What side effects and warning signs should I watch for with semaglutide?
Short answer
Common semaglutide side effects include nausea, vomiting, diarrhea, constipation, and stomach pain. Contact your care team if symptoms persist or limit eating or drinking. Seek urgent care for severe, lasting belly pain or dehydration. Call 911 for trouble breathing or swelling of your face, lips, tongue, or throat.
Stomach-related side effects are common with semaglutide, especially when treatment starts or the dose increases. These can include nausea, vomiting, diarrhea, constipation, bloating, and stomach pain. Tell your care team if symptoms interfere with daily life, eating, or drinking. Do not raise your dose while waiting for advice.
Severe, lasting belly pain, especially pain that spreads to your back, needs urgent medical evaluation because it may signal pancreatitis. Upper belly pain with fever, yellow skin or eyes, or pale stools may signal a gallbladder problem. Repeated vomiting, dizziness, or very little urine can be signs of dehydration and possible kidney problems.
Call 911 for trouble breathing, fainting, or swelling of the face, lips, tongue, or throat. Report new vision changes promptly, especially if you have diabetes.
Semaglutide carries a warning about thyroid C-cell tumors seen in animal studies. It is not known whether it causes these tumors in humans. Report a neck lump, lasting hoarseness, or trouble swallowing. A licensed physician in your state can explain how these risks apply to you.
