Side effects
Rapid or significant weight loss can lead to too much muscle loss. To protect your muscles, it’s important to start a strength training program and exercise regularly while taking Mounjaro.
Tell your health care provider if you have severe stomach problems that won’t go away, including abdominal bloating or pain, acid reflux, a feeling of fullness after eating just a few bites of food, nausea, and vomiting, including vomiting undigested food eaten a few hours earlier. These may be symptoms of gastroparesis (stomach paralysis).
Use effective contraception while taking this medication. If you are pregnant, breastfeeding, or planning to become pregnant, do not take Mounjaro.
Although rare, Mounjaro caused thyroid C-cell tumors in animal studies. Mounjaro has a “black box” warning of the risk of these tumors. If you have trouble swallowing, develop hoarseness, or feel swelling or a lump in your neck, contact your health care provider immediately.
The FDA also warns not to take Mounjaro if you have a personal or family history of multiple endocrine neoplasia syndrome Type 2 or medullary thyroid cancer. Mounjaro is not appropriate for those with insulin-dependent diabetes or diabetic ketoacidosis. So, if that’s you, Mounjaro isn’t the right fit.

Interactions
Some drugs can also interact with Mounjaro, including:
- Insulin
- Sulfonylureas (these can cause blood sugar levels to drop dangerously low)
- Some birth control pills
- Other GLP-1 or GLP-1/GIP receptor agonist medications such as liraglutide, dulaglutide, or semaglutide
