What it is
Mounjaro (tirzepatide) is a once-weekly self-injected medicine that mimics two natural gut hormones, GLP-1 and GIP, to reduce appetite and slow digestion. It's licensed for weight management in adults with a BMI of 30+, or 27+ with a weight-related health condition.
Pros and cons
Why it's good
- Currently the most effective GLP-1 medication by average weight loss in trials
- Once-weekly dosing rather than daily
- Dual hormone action may suppress appetite more than semaglutide-only options
- Available on the NHS for some patients via specialist weight management services
Why it's not for everyone
- Common side effects include nausea, diarrhoea and constipation, especially during dose increases
- Requires ongoing self-injection, which doesn't suit everyone
- Weight regain is common if treatment stops without lifestyle changes in place
- Private cost is the highest of the GLP-1 options
Who it's best for
People with a BMI in the eligible range who want the strongest average results currently available and are comfortable with weekly self-injection.
