Induction of Tolerance to Warfarin after Anaphylaxis with a Desensitization Protocol

摘要

Warfarin hypersensitivity is exceedingly rare. A 59-year-old male with acute renal infarction and a history of allergy to warfarin underwent evaluation, confirming presence of warfarin hypersensitivity. Induction of tolerance to warfarin was successfully completed using an oral desensitization protocol, which has not previously been reported.
