Excessive Sweating (Hyperhydrosis)

Excessive sweating (Hyperhidrosis) is a relative common disorder that produces a lot of unhappiness worldwide. One to 3% of the New Zealand population suffer from excessive sweating of the underarms, palms or soles of the feet. Although systemic disorders can sometimes cause excessive sweating, most cases occur in people who are otherwise healthy. High temperatures, physical activities and stress may trigger excessive sweating in some, but majority people will perspire profusely regardless of their circumstances. 

The initial treatment of excessive sweating may include: Over-the-counter antiperspirants; Prescription-strength antiperspirants (e.g. aluminum chloride hexahydrate); Iontophoresis; Oral medications (e.g. anticholinergic drugs, beta blockers, and anxiolytics); Microwave thermolysis, and in severe cases even skin grafts.

BOTOX® (botulinum toxin) is another safe and non-invasive treatment option approved in the New Zealand by Medsafe for treating excessive underarm sweating. BOTOX® is injected in small quantities into the skin to treat the symptoms of severe underarm sweating when other medicines fail to work in people 18 years and older. Recommend patients see a General Practitioner or Dermatology specialist prior to initiating botox injections.

Topical freezing, pressure or local anaesthetic cream is usually applied beforehand to minimize discomfort. Most people do not find the procedure uncomfortable. The treatment usually takes about 30 minutes to perform and people can return to work immediately following the procedure. Usually the BOTOX® starts working within 1 week of injection and brings significant relief to the vast majority of people. BOTOX® injected into the armpit regions will last 6-7 months with some people having lasting results for over a year.
