The following information is a summary about Avandia. It is not intended to replace a doctor's instructions.
Why is this Avandia medication prescribed?
Avandia/Rosiglitazone is used, alone or in combination with other medications, to treat type 2 (noninsulin-dependent) diabetes (formerly 'adult-onset') in people whose diabetes cannot be controlled by diet and exercise alone. Avandia/Rosiglitazone is in a class of drugs called thiazolidinediones. These drugs (Avandia) work by increasing your body's sensitivity to insulin, a substance your body produces to help control blood sugar levels. Rosiglitazone is not used to treat type 1 (insulin-dependent) diabetes (formerly 'juvenile-onset').
This Avandia medication is sometimes prescribed for other uses; ask your doctor or Avandia pharmacist for more Avandia information.
How should this Avandia medicine be used?
Avandia/Rosiglitazone comes as a tablet to take by mouth. Avandia is usually taken once or twice daily with or without meals. Follow the Avandia directions on your Avandia prescription label carefully, and ask your doctor or Avandia pharmacist to explain any part you do not understand. Take Avandia/rosiglitazone exactly as directed. Do not take more or less of Avandia or take Avandia more often than prescribed by your doctor.
Avandia/Rosiglitazone controls type 2 diabetes but does not cure it. Continue to take Avandia/rosiglitazone even if you feel well. Do not stop taking Avandia/rosiglitazone without talking to your doctor.
