If dose reduction is chosen for patients who experience severe neutropenia (neutrophil count less than 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 20% to 0.60 mg/ m2/ day for subsequent courses (or subsequently down to 0.45 mg/ m2/ day if necessary).
