Trulicity (dulaglutide) is one of the most widely prescribed GLP-1 medications in the United States, used by millions of people to manage type 2 diabetes — and, increasingly, for weight management. But a growing wave of lawsuits alleges that the drug's manufacturer, Eli Lilly, failed to adequately warn patients and doctors about serious gastrointestinal side effects, including gastroparesis (stomach paralysis), intestinal blockage, and other life-altering injuries. If you took Trulicity and suffered severe side effects, you may be entitled to compensation.
This guide explains the Trulicity lawsuits, who qualifies, what compensation may be available, and how to file a claim in 2026.
What Is Trulicity?
Trulicity is a once-weekly injectable medication in the GLP-1 receptor agonist class, approved by the U.S. Food and Drug Administration (FDA) in 2014. It works by mimicking the hormone GLP-1, which stimulates insulin production, suppresses glucagon, and slows gastric emptying — the rate at which food leaves the stomach. This combination helps control blood sugar in people with type 2 diabetes, and it also reduces appetite, which is why GLP-1 drugs have become popular for weight loss.
Trulicity is manufactured by Eli Lilly and Company, the same company behind Mounjaro and Zepbound. Like other GLP-1 drugs — including Ozempic, Wegovy, Rybelsus, and Saxenda — Trulicity's mechanism of delaying gastric emptying is central to both its benefits and its alleged risks. When gastric emptying slows too much, food can remain in the stomach for dangerously long periods, leading to the severe conditions at the heart of the lawsuits.
The Trulicity Lawsuits: What Are Plaintiffs Alleging?
Trulicity lawsuits are part of the broader GLP-1 litigation consolidated in a federal multidistrict litigation (MDL). Plaintiffs make several core allegations:
- Failure to warn: Eli Lilly allegedly knew — or should have known — that Trulicity could cause gastroparesis, intestinal blockage (ileus), and other severe gastrointestinal injuries, but failed to include adequate warnings on the drug's label or in its marketing materials.
- Defective design: Plaintiffs argue that the drug's design is unreasonably dangerous because the risk of severe, long-lasting gastric paralysis outweighs its benefits for many patients, particularly given that safer alternatives or clearer warnings were possible.
- Negligent and misleading marketing: Lawsuits allege that Eli Lilly aggressively marketed Trulicity while downplaying the severity and permanence of its gastrointestinal risks, emphasizing benefits for blood sugar control and weight management without giving patients and doctors a fair picture of the dangers.
A key theme across GLP-1 litigation is that the drug labels for years described nausea, vomiting, and abdominal pain as common, typically mild side effects — but did not adequately convey that some patients would develop gastroparesis, a chronic condition in which the stomach cannot empty properly, or intestinal obstruction requiring emergency surgery. Plaintiffs argue that had they and their doctors known the true risks, they would have chosen a different treatment or monitored for warning signs much earlier.
Serious Side Effects Linked to Trulicity
Not every side effect qualifies for a lawsuit. The Trulicity litigation focuses on severe, often long-lasting injuries. The most commonly cited include:
Gastroparesis (Stomach Paralysis)
Gastroparesis is a condition in which the stomach muscles slow down or stop working, so food remains in the stomach far longer than normal. Symptoms include persistent nausea, vomiting (sometimes of undigested food eaten hours earlier), severe bloating, abdominal pain, feeling full after eating only a small amount, acid reflux, and unpredictable blood sugar swings. In severe cases, gastroparesis can cause malnutrition, dehydration, dangerous weight loss, and hospitalization. For some patients, the condition persists long after stopping Trulicity — and may be permanent.
Intestinal Blockage (Ileus)
Ileus is a temporary lack of movement in the intestines that prevents food, fluid, and gas from passing through. Symptoms include severe abdominal pain and cramping, bloating, constipation, inability to pass gas, nausea, and vomiting. Ileus can require hospitalization, nasogastric decompression, IV fluids, and in some cases emergency surgery. Intestinal blockages can be life-threatening if not treated promptly.
Pancreatitis
Inflammation of the pancreas is a known serious risk associated with GLP-1 drugs. Acute pancreatitis causes severe upper abdominal pain (often radiating to the back), nausea, vomiting, fever, and a rapid pulse. It can require hospitalization and, in severe cases, lead to pancreatic tissue death, organ failure, or death. Chronic pancreatitis can cause permanent digestive problems and diabetes.
Gallbladder Disease
Rapid weight loss and GLP-1 use have been linked to gallstones and gallbladder disease, including cholecystitis (inflammation of the gallbladder). Many patients have required gallbladder removal surgery (cholecystectomy). Symptoms include sudden, intense pain in the upper right abdomen, pain between the shoulder blades, nausea, fever, and jaundice.
Vision Loss (NAION)
Some GLP-1 lawsuits and studies have raised concerns about non-arteritic anterior ischemic optic neuropathy (NAION), a rare but serious condition that can cause sudden vision loss. While the link is still being studied, plaintiffs with vision damage after Trulicity use are being evaluated for inclusion in the litigation.
