Patients affected by these chemotherapeutics present with significant clinical toxicities that are potentially fatal. Clinicians must recognize these patients early and be prepared to provide immediate interventions that include specific antidotal therapies. The oral formulations of methotrexate and capecitabine present a risk for intentional or unintentional chemotherapeutics ingestion in the home.
