What to Know About the Latest Updates in Ozempic and Wegovy Lawsuits

Key takeaways:

  • Lawsuits claim that Novo Nordisk, the manufacturer, did not sufficiently warn doctors and patients about the risk of severe gastrointestinal conditions like gastroparesis, or “stomach paralysis.”
  • To manage the large number of cases, federal lawsuits have been consolidated into a multidistrict litigation (MDL) in the Eastern District of Pennsylvania, a key venue for residents of Pennsylvania and New Jersey.
  • The primary injury cited in these claims is severe gastroparesis, a condition where the stomach cannot empty itself properly, leading to chronic vomiting, pain, and malnutrition.

The legal claims against Novo Nordisk are not about banning the drug. They are about accountability and informed consent. The core of these lawsuits is the product liability principle known as “failure to warn.”

A Manufacturer’s Duty to Consumers

Pharmaceutical companies have a legal duty to inform the medical community and the public about the known risks of their products. This information allows doctors and patients to make educated decisions about their healthcare. 

Plaintiffs in the Ozempic and Wegovy lawsuits argue that the manufacturer knew, or should have known, about the potential for severe stomach paralysis but did not reflect this danger on the warning label.

Distinguishing side effects from severe injury

Many medications have mild, temporary side effects. The warning labels for these drugs did mention nausea and vomiting. 

However, the lawsuits contend that the manufacturer’s warnings did not prepare anyone for the severity, permanence, and debilitating nature of conditions like gastroparesis, a condition that is a complete and often irreversible shutdown of stomach function.

Centralization of lawsuits 

As individuals nationwide filed lawsuits with similar allegations, the federal court system recognized the need for a more efficient process. This led to the creation of multidistrict litigation, or MDL.

In February 2024, a judicial panel issued a transfer order to consolidate all federal Ozempic and Wegovy lawsuits into a single proceeding. This MDL, assigned to the Eastern District of Pennsylvania in Philadelphia, streamlines pretrial activities. 

An MDL is not a class-action lawsuit; each plaintiff’s case remains individual.

Managing these complex cases requires a structured approach. The MDL process helps coordinate evidence gathering and legal rulings, which is beneficial for plaintiffs with similar claims.

Why the eastern district of Pennsylvania matters

The selection of Philadelphia as the venue for this MDL is significant for people in the region. With Stark & Stark’s offices in both Pennsylvania and New Jersey, our personal injury attorneys are positioned to represent local clients in this national litigation. It allows for direct participation in a legal process happening right in our community.

Gastroparesis: The Heart of the Claims

The primary injury alleged in these lawsuits is gastroparesis, a medical term for stomach paralysis. This condition is devastating and can require lifelong medical management. It occurs when the stomach muscles no longer function to move food into the small intestine.

Stomach paralysis

For those affected, gastroparesis means living with constant nausea, frequent and violent vomiting of undigested food, severe abdominal pain, and significant weight loss. 

Patients may require feeding tubes to get necessary nutrition. The condition profoundly impacts a person’s ability to work, socialize, and lead a normal life.

If you believe you have been harmed by one of these medications, taking organized steps can help protect your health and your legal rights. 

Your immediate focus should be on your medical care and documenting your experience.

  • Continue to follow the advice of your treating physicians.
  • Keep a detailed journal of your symptoms, medical appointments, and daily challenges.
  • Gather all prescription records showing your history of using the medication.
  • Preserve any communications you have had with your doctor about your side effects

This information provides the factual foundation an attorney needs to evaluate your potential claim and advise you on the next steps.

Connecting the drug’s action to the injury

Ozempic and Wegovy belong to a class of drugs called GLP-1 receptor agonists. They work in part by slowing down digestion, which helps control blood sugar and makes a person feel full longer. The lawsuits allege that this slowing effect goes too far in some people, leading to a near-complete shutdown of stomach motility.

What to Expect as the Litigation Moves Forward

Now that the MDL is established, the litigation enters a critical phase of evidence gathering and legal arguments. The process will take time, but it is a necessary step toward uncovering the facts.

The court will establish a schedule for attorneys to exchange documents and take testimony from company employees, medical experts, and the plaintiffs themselves. 

FAQ for Ozempic and Wegovy Lawsuits

What specific drugs are included in these lawsuits?

The current MDL primarily includes lawsuits related to Ozempic, Wegovy, and Rybelsus, all of which are manufactured by Novo Nordisk. Other similar drugs, like Mounjaro, may be subjects of separate or future litigation.

What if I was taking the drug for type 2 diabetes versus weight loss?

The reason for your prescription does not affect your eligibility to file a claim. The core issue is whether you took the drug and subsequently developed a severe, improperly warned-of condition like gastroparesis, regardless of the initial diagnosis.

How do I prove the medication caused my stomach condition?

Your attorney will work with medical experts to establish a causal link. This involves a thorough review of your medical records to show a clear timeline between starting the medication and the onset of severe gastrointestinal symptoms, while also working to rule out other potential causes.

Is it too late to file a lawsuit?

Each state has a statute of limitations, which is a deadline for filing a product liability claim. Because the knowledge of this potential link is relatively new, it is crucial to speak with an attorney as soon as possible to protect your right to file.
