Hyperhidrosis, or excessive sweating beyond the natural requirements of the body, is a common problem that affects approximately 3% of the world’s population. It can affect one’s social life,work and psychological well-being. It can prevent those affected from certain social activities, restrict the type and colour of clothing worn, and affect self-confidence.
A recently published article in the Dermatologic Surgery journal studied the use of a particular injectable medication, more commonly used for facial wrinkles. The name of this substance cannot be named due to TGA restrictions, but it can also be used for underarm sweating. Although, this treatment is commonly performed currently, the article formalised the treatment by studying 52 patients over the period of 4 years (from May 2001 to December 2005).
After treatment with the injections into the underarms, the patients remained asymptomatic for an interval of 3 to 14 months, with a median of 5.97 months. No significant complications were noted from this treatment modality and a total of 97% of patients were highly satisfied with the treatment.
Treatments such as these can help reduce the need for operations such as an ETS or endoscopic thoracic sympathectomy to help stop sweating. Botulinum toxin type A for localised areas such as the underarms is a safe and effective means of treating excessive sweating.
