Mounjaro Becomes India’s Top-Selling Drug Amid GLP-1 Shift
Mounjaro is a medicine used for diabetes and obesity treatment.
It belongs to a group of medicines called GLP-1 drugs.
In India, more patients are choosing GLP-1 injections instead of tablets.
Mounjaro became the country’s best-selling medicine during the year ending in August 2026.
Its sales were much higher than the year before.
Doctors say injections can help with weight, appetite and some body functions.
They also say once-a-week dosing can be convenient.
Earlier, many patients preferred the tablet Rybelsus.
The overall GLP-1 medicine market in India has grown very quickly since 2022.
Eli Lilly’s Mounjaro became India’s best-selling pharmaceutical brand, with ₹1,256 crore in sales for the 12 months ending August 2026.
Mounjaro sales rose 502% year over year, although units sold in August fell 43.8% from July.
Injectable GLP-1 medicines are gaining ground as demand for oral semaglutide, sold as Rybelsus, declines.
Tirzepatide, the molecule in Mounjaro, represented 62% of India’s ₹2,333-crore GLP-1 market by value.
Doctors cited weight reduction, appetite control, metabolic benefits and convenient weekly dosing as reasons for the shift toward injections.

Treatment convenience and use
Injectable GLP-1 Preference
Doctors said injections offer established roles in both diabetes and obesity treatment, weekly dosing, and potentially easier tolerability for some patients.
Oral GLP-1 Preference
Rybelsus, an oral semaglutide medicine launched in 2022, initially appealed to patients as an alternative to injections, although its demand has since declined.
Treatment benefits
Injectable GLP-1 Preference
Injectable GLP-1 treatments were described as helping reduce body weight, control appetite and improve several metabolic measures when used appropriately.
