The common side effects of Mounjaro (tirzepatide) include nausea, vomiting, diarrhea, constipation, stomach discomfort, heartburn, burping, excess wind, itching, rash, injection site reactions, low blood pressure, and hair loss. These side effects usually improve as the body adjusts to the medication. Some people with type 2 diabetes might experience low blood sugar (hypoglycemia) if taking Mounjaro alongside other diabetes medications, with symptoms like dizziness, tiredness, hunger, weakness, confusion, irritability, anxiety, fast heartbeat, and sweating. Less common but more serious side effects can include gallbladder problems (gallstones or inflammation), pancreatitis (inflammation of the pancreas) causing severe stomach or back pain, and allergic reactions such as swelling of the face, tongue, or throat, difficulty breathing, severe rash, or angioedema (skin swelling mostly around eyes and mouth). There is also a warning about potential thyroid tumors from animal studies, and rare cases of stomach paralysis (gastroparesis) have been reported. If any severe side effects like intense stomach pain, jaundice, severe allergic reactions, or signs of pancreatitis occur, medical help should be sought immediately. Reporting side effects to a healthcare professional is important for safe management. In summary, common side effects are mainly digestive (nausea, vomiting, diarrhea, constipation), injection site reactions, and low blood sugar risks if combined with other diabetes drugs. Serious but rare side effects include pancreatitis, gallbladder issues, allergic reactions, and possible thyroid concerns.
