Tolbutamide — Uses, Dosage, Side Effects & Safety

Drug class: Sulfonylurea antidiabetic agent

Overview

Tolbutamide is an oral medication used to help control blood sugar levels in people with type 2 diabetes mellitus. It belongs to the sulfonylurea class of drugs, which work by stimulating the pancreas to release more insulin. This medication is typically used when diet and exercise alone are not enough to manage blood sugar. Tolbutamide helps lower blood glucose, reducing the risk of complications such as kidney damage, nerve problems, and vision issues. It is not used for type 1 diabetes or diabetic ketoacidosis. Patients should know that tolbutamide is most effective when combined with a healthy lifestyle. Regular monitoring of blood sugar is important, and the medication should be taken exactly as prescribed to avoid low blood sugar (hypoglycemia).
