When you're prescribed amiodarone, a potent antiarrhythmic drug used to treat serious heart rhythm problems. Also known as Cordarone, it's one of the few medications that can save lives in cases of ventricular tachycardia or fibrillation—but it comes with a long list of hidden risks. Unlike most drugs that clear from your system in days, amiodarone sticks around for months, even after you stop taking it. That’s why amiodarone toxicity doesn’t always show up right away.
