The GPhC added weight-management medicines to its list of high-risk medicines requiring extra safeguards. For those medicines, a prescriber cannot base the decision on an online questionnaire alone. They must independently verify what you tell them — through timely two-way communication, by accessing your clinical records, or by contacting your GP or regular prescriber.
Specifically for weight management, the prescriber has to independently verify your weight, height and/or BMI.
What You Should Expect
Verification, not just a form
Some way of confirming your measurements rather than accepting typed numbers. A photo of yourself on scales, a video call, a pharmacy measurement, or contact with your GP. If the entire process is a form with no verification step, that is below standard.
A real way to reach a prescriber
Two-way communication, so you can ask questions and they can ask follow-ups. Not a generic support inbox — a route to the person making the clinical decision.
Questions that go beyond BMI
A proper assessment covers medical history, current medicines, mental health including eating disorder history, pregnancy plans and contraception, and previous weight-loss treatment. If you take tirzepatide and use an oral contraceptive, the contraception question is not optional — MHRA guidance says a non-oral method is needed.
Your GP in the loop
Good services ask for consent to inform your GP. There is guidance covering what should happen when someone has no regular prescriber or declines consent — but the default expectation is joined-up care.
Follow-up built in
These medicines are escalated over months. Review at dose changes should be part of the service, not an extra.
Warning Signs
- Approval within minutes with no verification of anything
- No named prescriber, or no way to contact one
- A questionnaire that visibly steers you towards the qualifying answers
- Pressure to buy a longer plan at the point of sale
- No mention of contraception, pregnancy or eating disorder history
- Advertising that names the medicine — which is not permitted for prescription-only medicines
Check the Registration First
Before comparing anything on price, confirm the pharmacy is UK-registered. The register is public and searchable, and a legitimate site names its pharmacy and registration number. A green cross logo on a website is an image file, not a credential.
Why the Regulator Acted
The GPhC's own inspections and investigations found too many cases of medicines being supplied inappropriately online. A later analysis of inspections of online pharmacies prescribing GLP-1 medicines identified prescribing to people who did not meet eligibility criteria, absent clinical assessment, and supply with no prescriber interaction at all.
These are not hypothetical failure modes. They are what inspectors found.
The Trade-off Worth Naming
Thorough assessment takes time and costs money, and a provider doing it properly may be neither the fastest nor the cheapest. That is the trade-off. Knowing what the standard is lets you decide deliberately how much of it you are giving up — rather than discovering later that the cheap option was cheap because it skipped the part designed to keep you safe.
