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.
