title: Contact allergy to idoxuridine. Sensitization following treatment of herpes zoster.
abstract: A total of 45 of 60 patients with herpes zoster previously treated with topical idoxuridine 5-40% in dimethylsulfoxide were patch tested 2 years later with idoxuridine 0.5% and 5% in petrolatum. Three (7%) showed positive reactions. Idoxuridine is considered a weak sensitizer, but in strong concentrations and in active solvents, which increases absorption, there seems to be a risk of sensitization.
