Weight Loss Injection Names in India: Every Brand Explained
'Weight loss injection' is not a drug name, it is a category. Here is every actual brand sold in India, which medicine is inside each one, and how they relate to each other.

If you have searched for the name of the weight loss injection and come back confused, that is fair. Ozempic, Wegovy, Mounjaro, Semasize, Yurpeak: these sound like competing products, but most of them are not. They are brand names sitting on top of just two actual medicines. Once you know which medicine is inside which box, the whole category stops being confusing.
There are only two medicines. Everything else is a brand name.
Every weight loss injection sold legally in India today is one of two active ingredients: semaglutide or tirzepatide. Each company that makes one of these gives it its own brand name, the way paracetamol is sold as Crocin, Calpol and Dolo, all the same molecule, different labels. Knowing the molecule, not the brand, is what actually tells you what you are taking.
| Brand name | Molecule | Made by | Notes |
|---|---|---|---|
| Ozempic | Semaglutide | Novo Nordisk | Originally approved for diabetes; used off-label and on-label for weight |
| Wegovy | Semaglutide | Novo Nordisk | Novo Nordisk's brand specifically approved for weight management, higher max dose |
| Rybelsus | Semaglutide | Novo Nordisk | Same molecule as Ozempic, in a daily tablet instead of an injection |
| Semasize | Semaglutide | Alkem Laboratories | Generic, launched after the March 2026 patent expiry, from ₹1,800/month |
| Mounjaro | Tirzepatide | Eli Lilly | Dual GIP/GLP-1 agonist, generally the strongest weight loss result in trials |
| Yurpeak | Tirzepatide | Cipla | Generic tirzepatide, same molecule as Mounjaro at a lower price |
So which one is 'the' weight loss injection?
None of them, individually. The two ingredients that do the work are semaglutide and tirzepatide. Everything with either of those inside it works the same basic way: it mimics a gut hormone that reduces appetite and slows digestion, which is why people eat less without white-knuckling it. The brand on the box changes the price and sometimes the exact approved use, not the underlying mechanism.
Semaglutide vs tirzepatide, in one line
Semaglutide (Ozempic, Wegovy, Semasize and others) acts on one hormone pathway. Tirzepatide (Mounjaro, Yurpeak) acts on two, and tends to produce more weight loss in trials, at a higher price. Read the full breakdown in our semaglutide vs tirzepatide comparison.
Why the branded price and the generic price look so different
Ozempic and Mounjaro are the original, patent-holding brands from Novo Nordisk and Eli Lilly. Semaglutide's Indian patent expired in March 2026, which is why brands like Semasize now sell the same active molecule at a fraction of the historical price. Tirzepatide brands like Yurpeak follow the same logic: same ingredient CDSCO has approved as equivalent, lower price because there is no original-brand premium attached. Neither is a lesser treatment, in the way a generic paracetamol is not a lesser painkiller than the original brand.

The name on the box does not replace a prescription
Whichever brand name you have heard, every one of these medicines is prescription-only in India for good reason: dose, contraindications and monitoring differ by person, not by brand. Anyone selling any of these names without a valid prescription is operating illegally, whatever the label says.

Key takeaways
- There are only two weight loss injection molecules sold in India: semaglutide and tirzepatide.
- Ozempic, Wegovy, Rybelsus and Semasize are all semaglutide under different brand names.
- Mounjaro and Yurpeak are both tirzepatide under different brand names.
- Generic brands (Semasize, Yurpeak and others) contain the identical active molecule as the original patent-holder brands, at a lower price.
- The brand name does not remove the need for a prescription and medical supervision.
Frequently asked questions
What is the actual name of the weight loss injection?
There isn't one single name. The two medicines used for weight loss injections in India are semaglutide (sold as Ozempic, Wegovy, Semasize and other brands) and tirzepatide (sold as Mounjaro and Yurpeak). Each company gives its version of the molecule its own brand name.
Is Ozempic the same as Wegovy?
Both contain semaglutide, made by Novo Nordisk. Ozempic was originally approved for type 2 diabetes; Wegovy is the brand specifically approved for weight management and reaches a higher maximum dose.
Is Mounjaro the same as Yurpeak?
Yes, both contain tirzepatide. Mounjaro is Eli Lilly's original brand; Yurpeak is Cipla's version of the same molecule, approved by the CDSCO after India's patent rules allowed it, sold at a lower price.
Which weight loss injection is best?
There is no single 'best' brand, only a best molecule and dose for your specific case, which a doctor decides based on your health history, BMI and goals. See our semaglutide vs tirzepatide comparison for how the two molecules differ.
