How Pioglitazone Works

Pioglitazone works by increasing the body’s sensitivity to insulin, allowing cells to use glucose more effectively.

It helps to:

• Lower blood sugar levels.
• Improve insulin sensitivity.
• Reduce glucose production by the liver.
• Improve long-term blood sugar control (HbA1c).

Unlike some diabetes medicines, pioglitazone does not usually cause hypoglycemia (low blood sugar) when taken on its own.
