Botulinum toxin (of which Botox® is the best known brand name) works by blocking the release of chemicals from the nerves that send signals from the brain to the sweat glands, thereby reducing sweating.
You may want to consider Botox® injections if specialist antiperspirants fail to work. Multiple injections are given to the area being treated and the reduction in sweat is seen soon afterwards. However, the effects are temporary as the nerve endings will regenerate and the treatment must be repeated, generally every four to six months.
When Botox® is administered to the underarm area, the procedure is considered very bearable, as it is quick and the injections relatively superficial. However, for the hands and feet, the injections tend to be a lot more painful and often some form of anaesthesia or pain relief is necessary.
Side effects of the procedure are usually temporary and can include slight bruising tenderness and muscle weakness in the hands.
Botox® is available on the NHS in a small number of UK hospitals and usually only for treatment of the underarms. This normally only applies to a select amount of patients and for a short period of time (around one year). It is available in some private hospitals and clinics for treatment under the arms and for the hands and feet. This usually costs between £300 and £700 each time.
