Management of Type 2 Diabetes Mellitus. It is used alongside diet and exercise to improve glycemic control in adults.

It works by protecting "Incretin" hormones in the body. These hormones tell the pancreas to release insulin when blood sugar is high and signal the liver to stop producing excess sugar. Normally, an enzyme called DPP-4 breaks down these hormones quickly; Linagliptin blocks (inhibits) that enzyme, allowing the hormones to stay active longer.

Common: Nasopharyngitis (cold-like symptoms), cough, or headache. Metabolic: Very low risk of hypoglycemia (low blood sugar) when used alone. Serious (Rare): Pancreatitis (severe abdominal pain), joint pain, or skin blisters (bullous pemphigoid).
