Getting Hyperhidrosis Treated on the NHS: What to Expect
If you are in the UK and struggling with excessive sweating, the NHS can do more for you than most people realise — but the pathway is not always obvious, funding for some treatments varies by postcode, and knowing what to ask for makes a real difference.
This guide walks through the whole NHS route: what your GP can prescribe on day one, when you should be referred to dermatology, what hospital clinics actually offer, what the NHS generally will not fund, and when paying privately starts to make sense.
One thing worth saying upfront: hyperhidrosis is a recognised medical condition, not a hygiene problem or something you should be expected to just live with. The NHS treats it, and NICE publishes a Clinical Knowledge Summary that tells GPs exactly how to manage it. You are not wasting anyone's time by booking an appointment.
Step 1: What Your GP Can Do First
Your GP appointment does two jobs: ruling out an underlying cause, and starting first-line treatment.
Ruling out secondary causes
Primary hyperhidrosis usually starts in childhood or adolescence, affects specific areas (palms, soles, underarms, face) symmetrically, and stops during sleep. If your sweating started suddenly in adulthood, happens at night, or affects your whole body, your GP may run blood tests for causes such as thyroid problems, diabetes or infection before treating the sweating itself. Our guide on when to see a doctor about sweating covers the red flags in detail.
Aluminium chloride prescriptions
The standard NHS first-line treatment is aluminium chloride hexahydrate 20% solution — prescribed as Driclor or Anhydrol Forte. It works by physically blocking the sweat ducts and, used correctly (applied to bone-dry skin at night, washed off in the morning), it is genuinely effective for underarms, hands and feet.
Two practical notes:
- You can buy it without a prescription. Pharmacies sell Driclor over the counter for around £7 to £15, and some GP practices operating self-care prescribing policies will direct you there rather than issue a script. Either way you end up with the same product.
- Skin irritation is the main reason people give up. Reducing frequency, applying to completely dry skin, and using a mild hydrocortisone cream if needed (ask your pharmacist or GP) keeps most people on treatment.
If you want the full technique and product comparison, see our guide to clinical-strength antiperspirants.
Oral medications
If topical treatment is not enough — or your sweating is generalised — GPs can prescribe anticholinergic tablets that reduce sweating body-wide. Propantheline bromide is the only oral medicine licensed for hyperhidrosis in the UK; oxybutynin and glycopyrronium are prescribed off-label, which the NICE CKS explicitly supports as an option. Dry mouth and other anticholinergic side effects are common and dose-dependent, so this is a discussion to have with your GP rather than something to self-direct. Our prescription medications guide explains how each drug works and what the trade-offs are.
Step 2: Referral to NHS Dermatology
NICE CKS advises GPs to consider a dermatology referral when:
- First-line treatments (aluminium chloride plus lifestyle measures, with or without oral medication) have been tried and have not worked well enough
- Sweating is having a significant impact on your quality of life — work, relationships, mental health
- The diagnosis is uncertain or a secondary cause needs specialist investigation
That first point matters practically: turning up to your GP having already tried a clinical-strength antiperspirant properly for several weeks shortens the path to referral. Keep a simple record of what you used, for how long, and what happened.
Referrals for hyperhidrosis are almost always triaged as routine, so expect a wait — the NHS 18-week referral-to-treatment standard applies, but many dermatology departments currently run longer for non-urgent conditions. Under NHS patient choice you can ask to be referred to any provider that holds an NHS contract, and waiting times differ a lot between hospitals, so it is worth asking your GP surgery to check options on the e-Referral Service.
What NHS Dermatology Actually Offers
Iontophoresis
For sweaty hands and feet, iontophoresis — passing a mild electrical current through water-soaked skin — is the workhorse NHS treatment. Some dermatology departments run iontophoresis clinics where you attend for an initial course (typically two to three sessions a week for a few weeks), then taper to maintenance.
The catch is access. Not every trust runs a clinic, sessions require repeat hospital visits, and maintenance is lifelong. Many people start on the NHS to confirm it works for them, then buy a home machine — devices like Dermadry cost roughly £300 to £400 and pay for themselves quickly compared with travel and time off work. Our home iontophoresis guide covers machine choice and technique. (Some product links on this site are affiliate links — see our disclaimer.)
