Warnings
Therapy causes myelosuppression that results in thrombocytopenia and neutropenia; fatalinfections and bleeding have occurred; obtain complete blood counts prior to each cycle and more frequently as clinically indicated; withhold further treatment if platelet <50,000/mm³ or ANC <500/mm³
Use caution in hepatic impairment
Do NOT inject rapidly (may cause hypotension); infuse over at least 30-60 min
Injection site reactions may occur during administration; monitor closely
Avoid pregnancy
May result in oligospermia, azoospermia, and permanent loss of fertility; sperm counts have been reported to return to normal levels in some men, and in some cases has occurred several years after end of therapy; may damage spermatozoa and testicular tissue, resulting in possible genetic fetal abnormalities; males with female sexual partners of reproductive potential should use condoms during therapy and for at least 4 months after final dose
May cause infertility in females of reproductive potential and result in amenorrhea; premature menopause can occur; recovery of menses and ovulation is related to age at treatment; advise females of reproductive potential to use effective contraception during treatment for at least 6 months after final dose
Occurrence of acute leukemia with or without a preleukemic phase reported in rare instances in patients treated with etoposide alone or in association with other neoplastic agents; risk of development of preleukemic or leukemic syndrome unclear
Prescriber must consider benefits versus risk of therapy; if severe reactions occur, dose should be reduced or discontinued and appropriate corrective measures taken; reinstitution of therapy should be carried out with caution, and with adequate consideration of further need for drug and alertness as to possible recurrence of toxicity
Patients with low serum albumin may be at increased risk for etoposide associated toxicities
Pregnancy and Lactation
Based on animal data and its mechanism of action, etoposide can cause fetal harm when administered to a pregnant woman; etoposide, the active moiety of etoposide phosphate is teratogenic in mice and rats advise pregnant women of potential hazard to a fetus; advise women of childbearing potential to avoid becoming pregnant
There is no information regarding presence of etoposide in human milk or its effects on breastfed infant milk production; because of potential for serious adverse reactions in nursing infants, advise women not to breastfeed during treatment with etoposide
