The application of botulinum toxin or botox has shown utility in hyperhidrosis of the armpits and palms. Its mechanism of action consists in blocking the nerve transmission in the neuromuscular junction, stopping the production of sweat between the second and fourth day after the infiltration.

Treatment with botulinum toxin for excessive sweating is easy to apply, with minimal side effects and high effectiveness in patients with focal primary hyperhidrosis.

The procedure is usually performed under local anesthesia by cooling the area or topical anesthesia. A decrease in the amount of sweat in the treated area is observed progressively in 1-2 weeks.

The duration of the effect achieved is variable, ranging from 6-8 months. The treatment can be repeated after this time, whenever necessary.
