Results of a 10-year follow-up study of botulinum toxin A therapy for primary axillary hyperhidrosis in Australia.

ABSTRACT

Primary hyperhidrosis has a prevalence of 3-5% in the United States. It is a psychosocially disabling condition leading to low self-esteem, chronic stress and depressive symptoms. Several medical and surgical treatments exist, including botulinum toxin A, which internationally, has been shown effectively and safely to treat this condition achieving high patient satisfaction. In Australia, botulinum toxin A has been available under the Medicare benefits scheme for axillary hyperhidrosis since 2013, but efficacy and treatment satisfaction had not been evaluated. We present the results of the first Australian study on efficacy and patient satisfaction with botulinum toxin A in primary axillary hyperhidrosis with evaluation of possible prognostic factors.
