            Warnings

            Black Box Warnings

            The drug should be administered under the supervision of an experienced cancer chemotherapy physician

            Severe myelosuppression, which could result in bleeding and infection, may occur

            Contraindications

            Hypersensitivity to etoposide or teniposide

            Cautions

            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

            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 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

            Pregnancy & Lactation

            Pregnancy Category: D

            Lactation: not known if excreted in breast milk, discontinue drug or do not nurse

            Pregnancy Categories

            A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA:Information not available.

            IV Preparation

            VePesid, Toposar & equivalents

            • Concs >0.4 mg/mL are very unstable
            • Lower dose regimens (<1 g/dose): doses may be diluted in 100-1000 mL of D5W or NS
            • High dose regimens (>1 g/dose): draw total dose into an empty Viaflex container & add appropriate amount of diluent for a final concentration of 1 mg/mL
            • High dose, 2-Channel Pump Method Instill all of the etoposide dose into one Viaflex container for a concentration of 20 mg/mLInfuse this into one channel (any 2-channel infusion pump that does not require a hard plastic cassette)Infuse indicated diluent (D5W or NS) at least 20x infusion rate of etoposide to simulate a 1 mg/mL concentration in the lineEtoposide should be Y-sited into the port most proximal to ptAttach 0.22 micron filter to line after Y-site & before entry into pt

            Etopophos

            • Reconstitute to 10-20 mg/mL with any one of: D5W; NS; SWI; BWI; bacteriostatic NS
            • May be further diluted down to 0.1 mg/mL with NS or D5W
