Is Zepbound Safe to Take?

Zepbound is an obesity medication manufactured by the Eli Lilly Company. It is approved to treat overweight adults with at least one weight-related health issue like high cholesterol, hypertension or type 2 diabetes. The U.S. Food and Drug Administration (FDA) approved Zepbound for weight loss in November 2023.

Zepbound is a self-injected medication used once a week. It stimulates hormones that regulate blood sugar levels to reduce appetite. Zepbound also makes people feel fuller by making the stomach empty slower, which can lead to weight loss. 

Tirzepatide is the active ingredient in both Zepbound and Mounjaro®, another drug made by Eli Lilly. Zepbound is approved for weight loss, while Mounjaro is used to manage type 2 diabetes. Tirzepatide is intended to be used with diet and exercise to control either condition. 

Zepbound has numerous safety concerns. The medication may be linked to severe gastrointestinal issues like ileus, intestinal blockages and gastroparesis. It may also be linked to thyroid C-cell tumors, including medullary thyroid carcinoma (MTC). Zepbound should not be used by pregnant women or people who have multiple endocrine neoplasia syndrome type 2.

Other drugs in its class have also been linked to vision loss, pulmonary aspiration and blood clots leading to pulmonary embolism.

Other common side effects associated with Zepbound use include:

• Constipation
• Diarrhea
• Loss of appetite
• Nausea
• Vomiting

Zepbound can cause these and other gastrointestinal side effects. If you lose weight on the medication, you might need to take it indefinitely to keep from regaining lost weight.

Zepbound safety concerns on its warning label

Multiple Zepbound safety concerns are listed on its warning label, including thyroid tumors and thyroid cancer. Studies have found that Zepbound causes these conditions in rats.

Unlisted safety concerns about Zepbound

Unlisted safety concerns about Zepbound have also prompted lawsuits against Eli Lilly. These alleged Zepbound risks include:

• Deep vein thrombosis (DVT): A blood clot forms in the deep veins in the body, typically in the legs, and may cause pain, swelling, warmth and tenderness in the leg. DVT can be severe if the blood clots in the legs break loose, travel to the lungs and obstruct blood flow.
• Gastroparesis: Sometimes called delayed gastric emptying or stomach paralysis, gastroparesis slows or stops food from moving from the stomach to the small intestine, even when there is no blockage. Symptoms of gastroparesis include feeling full well after eating a meal, having nausea and vomiting.
• Ileus: A partial or complete intestinal obstruction that temporarily prevents food and waste from moving through the digestive tract. Ileus can be caused by health issues, infection, injury, surgery or medications. Symptoms include bloating, constipation, cramps, dehydration, loss of appetite, nausea, watery stools and vomiting.
• Vision loss: People with diabetic retinopathy might experience a temporary worsening of vision when they begin to use Zepbound or when they start taking a higher dosage. Diabetic retinopathy is an eye disease that develops when high blood sugar levels cut off blood flow to the retina, potentially causing permanent blindness.

The safety concerns about Zepbound have led to legal action against Eli Lilly. People who have suffered from these and other serious conditions have started filing Zepbound lawsuits.
