This guide provides general information about access and is not a substitute for an individual clinical assessment. Do not start, stop, switch, or change a GLP-1 medicine based solely on this article.
In the UK, a GLP-1 medicine is prescription-only. Access can look different depending on why it is being considered, whether care is through the NHS or privately, and where you live. An online eligibility checker or another person’s experience cannot establish what is appropriate for you. Start with a qualified healthcare professional who can assess your health and explain the current pathway.
Prepare the information a clinician will need
Bring a current list of medicines, relevant diagnoses, previous weight-management support, and any treatment records you already have. Include information about symptoms, allergies, pregnancy plans where relevant, and other care you receive. If you have used a GLP-1 medicine before, record the exact product, dates, what happened, and who prescribed it. This is preparation for a clinical assessment, not a way to self-decide eligibility.
NHS access in England
For weight management, NHS England describes specific pathways for medicines such as semaglutide and tirzepatide. Semaglutide for weight management is provided through specialist weight-management services, while tirzepatide is being introduced in stages with access based on clinical need and local delivery arrangements. Check with your GP practice or local integrated care board about the current route for an assessment; arrangements and eligibility can change.
Private care needs the same care
A private prescription still requires an appropriate clinical assessment. NHS guidance advises people using a private prescription for semaglutide to obtain it from a registered pharmacy, and the MHRA warns against unsafe or unauthorised products. Check who is prescribing, how you can contact them for clinical questions, where the medicine will be dispensed, and whether follow-up is available before committing to treatment.
Keep the records after the appointment
Keep the consultation summary, prescription details, patient leaflet, dispensing information and contact details for the prescriber and pharmacy. These records support continuity of care, especially if your circumstances, location or prescriber change. For decisions about starting, continuing, switching or stopping a GLP-1 medicine, follow the official patient information and the advice of the clinician responsible for your care.
Access routes and eligibility can change and may differ across the UK. Verify the current route with the relevant NHS service or a regulated private provider, and keep all treatment decisions with a qualified prescriber.
