Botulinum Toxin for Excessive Sweating (Hyperhidrosis)

Botulinum toxin treatment for hyperhidrosis (excessive sweating) of the underarms, palms or soles, performed personally by plastic surgeon Prim. MUDr. Inka Třešková. A short outpatient session of superficial micro-injections reduces sweat-gland activity in the treated area, with the effect appearing within 2–5 days and lasting on average around half a year.

Hyperhidrosis — uncontrolled, excessive sweating of the underarms, palms, soles or other areas — can cause significant social stress that resists antiperspirants and lifestyle measures. Botulinum toxin offers a highly effective, low-risk solution: injected superficially into the affected skin, it blocks the nerve signals that drive the sweat glands, sharply reducing sweat production in the treated area. The procedure at this practice is a quick, uncomplicated outpatient treatment lasting only a few minutes. The skin is ideally hair-free for the application; a numbing cream can be applied beforehand for comfort. After disinfection, the active substance is injected in a fine grid across the affected area. The effect develops within approximately 2 to 5 days. Results are temporary, which also makes the treatment easy to trial: depending on individual disposition the reduction in sweating lasts 4 to 12 months (on average about half a year), and with regular repeat treatments the effect typically lasts progressively longer. Side effects are uncommon — small bruises at injection points in the underarm area, or rare, short-lived changes in sensation when palms or soles are treated. For several days after the treatment, intense sport, sauna and solarium should be postponed. The treatment is not suitable during pregnancy or breastfeeding, with certain neuromuscular disorders, or alongside certain antibiotics — contraindications are reviewed at the free consultation with Dr Třešková.
