OBJECTIVE: We evaluated the efficacy of subepidermal injections of botulinum toxin type A on recalcitrant palmar and digital hyperhidrosis.
METHODS: Twenty patients with recalcitrant palmar and digital hyperhidrosis were treated with subepidermal injections of botulinum toxin. Nineteen patients completed the 12-month study. Injections were performed in 3 stages. The total dose of toxin for each hand, which included the palm, thenar eminence, and digits, was 165 units. Patients were followed up on a monthly basis.
RESULTS: Botulinum toxin significantly reduced sweat production in the treated areas. Anhidrosis lasted 9 months in 3 patients, 8 months in 3 patients, 7 months in 8 patients, 6 months in 3 patients, 5 months in 1 patient, and 4 months in 1 patient. Reduced sweating of the palm and digits continued in all patients for the 12-month evaluation period, with the greatest reduction of sweating in the nondominant hand. Mild weakness of the thumb occurred in 4 patients at a mean duration of 3 weeks, with the greatest duration being 6 weeks.
CONCLUSION: Botulinum toxin provides a safe and efficacious alternative in the treatment of recalcitrant palmar and digital hyperhidrosis.
