Current treatments for axillary hyperhidrosis

Primary hyperhidrosis affects up to 1% of the population and has a significant negative impact on quality of life. It affects the axillae in approximately 80% of cases. Hyperhidrosis results from excessive sympathetic stimulation of the eccrine sweat glands: the various treatment modalities available target points along the pathway between the central nervous system and the peripheral gland. The first line of treatment is topical aluminium chloride, which is effective in the majority of cases. Alternative treatments such as systemic anti-cholinergics and iontophoresis have significant disadvantages, while surgical sympathectomy has been regarded as the gold-standard in treatment of this condition. Recently, attention has focused on the use of intradermal botulinum toxin for the treatment of axillary hyperhidrosis. This is a highly effective, minimally-invasive treatment with few side effects, and is now recommended as the treatment of choice in isolated axillary hyperhidrosis