Severe Dehydration and Malnutrition
Prolonged vomiting, inability to eat, and chronic gastroparesis can lead to severe dehydration, electrolyte imbalances, kidney damage, and malnutrition. Some patients have required feeding tubes or long-term nutritional support.
Who Qualifies for a Trulicity Lawsuit?
You may qualify to file a Trulicity lawsuit if you meet the following criteria:
- You took Trulicity (dulaglutide) as prescribed by a doctor.
- You were diagnosed with a qualifying severe injury, such as gastroparesis, intestinal blockage/ileus, pancreatitis, gallbladder disease requiring surgery, or another serious gastrointestinal condition.
- Your injury occurred after starting Trulicity and your medical records support a connection between the drug and your condition.
- You sought medical treatment for your injury, including hospitalization, emergency care, surgery, or ongoing specialist treatment.
Qualification is evaluated on a case-by-case basis. Factors that strengthen a claim include: a clear timeline (injury after starting Trulicity), a formal diagnosis confirmed by gastric emptying studies or other diagnostic tests, significant medical expenses or lost income, and evidence that you were not adequately warned of the risk. Even if you stopped taking Trulicity, you may still qualify if your injury was caused by the drug. Family members of patients who died from Trulicity-related complications may be able to file a wrongful death claim.
Compensation Available in Trulicity Lawsuits
Compensation in a Trulicity lawsuit may cover:
- Medical expenses: Past and future costs, including emergency room visits, hospitalizations, surgeries, diagnostic tests (gastric emptying studies, endoscopies, CT scans), specialist visits, medications, feeding tubes, nutritional support, and ongoing treatment.
- Lost wages and earning capacity: Income lost during treatment and recovery, as well as reduced earning capacity if your condition prevents you from returning to your previous work.
- Pain and suffering: Compensation for physical pain, chronic nausea, vomiting, abdominal pain, emotional distress, anxiety, depression, and reduced quality of life.
- Loss of enjoyment of life: Inability to eat normally, socialize, travel, exercise, or participate in activities you once enjoyed.
- Punitive damages: In some cases, additional damages intended to punish the manufacturer for particularly egregious conduct, such as concealing known risks.
- Wrongful death damages: For families of patients who died, funeral and burial expenses, loss of financial support, loss of companionship, and related damages.
Trulicity Settlement Values in 2026
It is impossible to predict the exact value of any individual case, because settlement amounts depend on the severity of the injury, the strength of the evidence, medical costs, and the impact on the plaintiff's life. However, mass tort attorneys generally describe cases in tiers:
- Higher-value cases: Patients with permanent gastroparesis requiring a feeding tube, multiple surgeries, intestinal blockage requiring emergency surgery, severe pancreatitis with hospitalization, or wrongful death. These cases typically involve the largest medical bills and the most profound life impact.
- Mid-range cases: Patients with gastroparesis or intestinal blockage confirmed by diagnostic testing, hospitalization, and ongoing treatment, but without permanent feeding-tube dependence.
- Lower-value cases: Patients with documented gastrointestinal injuries that resolved after stopping Trulicity, with shorter hospital stays and fewer long-term effects.
GLP-1 litigation is still developing, and no global settlement has been finalized as of 2026. Bellwether trials — early test cases in the MDL — will play a major role in shaping future settlement values. Your attorney can evaluate where your case likely falls based on the current state of the litigation.
Lawsuit vs. Class Action vs. MDL: What's the Difference?
Individual lawsuit: You file your own case. Your compensation is based on your specific injuries and damages. This is the most common path in pharmaceutical litigation.
Class action: A large group of people with similar claims is treated as a single class, and any settlement is divided among class members. Class actions are less common in drug injury cases because injuries vary widely from person to person.
Multidistrict litigation (MDL): The most common structure for GLP-1 cases. Individual lawsuits from across the country are consolidated before one federal judge for coordinated pretrial proceedings (discovery, expert testimony, bellwether trials). Each plaintiff keeps their own case and their own settlement based on their individual injuries — the MDL simply makes the process more efficient. Trulicity cases are part of the GLP-1 MDL.
How to File a Trulicity Lawsuit: 7 Steps
- See a doctor and get a diagnosis. If you have persistent nausea, vomiting, abdominal pain, or bloating after taking Trulicity, seek medical attention promptly. Ask your doctor about gastroparesis testing (such as a gastric emptying study) if symptoms persist.
- Preserve your medical records. Keep copies of all records related to your Trulicity prescription, pharmacy records, emergency room visits, hospitalizations, diagnostic tests, and specialist consultations. These records are the foundation of your claim.
- Document your symptoms and expenses. Keep a journal of your symptoms, missed work, and out-of-pocket costs. Save receipts for medications, medical bills, travel to appointments, and any home care you needed.
