[How to deal with drug-induced diarrhoea].

: Diarrhoea is a frequent drug adverse event, implicating a number of different treatments. It occurs in an acute setting or even several months after the beginning of the treatment and different pathophysiological mechanisms are involved. It must be proactively suspected and promptly treated, however this diagnosis is often mentioned only after multiple diagnostic tests. In this review we aim to offer a practical approach to promptly identify drug-induced diarrhoea, recognise most common implicated drugs and establish the best clinical management.
