GENERALLY AVOID: Salicylates may interfere with the renal elimination of methotrexate and may displace it from binding sites. The pharmacologic effect and toxicity of methotrexate may be increased. Patients receiving high-dose methotrexate are at a greater risk of developing toxicity.

MANAGEMENT: If these agents must be used concomitantly, caution should be exercised and the patient should be monitored closely for signs and symptoms of bone marrow suppression and nephrotoxicity. Patients should be advised to report possible symptoms of toxicity including nausea, vomiting, diarrhea, stomatitis, sore throat, chills, fever, rash, unusual bruising or bleeding, jaundice, dark urine, swelling of the extremities, or shortness of breath to their physician. Patients should also be counseled to avoid any other over-the-counter salicylate products.
