Re: Changes to the QTdrugs List and List of Drugs to Avoid in cLQTS

Dear CredibleMeds Registrants:

AZCERT's Scientific Review Committee has found substantial evidence that Triclabendazole (antiparasitic) is associated with the development of QT prolongation but lacks convincing evidence of torsades de pointes (TdP).  Therefore, this drug has been added to the Possible Risk of TdP category (PR) and the List of Drugs to Avoid in patients with Congenital Long QT Syndrome (DTA List).  

As demonstrated by these revisions, the QTdrugs list is dynamic and changes regularly.  To perform a quick search of the Lists we recommend using the CredibleMeds website and the smartphone app (Apple or Android).