Botox for underarm sweating
Botulinum toxin injections are one of the most effective treatments available for severe axillary hyperhidrosis, typically reducing underarm sweating by over 80% for four to nine months per treatment round.
On the NHS, the honest picture is:
- Botox for underarm hyperhidrosis is an established hospital dermatology treatment, and some areas commission it routinely for people who have failed topical treatment.
- Funding varies by Integrated Care Board (ICB). Some ICBs class it as a "procedure of limited clinical value" and require an Individual Funding Request (IFR) demonstrating exceptional circumstances; a few effectively do not fund it. Your dermatologist will know the local policy and can submit the IFR paperwork.
- Because the effect wears off, you need repeat treatment — and repeat funding — roughly every six months, which is part of why commissioning is patchy.
- Botox for palms, soles or face is rarely offered on the NHS: it is more painful, more fiddly, and (for hands) carries a temporary risk of grip weakness.
Specialist prescribing
Dermatologists can also optimise oral medication — for example titrating oxybutynin or glycopyrronium doses beyond what a GP may be comfortable initiating — and combine treatments (antiperspirant plus iontophoresis plus low-dose oral medication is a common real-world stack).
What the NHS Generally Does NOT Fund
Setting expectations here saves you a frustrating appointment:
- miraDry — microwave destruction of underarm sweat glands is private-only in the UK. No NHS commissioning.
- ETS surgery — endoscopic thoracic sympathectomy is technically available and covered by NICE guidance (IPG487), but it is treated as an absolute last resort because compensatory sweating elsewhere on the body affects a large proportion of patients and is sometimes worse than the original problem. NHS referrals for ETS are rare and only follow failure of everything else. Read our ETS surgery guide before you even consider this route.
- Glycopyrronium wipes (Qbrexza) — not licensed or routinely available in the UK.
- Repeat private-style cosmetic requests — Botox for mild sweating, or for cosmetic preference rather than documented quality-of-life impact, will not pass IFR panels.
NHS vs Private: Cost Comparison
NHS treatment is free at the point of use (prescription charges aside — £9.90 per item in England as of 2025/26, free in Scotland, Wales and Northern Ireland). Private treatment costs real money but skips the queue and unlocks treatments the NHS will not fund.
| Treatment | NHS | Private (typical UK price) | |---|---|---| | GP appointment + aluminium chloride (Driclor) | Free (or ~£7–£15 OTC) | £50–£100 private GP consult | | Oral medication (oxybutynin, glycopyrronium) | Free apart from prescription charge | £150–£250 initial derm consult + private prescription | | Iontophoresis (clinic course) | Free where commissioned; waiting list | £40–£70 per session privately | | Iontophoresis (home machine) | Not usually provided | £300–£400 one-off purchase | | Botox — underarms | Free where ICB funds it; repeat funding needed | £350–£600 per session, every 4–9 months | | Botox — hands/feet | Rarely available | £400–£700 per session | | miraDry | Not funded | £1,500–£2,500 per session (often 2 sessions) | | ETS surgery | Rare, last resort only | £3,500–£6,000+ |
When Private Treatment Makes Sense
Going private is not an all-or-nothing decision — most people mix the two. It tends to make sense when:
- You want underarm Botox and your ICB will not fund it (or the IFR was refused). At £350–£600 twice a year, many people decide the impact on their working life justifies it.
- The dermatology waiting list is very long and a single private consultation (£150–£250) gets you a diagnosis, a treatment plan and a private prescription months sooner. You can often transfer back to NHS care afterwards.
- You want miraDry, since there is no NHS route at all.
- Home iontophoresis beats clinic iontophoresis for you — strictly speaking this is self-pay rather than "private healthcare", and it is the single most cost-effective upgrade for hands and feet.
What private treatment does not do is unlock secret options: the underlying treatments are the same ones described in the NICE CKS. You are paying for speed and availability, not different medicine.
Making the Most of the NHS Route
A realistic, GP-friendly plan looks like this:
- Try a proper aluminium chloride routine for four to six weeks (buy Driclor from a pharmacy today — no appointment needed).
- Book a GP appointment, describe the quality-of-life impact honestly, and mention what you have already tried.
- Discuss oral medication if topicals are not enough.
- Ask directly about referral criteria and your local ICB's Botox commissioning position if underarm sweating is the main problem.
- If you are referred, use patient choice to pick the shortest waiting list.
