Xultophy® 100/3.6 may cause serious side effects that can be life-threatening, including:
- inflammation of your pancreas (pancreatitis). Stop using Xultophy® 100/3.6 and call your health care provider right away if you have severe pain in your stomach area (abdomen) that will not go away, with or without vomiting. You may feel the pain from your abdomen to your back.
- low blood sugar (hypoglycemia). Your risk for getting low blood sugar may be higher if you use Xultophy® 100/3.6 with another medication that can cause low blood sugar. Signs and symptoms of low blood sugar may include: shakiness, irritability, fast heartbeat, dizziness, weakness, sweating, confusion, drowsiness, hunger, headache, and feeling jittery.
- kidney problems (kidney failure). Worsening of kidney failure and sudden kidney failure have happened in people with kidney problems and in people without kidney problems, who have taken liraglutide, one of the ingredients in Xultophy® 100/3.6. Diarrhea, nausea, and vomiting may cause a loss of fluids (dehydration) which may cause kidney problems to get worse. Tell your health care provider if you have diarrhea, nausea, or vomiting. Drink plenty of fluids to help reduce your risk of dehydration during treatment with Xultophy® 100/3.6.
- serious allergic reactions. Stop using Xultophy® 100/3.6 and get medical help right away if you have any symptoms of a serious allergic reaction, including swelling of your face, lips, tongue or throat, problems breathing or swallowing, sudden coughing, chest pain or tightness, hives, rash, itching, fast heartbeat, or fainting or feeling dizzy.

Tell your health care provider right away if you get symptoms of gallbladder problems including pain in the right or middle upper stomach area, fever, yellowing of skin or eyes (jaundice), or clay-colored stools.
- low potassium in your blood (hypokalemia).
- heart failure. Taking certain diabetes medicines called TZDs with Xultophy® 100/3.6 may cause heart failure in some people. This can happen even if you have never had heart failure or heart problems. If you already have heart failure, it may get worse while you take TZDs with Xultophy® 100/3.6. Tell your health care provider if you have any new or worse symptoms of heart failure, including shortness of breath, tiredness, swelling of your ankles or feet, and sudden weight gain.
