Understanding Why Your Hands Won't Stop Sweating
If you're searching for how to stop sweaty hands, you already know the frustration. Dropping your phone, avoiding handshakes, leaving damp marks on every surface you touch — palmar hyperhidrosis is common, though reliable UK-specific figures are not available, yet most people suffer in silence for years before seeking treatment.
The good news? There are more effective solutions available today than ever before, ranging from simple home remedies to medical procedures with high success rates. This guide walks through every option, from the mildest to the most advanced, so you can find the approach that works for your life. For a deeper dive into causes, diagnosis, and treatment pathways, see our complete guide to hand sweating.
What Causes Sweaty Hands?
Palmar hyperhidrosis is a form of primary focal hyperhidrosis, meaning the excessive sweating is localized to a specific area (in this case, the palms) and is not caused by another medical condition. The eccrine sweat glands in your hands are overactivated by the sympathetic nervous system, often without any obvious trigger like heat or exercise.
Research published in the Journal of the American Academy of Dermatology suggests a strong genetic component — if one of your parents has hyperhidrosis, there is roughly a 25% chance you will develop it too. The condition typically begins in childhood or adolescence and can persist throughout life without treatment.
When Sweaty Hands Signal Something Else
In some cases, excessively sweaty palms can be a symptom of an underlying condition such as thyroid disorders, diabetes, menopause, or certain medications. If your sweating started suddenly in adulthood or is accompanied by other symptoms, it is important to rule out secondary causes with your doctor.
Home Remedies for Sweaty Hands
Before investing in medical treatments, many people find partial relief through accessible home strategies.
Antiperspirant Lotions and Creams
Over-the-counter antiperspirant lotions designed for hands can reduce mild to moderate sweating. Look for products containing aluminium chloride or aluminium chlorohydrate. Apply to clean, dry hands before bed and wash off in the morning. The aluminium salts temporarily block sweat ducts, reducing output over time. Two of the most popular hand options are compared head-to-head in our Carpe vs SweatBlock guide.
For stronger formulations, 20% aluminium chloride hexahydrate is available in UK pharmacies over the counter as Driclor or Anhydrol Forte — no prescription or dermatology referral needed, though they are sold under a pharmacist's supervision.

Sage Tea Soaks
Sage contains tannic acid, a natural astringent. Some people report mild improvement by soaking their hands in brewed sage tea for 20 minutes daily. While clinical evidence is limited, it is a low-risk option worth trying alongside other treatments.
Cornstarch and Baking Soda
A mixture of cornstarch and baking soda applied to the hands can absorb moisture temporarily. This is more of a quick-fix than a treatment, but it can help in situations where you need dry hands for a short period.
Over-the-Counter Products That Help
Beyond basic antiperspirants, several OTC products are specifically formulated for hand sweating:
- Antiperspirant hand lotions — Products like Carpe Antiperspirant Hand Lotion use aluminium sesquichlorohydrate in a non-greasy formula designed for daytime use.
- Grip-enhancing products — Originally designed for athletes, these can help with the functional problems caused by sweaty hands.
- Absorbent hand powders — Talc-free powders can provide temporary relief during the day.
Prescription Medications for Sweaty Hands
When OTC options fall short, several prescription treatments have strong evidence behind them.
Oral Anticholinergics
Medications like glycopyrrolate and oxybutynin work systemically by blocking the neurotransmitter acetylcholine, which signals your sweat glands to activate. Studies show these medications can substantially reduce sweating in many patients. However, side effects such as dry mouth, constipation, and blurred vision are common and can limit their use.
Topical Glycopyrronium
Topical anticholinergic wipes (such as Qbrexza) deliver the medication directly to the skin, potentially reducing systemic side effects. While FDA-approved for underarm sweating, some dermatologists prescribe them off-label for palms.
Iontophoresis: The Gold Standard for Hands
Iontophoresis is widely considered the most effective non-invasive treatment for palmar hyperhidrosis. The process involves placing your hands in shallow trays of water while a medical device passes a mild electrical current through the water. This current is thought to temporarily disrupt the signaling between nerves and sweat glands.
What to Expect
- Initial phase: Daily 20-30 minute sessions for 1-2 weeks
- Maintenance phase: Sessions 1-3 times per week
- Success rate: Studies report good results for many people for palmar hyperhidrosis
- Downside: You need to maintain a regular schedule or sweating returns
Many patients invest in a home iontophoresis device, which eliminates the need for repeated clinic visits. Devices like the Dermadry, Fischer, and RA Fischer are popular choices. Learn more in our complete guide to iontophoresis at home. If your feet sweat as much as your hands, iontophoresis treats both — see our guide to sweaty hands and feet.
Botox Injections for Sweaty Hands
Botulinum toxin (Botox) injections are FDA-approved for axillary hyperhidrosis and used off-label for palms with excellent results. The toxin blocks the release of acetylcholine at the nerve-sweat gland junction, effectively shutting down sweat production in the treated area.
Effectiveness and Considerations
- Success rate: a large reduction in sweating for most people
- Duration: Effects last 3-6 months before retreatment is needed
- Pain factor: Hand injections can be painful due to the density of nerve endings in the palms. Many providers use nerve blocks or ice to manage discomfort.
- Cost: Typically $1,000-$1,500 (about £744–1,116) per session, though insurance may cover it with a hyperhidrosis diagnosis
- Temporary side effect: Some patients experience mild weakness in grip strength for 1-2 weeks
ETS Surgery: A Last Resort
Endoscopic thoracic sympathectomy (ETS) involves surgically cutting or clamping the sympathetic nerves that control hand sweating. It is the most definitive treatment, with success rates above 95% for palmar hyperhidrosis.
However, ETS carries significant risks, most notably compensatory sweating — excessive sweating that develops in other body areas (trunk, back, legs) after surgery. Studies report compensatory sweating in around 60% of patients (pooled estimate 62%, 95% CI 51–72%), and in some cases, it can be worse than the original problem. For this reason, most specialists consider ETS a last resort after all other treatments have failed.
Building Your Treatment Plan
The best approach is to start with the least invasive options and work your way up:
- Start here: OTC antiperspirant lotions and hand powders
- Next step: Prescription-strength topical antiperspirants
- Strong option: Home iontophoresis (high success rate, no systemic side effects)
- Medical treatments: Oral anticholinergics or Botox injections
- Last resort: ETS surgery (only after exhausting all other options)
Many people find success by combining treatments — for example, using iontophoresis as a primary treatment with an antiperspirant lotion for touch-ups during the day.
