Linagliptin is a medication used to manage type 2 diabetes. It belongs to a class of drugs called DPP-4 inhibitors, which help lower blood sugar levels by increasing insulin production and decreasing glucose production in the liver. Linagliptin is often prescribed alongside diet and exercise to improve glycemic control. This medication is taken orally, usually once a day, and does not require dose adjustments for patients with kidney problems. Common side effects may include headaches and gastrointestinal issues, but it is generally well-tolerated. Regular monitoring of blood sugar levels is essential while using linagliptin.
