By preventing the blood clots that trigger heart attack and stroke, the anticoagulant drug warfarin (CoumadinÂ®) saves countless lives. Doctors must regularly monitor patientsâ blood levels in order to prescribe a high enough dose of warfarin to prevent deadly blood clots, but not an excessive dose that could lead to fatal hemorrhage.
Background. Overdose of the oral anticoagulant warfarin (Coumadin), or drug interactions with warfarin, can lead to toxicity. Similarly, toxicity can result from exposure to superwarfarins, which are long-acting anticoagulants used in rodenticides.(See Etiology and Prognosis.).leeding is the primary adverse effect of warfarin and superwarfarin toxicity and is related to the intensity of anticoagulation, length of therapy, the patient's underlying clinical state, and use of other drugs that may affect hemostasis or interfere with warfarin metabolism.
