The U.S. Food and Drug Administration, or FDA, is concerned about Z-Pak antibiotics, also known as Zithromax or azithromycin. These FDA concerns involve such potential Z-Pak side effects injuries as heart failure and liver failure.
In May of 2012, the FDA indicated its awareness of a study featured in the New England Journal of Medicine dated May 17, 2012 concerning heart failure or cardiovascular death dangers for persons taking the Zithromax or azithromycin antiobiotic drugs featured in a Z-Pak.
The FDA concludes that persons using azithromycin shouldn’t discontinue taking the antibiotic without consulting their healthcare professional. The FDA also wanted to ensure such healthcare professionals are aware of the chance of “QT interval prolongation” and heart arrhythmias when considering writing a prescription for, or administering, such antibacterial drugs (antibiotics).
The FDA also has noted that azithromycin, the active ingredient in the Zithromax tablets in a six-tablet Z-Pak, is in an antibacterial class known as macrolides. The FDA has noted that these have been “associated with cardiovascular effects,” including the prolongation of the QT interval, which in turn can lead to a fatally abnormal heart rhythm.
The QT interval concerns the heart’s electrical cycle. A prolonged QT interval can cause abrupt death. The heart’s QT interval is a measure of its electrical cycle comparing the time between the start of the heart’s Q wave and the finish of the heart’s T wave. A life-threatening risk arises when a QT interval is prolonged, meaning the heart beat is slower — perhaps too slow.
The FDA also has been evaluating the risk of liver failure caused by azithromycin, the drug in Zithromax tablets that are featured in a Z-Pak.
In February of 2011, the FDA ordered a change in the label, or package insert, for Zithromax products, which include Z-Paks. This label change added FDA warnings about liver failure and additional hepatic or liver side effects.
So far an FDA recall of Zithromax, Z-Pak products or azithromycin has not been issued. However, a Z-Pak recall or Zithromax recall eventually could come — and until then, it’s possible to launch a Z-Pak lawsuit or Zithromax lawsuit for heart failure or liver failure as a Z-Pak side effects injury or Zithromax side effects injury.
