Summary
Tolbutamide is used to treat type 2 diabetes, which is a condition where the body doesn't use insulin properly, leading to high blood sugar levels. It is not used for type 1 diabetes or diabetic ketoacidosis, which is a dangerous buildup of acid in the blood.
Tolbutamide works by stimulating the pancreas to release more insulin, which is a hormone that helps lower blood sugar levels. This process helps the body use sugar more effectively, improving blood sugar control in people with type 2 diabetes.
The usual starting dose of Tolbutamide for adults is 500 mg to 1000 mg daily, taken in divided doses before meals. The maximum recommended dose is 3000 mg per day. It should be taken with food to reduce stomach upset.
Common side effects of Tolbutamide include low blood sugar, which is called hypoglycemia, and gastrointestinal issues like nausea or upset stomach. These effects vary from person to person and are usually mild.
Tolbutamide can cause low blood sugar, especially if meals are skipped or exercise is increased. It should not be used by people with type 1 diabetes or diabetic ketoacidosis. Regular liver function tests are recommended due to potential liver problems.
