Pioglitazone does not usually cause low blood sugar (hypoglycemia). Low blood sugar may occur if this drug is prescribed with other anti-diabetic medications (such as insulin or a sulfonylurea). Low blood sugar is more likely if you drink large amounts of alcohol, do unusually heavy exercise, or do not consume enough calories from food.

Tell your doctor right away about the reaction and the use of this product.
