Qtern

Generic Name: dapagliflozin and saxagliptin (DAP a gli FLOE zin and SAX a GLIP tin)
Brand Names: Qtern

What is Qtern?

Qtern contains a combination of dapagliflozin and saxagliptin. Dapagliflozin and saxagliptin are oral diabetes medicines that help control blood sugar levels. Dapagliflozin works by helping the kidneys get rid of glucose from your bloodstream. Saxagliptin works by regulating the levels of insulin your body produces after eating.

Qtern is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus.

Qtern is also used to lower the risk of death from heart attack, stroke, or heart failure in adults with type 2 diabetes who also have heart disease.

This medicine is not for treating type 1 diabetes.

Important information

You should not use Qtern if you have severe kidney disease, if you are on dialysis, or if you have diabetic ketoacidosis.

Taking Qtern can make you dehydrated, which could cause you to feel weak or dizzy (especially when you stand up).

Stop taking Qtern and call your doctor at once if you have signs of a pancreatitis, such as severe pain in your upper stomach spreading to your back, with or without vomiting.

Qtern can also cause infections in the bladder or genitals (penis or vagina). Call your doctor if you have genital pain or itching, genital odor or discharge, increased urination, pain or burning when you urinate, or blood in your urine.

Some people taking dapagliflozin have had bladder cancer, but it is not clear if this medicine was the actual cause.

Before taking this medicine

You should not use Qtern if you are allergic to dapagliflozin and saxagliptin, or if you have:

  • severe kidney disease (or if you are on dialysis);

  • a history of severe allergic or skin reaction after taking dapagliflozin or saxagliptin; or

  • diabetic ketoacidosis (call your doctor for treatment with insulin).

To make sure Qtern is safe for you, tell your doctor if you have ever had:

  • kidney disease;

  • liver disease;

  • bladder cancer;

  • a bladder infection;

  • problems with your pancreas, including surgery;

  • gallstones;

  • high cholesterol or triglycerides (a type of fat in the blood);

  • alcoholism;

  • if you are on a low salt diet; or

  • if you are 65 or older.

It is not known whether Qtern will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether dapagliflozin and saxagliptin passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How should I take Qtern?

Qtern is usually taken once per day in the morning. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

You may take this medicine with or without food.

Call your doctor if you are sick with vomiting or diarrhea, if you consume less food or fluid than usual, or if you are sweating more than usual.

Your blood sugar will need to be checked often, and you may also need to test the level of ketones your urine. Dapagliflozin can cause life-threatening ketoacidosis (too much acid in the blood). Even if your blood sugar is normal, contact your doctor if a urine test shows that you have ketones in the urine.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.

Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.

This medicine can cause unusual results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using Qtern.

Store Qtern at room temperature away from moisture and heat.
