DOSAGE AND ADMINISTRATION
Note:
Plastic devices made of acrylic or ABS (a polymer composed of acrylonitrile, butadiene, and styrene) have been reported to crack and leak when used with undiluted etoposide injection. Etoposide Injection The usual dose of etoposide injection in testicular cancer in combination with other approved chemotherapeutic agents ranges from 50 to 100 mg/m 2 /day on days 1 through 5 to 100 mg/m 2 /day on days 1, 3, and 5.
In small cell lung cancer, the etoposide injection dose in combination with other approved chemotherapeutic drugs ranges from 35 mg/m 2 /day for 4 days to 50 mg/m 2 /day for 5 days. For recommended dosing adjustments in patients with renal impairment see PRECAUTIONS section.
Chemotherapy courses are repeated at 3- to 4-week intervals after adequate recovery from any toxicity. The dosage should be modified to take into account the myelosuppressive effects of other drugs in the combination or the effects of prior x-ray therapy or chemotherapy which may have compromised bone marrow reserve.
Administration Precautions As with other potentially toxic compounds, caution should be exercised in handling and preparing the solution of etoposide injection. Skin reactions associated with accidental exposure to etoposide injection may occur.
The use of gloves is recommended. If etoposide injection solution contacts the skin or mucosa, immediately and thoroughly wash the skin with soap and water and flush the mucosa with water. 4 mg/mL. 4 mg/mL, precipitation may occur. Hypotension following rapid intravenous administration has been reported, hence, it is recommended that the etoposide injection solution be administered over a 30- to 60-minute period.
A longer duration of administration may be used if the volume of fluid to be infused is a concern. Etoposide injection should not be given by rapid intravenous injection. Parenteral drug products should be inspected visually for particulate matter and discoloration (see DESCRIPTION section) prior to administration whenever solution and container permit.
Stability Unopened vials of etoposide injection are stable until the date indicated on the package at room temperature (25°C). 4 mg/mL are stable for 96 and 24 hours, respectively, at room temperature (25°C) under normal room fluorescent light in both glass and plastic containers.
ADVERSE REACTIONS
The following data on adverse reactions are based on both oral and intravenous administration of etoposide injection as a single agent, using several different dose schedules for treatment of a wide variety of malignancies. Hematologic Toxicity Myelosuppression is dose related and dose limiting, with granulocyte nadirs occurring 7 to 14 days after drug administration and platelet nadirs occurring 9 to 16 days after drug administration.
Bone marrow recovery is usually complete by day 20, and no cumulative toxicity has been reported. Fever and infection have also been reported in patients with neutropenia. Death associated with myelosuppression has been reported. The occurrence of acute leukemia with or without a preleukemic phase has been reported rarely in patients treated with etoposide injection in association with other antineoplastic agents (see WARNINGS section).
Gastrointestinal Toxicity Nausea and vomiting are the major gastrointestinal toxicities. The severity of such nausea and vomiting is generally mild to moderate with treatment discontinuation required in 1% of patients. Nausea and vomiting can usually be controlled with standard antiemetic therapy.
Mild to severe mucositis/esophagitis may occur. Gastrointestinal toxicities are slightly more frequent after oral administration than after intravenous infusion. Hypotension Transient hypotension following rapid intravenous administration has been reported in 1% to 2% of patients.
It has not been associated with cardiac toxicity or electrocardiographic changes. No delayed hypotension has been noted. To prevent this rare occurrence, it is recommended that etoposide injection be administered by slow intravenous infusion over a 30- to 60-minute period.
If hypotension occurs, it usually responds to cessation of the infusion and administration of fluids or other supportive therapy as appropriate. When restarting the infusion, a slower administration rate should be used. 7% to 2% of patients receiving intravenous etoposide injection and in less than 1% of the patients treated with the oral capsules.
WARNINGS
Patients being treated with etoposide injection must be frequently observed for myelosuppression both during and after therapy. Myelosuppression resulting in death has been reported. Dose-limiting bone marrow suppression is the most significant toxicity associated with etoposide injection therapy.
