In the past year, weight-loss drugs like Ozempic and Mounjaro have dominated headlines—and not just for their dramatic results.
As of August 2025, more than 2,600 lawsuits have been filed against the pharmaceutical giants behind these drugs, alleging severe and sometimes permanent side effects.
With legal analysts estimating potential liabilities could exceed $2 billion, the stakes are enormous. But what’s fact, what’s fiction—and what does this mean for patients?
Here’s a deep dive into the growing legal storm surrounding these blockbuster medications.

What’s Actually Happening With the Lawsuits?
The legal action against Novo Nordisk (makers of Ozempic, Wegovy, and Rybelsus) and Eli Lilly (makers of Mounjaro and Trulicity) centers around GLP-1 receptor agonists—a class of drugs used for type 2 diabetes and increasingly prescribed for weight loss.
Multidistrict litigation (MDL) is currently underway, consolidating over 2,600 cases into a single pretrial process under Judge Karen Spencer Marston in the Eastern District of Pennsylvania. This kind of legal structure is used for complex mass torts involving similar injuries—like asbestos or tobacco cases.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
The plaintiffs in these cases allege that the drug manufacturers downplayed serious side effects and failed to warn patients and doctors adequately.
What Side Effects Are Alleged?
The key medical complaints in these lawsuits include:
- Gastroparesis (delayed stomach emptying)
- Ileus (intestinal blockage)
- Gallbladder disease
- Persistent vomiting and dehydration
- Pancreatitis
- Vision loss from NAION (non-arteritic anterior ischemic optic neuropathy)
According to the FDA, Ozempic already lists some of these risks, including vision changes, gastrointestinal problems, and kidney damage. However, plaintiffs argue that the severity and prevalence of these side effects were underrepresented.
“Some people are going blind. They’re having intestinal issues, digestive issues—just some really severe type of injuries,” explained legal analyst Whitney Trailer in a recent televised breakdown.
How Much Could Be at Stake?
The viral claim circulating online is that damages could total over $2 billion. While this figure lacks official confirmation, it’s been cited by law firms like The Law Office of Melinda J. Helbock, which said that “analysts project total liability could exceed $2 billion as new claims surge.”
But Snopes, which rated the claim as “Mostly True”, pointed out that no public evidence verifies this exact number.

Given the ongoing nature of the MDL, the final payout could shift dramatically depending on the outcomes of bellwether trials, expert witness credibility, and how many plaintiffs ultimately qualify for compensation.
Why Are These Lawsuits Different From a Class Action?
Unlike traditional class actions, where plaintiffs share a single settlement, MDLs allow each case to be evaluated individually. That means:
- Some plaintiffs could receive significant payouts based on medical evidence of long-term or permanent harm.
- Others might receive smaller settlements—or none at all—if they can’t prove direct injury.
“Most of these kinds of cases settle,” Trailer noted. “But the damages vary widely depending on the individual’s specific injuries, lost wages, and long-term consequences.”
Some plaintiffs could receive six-figure or even seven-figure settlements, especially in cases involving permanent vision loss or life-altering digestive disorders.
What Do the Drug Companies Say?
Both Novo Nordisk and Eli Lilly have issued strong defenses.
“Semaglutide has been extensively examined… with over 33 million patient years of exposure,” a Novo Nordisk spokesperson told Snopes. “We believe the allegations in the lawsuits are without merit.”
Similarly, Eli Lilly emphasized the importance of scientific rigor, celebrating a recent court ruling that excluded two of the plaintiffs’ expert witnesses due to insufficient diagnostic evidence.

“Lilly appreciates the Court’s careful consideration… We will continue to vigorously defend against these lawsuits,” the company said.
Despite those victories, the court also allowed plaintiffs to supplement their evidence, leaving the door open for new expert testimony and medical findings.
What’s the Timeline?
According to legal analysts, the MDL is still in the discovery phase, which involves gathering medical records, expert opinions, and internal documents from the drugmakers. This process could take months—or even years.
“I don’t think we’re going to see any cases actually go to trial before 2026,” said Trailer. “The wheels of justice turn slowly—but they do turn.”
Most experts agree that the cases will likely settle before reaching full trials, especially considering the scale of the litigation and the cost of prolonged legal battles.
Could You Qualify for a Lawsuit?
Law firms are actively recruiting plaintiffs, and many have outlined eligibility criteria. You may qualify if you:
- Were prescribed Ozempic, Wegovy, Rybelsus, Mounjaro, or Trulicity
- Experienced gastroparesis, ileus, vision loss, or other serious side effects
- Have medical records to support your diagnosis
- Are within your state’s statute of limitations (typically 1–3 years)
Many firms have set up detailed FAQs and intake forms to streamline the process for potential claimants.
What Does This Mean for Patients?
Despite the legal controversy, GLP-1 drugs like Ozempic and Mounjaro remain FDA-approved and widely prescribed. Their effectiveness for managing type 2 diabetes and promoting weight loss is well documented, and millions continue to use them without major complications.

But patients should be aware of emerging risks and consult with healthcare providers about any unusual symptoms—especially severe nausea, bloating, vision changes, or persistent vomiting.
Final Thoughts
The legal storm swirling around Ozempic and similar drugs underscores a broader conversation: What’s the true cost of rapid medical innovation? While these medications have helped millions lose weight and manage diabetes, the potential for overlooked side effects is real—and potentially life-changing.
With thousands of lawsuits still pending and a likely years-long legal battle ahead, this case may become a landmark in pharmaceutical liability law. For now, patients are encouraged to stay informed, talk to their doctors, and carefully weigh the benefits and risks of any medication.
The verdict may still be years away—but the consequences are already rippling through the healthcare world.
