Abstract

PURPOSE OF THE REVIEW:

The role of onabotulinumtoxinA in headache management was serendipitously found over a decade ago and approved for chronic migraine in 2010 based on pivotal studies. The purpose of this review is to highlight the impact on headache and other health parameters which is critically reviewed, as well as the putative mechanisms of action.

RECENT FINDINGS:

OnabotulinumtoxinA is effective in migraine, not only headache frequency and pain intensity but also other health parameters including quality of life. Tolerability is high and benefit/cost analysis is favorable. It should be considered off-label in refractory trigeminal neuralgia and post-herpetic neuralgia but further research in these areas. Ongoing investigation of onabotulinumtoxinA in cluster headache is too preliminary for recommendation of use but promising. Recent and future developments in other headache disorders are discussed. OnabotulinumtoxinA has been approved for migraine almost a decade ago and been proven beneficial not only on headache parameters but other health outcomes. Its role as adjuvant is being studied and emerging in other headache syndromes.
