Botulinum Toxin Type A (eg. BOTOX® and DYSPORT®) are commonly used brands for the treatment of sweating given by injection into the skin. They are commonly used for treating localised hyperhidrosis of the armpits (axillae). This drug has been used for many years to treat muscle spasms affecting the face, eyes and neck and for foot problems in children with cerebral palsy. It is also used widely used for cosmetic purposes.
Botulinum Toxin A injection can be used to treat for palmar (hands) or plantar (feet) hyperhidrosis. it can also be used to treat sweating on the scalp (also useful to prevent hairloss) and the forehead. The skin in these areas is sensitive, and the treatment can therefore be painful unless an anaesthetic is applied.
The treatment is not a cure for hyperhidrosis – it only provides temporary relief. It needs to be repeated every four to six months for maximum effect.
When is it used?
Botulinum Toxin A is usually considered when topical treatments such as antiperspirants, iontophoresis and medications have been unsuccessful. Botulinum Toxin A is only effective in treating small areas and is therefore not a viable option for treating generalised hyperhidrosis.
