Rapid oral desensitisation procedure in clopidogrel hypersensitivity.

We describe a patient who developed generalised pruritus with oedema and rash two weeks after she had started taking clopidogrel following coronary stent implantation. In the absence of other likely causative agents, clopidogrel hypersensitivity was probable. She was treated with a rapid oral desensitisation procedure, after which a daily dose of 75 mg clopidogrel was well tolerated. No major adverse events occurred during a follow-up period of eight months. Oral desensitisation in clopidogrel hypersensitivity seems to be a safe method to reduce the risk of coronary stent thrombosis. (Neth Heart J 2008;16:21-3.).
