What is XIGDUO used for?
XIGDUO (Dapagliflozin and Metformin) 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 a sulfonylurea as separate tablets, or
- in patients taking dapagliflozin (FORXIGA), metformin and sitagliptin as separate tablets, or
- in patients taking dapagliflozin (FORXIGA), metformin and insulin.
How does XIGDUO work?
XIGDUO contains dapagliflozin and metformin hydrochloride. Dapagliflozin removes excess sugar 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.
Who should not take XIGDUO?
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 have had ketoacidosis with or without coma.
- have diabetic ketoacidosis (DKA, a complication of diabetes) or a history of DKA.
- 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 short-term ‘binge’.

Warnings and Precautions for XIGDUO:
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:).
- Diabetic ketoacidosis (DKA) is a serious and life-threatening condition that requires urgent hospitalization. DKA has been reported in patients with type 2 diabetes mellitus (T2DM) with normal or high blood sugar levels, who are treated with dapagliflozin and other sodium-glucose co-transporter 2 (SGLT2) inhibitors. Some cases of DKA have led to death.
- Seek medical attention right away and stop taking XIGDUO immediately if you have any of the following symptoms (even if your blood sugar levels are normal): difficulty breathing, nausea, vomiting, stomach pain, loss of appetite, confusion, feeling very thirsty, feeling unusually tired, a sweet smell to the breath, a sweet or metallic taste in the mouth, or a different odour to urine or sweat.
- Do not use XIGDUO if you have:
- DKA or a history of DKA
- type 1 diabetes
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:
- have type 1 diabetes (your body does not produce any insulin). XIGDUO should not be used in patients with Type 1 diabetes.
- have an increased chance of developing DKA, including if you:
- are dehydrated or suffer from excessive vomiting, diarrhea, or sweating;
- are on a very low carbohydrate diet;
- drink a lot of alcohol;
- have/have had problems with your pancreas, including pancreatitis or surgery on your pancreas;
- are hospitalized for major surgery, serious infection or serious medical illnesses;
- have a history of diabetic ketoacidosis (DKA).
- are older than 65 years of age.
- 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).
- 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).
- often get urinary tract infections.
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.
XIGDUO may cause abnormal kidney function. Your doctor will do blood tests to monitor how well your kidneys are working while you are taking XIGDUO.
XIGDUO may cause necrotizing fasciitis of the perineum (area between and around the anus and genitals). This is a rare but serious and potentially life-threatening infection that can affect both men and women. It is also known as Fournier’s gangrene and requires urgent treatment. If you experience tenderness, redness or swelling of the genitals or the area from the genitals to the rectum, especially if you also have a fever or are feeling very weak, tired, or uncomfortable, seek medical attention immediately. These may be signs of Fournier’s gangrene.
XIGDUO may cause dizziness or lightheadedness. Do not drive or use machines until you know how the medicine affects you.
What are some interactions with XIGDUO?
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.
- Nifedipine (used to treat high blood pressure and chest pain).
- 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 examples 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
- Estrogens or estrogens plus progestogen
- Oral contraceptives (birth control pills)
- Phenytoin (used to treat epilepsy)
- Nicotinic Acid
- Sympathomimetics (used for heart problems)
- Calcium channel blocking drugs (used for high blood pressure)
- Isoniazid (used to treat tuberculosis)
- Beta-2-agonists (used to treat breathing problems)
- ACE inhibitor drugs (may lower blood glucose).
