Severe reaction to hydroxyurea.
This case illustrates the danger of Hydrea taken for more than three years, even though results of monthly blood studies and platelet counts were within normal limits. In this patient, thrombocytopenia suddenly developed only five weeks after normal laboratory results. Fortunately, the sodium level reverted to normal and the pancytopenia disappeared within a week with no residual effects.
