Background Treatment of primary focal hyperhidrosis is oftenunsatisfactory. Botulinum toxin A can stop excessive sweatingby blocking the release of acetylcholine, which mediates sympatheticneurotransmission in the sweat glands.
Methods We conducted a multicenter trial of botulinum toxinA in 145 patients with axillary hyperhidrosis. The patientshad rates of sweat production greater than 50 mg per minuteand had had primary axillary hyperhidrosis that was unresponsiveto topical therapy with aluminum chloride for more than oneyear. In each patient, botulinum toxin A (200 U) was injectedinto one axilla, and placebo was injected into the other ina randomized, double-blind manner. (The units of the botulinumtoxin A preparation used in this study are not identical tothose of other preparations.) Two weeks later, after the treatmentswere revealed, the axilla that had received placebo was injectedwith 100 U of botulinum toxin A. Changes in the rates of sweatproduction were measured by gravimetry.
Results At base line, the mean (±SD) rate of sweat productionwas 192±136 mg per minute. Two weeks after the firstinjections the mean rate of sweat production in the axilla thatreceived botulinum toxin A was 24±27 mg per minute, ascompared with 144±113 mg per minute in the axilla thatreceived placebo (P<0.001). Injection of 100 U into the axillathat had been treated with placebo reduced the mean rate ofsweat production in that axilla to 32±39 mg per minute(P<0.001). Twenty-four weeks after the injection of 100 U,the rates of sweat production (in the 136 patients in whom therates were measured at that time) were still lower than base-linevalues, at 67±66 mg per minute in the axilla that received200 U and 65±64 mg per minute in the axilla that receivedplacebo and 100 U of the toxin. Treatment was well tolerated;98 percent of the patients said they would recommend this therapyto others.
Conclusions Intradermal injection of botulinum toxin A is aneffective and safe therapy for severe axillary hyperhidrosis.
