A questionnaire is the starting point

An online form gathers information quickly. A prescriber still needs enough reliable evidence to make a clinical decision. The GPhC's distance-services guidance requires proper safeguards for higher-risk medicines, and weight-management treatment counts as one. Typing in a preferred BMI should never decide whether you receive a pen.

Expect the service to explain how it checks your weight, height and relevant health information. A request for records, a consultation or extra evidence is often a sensible step. The answer may reveal a medicine interaction, a duplicate prescription or a diagnosis, and any of these changes the safest choice of treatment.

The clinical questions to expect

A good assessment covers previous weight-management treatment, diabetes, current medicines, allergies, significant digestive problems and pregnancy plans. Previous pancreatitis, episodes of dehydration, gallbladder symptoms and diabetic eye disease need particular attention. The prescriber should also ask whether a smaller appetite would make nutritional or psychological difficulties worse.

If you have used Mounjaro before, record the strength you took, the date of your last dose, the length of any gap and any side effects. An order confirmation alone may not show what you injected. A new prescriber should review any break in treatment before supplying a higher strength you used before.

Check the people and organisations

For a pharmacy in Great Britain, search the GPhC register. Match the pharmacy's name, address and registration details to the service you are using. Northern Ireland has a different pharmacy regulator. A logo on a website proves nothing until you check the official record. Prescribers hold professional registration too. Check it with the relevant regulator.

Some services combine a clinic, a separate prescriber and a dispensing pharmacy. The service should state who makes clinical decisions, who supplies the medicine, who controls your personal information and whom you contact when something goes wrong. Which regulator covers the service depends on how the service runs and where.

Check the care as well as the price

Ask how the service handles urgent side-effect questions, whether routine reviews come included and how it investigates replacements or temperature concerns. Ask about any subscription, cancellation terms, delivery charges and the evidence you would need to move to another provider. These details affect whether your care continues smoothly, as well as what you pay.

A four-dose pen gives four weekly doses. That covers 28 days of scheduled treatment, which is shorter than most calendar months. Check what a quoted monthly price includes. Talk about future dose prices and long-term affordability before you start, without assuming you will reach the highest strength.

A safe outcome can be a different recommendation

The clinician may suggest another treatment, ask for a GP assessment, delay prescribing or decide medication is unsuitable for you. A responsible consultation explains the reason and the next steps. A service that approves everyone is showing you nothing about its quality.

Avoid prescription-only medicines offered by social-media sellers or through informal resale. A box can look genuine and still tell you nothing about how the medicine was stored or whether the product is real. Safe treatment needs both a clinical assessment and a regulated supply chain. A discount code or a review score replaces neither.
