Abstract

OBJECTIVE:

We evaluated the efficacy and safety of intracutaneous injections of botulinum toxin A on severe palmar hyperhidrosis.

METHODS:

Ten patients with recalcitrant palmar hyperhidrosis were treated with intercutaneous injections of botulinum toxin A (Botox; 200 U for each hand). Patients were followed up to 23 months (mean +/- SD: 12.1 +/- 6.2 months). RESULTS Botulinum toxin significantly reduced abnormal sweating within 1 week in 100% of the patients. In six patients with a follow-up of 12 months or more the antisudorific effect lasted 12.3 +/- 5.5 months. The longest response duration was 22 months. Repeated treatment was performed in five patients with unchanged clinical efficacy. The only side-effect was tolerable pain from the intracutaneous injections in patients where a nerve block was not performed.

CONCLUSIONS:

Botulinum toxin A (200 U Botox per palm) was able to induce long-term remission in palmar hyperhidrosis without significant acute and long-term side-effects. Strictly intracutaneous injection of small volumes is recommended. So far, response to repeated treatments did not show evidence of neutralizing antibody induction.
