Botulinum toxin acts in a way that it temporarily blocks the conductivity of chemical nerve signals for stimulation of sweat glands. It is efficient with hyperhidrosis – excessive sweating – in most of the patients. The treatment takes about an hour; after that, all regular daily activities are allowed. It is important to emphasize that this treatment does not cure the problem of hyperhidrosis, but eliminates excessive sweating, lasting up to 6 months. After a couple of months, a person can expect relapse, and if necessary, the treatment can be repeated. Such procedure is sufficient twice a year for most of the people.
