Examining hyperhidrosis: an update on new treatments.

Primary hyperhidrosis is a debilitating condition that causes significant distress and financial burden for affected patients, triggering them to seek medical care for their excessive sweating. Once a diagnosis of primary hyperhidrosis has been established, treatment is initiated to help control sweat production and increase quality of life. While there are no current guidelines in the United States for the treatment of primary hyperhidrosis, there are International Hyperhidrosis Society guidelines that clinicians can use. Currently, a step-therapy approach with the least invasive treatments prioritized first is recommended; the patient's reported disability should also be taken into consideration when selecting a first-line treatment. This update will discuss new treatment modalities, surgical procedures, associated comorbidities, and the impact on managed care of hyperhidrosis, so clinicians can tailor therapy, improve outcomes, and increase patient satisfaction.
