Naphazoline poisoning associated with bradycardia and persistent hypertension: Case report

Naphazoline (NA) is an α-adrenergic agonist derived from imidazoline. Due to its vasoconstrictor action, it is widely used as a nasal decongestant with a rapid onset of action. It presents few studies on its side effects, with most case studies of accidental ingestion in children under two years of age. We report a case on the relationship between NA intoxication and symptomatic bradycardia, reversed after administration of intravenous Naloxone, in a young adult patient.
