Mounjaro Lawsuit

What is Mounjaro?

Mounjaro is a Type 2 diabetes drug developed by Eli Lilly and Company. The drug is taken once weekly through an injection. Patients start with a relatively low dosage of 2.5 mg and increase at regular intervals under the supervision of their doctor. Mounjaro received approval from the U.S. Food and Drug Administration (FDA) in 2022.

The active ingredient in Mounjaro is tirzepatide. It functions by simulating two separate types of hormones. This makes the drug both:

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

These two hormones play a role in regulating blood sugar levels in the body. They help the brain understand when to increase or decrease insulin production.

Mounjaro can make people feel full and decrease appetite, which sometimes results in weight loss. In this way, Mounjaro’s active ingredient, tirzepatide, is similar to semaglutide, the active ingredient in Ozempic®, Wegovy® and Rybelsus®. Doctors and researchers are still somewhat unsure why semaglutide and tirzepatide are such effective weight loss drugs, so research is ongoing.

Mounjaro, like Ozempic, is not approved by the FDA for weight loss. Using Mounjaro for weight loss is an off-label use and may come with safety risks.

Health concerns over Mounjaro

While all medicines come with warnings about potential side effects, many people are concerned about health issues that aren’t on Mounjaro’s warning label. Many of these side effects are gastrointestinal problems.

Some of the Mounjaro health concerns are about:

• Gastroparesis: This condition is sometimes referred to as “paralyzed stomach,” “stomach paralysis,” or “delayed gastric emptying.” It may cause a person’s stomach to slow or stop moving food through the rest of the digestive system. The delayed gastric emptying keeps food in the stomach, leading to a wide range of potential complications. These complications include abdominal pain, acid reflux, nausea, vomiting and more. It may result in weight loss, malnutrition and severe dehydration.
• Gastroenteritis: This condition is an inflammation of both the stomach and intestines. It may lead to diarrhea, nausea and vomiting. If left untreated, gastroenteritis can leave a person severely dehydrated, which could come with additional complications.

Mounjaro’s label does not warn users that they may experience gastroparesis. These gastrointestinal conditions, which can severely impact a person’s life, are the basis of some personal injury lawsuits.

Tirzepatide side effects also include various gastrointestinal issues commonly associated with GLP-1 drugs like Mounjaro. Serious side effects can involve chronic cyclical vomiting, intestinal obstructions, and other gastrointestinal events.

Lawsuit against Mounjaro

People are filing Mounjaro lawsuits against Eli Lilly. These lawsuits allege serious harm from using the Type 2 diabetes drug. The plaintiffs say that they’ve suffered conditions such as gastroparesis and that Eli Lilly failed to warn users about these serious risks.

Mounjaro lawsuits may claim:

• Failure to warn consumers: Plaintiffs may allege that Eli Lilly was required to disclose all of the potential harms of the drug to patients. They allege that Mounjaro either knew or should have known they could be injured by using the drug. A failure to warn lawsuit can help push for proper labeling on drugs, which helps future patients understand all associated risks.
• Breach of express warranty: Plaintiffs also allege Eli Lilly portrayed Mounjaro on its label and through advertisements as safe and that it would not cause conditions such as gastroparesis. If this express warranty had not been present, plaintiffs may not have used Mounjaro and experienced health complications.

Plaintiffs in a Mounjaro lawsuit may seek damages for:

• Health care costs from the treatment of Mounjaro complications
• Pain and suffering experienced as a result of health issues from Mounjaro
• Attorney’s fees for the costs of pursuing justice against Eli Lilly
• Punitive damages to punish Eli Lilly for its alleged disregard for public safety

The specific actions and damages of any Mounjaro lawsuit will depend on the facts of the case. Speaking with a Mounjaro lawyer can help you understand if you’re eligible to file a lawsuit against Eli Lilly.

Frequently asked questions about Mounjaro lawsuits

Is there a Mounjaro class action lawsuit?

No, a Mounjaro class action lawsuit has not yet been filed as of May 2024, but a Mounjaro GLP-1 MDL has been created.

MDLs are similar to class action lawsuits in that multiple plaintiffs’ claims against specific defendants are consolidated before one court. However, unlike class actions, each plaintiff’s case in an MDL remains individually active. MDL cases can go to trial and any verdicts or settlement can be specific to the harm that each plaintiff has suffered. Class action awards are split between all plaintiffs.

What is the difference between Ozempic and Mounjaro?

The difference between Ozempic and Mounjaro is their active ingredient. Ozempic is a formulation of semaglutide, a GLP-1 receptor agonist, and is FDA-approved to reduce cardiovascular risks. Mounjaro is a formulation of tirzepatide, a GIP receptor and GLP-1 receptor agonist. They are both approved to help people with Type 2 diabetes.

Ozempic and Mounjaro are both the subjects of ongoing litigation for injuries.

What is the difference between Wegovy and Mounjaro?

The difference between Wegovy and Mounjaro is in their active ingredients. Wegovy, like Ozempic, uses the GLP-1 receptor agonist semaglutide. Mounjaro uses tirzepatide, which is both a GLP-1 receptor agonist and GIP receptor. Wegovy, unlike Mounjaro and Ozempic, has been approved for weight loss by the FDA.

Novo Nordisk, manufacturer of Wegovy and Ozempic, and Eli Lilly, manufacturer of Mounjaro, are defendants in personal injury lawsuits.
