Botulinum toxin type A [Botox] is effective and well tolerated when used in the treatment of axillary hyperhidrosis, according to results from a 52-week study presented at the 62nd Annual Meeting of the American Academy of Dermatology [Washington DC, US; February 2004]. Significant improvements in the severity of hyperhidrosis, relative to baseline, were achieved in 75% of patients after a single treatment with Botox, and in up to 85% of patients after a second treatment. Furthermore, QOL, including social, emotional and occupational function, improved markedly in patients treated with Botox."Most people don't realize that hyperhidrosis is an extremely debilitating chronic condition,"said Dr Dee Anna Glaser from Saint Louis University School of Medicine, US."As such, the results of this 52-week study... are very exciting because they mean we are that much closer to having the first truly effective, non-surgical treatment available to meet the needs of patients who suffer from primary axillary hyperhidrosis".
