Abstract

We present a case of neutropenia complicating methimazole therapy for Graves’ disease in a 4.7-year child. The decreasing neutrophil count encountered 8 months of starting therapy, associated with losing the maintained euthyroid state, presented with the typical manifestations of neutropenia and improved rapidly after a 24 hour discontinuation of therapy followed by changing its frequency with the same dose.
