What is this medication for?
Rosiglitazone belongs to the class of medications called thiazolidinediones. It is used, along with diet and exercise, to treat adults with type 2 diabetes mellitus.
Rosiglitazone works by reducing levels of blood glucose (sugar in the blood) by helping insulin work more effectively, making it easier for glucose to enter into the tissues of the body.
Antidiabetes medications such as rosiglitazone are used when diet, exercise, and weight reduction have not been found to lower blood glucose well enough on their own. The full effects of this medication are usually seen within 8 to 12 weeks.
This medication is used along with diet and exercise to lower blood glucose. Lowering and controlling blood glucose levels may help reduce the risk of complications of diabetes (e.g., kidney disease, eye problems, nerve problems).

How should I use this medication?
The usual recommended starting dose of rosiglitazone is 4 mg once daily or 2 mg taken twice daily. The dose may be increased or decreased until blood glucose is controlled. The maximum daily dose is 8 mg once a day or 4 mg twice a day.
Rosiglitazone may be taken with or without food. It should be taken at the same time each day for optimal control of blood sugar levels.
Rosiglitazone can be used either alone or together with other antidiabetes medications (e.g., glyburide, metformin, insulin).
It is very important to monitor blood glucose levels on a regular basis as directed by your doctor or diabetes specialist.
