Axillary Hyperhidrosis (Excessive Sweating)
Botulinum toxin is frequently referred to as Botox® which is a protein that is produced by a bacteria (Clostridium botulinum).
The toxin works by blocking the chemical at the end of the nerves so that it cannot work on the glands or muscles. In the case of the sweat glands it turns then off to reduce sweating.
It is now used widely to treat a wide variety of medical problems including hyperhidrosis.
How is it done?
It requires multiple small injections of the toxin a few centimetres apart in the armpit. Although not licensed, some doctors do use it for treating hyperhidrosis of the hands, feet, parts of the body and even the face. As you can imagine, injections here tend to be more uncomfortable.
It is generally very effective for treating hyperhidrosis but the effects eventually wear off after about three to six months.
