Quick answer
Mounjaro is the brand name for tirzepatide, a weekly injection that works on two hunger hormones, GLP-1 and GIP. It tends to produce more weight loss than semaglutide in trials. It is prescription-only in India, and a doctor decides if it suits you.
Mounjaro is the one people call the stronger shot. Stronger is not automatically the right one for you, and here is the honest reason why.
What Mounjaro actually is
Mounjaro is the brand name for tirzepatide, a weekly injection. What makes it different from semaglutide (Ozempic and Wegovy) is that it works on two hunger hormones, GLP-1 and GIP, instead of one. That dual action is why it tends to show larger weight loss in trials.
How it works, in plain English
Both hormones quieten appetite and steady blood sugar, so you feel full sooner and stay full longer. Like all of these medicines, it works with your biology to make eating less feel natural, rather than relying on willpower.
How much weight do people actually lose?
In the SURMOUNT-1 trial, tirzepatide led to up to about 22.5% weight loss at the highest dose (NEJM, 2022), compared with roughly 15% for semaglutide in STEP 1 (NEJM, 2021). On paper that looks like a clear winner.
Why 'stronger' is not automatically right for you
A bigger average number in a trial does not mean it is the best choice for your body. The right medicine depends on your health conditions, how well you tolerate side effects, your goals, and cost. Some people do better on semaglutide. This is a decision for a doctor who knows your history, not a headline.
Is Mounjaro available in India?
Yes. Mounjaro was the first of this new wave to launch in India, in 2025, ahead of Wegovy and Ozempic (Forbes India). It is prescription-only.
What it costs, and side effects
Treat any price as a range that moves, and let a doctor confirm the current cost for your dose. The common early side effects are stomach-related: nausea, diarrhea, or stomach pain, and they usually ease as the dose is raised slowly. It is prescription-only, not for everyone, and not for use in pregnancy.
The best medicine is not the strongest one on a chart. It is the one that is right and safe for you, chosen with a doctor.
If you are weighing Mounjaro against other options, a short consult is the simplest way to get a real answer for your body.

Yes. It launched in India in 2025 and is prescription-only. A doctor screens you and decides the right medicine and dose.
