How Much Do Weight Loss Injections Really Cost?#
If you're considering weight loss injections in the UK, the cost comparison between Ozempic, Mounjaro and Wegovy isn't straightforward. Private prescriptions range from £150-350 monthly, but NHS availability depends on strict criteria. Here's what each medication actually costs and when you might get them for free.
Understanding These Three Medications#
All three belong to the GLP-1 receptor agonist family, but they're not identical twins. Ozempic contains semaglutide and was originally developed for type 2 diabetes. Wegovy also contains semaglutide but at higher doses specifically for weight management. Mounjaro (tirzepatide) is the newest player, targeting both GLP-1 and GIP receptors.
The key difference? Mounjaro often produces greater weight loss - around 20% of body weight in trials compared to Wegovy's 15% average. But this doesn't automatically make it better value for money.
NHS Availability: When You Pay Nothing#
Getting these medications on the NHS dramatically changes the cost equation. You'll pay standard prescription charges (currently £9.90 per item in England) or nothing if you're exempt.
Wegovy on the NHS: Available since September 2023, but with tight criteria. You need a BMI of 35+ with weight-related health problems, or BMI 30+ with specific conditions like type 2 diabetes. You must also complete a specialist weight management programme first.
Mounjaro on the NHS: Approved by NICE in March 2024 under similar criteria to Wegovy. Rollout is gradual, so availability varies by area. Some NHS trusts prioritise patients who've tried other weight loss medications first.
Ozempic on the NHS: Only prescribed for type 2 diabetes, not weight loss. Using it off-label for weight management means private prescription only.
Waiting times for NHS weight loss injections typically range from 3-12 months depending on your local area and how quickly you can access specialist services. Private weight loss injection pricing (UK)
