title: Recurrent pseudo-scarlatina and allergy to pseudoephedrine hydrochloride.
abstract: A case of recurrent pseudo-scarlatina is described. Challenge with pseudoephedrine hydrochloride reproduced a typical attack but pseudoephedrine ingestion could not be related definitely to all episodes. Allergy to pseudoephedrine or codeine should be considered as a cause for recurrent scarlet fever-like eruptions.
