Important Information Regarding GP Prescribing of Mounjaro (Tirzepatide) for Weight Management

You may be aware of recent media announcements regarding the potential for General Practitioners to prescribe weight loss injections, specifically Mounjaro (Tirzepatide), from June 2025. While this is accurate, it is crucial to understand that the eligibility criteria for this medication will be exceptionally stringent.

National calculations indicate that approximately 220,000 patients across the UK will qualify. It is important to note that some of these patients may already be receiving alternative weight management medications.

Given the current challenges in accessing general practice services and limited resources, we kindly request your cooperation in avoiding unnecessary appointments for Mounjaro prescribing discussions if you do not meet the strict criteria. This will help us ensure that appointments remain available for patients with urgent medical needs.
