This letter to the editor reports the poisoning of a sibling of a pediatric patient treated with purinethol (6MP) for the maintenance phase of the treatment of an acute lymphoblastic leukemia. Outcome was favourable but it illustrates the urge to develop preventive policies in order to avoid accidental poisoning among children treated at home with oral anticancer molecules through metronomic protocols (or target therapies) Primary prevention with anticipatory guidance should be systematically given by a physician/pharmacist stressing appropriate storage, ways of administrations and prompt medical attention in case of overdose. One should also consider restricting the quantity of anticancer agents prescribed especially when young siblings are present at home
