"Mutations in the TTN gene, which are commonly found in idiopathic dilated cardiomyopathy, also seem common in peripartum cardiomyopathyâ€”which may finally help explain why the latter condition occurs, new research suggests.
Amiodarone has the potential to cause serious side effects that limit its use to life-threatening and hemodynamically unstable cardiac arrhythmias. Advise female patients to discontinue nursing while being treated with amiodarone, as breast-feeding could expose the nursing infant to a significant dose of the drug. Recommend that patients avoid grapefruit juice, over-the-counter cough medicine (that commonly contain dextromethorphan), and St. John's Wort. Inform patients that most manufacturers of corneal refractive laser surgery devices contraindicate corneal refractive laser surgery in patients taking amiodarone. Discuss the symptoms of hypo-and hyper-thyroidism, particularly if patients will be transitioned to oral amiodarone.
