JANUMET (JAN-you-met) tablets contain 2 prescription medicines: sitagliptin (JANUVIA®) and metformin. JANUMET can be used along with diet and exercise to lower blood sugar in adults with type 2 diabetes. Your doctor will determine whether JANUMET is right for you.

JANUMET should not be used in patients with type 1 diabetes or with diabetic ketoacidosis (increased ketones in the blood or urine). If you have had pancreatitis (inflammation of the pancreas), it is not known if you have a higher chance of getting it while taking JANUMET.

Selected Risk Information About JANUMET
Metformin, one of the ingredients in JANUMET, can cause a rare but serious side effect called lactic acidosis (a buildup of lactic acid in the blood), which can cause death. Lactic acidosis is a medical emergency that must be treated in a hospital. Stop taking JANUMET and call your doctor right away if you get any of the following symptoms of lactic acidosis: you feel very weak or tired; have unusual (not normal) muscle pain; have trouble breathing; have unusual sleepiness or sleep longer than usual; have sudden stomach or intestinal problems with nausea and vomiting or diarrhea; feel cold, especially in your arms and legs; feel dizzy or lightheaded; or have a slow or irregular heartbeat.

You have a higher chance of getting lactic acidosis if you have kidney problems, liver problems, or congestive heart failure that requires treatment with medicine; if you drink alcohol very often, drink a lot of alcohol in a short period of time, or get dehydrated (lose large amounts of body fluids); if you have certain x-ray tests with dyes or contrast agents that are injected into your body; if you have surgery, a heart attack, severe infection, or stroke; or if you are 80 years or older and have not had your kidneys tested.

Pancreatitis is another serious side effect that can happen in people taking JANUMET. Pancreatitis may be severe and lead to death. Before you start taking JANUMET, tell your doctor if you’ve ever had pancreatitis. Stop taking JANUMET and call your doctor right away if you have pain in your stomach area (abdomen) that is severe and will not go away. The pain may be felt going from your abdomen through to your back. The pain may happen with or without vomiting. These may be symptoms of pancreatitis.

Do not take JANUMET if you are allergic to any of the ingredients in JANUMET. Allergic reactions, which may be serious, including rash; hives; and swelling of the face, lips, tongue, and throat that may cause difficulty breathing or swallowing, can occur. If you have an allergic reaction, stop taking JANUMET and call your doctor right away.

Do not take JANUMET if you are going to receive an injection of dye or contrast agent for an x-ray procedure or if your kidneys are not working properly. Your doctor will do blood tests before and during your treatment with JANUMET to see how well your kidneys are working.

If you take JANUMET with another medicine that can cause low blood sugar (hypoglycemia), such as a sulfonylurea or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea or insulin may need to be lowered. Signs and symptoms of low blood sugar may include headache, drowsiness, weakness, dizziness, confusion, irritability, hunger, fast heart beat, sweating, and feeling jittery.

Kidney problems, sometimes requiring dialysis, have been reported.

Common side effects when taking JANUMET include stuffy or runny nose and sore throat, upper respiratory tract infection, diarrhea, nausea and vomiting, gas, upset stomach, indigestion, weakness, and headache.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit, or call 1-800-FDA-1088.

Please read the Medication Guide, including the information about lactic acidosis, and discuss it with your doctor. The physician Prescribing Information also is available.
