Résumé
Bismuth subsalicylate releases salicylate, which can increase bleeding risk through antiplatelet effects and possible displacement of warfarin from protein binding. High or prolonged doses carry the greatest risk, and gastric irritation may add to bleeding.
Ce que signifie cette interaction, en termes simples
