Read this Medication Guide before you start treatment. This information does not take the place of talking with your healthcare provider about your medical condition or your treatment.
Important information
Serious side effects can happen to people taking Qternmet XR, including:
· Lactic Acidosis. Metformin, one of the medicines in Qternmet XR, can cause a rare but serious condition called lactic acidosis (a build-up of an acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in the hospital.
Call your healthcare provider right away if you have any of the following symptoms, which could be signs of lactic acidosis:
o you feel cold in your hands or feet
o you feel dizzy or lightheaded
o you have a slow or irregular heartbeat
o you feel very weak or tired
o you have unusual (not normal) muscle pain
o you have trouble breathing
o you feel unusual sleepiness or sleep longer than usual
o you have stomach pains, nausea, or vomiting
Most people who have had lactic acidosis with metformin have other things that, combined with the metformin use, led to the lactic acidosis. Tell your healthcare provider if you have any of the following, because you have a higher chance for getting lactic acidosis with Qternmet XR if you:
o have severe kidney problems or your kidneys are affected by certain x-ray tests that use injectable dye
o have liver problems
o drink alcohol very often, or drink a lot of alcohol in short-term "binge" drinking
o 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.
o have surgery
o have a heart attack, severe infection, or stroke.
The best way to keep from having a problem with lactic acidosis from metformin is to tell your healthcare provider if you have any of the problems in the list above. Your healthcare provider may decide to stop your Qternmet XR for a while if you have any of these problems.
· Inflammation of the pancreas (pancreatitis). Saxagliptin, one of the medicines in Qternmet XR, can cause inflammation of the pancreas, which may be severe and lead to death. Certain medical problems make you more likely to get pancreatitis.
Before you start treatment, tell your healthcare provider if you have ever had:
o inflammation of your pancreas (pancreatitis)
o stones in your gallbladder (gallstones)
o a history of alcoholism
o high blood triglyceride levels
It is not known if having these medical problems will make you more likely to get pancreatitis with Qternmet XR.
Stop taking Qternmet XR and contact your healthcare provider 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.
· Heart failure. Heart failure means your heart does not pump blood well enough. Before you start treatment, tell your healthcare provider if you have ever had heart failure or have problems with your kidneys.
Contact your healthcare provider right away if you have any of the following symptoms:
o increasing shortness of breath or trouble breathing, especially when you lie down
o swelling or fluid retention, especially in the feet, ankles, or legs
o an unusually fast increase in weight
o unusual tiredness
These may be symptoms of heart failure.
· Dehydration. Qternmet XR can cause some people to become dehydrated (the loss of body water and salt). Dehydration may cause you to feel dizzy, faint, lightheaded, or weak, especially when you stand up (orthostatic hypotension). You may be at a higher risk of dehydration if you:
o have low blood pressure
o take medicines to lower your blood pressure, including water pills (diuretics)
o are 65 years of age or older
o are on a low salt diet
o have kidney problems
Qternmet XR can have other serious side effects. See Qternmet XR side effects.

If you get any of these symptoms during your treatment, if possible check for ketones in your urine, even if your blood sugar is less than 250 mg/dL.

Tell your healthcare provider if you have any signs or symptoms of a urinary tract infection such as a burning feeling when passing urine, a need to urinate often, the need to urinate right away, pain in the lower part of your stomach (pelvis), or blood in the urine. Sometimes people also may have a fever, back pain, nausea or vomiting.
· Low blood sugar (hypoglycemia). If you take Qternmet XR with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin, this can increase your risk of getting low blood sugar.

o shaking or feeling jittery
o hunger
o change in mood
o sweating
o headache
o confusion
o rapid heartbeat

Necrotizing fasciitis of the perineum may lead to hospitalization, may require multiple surgeries and may lead to death.

· Vaginal yeast infection. Women who take Qternmet XR may get vaginal yeast infections. Symptoms of a vaginal yeast infection include:
o vaginal odor
o white or yellowish vaginal discharge (discharge may be lumpy or look like cottage cheese)
o vaginal itching

o redness, itching, or swelling of the penis
o rash of the penis
o foul smelling discharge from the penis
o pain in the skin around the penis
Talk to your healthcare provider about what to do if you get symptoms of a yeast infection of the vagina or penis.
