BOTOX® injections can also be effectively used to treat this social inconvenience, avoiding the need for major surgery. It takes about 10-30 minutes to perform the injection depending on site, with no down time. Results vary but generally last 6 months.
It is reassuring that anecdotal evidence suggests that repeat treatments may have a permanent effect in reducing sweat activity.
Most patients find that the injections only cause a mild sting lasting seconds. A topical numbing cream may be applied prior to the injection for a more comfortable treatment experience.
Good results can usually be obtained after a single injection. This effect generally lasts between 3 - 6 months, depending on the initial skin condition and area treated. Repeat treatments are usually needed approximately every 3-6 months over a 12 month period. It is encouraging to note that clinical trials report that some patients who have had treatment over 12 months only require further treatments once or twice the following year.
