What is Xigduo XR?

Xigduo XR extended release tablets contain a combination of dapagliflozin and metformin. Dapagliflozin and metformin are oral diabetes medicines that help control blood sugar levels. Dapagliflozin works by helping the kidneys get rid of glucose from your bloodstream. Metformin lowers glucose production in the liver and also causes your intestines to absorb less glucose.

Xigduo XR is used together with diet and exercise to treat type 2 diabetes.

Xigduo XR is not for treating type 1 diabetes.

Important information

You should not use Xigduo XR if you have moderate to severe kidney disease, if you are on dialysis, or if you have metabolic acidosis. Xigduo XR is not for treating type 1 diabetes.

If you need to have any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking Xigduo XR.

Xigduo XR may cause a serious condition called lactic acidosis. Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, slow or uneven heart rate, dizziness, or feeling very weak or tired.

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.
