What is Glyset?

Return to top

Glyset is used as an add-on treatment to diet to improve high blood sugar levels caused by type 2 diabetes mellitus. Glyset may also be used in combination with a sulfonylurea (such as Glipizide, Glimepiride, or Glyburide) when diet plus either Glyset or a sulfonylurea alone do not result in adequate blood sugar control.


What is the most important information I should know about Glyset?

Return to top

Glyset itself does not cause low blood sugar even when administered to patients in the fasted state. However, when Glyset is given in combination with a sulfonylurea or insulin, it will cause a further lowering of blood sugar.

It is important to continue to adhere to dietary instructions, a regular exercise program, and regular testing of urine or blood glucose.

Glyset when administered alone should not cause hypoglycemia (very low levels of blood sugar that could be life-threatening). However, sulfonylureas and insulin may cause hypoglycemia. When Glyset is administered with a sulfonylurea drug or insulin, the combination will further lower your blood glucose and has the potential of causing hypoglycemia.

When diabetic patients are exposed to stress such as fever, infection, trauma, or surgery, a temporary loss of blood glucose may occur. When this happens, temporary insulin therapy may be necessary.


Who should not take Glyset?
