Mounjaro is the brand name for tirzepatide, the first weight-management medicine to act on two gut hormones at once — GIP and GLP-1. Together they reduce appetite, slow stomach emptying, and improve how your body handles blood sugar.
In trials, tirzepatide produced the largest average weight reduction of any licensed GLP-1 to date. It's given as a once-weekly injection from a pre-filled pen, starting low and stepping up monthly so your body adjusts gently.

How Mounjaro works.
Tirzepatide is the first medicine to switch on two of your gut's appetite hormones at once.
tirzepatide
once weekly injection
Improves how your body uses insulin and handles fat after meals.
Curbs appetite, slows stomach emptying, and signals fullness to the brain.
Acting on both receptors is why tirzepatide tends to produce more weight loss than single-hormone GLP-1s — smaller portions feel satisfying, and cravings quieten.
Honest about side effects.
Most side effects are mild and settle within a few weeks. Starting low and titrating slowly is the single biggest lever — alongside smaller meals, good hydration, and messaging your prescriber early if nausea bites.
Common & usually mild
- Nausea
- Reduced appetite
- Diarrhoea or constipation
- Fatigue
- Indigestion
Rare & serious
Rare but serious effects include pancreatitis and gallbladder problems. Seek urgent care for severe, persistent abdominal pain.
