Premedicate with antihistamine and acetaminophen before 1st dose, and at dose escalations. Give by IV infusion over 2hrs. Initially 3mg daily until infusion reactions are ≤ grade 2, then increase to 10mg daily until infusion reactions are ≤ grade 2, then to maintenance 30mg/day three times per week (on alternate days); duration of therapy (including escalation): 12 weeks. Do not exceed max single dose 30mg/dose or 90mg/week. Give PCP and herpes viral prophylaxis during treatment and for at least 2 months after completion or until CD4+ count ≥200cells/µL, whichever occurs later. Dose adjustments for neutropenia and thrombocytopenia: see full labeling. Retitrate if therapy interrupted for ≥7 days.
Withhold dose for severe cytopenias (except lymphopenia); discontinue if autoimmune or recurrent/persistent severe cytopenias (except lymphopenia) develop. Monitor for infusion reactions; withhold dose if grade 3 or 4. Monitor for CMV infection during and for at least 2 months after completion. Withhold dose for serious infections and during antiviral treatment for CMV infection or confirmed CMV viremia. Obtain CBCs, platelet counts weekly, assess CD4+ counts after treatment until recovery to ≥200cells/µL. Pregnancy (Cat.C). Nursing mothers: not recommended.
