Preparing cancer patients to administer medication.

Leucovorin calcium is given to cancer patients receiving high-dose methotrexate to retard the onset of serious side effects. Precise adherence to dose and schedule is essential, and it is necessary that patients who self-administer their drug know how to open the ampules and withdraw the correct amount without wastage. Educational resource materials were developed to be given to patients when the leucovorin calcium was dispensed.
