Cordarone

Generic Name: Amiodarone (A-mi-OH-da-rone)Brand Name: Examples include Cordarone and Pacerone

Cordarone should only be used in patients with life-threatening irregular heartbeat. Worsening of irregular heartbeat, life-threatening lung disease, and serious liver problems may occur with use of Cordarone . Alternative medicines should be tried before Cordarone is used. Initial use of Cordarone requires close monitoring and dose selection may be difficult. It is very common to require a dosage decrease or discontinuation of treatment. The recurrence of the irregular heartbeat after discontinuation or dosage adjustment is unpredictable and hospitalization may be required.

Cordarone is used for:

Treating life-threatening recurrent heart rhythm disturbances in patients who cannot tolerate or do not respond well to other medicines. It may also be used for other conditions as determined by your doctor.

Cordarone is an antiarrhythmic. It works by stabilizing the heart rhythm in conditions in which the heart is beating too fast or in an irregular rhythm. It is usually used in situations in which the abnormal heart rhythms, if not treated, could cause death.

Do NOT use Cordarone if:

  • you are allergic to any ingredient in Cordarone , including iodine
  • you have complete, second degree, third degree, or severe sinoatrial heart block; an abnormally slow heartbeat; or shock due to serious heart problems; or if you have had fainting due to slow heartbeat (except if you have a pacemaker)
  • you are taking cisapride, dofetilide, an H1 antagonist (eg, astemizole, loratadine, terfenadine), an HIV protease inhibitor (eg, ritonavir), a phosphodiesterase type 5 inhibitor (eg, vardenafil), or a streptogramin (eg, dalfopristin, quinupristin)

Contact your doctor or health care provider right away if any of these apply to you.
