Details with Side Effects
Read this Medication Guide before you start taking MULTAQ and each time you get a refill. There may be new information. This information does not take the place of talking with your doctor about your medical condition or your treatment.
What is the most important information I should know about MULTAQ?
MULTAQ can cause serious side effects.
Do not take MULTAQ if you:
1. have symptoms of heart failure that recently worsened and you were hospitalized, or if you have severe heart failure.
MULTAQ doubles your risk of dying if you have these conditions. Heart failure means your heart does not pump blood through your body as well as it should.
Call your doctor right away if you have any signs or symptoms of heart failure during treatment with MULTAQ:
- shortness of breath or wheezing at rest
- wheezing, chest tightness or coughing up frothy sputum at rest, nighttime or after minor exercise
- trouble sleeping or waking up at night because of breathing problems
- using more pillows to prop yourself up at night so you can breathe more easily
- gaining more than 5 pounds quickly
- increasing swelling of feet or legs
2. have a type of atrial fibrillation (irregular heart rhythm) called permanent atrial fibrillation (AF).
You and your doctor may decide not to try to change your heart rhythm back to a normal heart rhythm or your heart rhythm cannot be changed back to a normal rhythm. If you have permanent AF and take MULTAQ, you have a higher risk of death, stroke, and needing to be treated in a hospital for your heart failure.
Your doctor will monitor your heart rhythm regularly to make sure your heartbeat keeps a normal rhythm.
Call your doctor right away if you notice that your pulse is irregular during treatment with MULTAQ. This is a sign that you are in atrial fibrillation.
MULTAQ may cause liver problems, including life-threatening liver failure.
Your doctor may order blood tests to check your liver before you start taking MULTAQ and during treatment. In some cases MULTAQ treatment may need to be stopped.
Call your doctor right away if you develop any of these signs and symptoms of liver problems during treatment with MULTAQ:
- loss of appetite, nausea, vomiting
- fever, feeling unwell, unusual tiredness
- yellowing of the skin or the whites of the eyes (jaundice)
- unusual darkening of the urine
- right upper stomach area pain or discomfort
What is MULTAQ?
MULTAQ is a prescription medicine used to lower the chance that you will need to go into the hospital for atrial fibrillation. It is meant for people who have had certain types of atrial fibrillation (paroxysmal or persistent AF) in the past, but are now in normal rhythm.
It is not known if MULTAQ is safe and effective in children younger than age 18 years old.
