Amaryl 4 mg is an oral medication used to manage type 2 diabetes mellitus. It contains the active ingredient glimepiride, which belongs to the sulfonylurea class of drugs. Amaryl 4 mg works by stimulating the pancreas to produce more insulin and helps the body use insulin more efficiently. This lowers blood sugar levels and helps prevent complications associated with long-term uncontrolled diabetes, such as kidney damage, nerve problems, and heart disease. The Amaryl 4 mg medication is usually prescribed once daily, typically with breakfast or the first main meal of the day.
