    Dosage

    Due to the complexity and specialist nature of dosage regimens for the treatment of malignant disease, specific dosing information on this agent is not included.
    Doses may vary significantly if this agent is used as monotherapy or different combinations.
    When using this agent, specialist literature, national guidelines, cancer network protocols and Trust chemotherapy protocols should be consulted.

    Patients with Renal Impairment

    Creatinine clearance 15 to 50ml/minute: Initial dose should be reduced to 75% of the initial recommended dose.

    Creatinine clearance less than 15ml/minute: Manufacturer suggests a further dose reduction based on tolerance and clinical effect.

    The Renal Drug Handbook suggests the following reductions:
    GFR 60ml/minute: 85% of normal dose
    GFR 45 to 60ml/minute: 80% of normal dose
    GFR 30 to 45ml/minute: 75% of normal dose
    GFR less than 30ml/minute: 50% of normal dose, based on clinical response

    Administration

    For slow intravenous infusion, between 30 and 60 minutes

    Reduce dose if neutrophils < 0.5 x 10 to the power 9/L with fever/infection
    Suspend treatment if leucocytes fall below 2,000/cubic mm
    Reduce dose if platelets <25 x 10 to the power of 9/L
    Male & female: Contraception required during & for 6 months after treatment

    Acute leukaemia, which can occur with or without a preleukaemic phase, has been reported rarely in patient treated with etoposide in combination with other anti-neoplastic drugs. The predisposing factors have not been identified.

    A new treatment cycle should only be started if neutrophil count is greater than 1.5 x 10 to the power of 9/L and platelet count is greater than 100 x 10 to the power 9/L unless caused by malignant disease.

    If severe reactions occur the dose should be reduced or discontinued and appropriate corrective measures initiated. Re-initiation of etoposide should be carried out with caution and consideration to the risks versus the benefits.

    Pregnancy and Lactation

    Pregnancy

    Etoposide is contraindicated during pregnancy.

    Growth restriction and severe myelosuppression has been observed in newborns of pregnant women using etoposide during the 2nd and 3rd trimester.

    Studies in rats and mice have shown teratogenic effects.

    The effects of concurrent therapies must also be considered.

    The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( www.toxbase.org ) or if this is unavailable at the backup site ( www.toxbasebackup.org ).

    Lactation

    Etoposide is contraindicated in breastfeeding.

    Etoposide is excreted into human breast milk and there is a potential for severe toxicity in the nursing infant. Briggs suggests that breastfeeding should be stopped for at least 55 hours after the last dose of etoposide, based on its half life, while Schaefer suggests 24 to 36 hours.

    The effect of concurrent therapies must also be considered.

    Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
