FDA Warns That Zithromax Can Cause Fatal Irregular Heart Rhythm

March 14, 2013, by Price Benowitz LLP

The US Food and Drug Administration warned on Tuesday that the popular antibiotic azithromycin, sold as Zithromax, can cause a potentially fatal irregular heart rhythm in some patients. Generic versions of Zithromax are also available.

The Agency said the move follows its review of a study published in The New England Journal of Medicine. The study compared the risk of cadiovascular death in patients who took Zithromax with those who took several other antibiotics, including amoxicillin. It found that patients who took Zithromax made by Pfizer Inc, had higher rates of fatal heart rhythms.

The group most at risk includes people with low levels of potassium or magnesium, a slower than normal heart rate, or people who take certain drugs used to treat abnormal heart rhythms, or arrhythmias
