Frequently Asked Questions

Yes — these are prescription medicines, not supplements. A UK-registered prescriber reviews the medical information you give us, and a prescription is issued only where they judge the treatment to be appropriate and safe for you.

Treatment pairs a weight-loss medication that helps curb your appetite with the everyday changes that make the results last — regular activity and better nutrition. The medication gives you a foundation to build those habits on, rather than replacing them.

Once your questionnaire is submitted, a prescriber goes through your answers. If anything is unclear or missing, we'll get in touch before any decision is reached. How long this takes depends on your individual circumstances.

Every fee is shown to you upfront, before you decide whether to go ahead. Where a prescription is issued, you'll see the full treatment cost laid out clearly. Nothing is charged until you confirm that you want to continue.

No — we can't promise that, and you should be wary of anyone who does. Results differ from one person to the next. Prescription medication is one part of a wider plan that also relies on a healthy diet, staying active, and ongoing support.

Every medicine carries the possibility of side effects. With weight-management medicines, the ones reported most often affect the digestive system — nausea, vomiting or diarrhoea, for example. Before you begin, we provide full safety information along with the official patient information leaflet for your treatment.

Yes, if you're happy for us to. With your consent we'll pass relevant prescribing and monitoring details on to your GP, so your ongoing care stays joined up and safe.
