Many people in the San Antonio area take Amiodarone to prevent irregular heart activity, such as arrhythmias. Arrhythmias prevent proper blood flow to the heart and can lead to cardiac arrest. At-risk patients also receive the medication before surgeries to minimize the risk of complications. The Food and Drug Administration approved Amiodarone in 1985 as a treatment for serious arrhythmias. Since its approval, there have been links to the medication to many complaints of life-threatening symptoms and death.
