Uses For Qtern

Saxagliptin and dapagliflozin combination is used with diet and exercise to treat high blood sugar (glucose) levels in patients with type 2 diabetes. Saxagliptin helps to control blood sugar levels by making the pancreas gland release more insulin. It also signals the liver to stop producing sugar when there is too much sugar in the blood. Dapagliflozin works in the kidneys to prevent absorption of glucose (blood sugar). This helps lower the blood sugar level. This medicine does not help patients who have insulin-dependent or type 1 diabetes.

This medicine is available only with your doctor's prescription.
