This prescription medication is used to treat type 2 diabetes mellitus by helping control blood sugar levels. Each pack contains 30 extended-release tablets. The XR (extended-release) formulation allows for once-daily dosing, which may help improve medication adherence compared to immediate-release versions. The tablets should be taken with meals to reduce gastrointestinal side effects. This medication works by decreasing glucose production in the liver, reducing glucose absorption from the intestines, and improving insulin sensitivity.
