The Treatment of Primary Focal Hyperhidrosis

Primary focal hyperhidrosis is a relatively common disease that has a significant impact on afflicted patient’s quality of life. The pathogenesis of the disease is thought to stem from increased cholinergic activity on eccrine sweat glands. Topical aluminum chloride based antiperspirants are good first-line agents for all affected body sites. Anticholinergic agents are emerging as effective topical alternatives. Iontophoresis passes an electrical current through the skin and is an excellent treatment option for palmoplantar disease. Botulinum toxin type A injections remain a mainstay second-line treatment. Local procedural advances including microwave thermolysis, laser therapy and focused ultrasound are emerging as safe and effective alternatives for refractory disease. Oral anticholinergics are generally well tolerated and can also be used for intractable disease. Last-line interventions include local surgical options and sympathectomy, though some patients may prefer permanent treatment. Further investigation of novel treatments as well as ways to optimize existing therapeutic options are needed.
