Botulinum toxin for chronic pain: What's on the horizon?
Botulinum toxin has proven safe and effective when used correctly. This review examines the evidence that could support its expanded use.
PRACTICE RECOMMENDATIONS
› Consider botulinum toxin (BoNT) for patients with headache, spasticity, or cervical dystonia, as the FDA has approved BoNT for pain relief in these conditions. A
Strength of recommendation (SOR)
A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series
Adequate research and evidence for most of the applications discussed in this article are still lacking; some limitations include small sample size, bias, lower quality, and poor methodology. There is also a lack of standardization, including which BoNT product is used, dosage, and location of BoNT placement. All of these issues will need to be addressed in further research.
