Excessive sweating (Hyperhidrosis)


Injections into the skin in areas affected by hyperhidrosis reduce sweating in these areas by blocking the signals from the brain to the sweat glands.

Around 15-20 injections are given in the affected areas of the body, such as the armpits, hands, feet or face. The procedure usually takes about 30-45 minutes in total.

The effect of the injections usually lasts for several months, after which time the treatment can be repeated if necessary.

Availability of botulinum toxin on the NHS can vary widely depending on your local NHS trust, this treatment is becoming increasingly difficult to obtain this treatment on NHS as it is deemed not clinically urgent.

Botulinum toxin is only licensed for underarm sweating and not for large areas. The skin can be numbed with an anaesthetic cream or injection, but this is often not needed as underarm skin is not very sensitive.
