XIGDUO XR Frequently Asked Questions

What is the most important information I should know about XIGDUO (zig-DOO-oh) XR?

XIGDUO XR can cause serious side effects, including lactic acidosis. Metformin, one of the medicines in XIGDUO XR, can cause a rare, but serious, side effect called lactic acidosis (a build-up of lactic acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in a hospital.

Stop taking XIGDUO XR and 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 very weak or tired
  • you have unusual (not normal) muscle pain
  • you have trouble breathing
  • you have unusual sleepiness or sleep longer than usual
  • you have stomach pains, nausea, or vomiting
  • you feel dizzy or lightheaded
  • you have a slow or irregular heartbeat

You have a higher chance of getting lactic acidosis with XIGDUO XR if you:

  • have severe kidney problems
  • have kidneys that 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

Who should not take XIGDUO XR?

Do not take XIGDUO XR if you:

  • have moderate to severe kidney problems or are on dialysis
  • are allergic to dapagliflozin, metformin, or any of the ingredients in XIGDUO XR. See below for a list of ingredients in XIGDUO XR. Symptoms of a serious allergic reaction may include:
    • skin rash
    • raised red patches on your skin (hives)
    • swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing
  • If you have any of these symptoms, stop taking XIGDUO XR and contact your healthcare provider or go to the nearest hospital emergency room right away.

  • have a condition called metabolic acidosis or diabetic ketoacidosis (increased ketones in your blood or urine)

What are the possible side effects of XIGDUO XR?

XIGDUO XR may cause serious side effects including:

See “What is the most important information I should know about XIGDUO XR?”

  • dehydration. XIGDUO XR can cause some people to have dehydration (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

    Talk to your doctor about what you can do to prevent dehydration.

  • ketoacidosis (increased ketones in your blood or urine). Ketoacidosis occurred in people with type 1 and type 2 diabetes during treatment with dapagliflozin, one of the medicines in XIGDUO XR. Ketoacidosis is a serious condition which may require hospitalization and may lead to death. Ketoacidosis can happen with XIGDUO XR even if your blood sugar is less than 250 mg/dL. Stop taking XIGDUO XR and call your doctor right away if you get any of the following symptoms:
    • nausea
    • vomiting
    • stomach area (abdominal) pain
    • tiredness
    • trouble breathing

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

  • kidney problems. Sudden kidney injury occurred in people taking XIGDUO XR. Talk to your doctor right away if you reduce the amount you eat or drink, or if you lose liquids; for example, from vomiting, diarrhea, or excessive heat exposure
  • serious urinary tract infections. Serious urinary tract infections, some that lead to hospitalization, occurred in people taking dapagliflozin, one of the medicines in XIGDUO XR. Tell your doctor 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 XIGDUO XR with another medicine that can cause low blood sugar, such as sulfonylureas or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea medicine or insulin may need to be lowered while you take XIGDUO XR. Signs and symptoms of low blood sugar may include:
    • headache
    • confusion
    • shaking or feeling jittery
    • drowsiness
    • dizziness
    • weakness
    • irritability
    • sweating
    • hunger
    • fast heartbeat
  • 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 XIGDUO 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 XIGDUO 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 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

    Talk to your healthcare provider about what to do if you get symptoms of a yeast infection of the vagina or penis. Your healthcare provider may suggest you use an over-the-counter antifungal medicine. Talk to your healthcare provider right away if you use an over-the-counter antifungal medication and your symptoms do not go away.

  • 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 medications. There were too few cases to know if bladder cancer was related to dapagliflozin. You should not take XIGDUO 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

The most common side effects of XIGDUO XR include:

  • vaginal yeast infections and yeast infections of the penis
