The FDA is warning the public about Zithromax, one of the most commonly-prescribed antibiotics.
The FDA says azithromycin, which is often referred to as z-pack, has been linked to a potentially fatal irregular heartbeat.
The drug can change the heart's electrical activity and lead to a condition called a "prolonged QT interval," which means the heart's timing gets thrown off.
The FDA says doctors should be careful prescribing azithromycin for patients who are at risk for heart problems.
