What is Actos?
Actos is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus.
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).
This medication may increase your risk of developing bladder cancer. Talk with your doctor about your specific risk.
To make sure Actos is safe for you, tell your doctor if you have ever had:
congestive heart failure or heart disease;
a heart attack or stroke;
eye problems caused by diabetes;
bladder cancer; or
Actos may increase your risk of serious heart problems, but not treating your diabetes can also damage your heart and other organs. Talk to your doctor about the risks and benefits of this medicine.
Follow your doctor's instructions about using this medicine if you are pregnant. Blood sugar control is very important during pregnancy, and your dose needs may be different during each trimester.
Pioglitazone may stimulate ovulation in a premenopausal woman and may increase the risk of unintended pregnancy. Talk to your doctor about your risk.
Women may be more likely to have a broken bone while using Actos. Talk with your doctor about ways to keep your bones healthy.
It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.
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 and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
Actos is usually taken once daily, with or without food.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, and feeling shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.
Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.
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.
Actos dosing information
Usual Adult Dose for Diabetes Type 2:
-Patients without congestive heart failure:
Initial dose: 15 mg or 30 mg orally once a day
-Patients with congestive heart failure (New York Heart Association [NYHA] Class I or II):
Initial dose: 15 mg orally once a day
Maintenance dose: 15 mg to 45 mg orally once a day based on glycemic response as determined by HbA1c
