Pioglitazone is a medication primarily used to treat type 2 diabetes. It belongs to a class of drugs known as thiazolidinediones, which help improve insulin sensitivity in the body. By enhancing the way cells respond to insulin, pioglitazone helps lower blood sugar levels and can contribute to better overall glucose control. This medication is usually prescribed alongside diet and exercise changes. While it can be effective, pioglitazone may have side effects, including weight gain and an increased risk of heart failure. Patients should discuss potential risks and benefits with their healthcare provider before starting treatment.
