Injections of IncobotulinumtoxinA at Intervals Less Than 10 weeks Are Effective and Safe for Cervical Dystonia Patients With Inadequate Benefit From Standard Injection Intervals

Background:Efficacy and safety of two incobotulinumtoxinA injection schedules for treating cervical dystonia (CD) were compared. Some CD patients receiving long-term botulinum toxin (BoNT) therapy report early waning of treatment effect (even after favorable peak response) before a typical 3-month reinjection interval. This study addresses the safety and efficacy of incobotulinumtoxinA injection intervals <10 weeks.
