Millions of Americans have been prescribed GLP-1 receptor agonist drugs — including Ozempic, Wegovy, Mounjaro, and Trulicity — for weight loss or diabetes management. These drugs have been heavily marketed as near-miraculous solutions for obesity, and prescriptions have surged dramatically. But a growing wave of lawsuits alleges that the manufacturers of these drugs failed to adequately warn patients and doctors about the risk of serious, potentially life-altering injuries.
If you or a loved one took a GLP-1 drug and suffered a severe adverse event — particularly gastroparesis (stomach paralysis), bowel obstruction, intestinal blockage, vision loss, or pancreatitis — you may have a legal claim as part of what is becoming one of the largest mass torts in American legal history.

What Are GLP-1 Drugs?
GLP-1 (glucagon-like peptide-1) receptor agonists are a class of medications that mimic a hormone in the body that regulates blood sugar and appetite. They work in part by slowing gastric emptying — meaning food stays in the stomach longer, which reduces hunger and helps with blood sugar control.
The most widely known GLP-1 drugs include:
- Ozempic (semaglutide) — approved for type 2 diabetes
- Wegovy (semaglutide, higher dose) — approved for chronic weight management
- Mounjaro (tirzepatide) — approved for type 2 diabetes
- Zepbound (tirzepatide) — approved for weight management
- Trulicity (dulaglutide) — approved for type 2 diabetes
- Victoza / Saxenda (liraglutide) — approved for diabetes and weight management
- Byetta / Bydureon (exenatide) — approved for type 2 diabetes
- Rybelsus (semaglutide oral tablet) — approved for type 2 diabetes
These drugs are manufactured primarily by Novo Nordisk (Ozempic, Wegovy, Victoza, Rybelsus) and Eli Lilly (Mounjaro, Zepbound, Trulicity).
The Growing Legal Crisis: What the Lawsuits Allege
Thousands of lawsuits have been filed against Novo Nordisk and Eli Lilly, consolidated in a federal multidistrict litigation (MDL) in the Eastern District of Pennsylvania. The lawsuits allege that the manufacturers:
- Knew or should have known about the risk of severe gastrointestinal injuries and failed to adequately warn patients and doctors
- Marketed the drugs aggressively for weight loss — far beyond the approved diabetic population — without sufficient safety disclosures
- Downplayed or omitted critical safety information from drug labels and promotional materials
- Failed to conduct adequate pre-market studies on the gastrointestinal effects of long-term use at weight-loss doses
A wrongful death lawsuit filed in 2026 has further raised the stakes in this litigation, signaling that the injuries at issue are not merely uncomfortable side effects but potentially fatal conditions.
What to Look Out For: Warning Signs of a Serious GLP-1 Drug Injury
If you are taking or have taken a GLP-1 drug, watch for these signs that you may have suffered a serious adverse event. Seek emergency medical care immediately if you experience:
Gastrointestinal Symptoms
- Severe nausea that persists for days or does not respond to anti-nausea medication
- Persistent vomiting — especially vomiting undigested food eaten hours earlier
- Severe abdominal pain or cramping
- Feeling full after eating only a small amount
- Bloating, distension, or a sensation that the stomach is not emptying
- Changes in bowel habits — severe constipation or complete inability to pass stool
Symptoms of Intestinal Obstruction
- Inability to pass gas or stool
- Abdominal swelling and pain
- Vomiting bile or green/yellow material
- Signs of dehydration (dizziness, dry mouth, decreased urination)
Vision Changes
- Sudden loss of vision in one eye
- Blurred vision or darkening in one area of the visual field
- Eye pain
- Any rapid change in vision while taking a GLP-1 drug
Symptoms of Pancreatitis
- Severe, persistent pain in the upper abdomen that may radiate to the back
- Pain that worsens after eating
- Fever, nausea, and vomiting accompanying abdominal pain
If you have any of these symptoms, seek emergency medical care immediately. Do not wait. Tell the treating physician you are taking or recently stopped taking a GLP-1 medication.
