In short

What is the treatment for excessive sweating?

Excessive sweating, or hyperhidrosis, is a medical condition. First-line treatment is usually a strong antiperspirant containing aluminium chloride. Where that fails, options include botulinum toxin injections, prescription medication and referral. Start with your GP rather than a cosmetic clinic.

Duration of toxin effectCommonly four to six months, sometimes longer
ClassificationBotulinum toxin is a prescription-only medicine

How much does hyperhidrosis treatment cost in London?

The cost of hyperhidrosis treatment in London depends on which step of the pathway you are at. Antiperspirant containing aluminium chloride is inexpensive and comes first. Where botulinum toxin is appropriate, price reflects the area, the dose, the prescriber's involvement and whether review is included.

If you have been through the pathway and are considering private treatment, the questions are slightly different from those for a cosmetic procedure:

  1. Has a secondary cause been excluded, and by whom?
  2. Have you completed a proper trial of first-line treatment, applied correctly?
  3. Is the practitioner a prescriber, and are they assessing you in person?
  4. Do they map the area, and how?
  5. What is their experience with this indication rather than with cosmetic treatment?
  6. What happens if the effect is patchy, and is a top-up included?
  7. Are they registered with the Care Quality Commission where the service they provide is a regulated activity?

That last point is worth understanding. In England the Care Quality Commission registers providers of regulated activities. Purely cosmetic injectable treatment usually falls outside that, but treating a medical condition may not. It is a reasonable question to ask.

How long does hyperhidrosis treatment last?

Botulinum toxin for excessive underarm sweating commonly lasts four to six months and sometimes longer, after which the treatment is repeated. Antiperspirant containing aluminium chloride works only while it is being applied as directed. Neither approach cures hyperhidrosis; both manage it for as long as they are continued.

Botulinum toxin blocks the nerve signal that triggers sweat glands, in the same way it blocks the signal to muscle. Injected into the affected skin it reduces sweating in that area for several months. It is a well-established option for underarm sweating where first-line treatment has failed.

Practical points:

  • The area is mapped first, sometimes with a starch and iodine test that shows exactly where the sweating occurs.
  • Many small injections are given across the area. The underarm is generally well tolerated.
  • Onset is over several days to two weeks.
  • The effect commonly lasts four to six months and sometimes longer, generally longer than for cosmetic muscle treatment.
  • Treatment of the palms is more painful and requires nerve blocks, and carries a risk of temporary hand weakness. It is a more specialised undertaking.
  • It is a prescription-only medicine and must be prescribed for you individually after a face-to-face assessment.

Is hyperhidrosis treatment safe?

Hyperhidrosis treatment with botulinum toxin is well established for the underarm and is generally well tolerated. Expect discomfort during the many small injections and possible bruising. Compensatory sweating elsewhere is reported. Botulinum toxin is a prescription-only medicine, so a prescriber must assess you in person first.

  • Bruising and tenderness at the injection sites.
  • Compensatory sweating elsewhere, which some people report.
  • Patchy effect where mapping was imprecise, usually correctable.
  • Temporary weakness of the small muscles of the hand where palms are treated.
  • The usual precautions for botulinum toxin, including pregnancy, breastfeeding and neuromuscular conditions.

Aftercare is straightforward. Avoid strenuous exercise, saunas and steam for around twenty four hours, and avoid applying antiperspirant to the treated area for the first day.

What to expect during and after hyperhidrosis treatment

Expect your GP to be involved first, to exclude a secondary cause and to start the standard pathway. Where botulinum toxin follows, the area is mapped, numbed and treated with many small injections. Sweating usually reduces within a week and the effect is assessed at two weeks.

The standard pathway

  1. Assessment, including which sites are affected, when it started, whether it happens during sleep, and a review of medicines and general health.
  2. Antiperspirant containing aluminium chloride, applied to dry skin at night as directed. This is more effective than most people expect when it is used correctly, and most people use it incorrectly.
  3. Practical measures: fabric choice, absorbent underarm shields, avoiding known triggers.
  4. Where first-line treatment fails, referral or further options including botulinum toxin, oral medication that reduces sweating, or iontophoresis for hands and feet.
  5. Specialist referral for severe cases, where further options including surgery may be discussed.
Using aluminium chloride properly

It is applied to completely dry skin, at night, when sweat glands are less active, and washed off in the morning. Applying it in the morning to damp skin is the usual reason people conclude it does not work. Irritation is common and there are ways to manage it. Ask your GP or pharmacist rather than abandoning it.

