Latest Trulicity Stomach Paralysis Lawsuit Updates

The court scheduled a Rule 702 (“Daubert”) evidentiary hearing in MDL 3094 on Cross Cutting Issues 2 and 3 for September 14 through 18, 2026 [1].
The MDL, led by Judge Marston, includes personal injury claims over Trulicity, made by Eli Lilly, and other GLP-1 drugs.
April 1, 2026: JPML Report Lists 3,546 Pending Actions
The Judicial Panel on Multidistrict Litigation report dated April 1, 2026 lists 3,546 pending actions in MDL 3094 [2].
February 1, 2024: Nashville Law Firm Names Trulicity in Suit
WSMV reported that a Nashville law firm joined the people suing the makers of diabetes drugs. The firm named Trulicity among the drugs it believes cause stomach paralysis [3].
Eli Lilly, the maker of Trulicity, told WSMV it would “vigorously defend against these claims” and that its labels clearly warn of the risks of its medicines.
August 2, 2023: First GLP-1 Stomach Injury Lawsuit Is Filed
NBC News reported the first lawsuit alleging that Ozempic and Mounjaro can cause gastrointestinal injuries. It was filed for a Louisiana woman against Novo Nordisk and Eli Lilly [4].
Trulicity was not named in that suit, and the claims in the suit remain allegations rather than findings by a court.
What Is Gastroparesis?
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) describes gastroparesis, or delayed gastric emptying, as a disorder. It slows or stops food moving from the stomach to the small intestine [5].
NIDDK says it is not common: about 10 men and about 40 women out of 100,000 people have it.
Who May Be Affected?
The MDL covers people who took a GLP-1 drug, including Trulicity, and allege gastroparesis or other gastrointestinal injuries. The court calls the cases personal injury actions that stem from use of these drugs.
NIDDK lists other things that raise the risk of gastroparesis. They include diabetes, surgery on the esophagus, stomach or small intestine, and radiation to the chest or stomach area. These causes are separate from the drug allegation.
Whether you may have a claim depends on your own medical history and records. A lawyer can give you an individualized legal review of them.
Reported Injuries or Damages
Cases in MDL 3094 allege that GLP-1 drugs can cause gastroparesis and other gastrointestinal injuries. The court asks whether the defendants knew or should have known of the risk and whether they adequately warned users.
Eli Lilly and the Novo Nordisk defendants deny these allegations. In the first GLP-1 suit, filed for a Louisiana woman, she visited the emergency room several times and vomited so violently she lost teeth, the suit claims.
NBC News quoted a spokesperson for the FDA. The spokesperson said it is unclear whether GLP-1 medications contribute to gastroparesis. The agency said it will decide what actions are appropriate if new safety signals are identified.
Evidence to Preserve
Keep these items together, and do not throw away any Trulicity pens or packaging you still have:
- Pharmacy records that show your Trulicity doses and the dates you took them
- Medical records and test results for any gastroparesis diagnosis, including any gastric emptying study
- Records of other health problems and other medicines you have taken
- A symptom log that shows how your symptoms changed
- Emergency room, hospital and prescriber messages about your symptoms
- Bills and receipts for treatment related to your stomach symptoms
Filing Deadlines
State law sets the time limit for a Trulicity injury claim. The limit depends on where you live and on when the illness, injury and diagnosis happened.
Some states start the clock at diagnosis. Missing that limit can end a claim, even if your facts are strong. Ask a lawyer promptly which limit applies to your situation.
Frequently Asked Questions
Is There a Trulicity Stomach Paralysis Lawsuit?
A Trulicity stomach paralysis lawsuit exists because Trulicity is named in MDL 3094. The Judicial Panel on Multidistrict Litigation noted that each lawsuit contains substantially similar allegations about the drugs and their alleged propensity to cause gastrointestinal injuries.
Can Trulicity Cause Stomach Paralysis?
Whether Trulicity can cause stomach paralysis has not been decided by a court. Plaintiffs allege the warnings were inadequate, and the companies deny the allegations. A doctor quoted by NBC News said the problem could also stem from another illness or diabetes.
What Does the Research Say About Trulicity and Stomach Paralysis?
The research on Trulicity and stomach paralysis is unsettled, and no court has ruled on it. Dr. Shauna Levy of the Tulane Bariatric Center told NBC News she was not worried about stomach paralysis being a common problem.
Is There a Trulicity Settlement?
There is no Trulicity settlement or verdict, and none has been reported so far. The litigation is still pending, and the companies deny the allegations, so no outcome can be predicted.
Can the Public Watch the Status Conferences?
The public may watch the monthly status conferences in this litigation remotely. The judge holds them in person with leadership counsel. They are status conferences, so they are not trials and no verdict comes from them.
