By: Ani Barsamian, JD

Zithromax may cause QT interval prolongation which is associated with the potentially fatal heartbeat rhythm called Torsades de Pointes (TdP). Torsades de Pointes is a type of accelerated heartbeat.  Many drugs have been recalled from the market due to the increased incidence of Torsades de Pointes.

Symptoms of Torsades de Pointes include:

  •     Palpitations
  •     Fainting
  •     Ventricular fibrillation
  •     Cardiac arrest
  •     Sudden death
