Metformin Hydrochloride

Metformin hydrochloride is a widely prescribed first-line medication for type 2 diabetes, acting as an antihyperglycemic agent to lower blood glucose levels without typically causing hypoglycemia. It improves insulin sensitivity, decreases hepatic glucose production, and is used for managing PCOS. Common side effects include diarrhea, nausea, and abdominal discomfort.
