Hyperhidrosis (Excessive Sweating) Treatment in Kuwait
Primary hyperhidrosis is not poor hygiene and it is not simply nerves; it is a disorder of the nerve control of the sweat glands, affecting 1–3% of people and usually starting in childhood or adolescence. It has a clear treatment ladder that begins with the simplest options, not with injections.
What you should know
- Primary hyperhidrosis affects 1–3% of the population and usually begins in childhood or adolescence, striking specific sites such as the armpits, palms and soles; it may persist for life or ease with age.
- Secondary hyperhidrosis, by contrast, can begin at any age and is often linked to an underlying condition or to a medication the patient is taking. Telling the two apart is the first step in clinic, before any treatment is discussed.
- Treatment is a ladder: we start with topical antiperspirants, then iontophoresis, then botulinum toxin injections, then oral medication — with surgery remaining the last option, not the first.
- Effective antiperspirants contain 10–25% aluminium salts, applied to completely dry skin before sleep and washed off in the morning, anywhere from once weekly to daily as required. Irritation is the commonest reason patients abandon them.
- Botulinum toxin injections are effective but they are not a cure: the effect wears off after three to six months and must be repeated. In a randomised controlled trial, 94% of patients had responded at four weeks and 82% were still responding at week 16.
- Injections into the palms and soles are more painful and may cause temporary weakness of the hand or foot muscles, so at these sites they are used off-licence and only after a frank discussion; the approved indication is axillary sweating.
- Endoscopic thoracic sympathectomy is irreversible: compensatory sweating at other sites follows in 50–90% of patients and is severe in 2% of them, with sweating recurring in up to 15% and pneumothorax in up to 10%.
Treatment options
- Aluminium chloride antiperspirant is first line at most sites. It is applied at night to dry skin; if irritation develops, a short course of hydrocortisone cream helps, and shaving is best avoided within 12 hours of application.
- Iontophoresis suits the palms and soles in particular: a session of 20 to 30 minutes, repeated every one to three days until the desired effect is achieved, then once weekly to maintain it.
- Its results in the hands are good: up to 80–85% of patients notice improvement within two to four weeks. But it demands a long-term commitment, and it is not used in pregnancy, epilepsy, with a pacemaker, or with metal implants.
- Botulinum toxin injection is the approved treatment for axillary hyperhidrosis, given intradermally across the hyperhidrotic area once it has been mapped with the iodine-starch test; the dose in the pivotal trial was 50 units per axilla over 10 to 15 injections.
- Oral anticholinergics are an option when topical measures fail or when sweating is generalised: oxybutynin 2.5–7.5 mg daily or propantheline 15–30 mg up to three times daily. Dry mouth is their commonest side effect, and they are avoided in glaucoma and urinary retention.
- Surgery is only raised once everything above has been exhausted, in a limited number of severe cases — usually disabling palmar sweating — and after a full explanation of the chance of compensatory sweating, which can be more troublesome than the original problem.
The plainest thing I tell anyone asking about botulinum toxin for sweating: this is a treatment you manage, not one you are cured by. The injections give real relief for three to six months and then the sweating returns, so anyone starting should plan for repeat treatment from day one. That is not a flaw in it — but it is a good reason to try topical antiperspirant and iontophoresis first, since they are simpler, less invasive, and may be entirely enough.
Practical advice for patients
The practical points from the patient sheet I hand out in clinic.
- Hyperhidrosis is a real, treatable medical condition — not just "nervousness".
- First line is an aluminium-chloride antiperspirant: apply at night to completely dry skin and wash off in the morning; daily at first, then space out as you improve.
- Mild stinging or itching at first is normal — space out applications and moisturize during the day if it happens.
- An antiperspirant is different from a deodorant, and it can be used on underarms, palms and soles.
- Choose breathable cotton fabrics and dark or white colours that hide marks, absorbent insoles, and keep spare clothing.
- Caffeine, spicy food and stress increase sweating episodes.
- Stronger, very effective options exist: iontophoresis (water-current device), Botox injections for underarms (effective 4–6+ months), tablets, and energy devices — discuss them with your doctor.
- Sudden generalized night sweating with weight loss needs a general medical evaluation.
Frequently asked questions
How long do botulinum toxin injections for sweating last?
Usually three to six months, and some patients continue to benefit for longer. In the pivotal trial, 82% of patients were still responding at week 16. After that the sweating gradually returns and the injections must be repeated — which is why I make this clear before the first session, not after it.
Should I try anything before injections?
Yes. Aluminium chloride antiperspirant at 10–25%, applied at night to dry skin, is first line, and iontophoresis works well for the palms, with up to 80–85% of patients improving within two to four weeks. Many people do well on these alone and never need injections.
Is injecting the palm painful, and will it weaken my grip?
Palmar injections are more painful than axillary ones, and yes, temporary weakness of the hand muscles can occur. That is why they are not used as readily in the palms, and we weigh that trade-off frankly before deciding.
When is surgery considered, and what are its risks?
Only after everything above has failed, and only in severe cases. Endoscopic sympathectomy is irreversible, and compensatory sweating elsewhere follows in 50–90% of patients — severe in 2% — with sweating recurring in up to 15%. That is why I treat it as the last option, not the first.
