[Digital necrosis associated with fenoxazoline poisoning. Apropos of a case and review of the literature]

Abstract

We report the case of a 53 year-old woman with paroxystic hypertension and digital ischemia. The only triggering factor was chronic intoxication by a nasal vasoconstrictor:fenoxazoline. The worsening of the lesions required amputation of the third phalanx of the 3rd and 5th finger and the pulp of the 4th finger of the left hand. The review of literature exhibits association between fenoxazoline intoxication and paroxystic hypertension, myocardial ischemia or stroke, but association between fenoxazoline intoxication and digital ischemia has never been reported. We emphasize the extreme caution necessary with the prescription and the chronic consumption of this kind of drug.
