CARABANO AGUADO, I.  y  LLORENTE OTONES, L.. Montelukast and bleeding diarrhoea: an unusual association to be considered. Rev Pediatr Aten Primaria [online]. 2010, vol.12, n.48, pp.627-631. ISSN 1139-7632.

Montelukast is a safe drug widely prescribed. As with any medical device, its use is related with some side effects, some of which are rare. We report a case of bleeding diarrhea in a four year old girl, which was resolved spontaneously after drug withdrawal. This article reviews the mechanism of action of montelukast, its indications, its most common side effects, and the evidences to suspect that a drug may be behind a certain adverse effect.

Palabras clave : Montelukast; Leukotriene; Diarrhoea; Bleeding; Side effect.
