• if your ECG (electrocardiogram) shows a heart problem called “prolonged QT corrected interval” (this interval is more than 500 milliseconds),
• if you have a type of atrial fibrillation called permanent atrial fibrillation (AF). In permanent AF, the AF has been present for a long time (at least during 6 months) and a decision has been made not to change back your heart rhythm to atrial normal rhythm with a treatment called cardioversion,
• if you have instability (drops) in your blood pressure which can lead to inadequate arterial blood flow to your organs,
• if you have or had a problem where your heart cannot pump the blood round your body as well as it should (condition called heart failure). You may have swollen feet or legs, trouble breathing when lying down or sleeping, or shortness of breath when moving around,
• if the percentage of blood leaving your heart each time it contracts is too low (condition called left ventricular dysfunction),
• if you took amiodarone (another antiarrhythmic medicine) previously and experienced lung or liver problems,

• you have swollen feet or legs, trouble breathing when lying down or sleeping, shortness of breath when moving around, or weight increase (which are signs and symptoms of heart failure),
• tell your doctor immediately if you develop any of these signs and symptoms of liver problems: stomach (abdominal) area pain or discomfort, loss of appetite, nausea, vomiting, yellowing of the skin or the whites of the eyes (jaundice), unusual darkening of the urine, fatigue (especially in association with other symptoms listed above), itching,

While you are taking MULTAQ, your doctor may perform tests to check your medical condition and how the medicine is working for you.

• Your doctor may look at your heart’s electrical activity using an ECG (electrocardiogram) machine.
• Your doctor will order blood tests to check your liver function before you start taking MULTAQ and during treatment.
• If you are taking some medicines against blood clot formation such as warfarin, your doctor will order a blood test called INR to check how well your medicine is working.
• Your doctor may also do other blood tests. The results of one of the blood tests to check kidney function (blood creatinine levels) may be changed by MULTAQ. Your doctor will take this into account when checking your blood levels and will use another reference of the “normal” value of blood creatinine.
