1. Is Mounjaro Available on the NHS for Weight Loss?
Yes, but with restrictions. The NHS follows NICE (National Institute for Health and Care Excellence) guidelines, which now include Mounjaro as an option for weight management under specific conditions.
Current NHS Criteria for Mounjaro (Weight Loss)
To qualify, you must:
- Have a BMI of 35+ (or 30+ with weight-related health conditions, e.g., high blood pressure, sleep apnoea, type 2 diabetes)
- Have tried other weight loss methods (diet, exercise, or medications like Orlistat/Wegovy) without success
- Be under specialist supervision (usually an endocrinologist or obesity clinic)
⚠ Important: Not all NHS trusts prescribe Mounjaro yet—some may still prefer Wegovy (semaglutide) or Saxenda (liraglutide).
2. How to Get Mounjaro on the NHS for Weight Loss
Step 1: Speak to Your GP
- Book an appointment to discuss weight management options.
- Your GP will check your BMI and medical history.
Step 2: Try First-Line Treatments (If Required)
Some NHS trusts require patients to try cheaper alternatives first, such as:
- Lifestyle changes (12-week diet/exercise programmes)
- Orlistat (Xenical) – A prescription weight loss pill
- Wegovy (semaglutide) – If available
Step 3: Get a Specialist Referral
If you meet the criteria but your GP can’t prescribe Mounjaro, they may refer you to:
- An NHS weight management clinic
- An endocrinologist (hormone specialist)
Step 4: Start Treatment & Monitoring
If approved, you’ll:
- Learn how to self-inject (Mounjaro is a weekly pen)
- Have regular check-ups (weight, blood sugar, side effects)
