What is Actos?
Actos (pioglitazone) is an oral diabetes medicine that helps control blood sugar levels.
Actos is for people with type 2 diabetes.
Actos is not for treating type 1 diabetes.
You should not use Actos if you have severe or uncontrolled heart failure, active bladder cancer, or diabetic ketoacidosis (call your doctor for treatment with insulin). This medicine is not for treating type 1 diabetes.
Actos can cause or worsen congestive heart failure. Stop using this medicine and call your doctor at once if you have shortness of breath (even with mild exertion), swelling, or rapid weight gain.
Before taking this medicine
You should not use Actos if you are allergic to pioglitazone, or if you have severe or uncontrolled heart failure, active bladder cancer, or diabetic ketoacidosis (call your doctor for treatment with insulin).
To make sure Actos is safe for you, tell your doctor if you have:
congestive heart failure or heart disease;
a history of bladder cancer;
a history of heart attack or stroke; or
This medication may increase your risk of developing bladder cancer. Talk with your doctor about your specific risk.
Taking Actos 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.
Follow your doctor's instructions about using Actos if you are pregnant. Blood sugar control is very important during pregnancy, and your dose needs may be different during each trimester of pregnancy.
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 be more likely than men to have bone fractures in the upper arm, hand, or foot while taking this medicine. Talk with your doctor if you are concerned about this possibility.
It is not known whether pioglitazone passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
Actos is not approved for use by anyone younger than 18 years old.
How should I take Actos?
Take Actos exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Actos is usually taken once daily. You may take the medicine with or without food.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, pale skin, irritability, dizziness, feeling shaky, or trouble concentrating.
Keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency. If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.
Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your medication dose or schedule without your doctor's advice.
Use Actos regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Actos is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.
