Oxybutynin for the Treatment of Primary Hyperhidrosis: Current State of the Art.

Oxybutynin is an anticholinergic drug with an emerging role in the treatment of hyperhidrosis. Several recent studies have documented that it is effective both in focal and generalized hyperhidrosis and shows universally good response among different groups of patients regardless of age, gender, and weight. The most common adverse event is dry mouth reported by almost all patients treated. The way this might affect long-term compliance and tolerability should be better investigated in the future.
