Mounjaro, Ozempic, Wegovy - The Weight Loss Revolution

 From Diabetes Treatment to Weight Loss Revolution

India is undergoing a significant transformation in metabolic health, marked by a sharp rise in diabetes and obesity cases. Modern lifestyles have led to a significant rise in obesity rates across many countries. On the flip side, today, social media strongly emphasizes looking good and staying healthy. This increased interest in weight-loss treatments. Fortunately, new treatments, awareness programs and medical advances are changing how these conditions are dealt with.

Power Drugs

March 2025 marked the launch of the breakthrough drug Mounjaro (Generic name: Tirzepatide) in India. Mounjaro is a prescription medication used primarily to treat Type 2 Diabetes.

How Mounjaro Works

Mounjaro activates two important hormones in the body:

• GLP-1 (glucagon-like peptide-1)
• GIP (glucose-dependent insulinotropic polypeptide)

This dual-hormone action enhances blood sugar regulation and suppresses appetite, supporting weight loss. By September it had become one of India’s top-selling branded drugs because of the high demand for diabetes and obesity treatment. Since its approval by the U.S. Food and Drug Administration in 2022, Mounjaro has emerged as one of the most promising therapies for metabolic diseases.

Ozempic Launched

December 2025 saw the launch of Ozempic in India. It is available in 0.25 mg, 0.5 mg and 1mg doses. This prescription drug typically costing approx. Rs 8800 to 11175 per month. It is approved by the Central Drugs Standard Control Organization (CDSCO) for adults with type 2 Diabetes.

How Ozempic Works

Ozempic contains Semaglutide. Unlike Mounjaro, it mimics only GLP-1, which plays a key role in regulating blood sugar levels and appetite. By stimulating insulin production, slowing digestion, and reducing hunger, it often leads to substantial weight loss.

Originally developed for people with Type 2 Diabetes, Ozempic attracted global attention due to its unexpected effects - Significant weight loss. However, there is lot of controversy surrounding Ozempic because of its use for weight loss rather than diabetes treatment. In many countries, the drug has become popular among celebrities and social media influencers who are seeking rapid weight reduction.

Scene Stealer Wegovy

But it raises a question! Ozempic was launched internationally in December 2017 while Mounjaro had an international launch in May 2022. Then why was Ozempic launched in India after Mounjaro?

This was primarily to manage global supply shortage. The global demand for Ozempic was extremely high so they wanted to ensure a stable supply before entering a huge market like India. This way the patients would not start treatment and then have to deal with shortages.

Also, the manufacturers wanted to prioritize the introduction of their weight loss-specific drug Wegovy in India first rather than focusing initially on the diabetes-focused Ozempic.

Advantage Mounjaro

Thus, their competitor launched Mounjaro and took an early share of the market in India, To counter this, Ozempic entered the Indian market with a competitive lower-priced strategy. Typical monthly cost of Mounjaro is between 13,000 to 25,000 while that of Ozempic ranges from Rs 9000 to 20,000 and Wegovy is Rs 10000 to 17000 per month.

But there is a heavier price too!

Many people experience mild digestive side effects like Nausea, Diarrhea, Vomiting, Constipation, Stomach discomfort and Loss of appetite. Most of these symptoms improve as the body adjusts to the medication. Doctors usually start patients on lower doses and gradually increase them.

Rare but serious side effects

• ·        Pancreatitis
• ·         Gallbladder disease
• ·         Kidney problems
• ·         Severe allergic reactions

Hence for safe use, it should always be prescribed and monitored by a healthcare professional.

Figures from studies suggest the following average weight loss:

• Mounjaro - 15–22% body weight loss
• Wegovy - 12–15% body weight loss
• Ozempic - 8–12% body weight loss

However, the results vary depending on:

• Lifestyle
• Diet
• Physical activity
• Dosage

Celebrity Favourite

Some celebrities rumored to have used Ozempic or similar drugs include Elon Musk, Kim Kardashian and Oprah Winfrey, to name a few. Bollywood personality Karan Johar is being ridiculed for having an ‘Ozempic Face’. Many other international celebrities and Bollywood personalities have not officially confirmed using these medications specifically. The list of celebrity users coupled with the cost of the medications places it in the elite class of drugs. This raises questions about healthcare inequality.

Looking Ahead

To end on a positive note, the most significant development is the expiry of the semaglutide patent on March 20, 2026. This will lead to the emergence of generic Ozempic from domestic pharma giants. Over 50 Indian companies like Sun Pharma, Zydus Lifesciences, Dr. Reddy’s and Lupin have received approval to launch their own versions. New generics are expected to enter the market at Rs   3,500 to 5,000, making the treatment accessible to a much larger segment of the population.
