Botulinum Toxin for Excessive Sweating (Hyperhidrosis)

Botulinum toxin injected into the skin of the underarms (or other sweat-prone areas) to reduce excessive sweating, or hyperhidrosis. The toxin blocks the nerve signals that switch on the sweat glands, markedly lowering sweat production in the treated area for several months. It is a well-established option for people whose sweating is not controlled by antiperspirants.

Treatment for excessive sweating uses botulinum toxin to interrupt the nerve signals that tell the sweat glands to produce sweat. A grid of tiny, shallow injections is placed across the affected area — most commonly the underarms, though palms and other sites can be treated — temporarily switching off the local sweat response without affecting the body's overall ability to regulate temperature. For many people whose hyperhidrosis is not adequately controlled by strong antiperspirants, this offers a meaningful reduction in sweating and the associated impact on clothing and confidence. At Jurenko Clinic the physician confirms the area to be treated and may use a simple test to map the sweatiest zones before injecting. The procedure takes around twenty to thirty minutes; the injections are very superficial and a numbing cream can be applied for comfort, particularly for sensitive areas. There is essentially no downtime, and you can return to normal activities the same day. The effect builds over a few days to two weeks and commonly lasts around four to six months, sometimes longer, before it can be repeated. The treatment is intended for adults; suitability is assessed at consultation, and it is not performed during pregnancy or breastfeeding. Where sweating might have an underlying medical cause, the physician will advise on appropriate further assessment.
