Abstract

A 25-year-old woman developed generalized urticaria and an anaphylactic syndrome of sudden onset while she was being treated for her decubitus ulcer with chlorhexidine antiseptic solution.
Prick test with 0.5% chlorhexidine produced a wheal in a few minutes.
A passive intradermal transfer test (PK test) to her mother was positive. These enabled us diagnose her as having an immunologic contact urticaria to chlorhexidine.

Keywords: Immunologic contact urticaria, Chlorhexidine
