Read the Medication Guide that comes with Cordarone Tablets before you start taking them and each time you get a refill. There may be new information. This Medication Guide 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 Cordarone Tablets? Cordarone Tablets can cause serious side effects that can lead to death including:

  • lung damage
  • liver damage
  • worse heartbeat problems

Call your doctor or get medical help right away if you have any symptoms such as the following:

  • shortness of breath, wheezing, or any other trouble breathing; coughing, chest pain, or spitting up of blood
  • nausea or vomiting; passing brown or dark-colored urine; feel more tired than usual; your skin and whites of your eyes get yellow; or have stomach pain

  • weakness, weight loss or weight gain, heat or cold intolerance, hair thinning, sweating, changes in your menses, swelling of your neck (goiter), nervousness, irritability, restlessness, decreased concentration, depression in the elderly, or tremor.

Because of these possible side effects, Cordarone Tablets should only be used in adults with life-threatening heartbeat problems called ventricular arrhythmias, for which other treatments did not work or were not tolerated.

Cordarone Tablets can cause other serious side effects. See “What are the possible or reasonably likely side effects of Cordarone Tablets?” for more information.
