|Thiazolidinediones: A Type 2 Diabetes Medication|
How do they work?
Thiazolidinediones work by reducing the insulin resistance in the body. As a result, the body is in a better position to respond to the insulin. This helps maintain normal blood sugar levels. However, they do not help the body to produce more insulin. Also, this medication does not work as a replacement for insulin. It just works as a substitute for a healthy diet that is ideally recommended for diabetics, by the doctors.
Thiazolidinediones are oral medications. They may be used alone or along with other diabetes medications. For increased effectiveness, it is important that the medicines be taken every day. Thiazolidinediones may take up to three months to show full effect. Also, do not stop using them unless asked to do so by your health care provider.
Time and again, there have been safety concerns with Thiazolidinediones. Thus, the medication must be taken under the vigilance of your health care provider.
