Sweat Injections with botulinum toxin

Using local injections of botulinum toxin to alleviate the symptoms of hyperhidrosis is a promising approach. Research has shown that treating the armpits, hands, feet, and face with botulinum toxin is safe and effective. In one clinical study involving 322 patients with severe underarm sweating, 81% of the patients receiving botulinum toxin injections achieved a greater than 50% reduction in sweating. And, 50% of the patients had their excessive sweating relieved for at least 201 days (nearly 7 months).
