Gliclazide
Summary
Gliclazide is used to manage type 2 diabetes, which is a condition where the body doesn't use insulin properly, leading to high blood sugar levels. It helps lower blood sugar levels and is often used alongside a healthy diet and exercise plan. It is not suitable for type 1 diabetes or diabetic ketoacidosis, which is a dangerous buildup of acid in the blood.
Gliclazide works by stimulating the pancreas to release more insulin, which is a hormone that helps lower blood sugar levels. Think of it like turning up the volume on a radio; Gliclazide increases the "volume" of insulin production, helping to manage blood sugar levels in people with type 2 diabetes.
Gliclazide is usually taken orally, which means by mouth, once or twice daily with food to reduce the risk of low blood sugar. The starting dose is typically 40 to 80 mg, and the maximum recommended dose is 320 mg per day. Always follow your doctor's specific dosing instructions for your personal health needs.
Common side effects of Gliclazide include low blood sugar, which is called hypoglycemia, and gastrointestinal issues like nausea or upset stomach. Hypoglycemia can cause dizziness, sweating, and confusion. If you notice new symptoms after starting Gliclazide, they might be temporary or unrelated to the medication. Talk with your doctor before stopping any medication.
