Botulinum neurotoxin treatment of palmar and plantar hyperhidrosis.

Palmar and plantar hyperhidrosis is relatively common and can have severe psychological and medical consequences for those afflicted. A multitude of treatments exist but are often inadequate especially for those with significant disease. In these cases botulinum neurotoxin provides a reliable method for reducing the symptoms and improving quality of life. Although actual administration is relatively straightforward, pain management is a crucial component that requires a mastery of several techniques. Patients have a high degree of satisfaction with botulinum neurotoxin treatment and are motivated to come back for repeat treatments, usually every 6 months.
