Hyperhidrosis Treatment (Botulinum Toxin)

Botulinum toxin treatment for excessive sweating (hyperhidrosis) of the underarms or palms. A grid of small injections temporarily blocks the nerve signals that drive the sweat glands, which is associated with a marked reduction in localised sweating. Performed by a physician, the treatment has minimal downtime and effects that typically last several months before a repeat is needed.

Primary hyperhidrosis is sweating well beyond what the body needs to regulate temperature, most often affecting the underarms, palms or soles and frequently unresponsive to ordinary antiperspirants. Botulinum toxin treats it by temporarily interrupting the chemical signal between local nerves and the sweat glands, so the treated skin produces far less sweat for the duration of the effect. At Klinika dr Grażyny Bem the area is mapped and a series of fine, shallow injections is placed evenly across the underarm or palm; numbing can be used for the palms, which are more sensitive. A session takes around thirty to forty-five minutes and there is little downtime, though the hands may feel tender briefly. A reduction in sweating usually becomes noticeable within a few days to a couple of weeks and commonly lasts several months — often longer for the underarms than the palms — after which the treatment can be repeated. It is well suited to adults troubled by underarm or palm sweating that affects clothing, grip or confidence. The doctor reviews the pattern of sweating, excludes causes that need different management and confirms suitability and contraindications at a consultation before treatment.
