We report a case of a 34-month-old girl who has been followed up for 12 months after ingesting 105mg/kg of hydroxyurea (HU) and showed only transient mild bone marrow suppression. With anticipated increase in HU use among children with SCD in sub-Saharan Africa, the possibility of accidental ingestion should be envisaged and appropriate user-education and management guidelines established. Toxicity from accidental HU overdosage is generally mild and transient and should not constitute a barrier to its use in Nigerian children with SCD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