Types of Injuries Linked to GLP-1 Drugs
The lawsuits against GLP-1 manufacturers center on several categories of serious injury:
Gastroparesis (Stomach Paralysis) Gastroparesis is a condition in which the stomach muscles do not function normally, severely slowing or stopping the movement of food from the stomach to the small intestine. GLP-1 drugs slow gastric emptying as part of their mechanism — but in some patients, this effect becomes permanent or severely pathological.
Symptoms include chronic nausea, vomiting, severe nutritional deficiencies, and an inability to eat normally. Gastroparesis can be permanently disabling, requiring feeding tubes, frequent hospitalizations, and a severely restricted diet for the rest of the patient’s life.
Intestinal Obstruction and Ileus Some patients have developed bowel obstructions — blockages that prevent food and waste from passing through the intestines. This is a medical emergency. Untreated, it can lead to intestinal perforation, sepsis, and death.
Surgical Complications: Aspiration During Anesthesia GLP-1 drugs slow gastric emptying, which means food remains in the stomach longer than normal. Patients undergoing surgery who failed to disclose their GLP-1 use — or whose doctors failed to account for it — have suffered aspiration of stomach contents during general anesthesia, causing aspiration pneumonia, acute respiratory failure, and death.
Vision Loss: Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) A study published in JAMA Ophthalmology found that semaglutide users face a significantly elevated risk of NAION — a condition in which blood flow to the optic nerve is disrupted, causing sudden and often permanent vision loss. NAION is sometimes called a “stroke of the eye.”
Pancreatitis GLP-1 drugs have been associated with acute pancreatitis, a painful and potentially life-threatening inflammation of the pancreas. Severe pancreatitis can cause organ failure, infection, and death.
Thyroid Cancer Animal studies have shown that GLP-1 drugs cause thyroid tumors in rodents. The drugs carry a black box warning about a potential risk of medullary thyroid carcinoma (a type of thyroid cancer) in humans. Litigation related to thyroid cancer caused by GLP-1 drugs is an emerging and rapidly developing area.
Malnutrition and Severe Weight Loss Some patients experience such extreme appetite suppression and nausea that they cannot maintain adequate nutrition, resulting in dangerous weight loss, muscle wasting, and nutritional deficiencies requiring hospitalization.
Why You Need a Lawyer
GLP-1 drug injury litigation is complex pharmaceutical mass tort litigation. You will be going up against some of the most profitable pharmaceutical companies in the world, backed by enormous legal budgets and decades of experience defending drug injury lawsuits. An experienced mass tort attorney is essential for several reasons:
- The law is complicated. Pharmaceutical product liability cases involve FDA regulatory history, clinical trial data, pharmacology, and medical causation issues that require sophisticated legal expertise.
- Causation is disputed. Drug manufacturers routinely argue that your injury was caused by your underlying condition (diabetes, obesity, etc.) rather than their drug. Attorneys work with medical experts to establish the link between the drug and your injury.
- Timing is critical. Cases in the MDL are proceeding on a court-ordered schedule. Early-filed cases may be positioned more favorably in settlement negotiations.
- Individual settlements may be available. While much of this litigation proceeds as a mass tort MDL, individual case values depend on the severity of your injuries. An attorney ensures your individual damages are fully documented and advocated for.
- You should not have to pay anything upfront. Mass tort attorneys work on contingency — you pay no fees unless you recover.

What a Mass Tort Lawyer Does in a GLP-1 Drug Case
At Howell Law Firm PC, here is how we approach a GLP-1 drug injury claim:
Evaluate Your Claim We review your medical records, prescribing history, and injury to assess whether you have a viable claim and estimate the potential value of your case.
File Your Case in the MDL We file your case in the federal multidistrict litigation (or in appropriate state court) and ensure it is properly registered before applicable deadlines.
Work With Medical Experts We engage gastroenterologists, neurologists, ophthalmologists, and other specialists to establish the causal connection between the GLP-1 drug and your specific injury.
Obtain Your Drug and Medical Records We gather your prescription history, pharmacy records, and complete medical records to document the full timeline of your drug use and your injuries.
