Mounjaro (tirzepatide) has emerged as a promising treatment for Type 2 diabetes in recent years, offering improved blood sugar control and potential weight loss benefits. However, as with many new pharmaceutical drugs, Mounjaro comes with a spectrum of side effects ranging from mild to severe.
If you or a loved one has experienced serious Mounjaro side effects after receiving Mounjaro injections, you may be eligible for compensation to cover your medical expenses, lost work, pain and suffering, and other damages you suffered.
Lawsuits.com is committed to providing the public with the information they need to know to make informed decisions about the prescription drugs they take, as well as their rights and legal options after a serious drug-related illness or injury.
Mounjaro, a Type 2 diabetes treatment, has been linked to serious risks like stomach paralysis, pancreatitis, kidney issues, and other severe side effects. Legal action is being taken against Eli Lilly for failing to warn patients. If you’ve been affected, understanding your legal rights can help you seek compensation for the harm caused.
What Is Mounjaro?
Mounjaro, approved by the U.S. Food and Drug Administration (FDA) in 2022, is part of a new class of diabetes medications. It's a dual-acting, once-weekly injection targeting the GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) receptors.
Manufacturer Eli Lilly formulated Mounjaro to manage blood sugar levels while also promoting weight loss. Other prescription drugs in the same family include:
Ozempic (semaglutide) - Manufactured by Novo Nordisk
- Also available as Wegovy for weight loss
- Weekly injection
Trulicity (dulaglutide) - Manufactured by Eli Lilly (same company as Mounjaro)
- Weekly injection
Victoza (liraglutide) - Manufactured by Novo Nordisk
- Also available as Saxenda for weight loss
- Daily injection
Rybelsus (oral semaglutide) - Manufactured by Novo Nordisk
- Daily oral tablet (the only oral GLP-1 receptor agonist currently available)
Since its introduction, Mounjaro has gained popularity among individuals struggling with Type 2 diabetes and obesity. Millions of Mounjaro prescriptions have been written, reflecting its growing role in diabetes management and off-label use for weight loss.
However, as more patients use Mounjaro, reports of side effects have also increased, raising concerns about its safety profile.
Common Side Effects of Mounjaro
While Mounjaro can be effective in managing Type 2 diabetes, many users experience side effects, most of which affect the gastrointestinal system to some degree. Mounjaro patients should be aware of these potential issues so they are prepared to address them as soon as they arise:
Nausea and vomiting
Many Mounjaro users report feeling nauseated shortly after taking the medication, which can sometimes lead to vomiting. These symptoms can range from mild to severe and may interfere with daily activities.
Diarrhea
Alongside nausea, Mounjaro may cause persistent diarrhea. This can lead to dehydration if not properly managed.
Abdominal Pain
Some Mounjaro Users have reported experiencing various levels of abdominal discomfort, from mild cramps to more intense, sharp pains.
Constipation
Some patients may experience constipation as their bodies adjust to the medication.
Decreased Appetite
While this can facilitate weight loss, it may lead to inadequate nutrient intake if not monitored.
Other Common Mounjaro Side Effects
Headache
Some users report experiencing headaches, particularly in the early stages of treatment.
Fatigue
Some Mounjaro users have reported feelings of tiredness or low energy.
Dizziness
This may be related to changes in blood sugar levels or other factors.
Injection Site Reactions
As Mounjaro is administered via injection, some patients may experience redness, itching, or swelling at the injection site.
While most patients can manage these Mounjaro side effects, patients should always discuss any persistent or severe symptoms with their healthcare provider. Sometimes, these side effects may indicate much more serious problems that could disable some Mounjaro patients.
Serious Mounjaro Risks and Complications
Mounjaro is associated with several serious side effects that have raised significant concerns. Anyone who experiences these symptoms should consult with their healthcare provider right away.
Pancreatitis
Inflammation of the pancreas, or pancreatitis, is a serious condition reported in some Mounjaro users. Symptoms of pancreatitis include:
- Severe abdominal pain that may radiate to the back
- Nausea and vomiting
- Fever
- Rapid pulse
If left untreated, pancreatitis can lead to severe complications, including pancreatic cancer. Patients experiencing symptoms of pancreatitis should seek immediate medical attention.
Gallbladder problems
Mounjaro use has been associated with an increased risk of gallbladder issues, including:
- Gallstones
- Cholecystitis (inflammation of the gallbladder)
- Biliary colic (pain caused by gallstones)
These conditions can cause significant pain and may require surgical intervention in some cases.
Hypoglycemia (low blood sugar)
While Mounjaro is designed to help manage blood sugar levels, it can sometimes cause blood sugar to drop too low, especially when used in combination with other diabetes medications. Hypoglycemia symptoms include:
- Shakiness
- Dizziness
- Sweating
- Confusion
- Irritability
- Rapid heartbeat
Severe hypoglycemia can be dangerous and may require emergency treatment.
Kidney problems
Some patients have reported kidney issues while using Mounjaro. These can include:
- Acute kidney injury
- Worsening of chronic kidney disease
Doctors who prescribe Mounjaro to patients with kidney problems should closely monitor those patients
Allergic reactions
Though rare, some individuals may experience allergic reactions to Mounjaro. Symptoms can include:
- Rash or hives
- Difficulty breathing
- Swelling of the face, lips, tongue, or throat
Allergic reactions can be life-threatening and require immediate medical attention.
