With Hydroxycarbamide constant at 500 mg five days a week for the last two months Platelets have risen above normal limits (thrombocythaemia) carrying a risk of blood clots; Hb is stable at a point just above the level where transfusion might be indicated. Low haemoglobin causes fatigue. If it falls below 100, the prognosis given by DIPSS+ is affected, but UK clinicians never refer to it.

The dose is to be kept the same for the next four weeks.
