AMER, S; HASSAN, S; SHARIFFI, M  and  CHUECA, L. QT interval prolongation associated with azithromycin/methadone combination. West Indian med. j. [online]. 2013, vol.62, n.9, pp. 864-865. ISSN 0043-3144.

This report documents the occurrence of QT prolongation in a 57-year old man, on methadone replacement therapy, treated with azithromycin for community acquired pneumonia. This case highlights a hitherto unknown drug interaction. In light of ever-increasing use of azithromycin, it is imperative that azithromycin be used with caution in patients who are already on drugs that are known to cause QT prolongation or that cause torsades de pointes.

Keywords : Azithromycin; methadone; QT prolongation; torsades depointes.