Stomach Paralysis (Gastroparesis): The Most Serious Mounjaro Risk
Among the reported side effects of Mounjaro, gastroparesis stands out as particularly concerning due to its potential for long-term health implications and impact on quality of life.
Gastroparesis, commonly called stomach paralysis, has become the basis for numerous Mounjaro lawsuits against manufacturer Eli Lilly.
Understanding Gastroparesis
Gastroparesis is a condition in which the stomach's muscles fail to function properly, leading to delayed gastric emptying. This means that food moves from the stomach to the small intestine much slower than it should, or in severe cases, not at all.
Symptoms of Gastroparesis
Gastroparesis symptoms may include:
- Chronic nausea and vomiting: Unlike the more common gastrointestinal side effects, these symptoms are persistent and severe in gastroparesis cases.
- Early satiety: Feeling full after eating only small amounts of food
- Abdominal pain and bloating: Often severe and lasting long after meals
- Erratic blood sugar levels: Particularly problematic for diabetic patients, as it can complicate glucose management
- Malnutrition: Due to poor nutrient absorption and reduced food intake
- Weight loss: Unintended and potentially rapid weight loss can occur.
- Acid reflux: Stomach contents may back up into the esophagus more easily.
Long-Term Complications of Gastroparesis
If left untreated or poorly managed, gastroparesis can lead to serious:
- Dehydration: Due to frequent vomiting and reduced fluid intake
- Malnutrition: The body may not absorb enough nutrients from food.
- Bacterial overgrowth: Food remaining in the stomach can lead to bacterial growth.
- Bezoars: Hardened masses of undigested food can form in the stomach.
- Decreased Quality of Life: The chronic nature of symptoms can significantly impact daily activities and overall well-being.
The Life-Altering Impacts of Serious Mounjaro Side Effects
As previously described, Mounjaro patients may experience temporary or persistent gastrointestinal issues. These Mounjaro side effects, particularly gastroparesis, can have profound and far-reaching impacts on an individual's life. Some of these impacts factor into Mounjaro lawsuits that some patients have filed against Eli Lilly:
Mental Health and Emotional Well-being
Chronic Mounjaro side effects can take a substantial toll on mental health. Patients may experience depression and anxiety as they grapple with lifestyle limitations and complex medical needs.
Feelings of isolation and frustration may become common as individuals struggle to participate in activities they once enjoyed. The ongoing stress of managing severe side effects can lead to sleep disturbances and cognitive difficulties, often described as "brain fog."
Social and Relationship Impacts
The unpredictable nature of symptoms, like severe nausea and vomiting, can make it difficult to maintain regular social engagements, leading to a sense of isolation. Romantic partnerships may face strain as roles within the relationship shift to accommodate new medical needs, physical discomfort, and emotional stress.
Family dynamics may also change, with patients potentially requiring more support for daily tasks. These challenges sometimes cause Mounjaro patients to withdraw from social circumstances and previously normal interactions.
Career and Financial Impacts
Mounjaro side effects can affect a person's professional life and financial stability. Many patients experience reduced work capacity or may be unable to work altogether, resulting in a loss of income and career advancement opportunities.
The need for frequent medical appointments and potential hospitalizations can make maintaining regular work attendance challenging. Financial strain often follows, not only from lost wages or income but also from mounting medical expenses and treatments. Long-term financial security may be compromised as individuals dip into savings or reduce retirement contributions to cover health-related costs.
Daily Life and Lifestyle Changes
Serious Mounjaro side effects often require significant changes to daily routines and lifestyle. Dietary restrictions become a central focus, with many patients requiring specialized meal planning to manage symptoms.
Mounjaro side effects can limit activities and exercise, altering one's ability to participate in previously enjoyed hobbies or sports. Daily schedules often revolve around symptom management and medical treatments, reducing spontaneity and the ability to engage in impromptu activities.
Long-term Life Planning
In the most serious cases, uncertainty surrounding the long-term prognosis of gastroparesis or other life-debilitating side effects can significantly impact an individual's ability to plan for the future.
You may need to reconsider family planning decisions and adjust career goals to align with new health realities. Retirement plans may shift, both in timing and in nature, to accommodate ongoing medical needs. The focus of life goals and aspirations often changes, with health management taking a more central role in long-term planning.
Legal Implications: Mounjaro Lawsuits
The increasing number of reported cases of gastroparesis and other severe side effects has led to a growing number of lawsuits against Eli Lilly. Mounjaro lawsuits primarily allege that the company failed to adequately warn patients and healthcare providers about the risk of gastroparesis associated with the drug.
Basis for Mounjaro Lawsuits
The main arguments in these lawsuits typically include:
- Failure to Warn: Plaintiffs argue that Eli Lilly did not provide sufficient warnings about the risk of gastroparesis on the drug's labeling or in its marketing materials.
- Negligence: Some lawsuits claim that the company negligently developed, tested, or marketed Mounjaro.
- Defective Product: Mounjaro’s propensity to cause severe side effects, such as gastroparesis may make it inherently defective.
- Breach of Warranty: Some plaintiffs argue that Mounjaro did not work as advertised or guaranteed.
Current Status of Mounjaro Litigation
As of 2024, Mounjaro lawsuits are still in the early stages. Many individual cases have been filed in various state and federal courts across the United States.
Some federal court cases, along with other GLP-1 lawsuits against Ozempic, Wegovy, Rybelsus, and Trulicity, are consolidating into multidistrict litigation (MDL) in Pennsylvania.
