PG - S293-S303 LID - 10.1097/DSS.0000000000001409 [doi] AB - BACKGROUND: The safety and efficacy of incobotulinumtoxinA in aesthetics has been established in multiple studies. Although individual studies have been reported, a combined assessment of incobotulinumtoxinA safety across studies is not available. OBJECTIVE: To assess the frequency of adverse events (AEs) across prospective incobotulinumtoxinA studies in aesthetics. MATERIALS AND METHODS: Safety data were assessed from 9 placebo-controlled or active-controlled single-dose studies on glabellar frown lines (GFL), crow's feet (CF), and upper facial lines (UFL). Analyses by treatment cycle included 4 repeat-dose studies on GFL and UFL. RESULTS: One thousand three hundred seventy-seven subjects received incobotulinumtoxinA (GFL, n = 1,189; CF, n = 83; UFL, n = 105) in single-dose studies (placebo-controlled studies: incobotulinumtoxinA, n = 866; placebo, n = 395). Over 1,000 subjects received incobotulinumtoxinA in repeat-dose studies (GFL, n = 880; UFL, n = 290). In placebo-controlled single-dose studies, incidences of treatment-related AEs ranged from 5.4% (GFL) to 22.9% (UFL). The most frequent treatment-related AE in single-dose studies was headache (GFL, 4.8%; UFL, 11.4%). In repeat-dose studies, incidence of AEs was highest during cycle 1 (GFL, 8.9%; UFL, 17.2%) and decreased across treatment cycles. No serious treatment-related AEs were observed. CONCLUSION: Results confirm the favorable safety and tolerability of incobotulinumtoxinA. The frequency of treatment-related AEs was low and may decrease with subsequent treatments.
