Generic Name and Formulations:
Hydroxyurea 200mg, 300mg, 400mg; caps.
Indications for DROXIA:
To reduce the frequency of painful crises and to reduce the need for blood transfusions in adults with sickle cell anemia with recurrent moderate-to-severe painful crises.
Base dose on ideal or actual weight, whichever is less. Initially 15mg/kg/day as a single dose. May increase dose by 5mg/kg/day every 12 weeks to maximum tolerated dose or 35mg/kg/day achieved; do not increase dose if blood counts are between acceptable and toxic range. If blood counts toxic, discontinue until hematologic recovery, see full labeling for dosage adjustments. Renal impairment (CrCl <60mL/min or ESRD): initially 7.5mg/kg/day; give dose following dialysis (monitor).
Risk of severe myelosuppression. Monitor blood counts at baseline and during therapy; interrupt or reduce dose if necessary. Markedly depressed bone marrow function: do not initiate. Monitor for malignancies. Avoid sun exposure. Macrocytosis may mask folic acid deficiency; prophylactic folic acid is recommended. Myeloproliferative disorders; discontinue if cutaneous vasculitic ulcerations occur. Obtain fetal hemoglobin (HbF) levels every 3–4 months; may be used to assess efficacy. Renal or hepatic impairment. Elderly. Embryo-fetal toxicity. Pregnancy; avoid. Exclude pregnancy prior to initiating; use effective contraception during and for ≥6 months (females) or ≥1 year (males) after therapy. Nursing mothers: not recommended.
Avoid concomitant didanosine, with or without stavudine, or other antiretrovirals (may cause pancreatitis [monitor], fatal hepatotoxicity, peripheral neuropathy). Avoid live vaccines. Increased risk of vasculitic toxicities with interferon therapy. May cause falsely elevated results in urea, uric acid, and lactic acid assays.
Leukopenia, thrombocytopenia, anemia, neutropenia, GI upset, anorexia, hair loss, macrocytosis, bleeding, melanonychia; secondary malignancies.
