This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised: 12/2020
Medication GuideJANUMET® XR (JAN-you-met XR)(sitagliptin and metformin hydrochloride extended-release)tablets, for oral use
Read this Medication Guide carefully before you start taking JANUMET XR and each time you get a refill. There may be new information. This information does not take the place of talking with your doctor about your medical condition or your treatment. If you have any questions about JANUMET XR, ask your doctor or pharmacist.
What is the most important information I should know about JANUMET XR?JANUMET XR can cause serious side effects, including:
1.
Lactic Acidosis. Metformin, one of the medicines in JANUMET XR, can cause a rare but serious condition called lactic acidosis (a buildup of an acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in the hospital.

Stop taking JANUMET XR and call your doctor right away if you have any of the following symptoms, which could be signs of lactic acidosis:

  • you feel cold in your hands or feet
  • you feel dizzy or lightheaded
  • you have a slow or irregular heartbeat
  • you feel very weak or tired
  • you have unusual (not normal) muscle pain
  • you have trouble breathing
  • you feel sleepy or drowsy
  • you have stomach pains, nausea or vomiting

Most people who have had lactic acidosis with metformin have other things that, combined with the metformin, led to the lactic acidosis. Tell your doctor if you have any of the following, because you have a higher chance for getting lactic acidosis with JANUMET XR if you:

  • have severe kidney problems or your kidneys are affected by certain x-ray tests that use injectable dye
  • have liver problems
  • drink alcohol very often, or drink a lot of alcohol in short-term “binge” drinking
  • get dehydrated (lose a large amount of body fluids). This can happen if you are sick with a fever, vomiting, or diarrhea. Dehydration can also happen when you sweat a lot with activity or exercise and do not drink enough fluids.
  • have surgery
  • have a heart attack, severe infection, or stroke
  • are 65 years of age or older

The best way to keep from having a problem with lactic acidosis from metformin is to tell your doctor if you have any of the problems in the list above. Your doctor may decide to stop your JANUMET XR for a while if you have any of these things.

JANUMET XR can have other serious side effects. See What are the possible side effects of JANUMET XR?

2.

  • pancreatitis
  • stones in your gallbladder (gallstones)
  • a history of alcoholism
  • high blood triglyceride levels

Stop taking JANUMET XR 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.

3.
Heart failure. Heart failure means that your heart does not pump blood well enough.
Before you start taking JANUMET XR, tell your doctor if you have ever had heart failure or have problems with your kidneys. Contact your doctor right away if you have any of the following symptoms:
  • increasing shortness of breath or trouble breathing, especially when you lie down
  • swelling or fluid retention, especially in the feet, ankles or legs
  • an unusually fast increase in weight
  • unusual tiredness
These may be symptoms of heart failure.
