A woman treated with mitoxantrone, etoposide and cytarabine for promyelocytic leukemia received 3 daily mitoxantrone doses of 6 mg/sq m intravenously. A mitoxantrone milk level of 120 mcg/L occurred immediately after the third dose. Milk mitoxantrone level dropped to a plateau value of about 20 mcg/L by 7 days after the third dose and remained at 18 mcg/L at 28 days after the last dose.[1]
