Metformin is a medication used to treat type 2 diabetes and gestational diabetes. It helps lower blood sugar levels by improving the way the body handles insulin. Additionally, it is sometimes used to manage symptoms of polycystic ovary syndrome (PCOS) by lowering insulin and blood sugar levels, which can improve ovulation and encourage regular periods, even in women without diabetes
. Metformin is not used to treat type 1 diabetes or patients who have insulin- dependent diabetes
. It may also have cardiovascular benefits and is used off-label to treat conditions such as prediabetes and gestational diabetes
