Diabetes Home > Micronase

Micronase is used to lower blood sugar levels in people with type 2 diabetes. The medication works by increasing insulin production in the pancreas and helping the body respond better to insulin. Micronase comes in tablet form, and is typically taken once or twice a day. Possible symptoms of an overdose can include shakiness, a fast heartbeat, and confusion.

How Does Micronase Work?

Micronase is part of a class of diabetes medications known as sulfonylureas. A sulfonylurea such as Micronase helps the pancreas to produce more insulin. They may also help the cells of the body respond better to insulin. This helps to lower blood sugar and keep it under better control.

When and How to Take Micronase

General considerations for when and how to take Micronase include the following:
  • Micronase comes in tablet form. It should be taken by mouth, usually once or twice a day.
  • When taking the drug once daily, it should be taken with breakfast (or the first main meal).
  • When taking Micronase twice daily, the first dose should be taken with breakfast (or the first main meal).
  • Micronase should be taken at the same time(s) each day to maintain an even level of the drug in your blood.
  • For the drug to work properly, it must be taken as prescribed. Micronase will not work if you stop taking it.
