What is this medication and its most common uses?Glipizide/metformin is a medicine used along with diet and exercise to help control high blood sugar in adults with type 2 diabetes. Glipizide/metformin is a combination medicine that works in two different ways to lower your blood sugar levels.
What should I know when beginning and continuing on this medication?How does this medication work?
Glipizide helps your body release more insulin. Metformin helps your body respond better to the insulin it makes naturally, decreasing the amount of sugar your liver makes, and decreasing the amount of sugar your intestines absorb. Together, they help to control your blood sugar.
What are the beneficial effects of this medication and when should I begin to have results?
What: Lowering your blood sugar to a normal level may prevent or delay potential complications associated with diabetes, such as blindness, kidney failure, or heart problems. Also, the combination of medicines in glipizide/metformin provides better control of blood sugar compared to either glipizide or metformin alone.
When: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. It is important that you take glipizide/metformin exactly as your healthcare provider has prescribed.
How do I know it is working?
