Botulinum toxin has been used for decades in the treatment of a variety of painful diseases. Botulinum toxin not only blocks neuromuscular transmission, but also the secretion of neuropeptides, such as substance P, glutamate and calcitonin gene-related peptide (CGRP) and thus inhibits neurogenic inflammation. ⋯ In addition, botulinum toxin is also recommended in guidelines as a third-line treatment for neuropathic pain, but in Germany this is an off-label application. This article provides an overview of the current clinically relevant areas of application of botulinum toxin in the field of pain medicine.
