Metformin (Metformin hydrochloride) — Uses, Dosage, Side Effects & Safety

Drug class: Endocrine & Metabolic Disorders

Overview

Metformin is a prescription medication used to help control high blood sugar in people with type 2 diabetes. It is often the first medicine prescribed for diabetes management and may be used alone or with other diabetes medications. Metformin helps your body respond better to insulin and decreases the amount of sugar made by your liver. By lowering blood sugar, metformin helps reduce the risk of serious diabetes complications such as kidney damage, nerve problems, and blindness. It is not used to treat type 1 diabetes. Most people tolerate metformin well, but some may experience mild stomach upset, especially when starting treatment. Key points: Take metformin as directed, usually with food to reduce stomach upset. Regular monitoring of blood sugar and kidney function is important. Always inform your healthcare provider about all medicines and supplements you are taking.
