The Wegovy lawsuit involves a growing wave of legal actions against Novo Nordisk, the manufacturer of Wegovy, a popular prescription medication approved for weight loss. Plaintiffs allege that the drug caused serious and sometimes life-altering side effects, including gastroparesis (stomach paralysis), intestinal blockages, vision loss, and blood clots, and that Novo Nordisk failed to adequately warn consumers about these risks. The litigation, consolidated into multidistrict litigation (MDL) in federal court, seeks to hold the pharmaceutical company accountable for harms caused by the drug and its aggressive marketing.
Background of the Wegovy Lawsuit
Wegovy, containing the active ingredient semaglutide, was approved by the FDA in 2021 as a treatment for obesity. It works by mimicking a hormone that regulates appetite, and its success spurred widespread use. However, stemmed from prior uses of semaglutide in diabetes medication (Ozempic), significant adverse health events involving gastrointestinal injuries and vision problems have been reported. Plaintiffs allege that Novo Nordisk was aware or should have been aware of these risks but failed to disclose them sufficiently, especially with the higher dosage used in Wegovy for weight loss.
The lawsuits began surfacing in 2023 and 2024, culminating in the formation of the multidistrict litigation (MDL 3094) in Pennsylvania, uniting over 2,000 cases involving Wegovy and similar drugs under the GLP-1 receptor agonist class.
