title: OnabotulinumtoxinA therapy for compensatory hyperhidrosis.
abstract: BACKGROUND
  Compensatory hyperhidrosis due to the treatment for focal primary hyperhidrosis can be devastating and life-altering.
  
  
  OBJECTIVE
  The purpose of this paper is to discuss use of the iodine starch test and dilute botulinum toxin to decrease compensatory hyperhidrosis over large surface areas.
  
  
  METHODS
  A large area of the trunk affected by compensatory hyperhidrosis was treated with dilute botulinum toxin therapy using a starch iodine test for localization.
  
  
  RESULTS
  The patient had exceptional results with his compensatory truncal sweating returning to normal and remaining stable for multiple months.
  
  
  CONCLUSIONS
  Treating compensatory hyperhidrosis of large surface areas with dilute botulinum toxin therapy is effective and safe.
