgent medical help; call 999 for a life-threatening emergency. Reporting a seller or submitting a Yellow Card is not a substitute for receiving care.
A practical decision rule
If you cannot connect the website to a verifiable pharmacy, understand the assessment or get an answer about a concerning product, pause. Record exactly which question remains unresolved. This turns a vague feeling of distrust into something a pharmacist, regulator or payment provider can investigate. For routine checks before an order, use the separate online pharmacy safety checklist.

Counterfeit medicines are not only a theoretical risk. In October 2026, UK authorities seized more than 12,000 fake tirzepatide and retatrutide weight-loss pens during an operation in Birmingham, highlighting the risks of obtaining prescription medicines outside legitimate supply channels.
Service routes to consider
These are service models, not ranked providers or purchase offers. Check the responsible organisation and current terms independently.
An independently verified pharmacy
Contact a registered pharmacy through independently obtained details. It can clarify whether a website belongs to it and advise on concerns about a supplied product.
Your usual prescriber or care team
Use your existing clinical team to resolve a treatment gap or questions about whether an unfamiliar supply is safe to use.
Official reporting services
Use the MHRA for suspected illegal online sales or medicine problems, and the relevant pharmacy regulator for concerns within its remit. Reporting does not arrange replacement medicine.
Questions to ask
Service: Which registered pharmacy is responsible for this exact website and order?
Safety: Who assesses suitability, handles medicine concerns and arranges follow-up?
Fees: Who receives payment, what is included, and what happens if treatment is declined?
For continuity of treatment while an order is investigated, see repeat prescriptions and online pharmacy services.
Frequently asked questions
Does a very low price prove the medicine is fake?
No. Price is a reason to examine the offer, not a test of authenticity. Verify the supplier, assessment and source of the medicine rather than using price alone.
Is every online questionnaire unsafe?
No. Questionnaires can form part of an assessment. The issue is whether the clinician has enough reliable information and uses any additional checks needed for safe care.
Does registration guarantee that every transaction is safe?
No. It is an essential identity and regulatory check, but it does not remove the need to examine the actual service and raise concerns.
Should I report a seller even if I cannot prove a medicine is fake?
The MHRA accepts reports of suspicious online sales. Describe what you observed accurately and provide evidence; you do not have to establish the product’s composition yourself.
Resolve unexplained identity or medicine-safety concerns before proceeding with an order.
