Before you start to take pioglitazone, tell your doctor if you have or have ever had congestive heart failure, especially if your heart failure is so severe that you must limit your activity and are only comfortable when you are at rest or you must remain in a chair or bed. Also tell your doctor if you were born with a heart defect, and if you have or have ever had swelling of the arms, hands, feet, ankles, or lower legs; heart disease; high cholesterol or fats in the blood; high blood pressure; coronary artery disease (narrowing of the blood vessels that supply blood to the heart); a heart attack; an irregular heartbeat; or sleep apnea. Your doctor may tell you not to take pioglitazone or may monitor you carefully during your treatment.

Tell your doctor immediately if you have any of the following symptoms, especially when you first start taking pioglitazone or after your dose is increased: large weight gain in a short period of time; shortness of breath; swelling of the arms, hands, feet, ankles, or lower legs; swelling or pain in the stomach; waking up short of breath during the night; needing to sleep with extra pillows under your head in order to breathe easier while lying down; frequent dry cough or wheezing; difficulty thinking clearly or confusion; fast or racing heart beat; not able to walk or exercise as well; or increased tiredness.

WHY is this medicine prescribed?
Pioglitazone is used with a diet and exercise program and sometimes with other medications, to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). Pioglitazone is in a class of medications called thiazolidinediones. It works by increasing the body's sensitivity to insulin, a natural substance that helps control blood sugar levels. Pioglitazone is not used to treat type 1 diabetes (condition in which the body does not produce insulin and, therefore, cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may develop if high blood sugar is not treated).
HOW should this medicine be used?
Pioglitazone comes as a tablet to take by mouth. It is usually taken once daily with or without meals. Take pioglitazone at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take pioglitazone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of pioglitazone and gradually increase your dose.
Pioglitazone controls type 2 diabetes but does not cure it. It may take 2 weeks for your blood sugar to decrease and 2 to 3 months for you to feel the full effect of pioglitazone. Continue to take pioglitazone even if you feel well. Do not stop taking pioglitazone without talking to your doctor.
