Pediatric Visine (tetrahydrozoline) ingestion: case report and review of imidazoline toxicity.

Visine, an over-the-counter, tetrahydrozoline topical ophthalmic decongestant, possesses central and peripheral alpha2-adrenergic properties. We present a case of accidental pediatric oral exposure with resultant neurological and cardiovascular complications. Visine is not marketed in childproof containers, despite the potential severity of an accidental ingestion. Over-the-counter medications with potent pharmacological properties should be stored in areas out of the reach of children, and manufacturers should package these products in childproof containers.
