Ozempic and other GLP-1 receptor agonists work in part by slowing gastric emptying; in some patients this effect becomes excessive and persistent, leading to clinical gastroparesis that may continue even after the medication is stopped."},{"question":"What injuries qualify for an Ozempic lawsuit?","answer":"Gastroparesis (stomach paralysis), bowel obstruction or ileus, pancreatitis (acute or chronic), gallbladder disease requiring surgery, and aspiration injuries during anesthesia. The injury must have occurred during or shortly after GLP-1 use with no prior history of the condition."},{"question":"Which medications are included in GLP-1 litigation?","answer":"Ozempic, Wegovy, and Rybelsus (semaglutide, Novo Nordisk); Mounjaro and Zepbound (tirzepatide, Eli Lilly); and Victoza and Saxenda (liraglutide, Novo Nordisk).

MDL No. 3094 was created in August 2023 in the Eastern District of Pennsylvania, consolidating federal GLP-1 receptor agonist product liability cases against Novo Nordisk and Eli Lilly."},{"question":"How much is an Ozempic lawsuit worth?","answer":"Severe gastroparesis cases requiring surgery or ongoing treatment may be valued at $200,000 to $1 million or more; moderate cases with documented injuries may settle for $50,000 to $200,000. Projections may change as the litigation develops."},{"question":"Can I sue if I took Ozempic for weight loss rather than diabetes?","answer":"Yes. Weight loss use does not disqualify a claim, and may strengthen certain arguments since the risk-benefit calculus differs for a lifestyle medication versus a medically necessary diabetes treatment."},{"question":"Do I need to stop taking Ozempic to file a lawsuit?","answer":"No. Medication decisions should be made with your prescribing physician.
