Ozempic Pancreatitis Lawsuit

Part of the Ozempic / GLP-1 investigation

The short answer

The JAMA 2023 study found a 9.09x increased risk of pancreatitis among GLP-1 users for weight loss. Acute pancreatitis can be life-threatening and requires hospitalization.

GLP-1 Drugs and Pancreatitis Risk

GLP-1 receptors are present on pancreatic acinar cells, and overstimulation of these receptors may trigger acute pancreatitis — a painful and potentially fatal inflammation of the pancreas. The Sodhi et al. JAMA 2023 study found the strongest risk elevation for pancreatitis among all GI outcomes: a hazard ratio of 9.09 among weight-loss GLP-1 users.

Acute Pancreatitis Symptoms and Severity

Symptoms include severe upper abdominal pain radiating to the back, nausea, vomiting, and fever. Severe pancreatitis can lead to organ failure, pancreatic necrosis, and death. Hospitalization is required for most cases. Recurrent pancreatitis can lead to chronic pancreatitis — a permanent condition with ongoing pain and digestive impairment.

The Evidence Debate

The pancreatitis risk for GLP-1 drugs has been debated. Large clinical trials (LEADER, SUSTAIN-6) showed no significant increase vs placebo, but the JAMA observational study found dramatic elevation. The difference may be explained by the clinical trial populations (diabetic patients already at risk) vs the JAMA study population (non-diabetic weight-loss patients).

Documenting Your Pancreatitis Claim

Key evidence: hospital records documenting acute pancreatitis diagnosis, lipase/amylase lab values, imaging studies (CT, MRI), timeline showing pancreatitis onset during GLP-1 use, and records showing no prior pancreatitis history.

Research & evidence

Scientific Evidence

cohort

Risk of Non-Arteritic Anterior Ischemic Optic Neuropathy in Patients Prescribed Semaglutide

Hathaway JT, Shah MP, Hathaway DB, et al. (2024). JAMA Ophthalmology

Key findings

  • Type 2 diabetes patients: 8.9% NAION risk on semaglutide vs 1.8% on non-semaglutide medications
  • Weight-loss patients: 6.7% NAION risk vs 0.8% on alternatives
  • Risk was highest in first year of use
  • Findings confirmed by Danish/Norwegian cohort study of 424,000+ patients
  • EMA required European label update; Novo Nordisk has not updated U.S. labels

Risk of Gastrointestinal Adverse Events Associated With GLP-1 Receptor Agonists for Weight Loss

Sodhi M, Rezaeianzadeh R, Kezouh A, Bhatt M (2023). JAMA

Key findings

  • Gastroparesis hazard ratio: 3.67 (95% CI 1.15-11.90)
  • Bowel obstruction hazard ratio: 4.22 (95% CI 1.02-17.40)
  • Pancreatitis hazard ratio: 9.09 (95% CI 1.25-66.00)
  • Study population was non-diabetic weight-loss patients — directly relevant to majority of MDL plaintiffs
  • Findings were robust across sensitivity analyses
meta-analysis

GLP-1 Receptor Agonists and Gallbladder Disease: A Systematic Review of Randomized Controlled Trials

Multiple authors (systematic review) (2024). Clinical Gastroenterology and Hepatology

Key findings

  • 37% increased relative risk of gallbladder disease across 76 RCTs
  • Risk was more pronounced with higher doses and greater weight loss
  • Rapid weight loss mechanism contributes to gallstone formation
  • Risk increased with duration of GLP-1 agonist use
  • Findings support inclusion of gallbladder disease in GLP-1 litigation claims

FAQ

Frequently Asked Questions

36 QUESTIONS

Over 3,100 lawsuits allege that Novo Nordisk (maker of Ozempic, Wegovy, Rybelsus) and Eli Lilly (maker of Mounjaro, Zepbound) failed to adequately warn patients and doctors about severe side effects including gastroparesis (stomach paralysis), bowel obstruction, pancreatitis, and vision loss (NAION). The cases are consolidated in MDL 3094 in the Eastern District of Pennsylvania.
