If dose reduction is chosen for patients who experience severe neutropenia (neutrophil count < 0.5 x 109/ l) for 7 days or more, or severe neutropenia associated with fever or infection, or who have had treatment delayed due to neutropenia, the dose should be reduced by 0.25 mg/ m2/ day to 1.25 mg/ m2/ day (or subsequently down to 1.0 mg/ m2/ day if necessary)
