In clinical trials, people with type 2 diabetes taking Mounjaro (tirzepatide) for blood sugar control lost up to 13.9% of their body weight in 104 weeks. If you weigh 250 pounds, that’s almost 35 pounds — roughly the weight of a 3-year old!

Mounjaro is a name-brand injectable medication with the active ingredient tirzepatide. It was U.S. Food and Drug Administration (FDA)-approved in May 2022 to be used with diet and exercise to improve glycemic (blood sugar) control for adults with type 2 diabetes.
In trials though, people didn’t just improve blood sugar control and reduce their A1C levels using Mounjaro, they also lost weight.
Mounjaro is prescribed off-label for weight loss. And Eli Lilly got a version of tirzepatide branded as Zepbound FDA-approved just for weight loss in November 2023. People who are medically obese or overweight with at least one weight-related health problem, like high blood pressure, type 2 diabetes, heart problems, or high cholesterol can take it. They also need to eat fewer calories and be more active.
Both Mounaro and Zepbound have become popular alongside weight loss injection medication Wegovy (semaglutide) and Ozempic (semaglutide), a med for type 2 diabetes that’s also used off-label for weight loss.
Mounjaro’s active ingredient, tirzepatide, is a glucagon-like peptide-1/gastric inhibitory polypeptide (GLP-1/GIP) dual agonist. Mounjaro was the first GLP-1/GIP approved by the FDA, followed only by Zepbound so far.
GLP-1 and GIP are natural hormones that hamper glucagon secretion, promote insulin secretion, and slow how fast food leaves the stomach. GLP-1/GIP dual agonists mimic these hormones and bind to GLP-1 and GIP receptors, which makes you want to eat less among other things.
Bottom line: when you use Mounjaro while eating a reduced-calorie diet and being more physically active, you improve blood sugar control, feel more full, and have less appetite, so you eat less and lose weight.
In clinical trials, people with type 2 diabetes lost up to 13.9% of their body weight in 104 weeks while taking 5, 10, or 15 milligrams of tirzepatide. In other studies, people without type 2 diabetes and with obesity or overweight lost up to 20.9% of their body weight in 72 weeks on 15 milligrams of tirzepatide.

Mounjaro is FDA-approved for people who have type 2 diabetes. It’s intended to be used along with diet and exercise to improve glycemic control, also known as blood sugar or glucose control, in adults with type 2 diabetes.
Mounjaro isn’t approved for weight loss, but it has been used off-label (for something it’s not approved for) for weight loss.
Finding Mounjaro starts with having a prescription. A trained, licensed healthcare provider can prescribe Mounjaro or another medication for type 2 diabetes treatment or weight loss if they feel it’s medically necessary for you. Providers who can prescribe medications include physician assistants (PAs), medical doctors (MDs), and nurse practitioners (NPs).
You can find a board-certified, licensed provider to discuss a medical weight loss program that may include medication, such as Mounjaro, on Klarity.
With a prescription, you can get Mounjaro at any pharmacy — online or local — that has it in stock.
Popular medications used for weight loss — including medications for type 2 diabetes used off-label for weight loss — have had supply shortages in recent years. Mounjaro and Zepbound have both been affected by shortages. Before you start one, check the FDA drug shortages database for availability — search for tirzepatide.
Like other injections for weight loss and type 2 diabetes, Mounjaro is taken once a week. It comes in 2.5-, 5.0-, 7.5-, 10.5-, 12.5-, and 15-milligram prefilled single-dose pens. You inject yourself under the skin, usually in your belly, upper thigh, or in the back of your arm. You can also have someone else inject you.
When you start taking Mounjaro, you take 2.5 milligrams for the first 4 weeks. The smaller dose helps minimize side effects and lets your body adjust. After 4 weeks, you take the next higher dose for 4 weeks and so on until you reach your maximum dose, which may be 5 milligrams or more.
If you don’t tolerate Mounjaro well, your provider may have you increase your dose more slowly, for example, every 8 weeks. They may also have you step back to the next smaller dose as your maintenance dose.

Side effects from Mounjaro most commonly include nausea, diarrhea, decreased appetite, vomiting, constipation, indigestion, and stomach pain. They’re usually mild to moderate and more likely when you first start Mounjaro or increase your dose.
Mounjaro can also have serious side effects, adverse reactions, and drug interactions. It also has an FDA-boxed warning for the possibility of medullary thyroid carcinoma (or MTC, a type of thyroid cancer) or multiple endocrine neoplasia syndrome type 2 (MEN2). And some people shouldn’t take it or only take it with caution.
Talk to your pharmacist or healthcare provider to learn more and to understand serious side effects, adverse reactions, Mounjaro’s boxed warning, and precautions.
The average retail price of Mounjaro, which is the price the pharmacy charges you before insurance, for all doses is $1,135 for a one-month supply.
If you have insurance that covers Mounjaro, you could pay as little as $25 for a 1-, 2- or 3-month supply with the Mounjaro Savings Card. Even if your insurance doesn’t cover it, you save $573 for a one-month supply with the card — that’s just less than 50% off. Some restrictions apply.
You can also visit SingleCareRx, drugs.com, GoodRx, WellRx, and other sites for a prescription or drug discount card to save money on the cost of Mounjaro.
Mounjaro is the same as Zepbound. Each is simply approved for different uses. They’re the only GLP-1/GIP dual agonist medications available. Ozempic and Wegovy are both GLP-1 receptor agonists and the same medication is used for different purposes and at different doses.
In separate trials, people lost more weight on Mounjaro or Zepbound than other medications, including Ozempic, Wegovy, Saxenda (liraglutide), Qsymia (phentermine-topiramate), Contrave (bupropion-naltrexone), Adipex-P (phentermine), and Xenical (Orlistat). Mounjaro costs around $400 less a month than Ozempic or Wegovy, but about $10 more than Zepbound.
Whether you use Mounjaro or another medication, only you and your healthcare provider can decide which weight loss plan and medication, if applicable, is right for you.
Saxenda, Contrave, Qsymia, Adipex-P, Xenical, and Wegovy are all FDA-approved for weight loss or weight management in people with obesity and overweight when combined with a reduced-calorie diet and increased physical activity. All have side effects that may include, but aren’t limited to, nausea, vomiting, constipation, diarrhea, and headaches. Phentermine is a controlled substance and can increase heart rate or blood pressure and cause dependency and misuse.
