Zithromax (azithromycin), commonly known as Z-Pak, is one of the world’s best-selling antibiotics used to treat and prevent certain bacterial infections including bronchitis, ear infections, pneumonia, and strep throat. The World Intellectual Property Organization (WIPO) reported in June 2003 that following the Zithromax patenting in 1981, Pfizer Inc. entered into a licensing agreement to further commercialize the drug, which has since produced over $1 billion annually from sales in the United States (i).

A Vanderbilt University study published in the New England Journal of Medicine, on May 17, 2012, noted the small but significant risk of cardiovascular death in patients being treated with Zithromax, particularly those with preexisting cardiovascular risk factors who were receiving antibacterial drug therapy (ii). The New York Times published another May 2012 article including commentary from doctors and professors at Vanderbilt University, Johns Hopkins University School of Medicine, and Columbia University Medical Center indicating that the most concerning Zithromax side effect is the risk of developing lethal arrhythmia (iii). The study determined that for every 1 million courses of Zithromax, there was an average of 85 deaths. In 2012, there were 21,417 adverse events reported including hospitalizations, life threatening conditions, deaths, and disability. Relying on the study published in the New England Journal of Medicine, the FDA issued a March 2013 safety communication about Zithromax and “the risk of potentially fatal heart rhythms” (iv).

Zithromax is primarily administered in tablet form to be taken orally. In light of this most common use, the Mayo Clinic updated its oral route Zithromax page in November 2012 to enumerate possible side effects of the antibiotic. Some common side effects of Zithromax use include swelling, abdominal pain, diarrhea, and nausea. Among the more serious Zithromax possible side effects are: liver damage and liver failure, arrhythmia, and sudden heart failure (v). In regards to cardiovascular-specific conditions, some symptoms may include: palpitations, fainting, ventricular fibrillation (the uncoordinated contraction of the cardiac muscle of the heart’s ventricles), cardiac arrest, and in some cases, sudden death (vi).
