| Management | Caution is advised if 5-FU or any of its prodrugs (e.g., capecitabine, tegafur) are prescribed in combination with leucovorin. A lower dosage of 5-FU or the prodrug may be required. Therapy with leucovorin and fluorouracil should not be initiated or continued in patients with symptoms of gastrointestinal toxicity until such symptoms have resolved. Closely monitor patients with diarrhea until it resolves. Monitor for other potential toxicities of 5-FU such as neutropenia, thrombocytopenia, stomatitis, cutaneous reactions, and neuropathy. Patients should be instructed to avoid taking folic acid supplementation or multivitamin preparations containing folic acid without first speaking with their physician. | ||||||||
