Drug-drug:
Assess frequently for signs of infection (sore throat, temperature, cough, mental status changes), especially when nadir of granulocytopenia is expected.
Lab Test Considerations:
Monitor CBC prior to each dose and routinely during therapy. The nadir of granulocytopenia usually occurs 710 days after vinorelbine administration, and recovery usually follows within 715 days. If granulocytes <1500 cells/mm3,↓ dose or hold vinorelbine. If repeated fevers and/or sepsis occur during granulocytopenia, modify future dose of vinorelbine. May also cause mild to moderate anemia. Thrombocytopenia rarely occurs.
IV Administration:
Vinorelbine is a vesicant. If extravasation occurs, immediately stop infusion. Leave needle/cannula in place temporarily but do not flush the line. Gently aspirate extravasated solution; then remove needle/cannula. Elevate patient's extremity and apply dry warm compresses for 20 min 4 times day for 12 days. Initiate hyaluronidase antidote by injecting 16 mL (150 units/mL) into existing IV line; usual dose is 1 mL for each 1 mL of extravasated drug. If needle/cannula has been removed, inject SUBQ in a clockwise manner around area of extravasation, or administer 1 mL as five separate 0.2-mL injections SUBQ into extravasation site; may repeat several times over next 34 hr.
Advise patient to notify health care provider of fever; chills; sore throat; signs of infection; bleeding gums; bruising; petechiae; blood in urine, stool, or emesis; or mouth sores. Caution patient to avoid crowds and persons with known infections.
