Janumet is a combination of Type 2 diabetes medications used to control blood sugar levels. It contains metformin, which decreases glucose production and absorption in the body, and sitagliptin to regulate insulin levels.

Janumet is not prescribed for Type 1 diabetes.

Always follow your doctor’s instructions and use Janumet exactly as prescribed.

• Take with food.
• Swallow tablet whole. Do not crush, break or chew.
• Watch for signs of low blood sugar (headache, nausea, irritability, dizziness, shaking), and always keep a source of sugar with you (fruit juice, hard candy, glucose tablets).

Do not use Janumet if you have kidney disease or diabetic ketoacidosis.

Janumet can cause lactic acidosis, a serious condition that requires emergency medical help. Signs include trouble breathing, numb or cold arms and legs, stomach pain, muscle pain or weakness, nausea with vomiting, slow heart rate, dizziness, fatigue.

Before taking Janumet, inform your doctor if you have any of the following:

• Kidney, liver or heart disease
• Gallstones
• High triglycerides
• Pancreatitis
• Alcoholism

Common side effects of Janumet include:

• Nausea, diarrhea, gas, vomiting
• Runny nose, sneezing, sore throat
• Headache
• Weakness

Contact your doctor if you experience these more serious side effects:

• Blisters or itching
• Severe joint pain
• Producing little or no urine
• Heart failure symptoms – swelling in legs and feet, rapid weight gain, shortness of breath
• Symptoms of lactic acidosis – muscle pain, nausea with vomiting, irregular heart rate, stomach pain, trouble breathing, feeling cold, dizzy, light-headed or weak

Can I take Janumet if I have Type 1 diabetes?

No. Janumet is specifically for patients with Type 2 diabetes, and should only be taken under the care of a doctor.

How long will I need to take Janumet?

Continue taking Janumet as directed by your doctor. Lifestyle changes including diet and exercise can help better control your diabetes, and may reduce the need to take Janumet.
