Hyperhidrosis

(excessive underarm sweating)

Botulinum Toxin has become a widely recognised treatment for hyperhidrosis (excessive underarm sweating), gaining the FDA’s stamp of approval in 2004. To treat severe underarm sweating.

  • 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 requires multiple small injections of the toxin a few centimetres apart in the armpit.

  • It can affect the nearby muscles making then weak. Pain at the site of the injections is not uncommon. Sometimes patients experience flu-like symptoms.

  • Mild discomfort can be felt, however a topical anaesthetic is applied to the whole of the area before treatment.

  • The results of Botulinum Toxin for hyperhidrosis tend to last longer the more treatments you have. The results of the initial treatment will probably last for around 6 months. Some patients have reported the effects lasting for only 4 months, whereas others have said they lasted for up to a year.
