An FDA-approved formulation of botulinum neurotoxin type A has been used in the treatment of moderate to severe glabellar lines. Dr. Joel Schlessinger analyzed the long-term safety data of this injection in his article, “An analysis of the long-term safety data of repeat administrations of botulinum neurotoxin type A-ABO for the treatment of glabellar lines.” This article was originally published in the November 2009 edition of the Aesthetic Surgery Journal.

To assess the long-term safety of repeated injections of BoNTA-ABO, 1415 subjects underwent open-label retreatment for over 24 months. Patients were treated with units ranging from 50 to 80 units based on gender and muscle mass.

At the end of the study, 66% of subjects experienced at least one adverse event. Most were rated as mild or moderate. This study analyzed by Dr. Joel Schlessinger concluded that multiple cycles of treatment are well-tolerated. There was no found evidence of cumulative safety issues.
