What is Actoplus Met?
Actoplus Met contains a combination of metformin and pioglitazone, two oral diabetes medicines that help control blood sugar levels.
Actoplus Met is for people with type 2 diabetes who do not use daily insulin injections.
Actoplus Met is not for treating type 1 diabetes.
You should not use Actoplus Met if you have severe or uncontrolled heart failure, kidney problems, active bladder cancer, metabolic acidosis, or diabetic ketoacidosis (call your doctor for treatment with insulin). Actoplus Met is not for treating type 1 diabetes.
Actoplus Met can cause or worsen congestive heart failure. Call your doctor at once if you have shortness of breath (even with mild exertion), swelling, or rapid weight gain.
If you need to have any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking Actoplus Met.
Some people develop lactic acidosis while taking metformin. Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, slow or uneven heart rate, dizziness, or feeling very weak or tired.
Before taking this medicine
You should not use Actoplus Met if you are allergic to metformin or pioglitazone, or if you have:
severe or uncontrolled heart failure;
active bladder cancer;
metabolic acidosis; or
diabetic ketoacidosis (call your doctor for treatment with insulin).
If you need to have any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking Actoplus Met. Be sure your caregivers know ahead of time that you are using this medication.
Some people taking metformin develop a serious condition called lactic acidosis. This may be more likely if you have liver or kidney disease, congestive heart failure, a severe infection, if you are dehydrated, or if you drink large amounts of alcohol. Talk with your doctor about your risk.
To make sure Actoplus Met 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;
liver disease; or
if you are 80 years or older.
Actoplus Met may increase your risk of developing bladder cancer. Talk with your doctor about your specific risk.
Taking Actoplus Met 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 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 of pregnancy.
Some women using Actoplus Met 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 medicine that contains pioglitazone. Talk with your doctor if you are concerned about this possibility.
It is not known whether metformin and pioglitazone passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
Actoplus Met should not be given to a child.
How should I take Actoplus Met?
Take Actoplus Met exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Take Actoplus Met with meals. Take the extended-release (XR) tablet once daily with your evening meal.
Do not crush, chew, or break an extended-release tablet. Swallow it whole.
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. Always 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 Actoplus Met dosage or dosing schedule without your doctor's advice.
Use Actoplus Met regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
If you take extra vitamin B12 while you are taking Actoplus Met, take only the amount of vitamin B12 that your doctor has prescribed.
Actoplus Met 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.
