Mounjaro (tirzepatide), a promising medication for managing Type 2 diabetes and aiding in weight loss, has seen some significant regulatory updates and changes in availability within the UK. As of 2024, understanding the pathways to access this medication, whether through the National Health Service (NHS) or private healthcare providers, is crucial for patients and healthcare providers alike.
NHS Approval Status
As of October 2024, the National Institute for Health and Care Excellence (NICE) announced that a consultation will begin following an application from NHS England regarding how a phased launch of Mounjaro as a medication for weight loss could be manage. However, it's important to note that as of now, Mounjaro is not yet available as a weight loss medication within the NHS.
The drug is approved by the Medicines and Healthcare products Regulatory Agency (MHRA) for weight management in specific patient groups: adults with a Body Mass Index (BMI) of 30kg/m² or more, as well as those with a BMI between 27-30kg/m² who have weight-related health problems.
Access via NHS and Private Clinics
For patients in England and Northern Ireland, Mounjaro has been available for Type 2 diabetes management since March 2024, especially for those unable to access other medications. Although weight loss injections, including Mounjaro for weight management, are mostly prescribed by specialist weight management clinicians within the NHS, general practitioners (GPs) currently do not prescribe these injections. Changes are being proposed to introduce new prescribing pathways, potentially allowing broader access later in the year.
In addition to NHS pathways, private clinics offer another route for obtaining Mounjaro. These clinics can provide prescriptions for Mounjaro, ensuring that patients can access the treatment even if they do not meet the stringent criteria set by NHS pathways. For instance, the pre-filled Mounjaro KwikPen, approved by the MHRA, is available through both NHS and private clinics, offering doses ranging from 2.5mg to 15mg.
Current Prescription Guidelines
Mounjaro is administered as a once-weekly injection under the skin. The starting dose is typically 2.5mg once a week for the first four weeks, before increasing to 5mg once a week. The dose may be further increased in 2.5mg increments, up to a maximum of 15mg per week, depending on the patient's response and as recommended by their doctor. The treatment is combined with a reduced-calorie diet and increased physical activity to maximize its effectiveness.
The safety and effectiveness of the four-dose Mounjaro KwikPen have been validated through extensive global clinical trials. Trials have demonstrated significant reductions in fasting glucose levels and body weight among participants compared to placebo or other active controls. Common side effects include gastrointestinal symptoms like nausea, vomiting, and diarrhoea, as well as potential hypoglycemia in diabetic patients.
