About this Medication

What the medication is used for:

XIGDUO is used along with diet and exercise in adults with type 2 diabetes to help control their blood sugar levels. XIGDUO can be used:

  • in patients taking dapagliflozin (FORXIGA) and metformin as separate tablets, or
  • in patients taking dapagliflozin (FORXIGA), metformin and insulin.

What it does:

XIGDUO contains dapagliflozin and metformin hydrochloride.

Dapagliflozin removes excess glucose from the body through the urine.

Metformin helps your body respond better to the insulin it makes naturally. It helps to lower the amount of sugar made by the liver and lower the amount of sugar moved from the gut into the blood.

When it should not be used:

Do not take XIGDUO if you:

  • have unstable and/or insulin-dependent (Type I) diabetes mellitus.
  • have increased ketones in the blood or urine (metabolic acidosis or diabetic ketoacidosis) or have had ketoacidosis with or without coma.
  • have a history of too much acid in the blood (lactic acidosis).
  • have or ever had kidney or liver problems.
  • consume large amounts of alcohol all the time or shortterm ‘binge’.
  • have heart failure or other severe heart problems.
  • are stressed, have a serious infection, have recently had a trauma, are about to have surgery or are recovering from surgery.
  • are dehydrated (have lost a lot of water from your body).
  • are allergic (hypersensitive) to dapagliflozin, metformin hydrochloride or any of the ingredients listed below.
  • have bladder cancer.
  • take pioglitazone, a drug to reduce the amount of sugar in the blood.
  • are pregnant or planning to become pregnant; it is not known if XIGDUO will harm your unborn baby. Talk with your doctor about the best way to control your blood sugar while you are pregnant.
  • are breast-feeding or plan to breast-feed; it is not known if XIGDUO will pass into your breast milk. Talk to your doctor if you would like to breast feed.
  • will have certain x-ray tests with injectable dyes or contrast agents. Talk to your physician or pharmacist about when to stop XIGDUO and when to start again.

Warnings and Precautions

Serious Warnings and Precautions
XIGDUO contains metformin and it can rarely cause a serious condition that can cause death called lactic acidosis. Alcohol may increase the risk of lactic acidosis. Do not drink a lot of alcohol while taking XIGDUO (see Lactic Acidosis section below).

Lactic Acidosis

Stop taking XIGDUO and tell your doctor if you get the following symptoms of lactic acidosis:

  • You feel very weak and tired.
  • You have unusual (not normal) muscle pain.
  • You have trouble breathing or fast breathing.
  • You have stomach pain with nausea and vomiting, or diarrhea.
  • You feel cold, especially in your arms and legs.
  • You feel dizzy or lightheaded.
  • You feel unusual fatigue and drowsiness.
  • You have a slow or irregular heart beat.
  • Your medical condition suddenly changes.
  • You develop or experience a worsening of heart problems and particularly heart failure.

BEFORE you use XIGDUO talk to your doctor or pharmacist if you:

  • are older than 65 years of age.
  • are dehydrated (have lost 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 don’t drink enough fluids.
  • have heart problems or low blood pressure.
  • are taking medicines for high blood pressure or taking a water pill (used to remove excess water from the body).
  • are taking medicines to lower blood sugar such as glyburide, gliclazide or glimepiride (sulfonylureas) or insulin. Taking XIGDUO with any of these medications can increase the risk of having low blood sugar (hypoglycemia).
  • have a problem with your adrenal glands (found on top of your kidneys) or pituitary gland (found in your brain).
  • have a history of bladder cancer.
  • will be having surgery.
  • have had a heart attack, severe infection, or stroke.
  • feel very weak and tired.
  • are 80 years of age or older and have not had your kidney function tested.
  • have low B12 levels.
  • have had an allergic reaction to SGLT2 inhibitors (used to treat Type 2 diabetes).

XIGDUO is not recommended for use in patients under 18 years of age.

XIGDUO will cause your urine to test positive for sugar (glucose).

XIGDUO may cause changes in the amount of cholesterol or fats in your blood.

XIGDUO increases the chance of getting a yeast infection of the penis or vagina. This is more likely in people who have had yeast infections in the past.

Driving and using machines: XIGDUO may cause dizziness or lightheaded-ness. Do not drive or use machines until you know how the medicine affects you.

Interactions with this Medication

Talk to your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

Some drugs may interact with XIGDUO. Tell your doctor if you are taking:

  • Medicines for diabetes; low blood sugar (hypoglycemia) may occur if you already take another medication to treat diabetes.

  • Cationic drugs (e.g. amiloride, digoxin, morphine, procainamide, quinidine, quinine, ranitidine, triamterene, trimethoprim and vancomycin).
  • Certain “blood thinners” (phenprocoumon or other Vitamin K anticoagulants).
  • Diuretics (water pills), especially loop diuretics, that may increase the risk of lactic acidosis (e.g. furosemide).
  • Other drugs that tend to produce high blood sugar (hyperglycemia) and may lead to a loss of blood sugar control. Some example of drugs that can increase the blood sugar include:
    • Thiazide and other diuretics (water pills)
    • Corticosteroids (used to treat joint pain and swelling)
    • Phenothiazines (used to treat schizophrenia)
    • Thyroid products
