- Withhold further treatment if platelet is less than 50,000/mm³ or ANC less than 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 the 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 the 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 the 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
- The prescriber must consider benefits versus risk of therapy; if severe reactions occur, the dose should be reduced or discontinued and appropriate corrective measures are taken; reinstitution of therapy should be carried out with caution and with adequate consideration of the 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
- Anaphylactic reaction manifested by chills, fever, tachycardia, bronchospasm, dyspnea, and hypotension reported; higher rates of anaphylactic-like reactions reported in children who received infusions of etoposide at concentrations higher than those recommended; the role that concentration of infusion (or rate of infusion) plays in the development of anaphylactic-like reactions is uncertain; treatment is symptomatic; infusion should be terminated immediately, followed by administration of pressor agents, corticosteroids, antihistamines, or volume expanders at the discretion of the physician
- Reversible cases of acute renal failure reported with administration of high dose (2220 mg/m²) with total body irradiation used for hematopoietic stem cell transplantation; the formulation contains dextran 40, which has been associated with acute renal failure when administered in high doses
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 the potential hazard to a fetus; advise women of childbearing potential to avoid becoming pregnant
- Advise females of reproductive potential to use effective contraception during treatment and for 6 months after final dose In females of reproductive potential, may cause infertility and result in amenorrhea; premature menopause can occur; recovery of menses and ovulation is related to age at treatment
- There is no information regarding the presence of etoposide in human milk or its effects on breastfed infant milk production; because of the potential for serious adverse reactions in nursing infants, advise women not to breastfeed during treatment with etoposide
