Avandamet

Generic name: Metformin And Rosiglitazone
Drug class: Antidiabetic combinations

Usage of Avandamet

Avandamet contains a combination of metformin and rosiglitazone, two oral diabetes medicines that help control blood sugar levels.

Avandamet is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus. This medicine is not for treating type 1 diabetes.

Avandamet is not recommended for use with insulin. Taking this medicine while you are using insulin may increase your risk of serious heart problems.

Avandamet side effects

Get emergency medical help if you have signs of an allergic reaction to Avandamet: hives, itching; difficult breathing; trouble swallowing; swelling of your face, lips, tongue, or throat.

Early symptoms of lactic acidosis may get worse over time and this condition can be fatal. Get emergency medical help if you have even mild symptoms: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, fast or uneven heart rate, dizziness, or feeling very weak or tired.

Call your doctor at once if you have:

changes in your vision;

a light-headed feeling, like you might pass out;

low red blood cells (anemia) - pale skin, feeling light-headed or short of breath, rapid heart rate, trouble concentrating;

heart attack symptoms - chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating;

signs of heart failure - shortness of breath (even while lying down), swelling in your feet or ankles, rapid weight gain;

liver problems - nausea, vomiting, loss of appetite, upper stomach pain, tiredness, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes); or

severe skin reaction - fever, sore throat, swelling in your face or tongue, burning in your eyes, skin pain followed by a red or purple skin rash that spreads (especially in the face or upper body) and causes blistering and peeling.

Common Avandamet side effects may include:

nausea, vomiting, upset stomach, diarrhea;

headache, dizziness; or

joint pain.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Before taking Avandamet

You should not use Avandamet if you are allergic to metformin or rosiglitazone, or if you have:

severe or uncontrolled heart failure;

severe kidney problems; or

diabetic ketoacidosis (call your doctor for treatment).

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 Avandamet.

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 heart attack or stroke, a severe infection, if you are 65 or older, if you are dehydrated, or if you drink a lot of alcohol. Talk with your doctor about your risk.

To make sure Avandamet is safe for you, tell your doctor if you have ever had:

heart disease, congestive heart failure;

fluid retention;

kidney disease;

a problem with your adrenal or pituitary glands;

liver disease; or

eye problems caused by diabetes.

Women may be more likely than men to have bone fractures in the upper arm, hand, or foot while taking medicine that contains rosiglitazone. Talk with your doctor if you are concerned about this possibility.

Follow your doctor's instructions about using Avandamet 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 Avandamet 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.

It is not known whether metformin and rosiglitazone passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using Avandamet.

Avandamet is not approved for use by anyone younger than 18 years old.