- Do not stop taking prescribed medication without talking to your doctor. If you are still taking Trulicity and experiencing severe symptoms, contact your doctor immediately to discuss whether to continue, adjust, or stop the medication.
- Contact a Trulicity lawyer for a free case evaluation. Most mass tort attorneys offer free consultations and work on a contingency fee basis — you pay nothing upfront, and the attorney is paid a percentage of your settlement or verdict only if you win.
- Your lawyer investigates and files your claim. Your attorney will gather your medical records, consult medical experts, and file your lawsuit in the appropriate court or join the MDL.
- Settlement or trial. Most pharmaceutical cases settle before trial. Your attorney will negotiate on your behalf. If a fair settlement is not offered, your case may proceed to trial.
Statute of Limitations: Don't Wait
Every state has a statute of limitations — a deadline for filing a lawsuit. For drug injury claims, the deadline typically ranges from 1 to 6 years depending on the state, and in many states the clock starts when you discovered (or reasonably should have discovered) that Trulicity caused your injury — this is called the "discovery rule." Because the discovery date can be disputed, it is critical to contact a lawyer as soon as possible after a diagnosis. If you miss the deadline, you may lose your right to compensation permanently, no matter how strong your case is.
How Much Does a Trulicity Lawyer Cost?
Most Trulicity lawyers work on a contingency fee basis. That means:
- No upfront fees or retainers.
- No hourly charges.
- The lawyer is paid a percentage (typically 33–40%) of your settlement or verdict — only if you win.
- If you do not recover compensation, you generally owe no attorney fees.
Ask your lawyer to explain the fee agreement in writing, including how case costs (medical record retrieval, expert witnesses, filing fees) are handled.
How to Choose the Right Trulicity Lawyer
- Mass tort experience: Choose a firm with experience in pharmaceutical and GLP-1 litigation, not just general personal injury.
- MDL involvement: Ask whether the firm is actively involved in the GLP-1 MDL and familiar with its procedures and deadlines.
- Resources: Drug injury cases require medical experts, extensive records review, and significant litigation resources. Make sure the firm has them.
- Communication: Your lawyer should explain the process clearly, keep you updated, and answer your questions.
- No pressure: A reputable lawyer will never pressure you to sign. Take your time, ask questions, and compare firms.
Common Mistakes to Avoid
- Waiting too long: Missing the statute of limitations is the most costly mistake. Contact a lawyer promptly.
- Stopping medication without medical advice: Always talk to your doctor before changing or stopping Trulicity.
- Throwing away records: Keep all prescription records, pharmacy receipts, medical bills, and correspondence.
- Posting on social media: Defense lawyers may review your social media. Avoid posting about your case, your symptoms, or activities that could be used to undermine your claim.
- Accepting a quick settlement without legal advice: Early offers may be far below what your case is worth. Have a lawyer review any offer.
- Signing anything from the drug company or its insurer: Do not sign releases or settlement documents without your lawyer's review.
Still Taking Trulicity? What Should You Do?
If you are currently taking Trulicity and experiencing severe gastrointestinal symptoms — persistent vomiting, severe abdominal pain, inability to eat, or signs of intestinal blockage — seek medical attention immediately. Talk to your doctor about whether Trulicity is still right for you, and ask about warning signs to watch for. Do not stop a prescribed diabetes medication without medical guidance, as uncontrolled blood sugar carries its own serious risks. Your doctor can help you weigh the benefits and risks and explore alternative treatments if needed.
Frequently Asked Questions
Can I file a lawsuit if I stopped taking Trulicity?
Yes. Many plaintiffs stopped taking Trulicity after developing symptoms. If your injury was caused by the drug, you may still have a claim even if you no longer take it.
What if I used Trulicity for weight loss, not diabetes?
Trulicity is FDA-approved for type 2 diabetes, but GLP-1 drugs are widely used off-label for weight management. Your use of the drug and your injury are what matter — discuss your specific situation with a lawyer.
How long does a Trulicity lawsuit take?
Mass tort cases can take 1–3 years or longer, depending on the MDL schedule, bellwether trials, and settlement negotiations. Your lawyer can give you a realistic timeline based on the current state of the litigation.
Will I have to go to court?
Most pharmaceutical cases settle before trial. However, a small number of cases are selected as bellwether trials to test the evidence. Your lawyer will prepare you if your case is selected.
What if I can't afford a lawyer?
Contingency fee arrangements mean you pay nothing upfront. If you don't win, you generally owe no attorney fees.
The Bottom Line
Trulicity has helped millions of people manage type 2 diabetes, but for some patients it has allegedly caused severe, life-altering gastrointestinal injuries that were not adequately warned about. If you took Trulicity and developed gastroparesis, intestinal blockage, pancreatitis, or another serious condition, you may be entitled to compensation for your medical bills, lost income, pain and suffering, and more. Contact a qualified Trulicity lawyer for a free case evaluation — and act promptly, because filing deadlines apply.
