GLP-1s are contraindicated in individuals with a history of medullary thyroid carcinoma, a family history of such, or in patients with multiple endocrine neoplasia syndrome type 2. Do not take them if you have ever had thyroid cancer. In studies with rodents, GLP-1s caused thyroid tumors, including thyroid cancer; it is not known if they will cause thyroid tumors or cancer in humans. Please notify your doctor ASAP if you develop trouble swallowing, hoarseness, a lump or swelling in your neck, or shortness of breath. 

If you experience a medical emergency, call 911 or go to the nearest emergency room.

• Pancreatitis: Severe pain in your abdomen or back that will not go away