Living with it while you work through the options

Practical measures make a genuine difference and are frequently overlooked in favour of procedures.

  • Natural fibres and looser cuts; some technical fabrics manage moisture better than cotton.
  • Absorbent underarm shields, which are inexpensive and effective.
  • Identifying triggers, which for many people include caffeine, alcohol, spicy food and anxiety.
  • Treating anxiety where it is part of the cycle, because sweating and anxiety reinforce each other.
  • Support organisations, which exist for this condition and are worth finding.

None of this is a substitute for treatment where the condition is severe. It is what makes the interval between appointments tolerable.

How to choose a practitioner for hyperhidrosis treatment in London

Choosing where to have hyperhidrosis treatment in London should begin with the NHS pathway rather than a private clinic. Ask any private provider whether they have seen your GP's assessment, who prescribes the medicine, what has been excluded as a secondary cause, and whether the treatment is being described as management rather than cure.

  • Whether a secondary cause has been excluded, which is a medical question rather than a cosmetic one.
  • Which healthcare register the practitioner appears on, and who writes the prescription.
  • Whether first-line treatment has genuinely been tried and reviewed.
  • What the plan is if botulinum toxin does not help, since other options exist.
  • Whether the discussion is framed as long-term management, which is what this is.

Who hyperhidrosis treatment is not suitable for

Hyperhidrosis treatment in a cosmetic clinic is not the right starting point for anyone whose sweating began suddenly, occurs at night, is generalised, or accompanies weight loss, fever or palpitations, because those patterns suggest a secondary cause needing medical assessment. Botulinum toxin is also declined in pregnancy, breastfeeding and neuromuscular disease.

Hyperhidrosis is a recognised medical condition with a defined treatment pathway. It is genuinely disabling for some people, affecting work, clothing and social life, and it is taken seriously by clinicians. It is not a cosmetic complaint and it should not be approached as one.

There are two reasons the GP comes first. The first is that excessive sweating can be secondary to another condition, to a medicine, or to a change such as the menopause, and treating the sweating without establishing why would be a mistake. The second is that effective treatment is available through the NHS, and paying privately for the first step of a pathway you could access anyway is not a good use of your money.

A cosmetic clinic that treats sweating without asking why you sweat has skipped the part that mattered.

Your care

Excessive sweating at The London Aesthetic Clinic.

The same order every time, with the decision made at assessment rather than at the point of sale.

  1. Assessment

    A full assessment of the area, your medical history and a discussion of what excessive sweating can and cannot change for you. Where a prescription-only medicine is involved, this happens face to face with the prescriber before anything is dispensed.

  2. The written plan

    Areas, sequence, product, quantity and cost set out in writing, with the risks that need a protocol named rather than glossed over. You take it away before you consent to it.

  3. The appointment

    A first treatment is deliberately conservative, and you are told what to expect before you leave.

  4. Recovery and aftercare

    Written aftercare, the symptoms that mean you telephone rather than wait, and a route to reach a clinician out of hours.

  5. Review and follow up

    The result is judged at review rather than on the day, once any swelling has settled, and adjustment happens there rather than being sold as a second course.

  6. When it is not the right choice

    Where the finding will not respond to this treatment, that is said plainly and an alternative is discussed rather than a compromise.

Common questions

Should I see my GP first?

Yes. Excessive sweating can be secondary to another condition or a medicine, and effective treatment is available on the NHS. Starting privately skips the assessment that matters.

Does aluminium chloride antiperspirant work?

It works better than most people find, because most people apply it wrongly. It goes on completely dry skin at night and is washed off in the morning.

How long does botulinum toxin last for sweating?

Commonly four to six months and sometimes longer, generally longer than for cosmetic muscle treatment.

Does it hurt?

The underarm is generally well tolerated. Treating the palms is considerably more uncomfortable and needs nerve blocks.

Will I sweat more somewhere else?

Some people report compensatory sweating elsewhere. It is worth discussing before treatment.

Is this available on the NHS?

Treatment for hyperhidrosis is available through the NHS, and the pathway begins with your GP. Availability of specific options varies locally.

Is this a cosmetic treatment?

No. Hyperhidrosis is a medical condition, and it should be assessed and treated as one.
