Uncontrollable distant effects of botulinum neurotoxin injections.

Abstract

Some dentists propose administering botulinum neurotoxin injections to treat orofacial pain. The scientific literature has documented there are dangerous uncontrollable effects of long-distance traveling of botulinum neurotoxin from the injection site. These distant effects are not technique-specific, not predictable, and cannot be controlled by the amount of neurotoxin, nor by the site administered. These uncontrollable distant effects of "off-label" botulinum neurotoxin injections, at the very least, must be thoroughly disclosed to patients.
