WHAT'S NEW
This is the first randomized controlled trial to demonstrate the efficacy of an oral agent for generalized primary hyperhidrosis. This trial used a relatively low dose of oxybutynin, which produced significant benefit while minimizing anticholinergic adverse effects.
CAVEATS
There are many situations for which anticholinergic medications are inappropriate, including use by geriatric patients and those with gastrointestinal disorders, urinary retention, or glaucoma.
CHALLENGES TO IMPLEMENTATION
Few if any challenges exist to the utilization of oxybutynin; inexpensive generic versions are widely available.
