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.
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:
- 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 unusual sleepiness or sleep longer than usual
- you have stomach pains, nausea, or vomiting
- 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.
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:
- inflammation of your pancreas (pancreatitis)
- stones in your gallbladder (gallstones)
- a history of alcoholism
- high blood triglyceride levels
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:
- 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
- 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:
- have low blood pressure
- take medicines to lower your blood pressure, including water pills (diuretics)
- are 65 years of age or older
- are on a low salt diet
- have kidney problems

- Ketoacidosis (increased ketones in your blood or urine). Ketoacidosis has happened in people who have type 1 diabetes or type 2 diabetes, during treatment with dapagliflozin, one of the medicines in Qternmet XR. Ketoacidosis is a serious condition, which may need to be treated in a hospital. Ketoacidosis may lead to death. Ketoacidosis can happen with dapagliflozin even if your blood sugar is less than 250 mg/dL.
Stop taking Qternmet XR and call your healthcare provider right away if you get any of the following symptoms:
- trouble breathing
- stomach area (abdominal) pain
- Kidney problems. Sudden kidney injury has happened to people taking dapagliflozin. Talk to your healthcare provider right away if you:

- you start to lose liquids from your body with vomiting, diarrhea, or being in the sun too long.
- Serious urinary tract infections. Serious urinary tract infections that may lead to hospitalization have happened in people who are taking dapagliflozin. 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. Tell your healthcare provider if you take other diabetes medicines. Signs and symptoms of low blood sugar may include:
- shaking or feeling jittery
- change in mood
- rapid heartbeat
- change in vision
- A rare but serious bacterial infection that causes damage to the tissue under the skin (necrotizing fasciitis) in the area between and around the anus and genitals (perineum). Necrotizing fasciitis of the perineum has happened in women and men who take dapagliflozin, one of the medicines in Qternmet XR. Necrotizing fasciitis of the perineum may lead to hospitalization, may require multiple surgeries and may lead to death. Seek medical attention immediately if you have fever or you are feeling very weak, tired or uncomfortable (malaise) and you develop any of the following symptoms in the area between and around the anus and genitals:
- pain or tenderness
- redness of skin (erythema)
- Serious allergic reaction. Qternmet XR may cause serious allergic reactions. Stop taking Qternmet XR and get medical help right away if you develop any of the following symptoms of a serious allergic reaction including:

- difficulty with swallowing or breathing
- skin rash, itching, flaking, or peeling
- raised red patches on your skin (hives)
- Low vitamin B12 (vitamin B12 deficiency). Using metformin for long periods of time may cause a decrease in the amount of vitamin B12 in your blood, especially if you have had low vitamin B12 levels before. Your healthcare provider may do blood tests to check your vitamin B12 levels.
- Vaginal yeast infection. Women who take Qternmet XR may get vaginal yeast infections. Symptoms of a vaginal yeast infection include:
- vaginal odor
- white or yellowish vaginal discharge (discharge may be lumpy or look like cottage cheese)
- vaginal itching
- Yeast infection of the penis (balanitis). Men who take Qternmet XR may get a yeast infection of the skin around the penis. Certain men who are not circumcised may have swelling of the penis that makes it difficult to pull back the skin around the tip of the penis. Other symptoms of a yeast infection of the penis include:
- redness, itching, or swelling of the penis
- rash of the penis
- foul smelling discharge from the penis
- pain in the skin around the penis
- Increased fats in your blood (bad cholesterol or LDL).
- Bladder cancer. In studies of dapagliflozin in people with diabetes, bladder cancer occurred in a few more people who were taking dapagliflozin than in people who were taking other diabetes medicines. There were too few cases to know if bladder cancer was related to dapagliflozin. You should not take Qternmet XR if you have bladder cancer. Tell your healthcare provider right away if you have any of the following symptoms:
- blood or a red color in your urine
- pain while you urinate
