The short answer

What excessive sweating treatment is

For some people, sweating can become a persistent issue, affecting their daily lives and self-confidence. Axillary hyperhidrosis is characterised by excessive underarm sweating and commonly affects both men and women. While sweating in response to heat, exercise or stress is normal, individuals with axillary hyperhidrosis experience excessive sweating that is often unrelated to external triggers.

Dr Harriet also has specialist experience in treating other areas of the body for sweating, such as the scalp, face and hands. Her patients have often tried several other treatments before coming to her.

What can be treated?

Treatment is for sweating that happens without the usual triggers. Where an underlying medical cause is driving it, that needs investigating first, and Dr Harriet will assess for this at consultation.

Patient journey

What to expect from sweating treatment

Consultation & preparation

Do not shave the underarms for 24 hours before treatment, and avoid antiperspirant on the day of your appointment. Avoid alcohol for 24 hours and ibuprofen, aspirin, vitamin E and fish oil for 48 hours beforehand where it is safe to stop them.

During treatment

How does the treatment work?

Sweat glands are switched on by a nerve signal. The injected protein temporarily blocks that signal at the treated site, so the glands in that area produce far less sweat. Nothing is removed and no gland is destroyed, which is why the effect wears off over months and the treatment is repeated rather than permanent.

How effective is it, and how fast?

Treatment with botulinum toxin is extremely effective in the underarms, reducing sweating by around 70 to 95 per cent. The results start to kick in after around 48 hours, with the full effect after one week. Most patients have treatment every six months, during which time the effects gradually wear off. There is no evidence that this treatment causes ‘rebound sweating’, in which other areas of the body start to sweat more to compensate.

What if I have already tried other treatments?

Most patients have. Dr Harriet’s patients have often tried several other treatments before trying botulinum toxin for excessive underarm sweating, such as iontophoresis (electric current therapy), oral medications, prescription-strength antiperspirants containing aluminium chloride (such as Driclor) or even surgery (thoracic sympathectomy). These treatments are often found to be ineffective or to have significant side effects. This treatment offers patients a safe and effective way to reduce sweating.

Why does the anxiety connection matter?

Anxiety and axillary hyperhidrosis often go hand in hand. Excessive underarm sweating can be a source of significant distress, leading to anxiety and reduced self-confidence. This anxiety can create a vicious cycle, as stress and emotional tension further exacerbate sweating. Patients experiencing excessive underarm sweating may avoid social situations, public speaking, or even handshakes, fearing embarrassment. Breaking that cycle at the sweating end is often what allows the anxiety around it to settle.

Aftercare

Avoid antiperspirant, strenuous exercise, saunas, steam rooms and alcohol for 24 hours. Sweating begins to reduce after around 48 hours, with the full effect at one week. Most patients return for re-treatment at around six months as the effect wears off.

FAQ

Excessive sweating FAQs

How much will the treatment reduce my sweating?

In the underarms, treatment is extremely effective and reduces sweating by around 70 to 95 per cent. It is a reduction rather than complete elimination, which is intentional, since some sweating is normal and necessary. Dr Harriet will discuss realistic expectations for your particular pattern at consultation.

Will I start sweating more somewhere else?

There is no evidence that this treatment causes rebound sweating, in which other areas of the body start to sweat more to compensate. This is a common worry among patients and it is not borne out. Dr Harriet is happy to talk through the evidence with you at your consultation.

How often will I need treatment?

Most patients have treatment every six months, during which time the effects gradually wear off. Some find they can stretch the interval slightly, particularly if their sweating is seasonal. Many patients book ahead for spring so they are covered through the summer months.

Can areas other than the underarms be treated?

Yes. Dr Harriet has specialist experience in treating other areas of the body for sweating, such as the scalp, the face and the hands. These areas are assessed and quoted individually at consultation, because both the dose and the injection technique differ from standard underarm treatment and the expected reduction varies by site.
