Drug-Drug interactionMyelosuppression may be ↑ by sodium salicylate, tolbutamide, sulfamethizole, other antineoplastics, or radiation therapy.
Route/DosageSeveral regimens have been used. These are examples
Intravenous (Children) Teniposide 165 mg/m2 in combination with cytarabine 300 mg/m2 twice weekly for 8–9 doses. Another regimen uses teniposide 250 mg/m2 in combination with vincristine 1.5 mg/m2 weekly for 4–8 wk with prednisone 40 mg/m2/day for 28 days.
Injection: 10 mg/mL
- Monitor BP prior to and every 15 min during infusion. If hypotension occurs, stop infusion and notify health care professional. After BP is stabilized with IV fluids and supportive measures, infusion may be resumed at slower rate.
- Monitor for hypersensitivity reaction (fever, chills, pruritus, urticaria, bronchospasm, tachycardia, rash, hypotension), especially during first 60 min after start of infusion. If these signs occur, stop infusion and notify physician. Keep epinephrine, antihistamine, and resuscitative equipment close by in the event of an anaphylactic reaction.
- Monitor for bone marrow depression. Assess for bleeding (bleeding gums, bruising, petechiae, guaiac stools, urine, and emesis) and avoid IM injections and rectal temperatures if platelet count is low. Apply pressure to venipuncture sites for 10 min. Assess for signs of infection during neutropenia. Anemia may occur. Monitor for increased fatigue, dyspnea, and orthostatic hypotension.
- Monitor intake and output, appetite, and nutritional intake. Teniposide causes nausea and vomiting in up to 30% of patients. Antiemetics may be used prophylactically. Adjust diet as tolerated to help maintain fluid and electrolyte balance and nutritional status.
- Monitor infusion and infusion site frequently. Extravasation may cause tissue necrosis and/or thrombophlebitis. Occlusion of central venous access devices has occurred during 24-hr teniposide infusions in concentrations of 0.1–0.2 mg/mL.
- Lab Test Considerations: Monitor CBC and differential prior to and periodically throughout therapy. Nadirs for leukopenia and thrombocytopenia occur on days 16–18 of therapy. Recovery occurs in approximately 15 days. Notify physician or other health care professional if the leukocyte count is <1000/mm3 or if the platelet count is <75,000/mm3. Therapy may be discontinued if platelet count is <50,000/mm3 or if absolute neutrophil count is <500/mm3.
- Monitor liver function studies (AST, ALT, LDH, bilirubin) and renal function studies (BUN, creatinine) prior to and periodically throughout therapy to detect hepatotoxicity and nephrotoxicity.
- May cause ↑uric acid. Monitor levels periodically during therapy.
Potential Nursing DiagnosesRisk for injury (Side Effects)
Risk for infection (Side Effects)
- high alert: Fatalities have occurred with chemotherapeutic agents. Before administering, clarify all ambiguous orders; double check single, daily, and course-of-therapy dose limits; have second practitioner independently double check original order, dose calculations and infusion pump settings.
- Avoid contact with skin. Use Luer-Lok tubing to prevent accidental leakage. If contact with skin occurs, immediately wash skin with soap and water.
- Solution should be prepared in a biologic cabinet. Wear gloves, gown, and mask while handling medication. Discard equipment in designated containers (see ).
- Administration of live-virus vaccines to immunocompromised patients should be avoided.
- Intermittent Infusion: Diluent: Dilute with D5W or 0.9% NaCl. Concentration: Final concentration will be 0.1, 0.2, 0.4, or 1 mg/mL depending on amount of diluent added. Concentrations of 1 mg/mL should be administered within 4 hr of dilution.Concentrated teniposide is clear but may develop a slight opalescence when diluted in solution. Precipitation may occur at recommended concentrations. Solution must be prepared and administered in nonplastic equipment to prevent cracking of plastic and possible drug leakage. Glass or polyolefin plastic bags or containers should be used; PVC containers are not recommended. Diluted solutions are stable for 24 hr at room temperature. Do not refrigerate.
- Rate: Administer over 30–60 min or longer. Do not give by rapid infusion; may result in hypotension.
