Loperamide associated necrotising enterocolitis

Two cases of necrotising enterocolitis (NEC) occurring in infants beyond the neonatal period were reported. They did not have any predisposing factors to NEC but both had paralytic ileus after loperamide therapy for their mild diarrhoea prior to the onset of NEC. The possible role of loperamide in the pathogenesis of NEC was discussed.
