Overdose Information
Overdose Symptoms:
- Severe myelosuppression (e.g., profound neutropenia, thrombocytopenia)
- Severe peripheral neuropathy
- Paralytic ileus
- Severe hepatic dysfunction
What to Do:
There is no known antidote for vinorelbine overdose. Management is supportive, including close monitoring of hematologic parameters, administration of growth factors (e.g., G-CSF) for neutropenia, management of neurological symptoms, and aggressive bowel regimen for ileus. Call 1-800-222-1222 (Poison Control Center) or seek immediate medical attention.
Drug Interactions
Major Interactions
- Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, grapefruit juice): May significantly increase vinorelbine plasma concentrations, leading to increased toxicity (e.g., myelosuppression).
- Live vaccines: Risk of severe or fatal infection in immunocompromised patients.
Moderate Interactions
- Strong CYP3A4 inducers (e.g., rifampin, phenytoin, carbamazepine, St. John's Wort): May decrease vinorelbine plasma concentrations, potentially reducing efficacy.
- Other myelosuppressive agents (e.g., other chemotherapies, radiation therapy): Increased risk of severe myelosuppression.
- Paclitaxel: Concurrent administration may increase risk of neurotoxicity and myelosuppression (administer vinorelbine first if given sequentially).
- Cisplatin: May increase vinorelbine exposure when given in combination.
Minor Interactions
- Warfarin: Potential for altered INR, monitor closely.
Monitoring
Baseline Monitoring
Rationale: To assess baseline bone marrow function and identify pre-existing cytopenias, as myelosuppression is a dose-limiting toxicity.
Timing: Prior to initiation of therapy.
Rationale: Vinorelbine is extensively metabolized by the liver; hepatic impairment necessitates dose adjustment.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline kidney function, though renal excretion is minor, caution is advised in severe impairment.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline neurological status, as peripheral neuropathy is a common side effect.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Weekly (prior to each dose)
Target: Absolute Neutrophil Count (ANC) ≥ 1500 cells/mm³; Platelets ≥ 100,000 cells/mm³
Action Threshold: If ANC < 1500 cells/mm³ or platelets < 100,000 cells/mm³, delay dose until recovery. Consider dose reduction for subsequent doses if prolonged or severe myelosuppression occurs.
Frequency: Periodically, or as clinically indicated (e.g., every 3-4 weeks or with dose adjustments)
Target: Within acceptable limits for dosing
Action Threshold: If bilirubin >2 mg/dL or AST/ALT >2x ULN, consider dose reduction or delay.
Frequency: Prior to each dose and as clinically indicated
Target: No new or worsening signs of peripheral neuropathy
Action Threshold: If moderate to severe peripheral neuropathy develops, consider dose reduction or discontinuation.
Frequency: Daily patient inquiry
Target: Regular bowel movements
Action Threshold: If constipation develops, initiate prophylactic laxatives; if severe, consider dose delay or reduction.
Symptom Monitoring
- Fever (especially with chills or other signs of infection)
- Unusual bleeding or bruising
- Numbness, tingling, or weakness in hands or feet (peripheral neuropathy)
- Severe constipation or abdominal pain
- Shortness of breath or cough
- Pain or redness at injection site (extravasation)
- Fatigue, dizziness
Special Patient Groups
Pregnancy
Vinorelbine can cause fetal harm when administered to a pregnant woman. It is classified as Pregnancy Category D. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 3 months after the last dose.
Trimester-Specific Risks:
Lactation
It is not known whether vinorelbine is excreted in human milk. Because of the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment with vinorelbine and for 3 months after the last dose.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established. Limited data suggest that vinorelbine is not effective in pediatric solid tumors and may cause significant toxicity.
Geriatric Use
Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. However, elderly patients may be more susceptible to myelosuppression and neurotoxicity. Careful monitoring of hematologic parameters and neurological status is recommended.
Clinical Information
Clinical Pearls
- Vinorelbine is a vesicant; ensure proper IV access and monitor for extravasation. If extravasation occurs, stop infusion immediately, aspirate residual drug, and consider local hyaluronidase injection.
- Myelosuppression, particularly neutropenia, is the dose-limiting toxicity. Weekly CBC monitoring is crucial.
- Constipation is a common and potentially severe side effect; prophylactic laxatives (e.g., stool softeners, stimulant laxatives) should be initiated at the start of therapy.
- Peripheral neuropathy is cumulative and can be dose-limiting. Monitor for symptoms like numbness, tingling, and weakness.
- Administer vinorelbine over 6-10 minutes into the side port of a free-flowing IV line, followed by a flush, to minimize vein irritation and extravasation risk.
- Do not administer intrathecally; intrathecal administration of vinca alkaloids is fatal.
Alternative Therapies
- Other vinca alkaloids (e.g., Vincristine, Vinblastine)
- Taxanes (e.g., Paclitaxel, Docetaxel) for NSCLC or breast cancer
- Pemetrexed (for NSCLC)
- Gemcitabine (for NSCLC)
- Platinum-based chemotherapy (e.g., Cisplatin, Carboplatin)
- Targeted therapies or immunotherapies depending on specific cancer type and molecular profile.
