Abstract
Hyperhidrosis is the excessive
production of
sweating, which can be primary and focal or
secondary to various
pathologies. The exact cause of primary focal
hyperhidrosis is still unknown, although a genetic basis is recognized, and its
prevalence varies from 1% to 2.8%. The most affected sites are the armpits, palms, soles and
face. It causes much discomfort,
affects the
quality of life, and is estimated to be undervalued by
health professionals. Many
treatment options are proposed, both clinical and surgical. The aim of this
review is to focus on the
treatment of
hyperhidrosis with oxybutynin, an
anticholinergic drug originally used to control
overactive bladder.
