We are investigating a claim where a man had heart issues that resulted in severe heart damage and resultant disability. As part of that investigation is was learned that a prescription antibiotic drug that he had taken, azithromycin, is now the subject of a federal Food and Drug Admininstration (FDA) alert that the drug can can cause abnormal changes in the electrical activity of the heart that may lead to a potentially fatal irregular heart rhythm.
Azithromycin, sold under the names Zithromax or Zmax, is one of the world’s best selling antibiotics. It is used to treat a wide variety of infections. This drug was prescribed more than 40 million times in 2011.
The FDA’s Data Summary provides information about a recent study of the drug and its impact on the cardiovascular system.
