Congestive Heart Failure (CHF): Congestive heart failure can increase the risk of lactic acidosis caused by metformin. For this reason, Janumet is not recommended for people with CHF. If you have CHF, speak to your doctor.
Diabetes complications: The use of Janumet will not prevent the development of complications of diabetes mellitus (e.g., kidney disease, nerve disease, eye disease).
Dye or contrast agents: If you are going to have an X-ray procedure that uses dye or a contrast agent, you may need to stop taking Janumet for a short time. Contact your doctor for instructions.

People with severe kidney disease, heart failure, or dehydration are at higher risk of developing lactic acidosis. Since alcohol may increase the risk of lactic acidosis, do not drink a lot of alcohol over the short or long term while taking Janumet. When it does occur (very rarely), it is fatal in 50% of cases. If you experience symptoms of lactic acidosis (e.g., weakness; tiredness; drowsiness; unusual muscle pain; trouble breathing; stomach pain with nausea, vomiting, or diarrhea; feeling cold; dizziness; lightheadedness; slow or irregular heartbeat), stop taking Janumet and get immediate medical attention.
Liver function: Janumet is not recommended for people with severely reduced liver function. If you have moderately reduced liver function, discuss with your doctor how Janumet may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Janumet, and whether any special monitoring is needed.
Low blood glucose: Low blood glucose can occur when sitagliptin – metformin is used in combination with other medications to treat diabetes. Low blood glucose may also occur when not enough food is eaten, especially when strenuous exercise is undertaken at the same time or when large amounts of alcohol have been consumed. If you experience low blood sugar (e.g., headache, drowsiness, weakness, dizziness, confusion, irritability, hunger, fast heartbeat, sweating, and feeling jittery) while taking Janumet, contact your doctor.
Pancreatitis: Janumet may cause pancreatitis (inflammation of the pancreas). If you have a history of pancreatitis, gallstones, Alcoholism, or high triglycerides you may be more at risk of experiencing this. If you experience prolonged and severe abdominal pain with or without vomiting while taking Janumet, contact your doctor immediately.
Reduced response: Over a period of time, people may become progressively less responsive to a particular treatment for diabetes because their diabetes worsens. If your blood glucose control worsens or you are not staying within your target levels, talk to your doctor.
Surgery: Janumet should be stopped temporarily for surgery (except for minor surgery where food and fluid intake is not restricted). You will be restarted on Janumet once you are eating and drinking and your kidney function has been tested and is normal. Talk to your doctor for specific instructions.
Thyroid function: People with low thyroid function may develop further decreases in the function of their thyroid. Symptoms of these changes include feeling cold all the time, weight gain, fatigue, dry skin, and decreased memory and concentration. Contact your doctor if you experience these symptoms.
Vitamin B12 levels: Janumet may decrease vitamin B12 levels. Your doctor will monitor your B12 levels with blood tests while you are taking Janumet.
Pregnancy: Janumet is not recommended for use during pregnancy or for women who are planning to become pregnant. If you become pregnant while taking Janumet, contact your doctor immediately. Insulin is usually used during pregnancy to control blood glucose levels.
