På grund af de potentielt alvorlige kliniske udfald af de kutane vaskulære ulcerationer, der blev indberettet for patienter med myeloproliferativ sygdom, skal hydroxycarbamid seponeres og/ eller dosis reduceres, hvis der opstår kutane vaskulære ulcerationer.
Due to potentially severe clinical outcomes for the cutaneous vasculitic ulcers reported in patients with myeloproliferative disease, hydroxycarbamide should be discontinued and/ or its dose reduced if cutaneous vasculitic ulcerations develop.
