Azithromycin (Zithromax®) Cardiac Dangers*

We are no longer accepting Zithromax cases

Azithromycin (also known as Zithromax®, Z-Pak®, and ZMax) is a common antibiotic prescribed to fight bacterial infections. It’s also one of the most popular prescription medications on the market. Because the drug has a short and easy dosage regimen, patients can quickly finish their course of treatment, which can help reduce the risk of developing drug-resistant illnesses.

Recently, azithromycin has been linked to increased risk of abnormal changes in the electrical activity of the heart, which could result in fatal irregular heart rhythms.

Study Links Zithromax® to Cardiovascular Side Effects

A Vanderbilt University study which analyzed millions of prescriptions found that patients taking azithromycin had two and one half times the odds of dying due to cardiovascular issues than patients taking amoxicillin (another common antibiotic prescribed for similar medical conditions).

In March 2013, the U.S. Food and Drug Administration (FDA) issued a safety alert citing a link between azithromycin and potentially fatal abnormal heart rhythms. The drug can prolong a patient’s QT interval, which is a measure of the heart’s electrical health. A prolonged QT level can put patients at risk for sudden death.

The FDA has warned health care professionals to consider the risks of azithromycin when choosing treatment options for patients at risk for cardiovascular issues.

Patients at Risk for Z-Pak® Heart Problems

The FDA states that patients at the highest risk for heart problems after taking azithromycin include those who:

  • Already suffer from QT interval prolongation.
  • Have low blood levels of potassium or magnesium.
  • Have a slow heart rate.
  • Are using certain drugs to treat abnormal heart rhythms.

The personal injury lawyers at Cory Watson Attorneys settled their lawsuits and recovered compensation for their clients injured by the use of Azithromycin.