Therefore, the following studies should be obtained at the start of therapy and prior to each subsequent cycle of etoposide injection: platelet count, hemoglobin, white blood cell count, and differential. The occurrence of a platelet count below 50,000/mm 3 or an absolute neutrophil count below 500/mm 3 is an indication to withhold further therapy until the blood counts have sufficiently recovered.
Physicians should be aware of the possible occurrence of an anaphylactic reaction manifested by chills, fever, tachycardia, bronchospasm, dyspnea, and hypotension. Higher rates of anaphylactic-like reactions have been reported in children who received infusions 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 (see ADVERSE REACTIONS section). Treatment is symptomatic. The infusion should be terminated immediately, followed by the administration of pressor agents, corticosteroids, antihistamines, or volume expanders at the discretion of the physician.
For parenteral administration, etoposide injection should be given only by slow intravenous infusion (usually over a 30- to 60-minute period) since hypotension has been reported as a possible side effect of rapid intravenous injection.
Pregnancy Etoposide Injection can cause fetal harm when administered to a pregnant woman. Etoposide has been shown to be teratogenic in mice and rats. 6 mg/kg/day (about 1/7 th and 1/2 of human dose on a mg/m 2 basis) resulted in 90 and 100% embryonic resorptions.
CONTRAINDICATIONS
Etoposide injection is contraindicated in patients who have demonstrated a previous hypersensitivity to etoposide or any component of the formulation.

Procedures for proper handling and disposal of anticancer drugs should be considered. Several guidelines on this subject have been published. 1-8 There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate.
These reactions have usually responded promptly to the cessation of the infusion and administration of pressor agents, corticosteroids, antihistamines, or volume expanders as appropriate; however, the reactions can be fatal. Hypertension and/or flushing have also been reported.
Blood pressure usually normalizes within a few hours after cessation of the infusion. Anaphylactic-like reactions have occurred during the initial infusion of etoposide injection. Facial/tongue swelling, coughing, diaphoresis, cyanosis, tightness in throat, laryngospasm, back pain, and/or loss of consciousness have sometimes occurred in association with the above reactions.
In addition, an apparent hypersensitivity-associated apnea has been reported rarely. Rash, urticaria, and/or pruritus have infrequently been reported at recommended doses. At investigational doses, a generalized pruritic erythematous maculopapular rash, consistent with perivasculitis, has been reported.
Alopecia Reversible alopecia, sometimes progressing to total baldness, was observed in up to 66% of patients. Other Toxicities The following adverse reactions have been infrequently reported: abdominal pain, aftertaste, constipation, dysphagia, asthenia, fatigue, malaise, somnolence, transient cortical blindness, optic neuritis, interstitial pneumonitis/pulmonary fibrosis, fever, seizure (occasionally associated with allergic reactions), Stevens-Johnson syndrome, and toxic epidermal necrolysis, pigmentation, and a single report of radiation recall dermatitis.
Hepatic toxicity, generally in patients receiving higher doses of the drug than those recommended, has been reported with etoposide injection. Metabolic acidosis has also been reported in patients receiving higher doses. Reports of extravasation with swelling have been received postmarketing.
Rarely extravasation has been associated with necrosis and venous induration. The incidences of adverse reactions in the table that follows are derived from multiple data bases from studies in 2,081 patients when etoposide injection was used either orally or by injection as a single agent.

In mice, a single 1 mg/kg (1/16 th of human dose on a mg/m 2 basis) dose of etoposide administered intraperitoneally on days 6, 7, or 8 of gestation caused embryotoxicity, cranial abnormalities, and major skeletal malformations. P. 5 mg/kg (about 1/10 th of human dose on a mg/m 2 basis) on day 7 of gestation caused an increase in the incidence of intrauterine death and fetal malformations and a significant decrease in the average fetal body weight.
Women of childbearing potential should be advised to avoid becoming pregnant. If this drug is used during pregnancy, or if the patient becomes pregnant while receiving this drug, the patient should be warned of the potential hazard to the fetus.
Etoposide injection should be considered a potential carcinogen in humans. The occurrence of acute leukemia with or without a preleukemic phase has been reported in rare instances in patients treated with etoposide alone or in association with other neoplastic agents.
The risk of development of a preleukemic or leukemic syndrome is unclear. Carcinogenicity tests with etoposide injection have not been conducted in laboratory animals.
