STAY IN NORMAL RHYTHM

What is the most important information I should know about MULTAQ?

MULTAQ may cause serious side effects, including:

• Increased risk of death, stroke, and heart failure in people with:

  • A certain type of heart failure called decompensated heart failure. Heart failure is when your heart does not pump blood through your body as well as it should. MULTAQ can cause new or worsening heart failure.
    Do not take MULTAQ if you have symptoms of heart failure that recently worsened and you were hospitalized, or if you have severe heart failure.
    Call your healthcare provider right away if you develop any of the following 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

  • A certain type of irregular heartbeat (rhythm) called permanent atrial fibrillation (AFib). Permanent AFib is when you and your healthcare provider 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.
  • Do not take MULTAQ if you have permanent AFib. Your healthcare provider should check your heart rhythm regularly to make sure your heart keeps a normal rhythm.
  • Call your healthcare provider right away if you develop any of the following signs or symptoms of AFib during treatment with MULTAQ such as: fast or irregular heartbeat or pulse; chest pain; dizziness or lightheadedness; tiredness or weakness; reduced ability to exercise; shortness of breath

MULTAQ doubles your risk of dying if you have these conditions. Your healthcare provider may give you a medicine to help prevent blood clots and decrease your risk of stroke during treatment with MULTAQ. Tell your healthcare provider right away if you develop any of the following signs or symptoms of stroke during treatment with MULTAQ such as: numbness or weakness in the face, arms, or legs, especially on 1 side of the body; confusion, trouble speaking, or difficulty understanding things; trouble seeing in 1 or both eyes; trouble walking, dizziness, loss of balance, or lack of coordination.

• Liver problems. MULTAQ may cause severe liver problems, including life-threatening liver failure. Do not take MULTAQ if you have severe liver problems. Your healthcare provider may order blood tests to check your liver before you start taking MULTAQ and during treatment.
  Call your healthcare provider right away if you develop any of the following signs and symptoms of liver problems during treatment with MULTAQ: 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; right upper stomach area pain or discomfort

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking MULTAQ with certain other medicines may affect the amount of MULTAQ or other medicines in your blood and may increase your risk of side effects or affect how well MULTAQ or the other medicines work.
