Glipizide/metformin is a combination of two medications: glipizide, which helps your pancreas release insulin, and metformin, which lowers the amount of sugar your body makes and absorbs. It's best take it with meals to avoid low blood sugar. Saxagliptin helps insulin stay in your body longer by blocking a protein that breaks it down. You can take it once daily, with or without food.
