Mounjaro Lawsuits

Mounjaro, manufactured by Eli Lilly and Co., is an injectable prescription medicine that is used along with diet and exercise to improve blood sugar in adults with type 2 diabetes mellitus. Mounjaro received FDA approval in May of 2022. 

Mounjaro is a glucagon-like peptide-1 (GLP-1) receptor agonist, like Ozempic, which is produced by Novo Nordisk. In addition, Mounjaro also activates glucose-dependent insulinotropic peptide (GIP), a hormone that helps release insulin after consumption.

Eli Lilly claims on the Mounjaro website that studies showed 3 out of 4 people reached an A1C under 7%, from an average starting at 7.9% to 8.6%.

They further claim that people taking Mounjaro lost up to 25 lbs, though they state that Mounjaro is not intended as a weight loss drug. Nonetheless, it is already being prescribed off-label for weight loss. The FDA is reviewing the results of a clinical trial to determine if the drug can be specifically used for that purpose.

Potential side effects of Mounjaro

In the midst of the flurry of excitement over this new drug, lawsuits have already begun due to serious medical problems caused by Mounjaro. Potential side effects listed by Mounjaro include:

  • Thyroid tumors and thyroid cancer
  •  Inflammation of the pancreas
  • Hypoglycemia
  • Serious allergic reactions
  • Kidney problems and kidney failure
  • Severe stomach problems
  • Changes in vision
  • Gallbladder problems 

The most common side effects are nausea, diarrhea, decreased appetite, vomiting, constipation, indigestion, and abdominal pain.


Many people across the country are reporting adverse events due to the use of Mounjaro, Ozempic, and other GLP-1 agonist drugs, including serious side effects such as:

  • gastroparesis (paralysis of the digestive muscles)
  • excessive vomiting
  • severe diarrhea and dehydration
  • severe abdominal pain and gastrointestinal burning
  • gastric obstruction, and other serious gastric distress 

Though Mounjaro and similar drugs list gastric disturbances among possible side effects, gastroparesis is a permanent, debilitating condition that can dramatically decrease a person’s quality of life for years to come, and many people believe that insufficient warning was given regarding the possibility of this very serious outcome. 

Gastroparesis can severely affect a person’s health, since the ability to digest food is compromised, leading to changes in blood sugar levels and nutritional absorption, severe dehydration, weight loss, and malnutrition. 

Because there is no cure for gastroparesis, plaintiffs are seeking compensation for pain and suffering, loss of quality of life, and past and future medical expenses.

As of October 2023, there is no class action or multi-district litigation for injuries caused by Mounjaro, therefore personal injury lawyers are filing individual lawsuits against Eli Lilly.

If you believe you have suffered serious harm to your health by using Mounjaro or some other medical product, you may have the right to sue and receive compensation. As an experienced personal injury attorney and lifelong Florida resident, I believe in “fighting for the rights of the little guy” against the highly lucrative businesses, insurance companies, and medical institutions that have the financial resources to squash your efforts to recover damages due to negligent behavior or faulty products.
