Qtern

What is Qtern?

Qtern is a prescription medicine that contains dapagliflozin and saxagliptin. Qtern is used along with diet and exercise to improve blood sugar (glucose) control in adults with type 2 diabetes.

• Qtern is not for people with type 1 diabetes. Qtern may increase the risk of diabetic ketoacidosis (increased ketones in your blood or urine) in people with type 1 diabetes.
• It is not known if Qtern is safe and effective in children younger than 18 years of age.

What is the most important information I should know about Qtern?

Serious side effects can happen to people taking Qtern, including:

• Inflammation of the pancreas (pancreatitis). Saxagliptin, one of the medicines in Qtern, 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 taking Qtern, 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
  It is not known if having these medical problems will make you more likely to get pancreatitis with Qtern.
  Stop taking Qtern 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 taking Qtern, 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
  These may be symptoms of heart failure.
• Ketoacidosis (increased ketones in your blood or urine). Ketoacidosis has happened in people who have type 1 or type 2 diabetes, during treatment with dapagliflozin, one of the medicines in Qtern. Ketoacidosis has also happened in people with diabetes who were sick or who had surgery during treatment with dapagliflozin. 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 Qtern and call your healthcare provider right away if you get any of the following symptoms:
  • nausea
  • tiredness
  • vomiting
  • trouble breathing
  • stomach area (abdominal) pain
  If you get any of these symptoms during treatment with Qtern, if possible check for ketones in your urine, even if your blood sugar is less than 250 mg/dL.
• Dehydration. Qtern 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). There have been reports of sudden kidney injury in people with Type 2 diabetes who are taking dapagliflozin, a component of Qtern. You may be at a higher risk of dehydration if you:
  • 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
  Talk to your healthcare provider about what you can do to prevent dehydration including how much fluid you should drink on a daily basis. Call your healthcare provider right away if you reduce the amount of food or liquid you drink, for example if you cannot eat or you start to lose liquids from your body, for example from vomiting, diarrhea, or being in the sun too long.

  • swelling of the face, lips, throat and other areas of your skin
  • difficulty with swallowing or breathing

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

  • redness, itching, or swelling of the penis
  • rash of the penis
  • foul smelling discharge from the penis
  • 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.
