Why Are People Suing Eli Lilly Over Mounjaro?
People are suing Eli Lilly, the maker of Mounjaro, claiming the drug caused serious complications like stomach paralysis (gastroparesis) and intestinal blockages.
Mounjaro treats Type 2 diabetes. It’s also being used for weight loss despite not having U.S. Food & Drug Administration (FDA) approval.
However, some users say they weren’t warned about the drug’s risks.
As lawsuits emerged, multidistrict litigation (MDL) was established in Pennsylvania to handle the cases. MDLs consolidate similar lawsuits in a single federal court, streamlining legal proceedings and ensuring consistent court rulings.
A federal panel combined the Mounjaro lawsuits with other claims related to similar medications. These include Wegovy, Trulicity and Ozempic.
Case Study: Jaclyn Bjorklund Mounjaro Lawsuit
Jaclyn Bjorklund, a woman from Louisiana, sued the makers of Ozempic (Novo Nordisk) and Mounjaro (Eli Lilly). Her lawyers say the companies failed to adequately warn patients about serious stomach problems linked to the drugs.
After using Ozempic and Mounjaro for Type 2 diabetes, Bjorklund says she suffered from severe vomiting, stomach pain and gastroparesis. She was hospitalized multiple times, lost teeth from vomiting and had to take more medications to help with her symptoms.
Bjorklund claims the drugmakers knew about these risks but did not give clear warnings. She is suing for permanent injuries, pain, emotional distress and the cost of her medical care.
Common Legal Allegations in Mounjaro Lawsuits
Mounjaro lawsuits allege that Eli Lilly failed to adequately warn patients and doctors about the serious stomach problems associated with the drug. Plaintiffs claim that Eli Lilly knew or should have known about these risks but didn’t communicate them clearly.
The lawsuits also accuse the company of making misleading statements about the safety of the drug.
Some users who took Mounjaro with other medications, like those from Novo Nordisk, claim one or both caused them harm. The lawsuits seek compensation for medical costs, pain and suffering.
