Actos is an oral diabetes medicine that helps control blood sugar levels.
Actos is for people with type 2 (non-insulin-dependent) diabetes. It is sometimes used in combination with insulin or other medications, but it is not for treating type 1 diabetes.
Actos may also be used for purposes other than those listed in this medication guide.
Most important: Do not use Actos if you have type 1 diabetes, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).
Before taking Actos, tell your doctor if you have congestive heart failure or heart disease, a history of heart attack or stroke, or liver disease.
Know the signs of low blood sugar (hypoglycemia) and how to recognize them, including hunger, headache, confusion, irritability, drowsiness, weakness, dizziness, tremors, sweating, fast heartbeat, seizure (convulsions), fainting, or coma (severe hypoglycemia can be fatal). Always keep a source of sugar available in case you have symptoms of low blood sugar.
Some women using Actos have started having menstrual periods, even after not having a period for a long time due to a medical condition. You may be able to get pregnant if your periods restart. Talk with your doctor about the need for birth control.
Women may also be more likely than men to have bone fractures in the upper arm, hand, or foot while taking Actos. Talk with your doctor if you are concerned about this possibility.
Certain oral diabetes medications may increase your risk of serious heart problems. However, not treating your diabetes can damage your heart and other organs. Talk to your doctor about the risks and benefits of treating your diabetes with Actos.
