Diamicron is an oral tablet made up of an oral hypoglycemic drug called gliclazide. This medication is available as a generic alternative in 80mg!

Diamicron is a diabetes type 2 medication used to control blood sugar when diet, exercise and weight reduction have not be successful alone without medications.