Advocate for Your Full Damages We document all aspects of your damages: past and future medical costs, the long-term disability caused by gastroparesis or other conditions, lost income, pain and suffering, and loss of enjoyment of life.
Keep You Informed Mass tort litigation moves on its own timeline. We provide regular updates and explain every development in plain language, so you always know where your case stands.
The Importance of Keeping Your Evidence
Unlike a defective product you can set aside in a closet, the “product” in a drug case is the medication itself — along with all the records that document your use of it.
Preserve your medication. If you have unused doses — pens, vials, or oral tablets — do not throw them away. Keep the original packaging with lot numbers and expiration dates. These can be important for tracing the specific batch of medication you received.
Keep all prescriptions and pharmacy records. Your pharmacy keeps records of every prescription filled, but having your own copies ensures nothing is lost or difficult to obtain later. These records establish when you started and stopped the drug.
Keep all documentation from the prescribing physician. Records of your initial prescription, any dosage changes, discussions of risks and benefits, and any communications where you reported side effects are all critical evidence.
Do not delete digital records. Text messages, patient portal messages, or emails to or from your doctor about your symptoms may be relevant and discoverable.
The Importance of Documenting Your Injuries
In pharmaceutical injury cases, the medical record is everything. Here is how to build the strongest possible record:
Report Every Symptom to Your Doctor Do not minimize symptoms or assume they will pass on their own. Report every adverse symptom — no matter how embarrassing or minor it seems — to your doctor and ask that it be documented in your medical record.
Ask for Written Records of Your Diagnoses If you are diagnosed with gastroparesis, pancreatitis, or any other condition that may be linked to your GLP-1 drug, ask for copies of the diagnostic records, imaging studies, and physician notes.
Document the Impact on Your Life Keep a daily or weekly journal noting how your symptoms affect your ability to work, eat, care for your family, socialize, and enjoy life. These records support claims for pain and suffering and loss of enjoyment of life.
Keep All Bills and Receipts Save all medical bills, pharmacy receipts, insurance explanation of benefits forms, and out-of-pocket expense records. Hospitalizations, specialist visits, and prescription costs all factor into your damages.
Note Conversations With Your Doctor About the Drug Write down what your doctor told you about the risks of the medication, whether they mentioned the possibility of severe gastrointestinal side effects, and how they responded when you reported symptoms.
California Deadlines: Act Before Time Runs Out
In California, the statute of limitations for personal injury cases — including pharmaceutical product liability — is generally two years from the date you knew or should have known that the drug caused your injury (California Code of Civil Procedure § 335.1 and the “discovery rule”).
This is more nuanced in drug injury cases than in typical accident cases because:
- Many patients do not immediately connect their injury to their medication.
- The discovery rule starts the clock when you knew or should have known that the drug caused your injury — which in some cases may be when you first saw news coverage of the recall or lawsuit, or when your doctor first raised the possibility.
- The clock is not tolled simply because you are still receiving treatment.
Do not try to calculate this deadline yourself. The interplay between the standard statute of limitations and the discovery rule is complex, and getting it wrong means losing your right to sue permanently.
Call Howell Law Firm PC at 888-712-0017 immediately to make sure your claim is evaluated before any applicable deadline passes.
Call to Action: You Trusted Your Doctor and Your Medication
You took a prescribed medication because you trusted your doctor, the manufacturer, and the regulatory system to protect you. If that trust was betrayed — if the drug company knew about these risks and did not warn you — you deserve to be compensated for every dollar of medical expense, every day of lost work, every moment of pain, and every lasting consequence of your injury.
The GLP-1 mass tort is one of the largest and fastest-growing pharmaceutical litigation matters in the country. Every day, more cases are filed and the evidence against manufacturers grows stronger. But deadlines apply, and the sooner you act, the better positioned your case will be.
Howell Law Firm PC is ready to fight for you. Call 888-712-0017 today for a free, confidential consultation. We handle GLP-1 drug injury cases on a contingency fee basis — you pay nothing unless we recover for you.
