Hyperhidrosis is sweating that is more than required to maintain normal heat regulation within the body. Most cases of excessive sweating are idiopathic i.e. there is no known cause for it. In some cases, it can be caused by other conditions or medication, e.g. menopause or some antidepressants.

If you have started with a sudden onset of excessive sweating, we would recommend you consulting your GP so any underlying cause can be investigated in the first instance.

There are a few treatments recommended by your GP or pharmacist for the treatment of hyperhidrosis. You may be familiar with a few of them as follows:-

1.       Topical over-the-counter antiperspirants

2.       Aluminium chloride 10%-35% antiperspirant

3.       Anticholinergic medication

4.       Intradermal injections of botulinum toxin A

5.       Surgery

Botulinum toxin A or Anti-Sweating Injections

An effective and proven treatment available for excessive sweating is the administration of botulinum toxin (Botox®) in the problem area, most commonly the underarms. 

The toxin works by blocking the nerves that supply the eccrine glands, which in turn prevents sweating. There are millions of sweat glands in the body so the ability to sweat will not disappear, something that would not be safe or desirable. Only the area that is treated will be affected. 

A full consultation with a healthcare professional is completed to assess the suitability of treatment.
