Only Botox is currently FDA approved for the treatment of focal hyperhidrosis. The axilla (armpits) are one of the most common areas to treat for excessive sweating. This labeling becomes important only for collecting insurance reimbursement, as many patients can get covered for this procedure if the hyperhidrosis is severe enough.All three, Botox, Xeomin, and Dysport will work, but Xeomin and Dysport are not FDA labeled for this use. So in my opinion, it would be a waste of time to try to bill any insurance company for a treatment with Xeomin or Dysport; whereas Botox will often be a covered procedure.If the patient doesn't have insurance for this problem, and they are self paying, they most certainly should be able to use either Xeomin or Dysport and be charged less than if it were Botox. They would just need to find a Board Certified Dermatologist who does enough of these kind of treatments to be able to do that.
