Regular use, along with healthy eating and daily activity, helps keep blood sugar stable and lowers the risk of long-term complications.
Brand Name Options
Gliclazide is sold under many brand names in different countries. The most common ones are Diamicron and Diamicron MR, which is the slow-release version.
Since gliclazide is a generic drug, many companies make it and offer it under their own names.
People may see brands like Zicron, Laaglyda MR, or other local versions depending on where they live.
It is not available in the United States, but it can be found in many other regions and is often used as a trusted option for type 2 diabetes.
