Multaq Precautions
1. Multaq is not for people with heart failure with symptoms which recently worsened or for people with severe heart failure. People with these conditions who take Multaq have an increased chance of dying. Heart failure means your heart does not pump blood through your body as well as it should.
Do not take Multaq if you have symptoms of heart failure which recently worsened or if you have severe heart failure.
Call your doctor right away if you have any signs and symptoms of heart failure:
- 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. Multaq is not for people with a type of atrial fibrillation (irregular heart rhythm) called permanent atrial fibrillation (AF). In permanent AF, your heartbeat stays in atrial fibrillation and will not or cannot be changed back to a normal rhythm. Your doctor will monitor your heart rhythm regularly to make sure your heartbeat keeps a normal rhythm.
Do not take Multaq if you have permanent AF.
Call your doctor right away if you notice that your pulse is irregular. This is a sign that you are in atrial fibrillation.
- 3. 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. Tell your doctor right away if you develop any of these signs and symptoms of liver problems:
- loss of appetite, nausea, vomiting
- fever, feeling unwell, unusual tiredness
- itching
- yellowing of the skin or the whites of the eyes (jaundice)
- unusual darkening of the urine

Do not take Multaq if:
- You are in atrial fibrillation and your doctor is not planning to change you back into normal rhythm
- You have symptoms of heart failure which recently worsened or you have severe heart failure
- You have severe liver problems or had liver problems after using amiodarone (a medicine for abnormal heart rhythm)
- You take certain medicines that can change the amount of Multaq that gets into your body. See "Drug Interactions".
