Sweaty Palms Treatment in Singapore: Your Options, Step by Step
Excessive sweating of the hands (palmar hyperhidrosis) can usually be controlled. Treatment normally starts with a prescription-strength antiperspirant and moves on to iontophoresis, injections or tablets if needed. Surgery (endoscopic thoracic sympathectomy, ETS) is reserved for severe sweaty palms that other treatments have not controlled.
How are sweaty palms treated?
Sweaty palms are usually caused by primary hyperhidrosis: the nerves that control sweating are overactive, so the hands sweat far more than the body needs to stay cool. It is not caused by poor hygiene or weak willpower. First, your doctor will check that the sweating is not caused by another condition; read more about excessive sweating (hyperhidrosis).
Treatment is then stepped up until the sweating is controlled well enough for you.
Sweaty palms treatment options
1. Prescription antiperspirant
Stronger than shop-bought products, usually containing aluminium chloride. Applied to dry hands at night and washed off in the morning. It can sting or irritate the skin, and works better for armpits than palms for many people.
2. Iontophoresis
The hands rest in shallow trays of tap water while a mild electrical current passes through. Sessions of about 20 to 30 minutes are needed several times a week at first, then less often to maintain the effect. Home devices are available.
3. Botulinum toxin injections
Small injections into the palms block the nerve signals to the sweat glands. The effect usually lasts several months, so treatment is repeated. The injections can be uncomfortable, and grip can feel weaker for a short time.
4. Tablets
Anticholinergic medicines, such as glycopyrronium or oxybutynin, reduce sweating all over the body. Side effects such as dry mouth, blurred vision and constipation limit their use for some people.
5. ETS surgery
Keyhole surgery that interrupts the nerves that switch on hand sweating. It has a long-lasting effect but often causes more sweating elsewhere. Read about sweaty palms surgery.
Everyday measures
Avoiding triggers such as heat, caffeine, spicy food and stress can help a little, and a cloth or powder helps grip. These do not treat the cause. Read whether foods or caffeine trigger sweating.
Which treatment is right for me?
The right treatment depends on how severe your sweating is, which parts of the body sweat, how much time you can give to treatment, and your own preferences. Doctors often use the Hyperhidrosis Disease Severity Scale to measure how much sweating affects your daily life.
Mild sweating (scores 1 to 2) often responds to antiperspirants. Moderate to severe sweating (scores 3 to 4) may need iontophoresis, injections or tablets, and surgery is considered only for severe sweaty palms when these have not worked.
| Score | How you would describe your sweating |
|---|---|
| 1 | Never noticeable and never interferes with my daily activities |
| 2 | Tolerable, but sometimes interferes with my daily activities |
| 3 | Barely tolerable and frequently interferes with my daily activities |
| 4 | Intolerable and always interferes with my daily activities |
Hyperhidrosis Disease Severity Scale (HDSS).
When is surgery considered for sweaty palms?
Endoscopic thoracic sympathectomy (ETS) is keyhole surgery under general anaesthesia. Through one or two small cuts under each armpit, the surgeon interrupts the nerve chain that switches on sweating in the hands. Most people notice dry hands straight after surgery.
The main drawback is compensatory sweating: most people sweat more on the back, chest, abdomen or thighs afterwards. For most it is mild, but for some it is bothersome, and it cannot reliably be reversed. That is why ETS is only for severe sweaty palms, after careful discussion.
Dr Kan Yuk Man performs ETS and will go through the benefits and risks with you. Read the full guide to ETS surgery.
- Suits: severe sweaty palms that other treatments have not controlled
- Less suitable: sweating mainly of the feet, armpits or whole body
- Recovery: many people return to light activities within a few days
- Key risk: compensatory sweating elsewhere on the body
Sweaty palms treatment cost in Singapore
The Ministry of Health fee benchmarks for the surgeon’s fee for sympathectomy in private hospitals, including GST:
Anaesthetist and hospital charges for surgery are separate. MediSave and Integrated Shield Plans can be used for surgery where applicable, and Dr Kan is on several Shield plan specialist panels.

Frequently asked questions
Common questions about treating sweaty palms.
Can sweaty palms be cured permanently?
Endoscopic thoracic sympathectomy (ETS) surgery has a long-lasting effect for most people, but it often causes more sweating elsewhere on the body, so it is kept for severe cases. Other treatments control sweating while you keep using them.
Do sweaty palms go away with age?
For some people the sweating eases over the years, but for many it continues into adulthood. If it affects your daily life, there is no need to wait: effective treatments are available.
Are botulinum toxin injections for sweaty palms painful?
The palms are sensitive, so the injections can be uncomfortable. Numbing cream, ice or a nerve block is often used to make them more comfortable. The effect usually lasts several months before a repeat treatment is needed.
Can I do iontophoresis at home?
Yes. After learning how to use it, many people use a home iontophoresis device. Your doctor will check that it is suitable for you first; it is not used in pregnancy or by people with a pacemaker or certain metal implants.
Is sweaty palms treatment covered by MediSave or insurance?
Surgery (ETS) can be partially covered by MediSave and Integrated Shield Plans, subject to policy terms. For non-surgical treatments, check with your insurer.
When should I see a doctor about sweaty hands?
See a doctor if sweating affects your work, studies or social life, or if over-the-counter antiperspirants have not helped. See a doctor promptly if you sweat all over, sweat heavily at night, or the sweating started suddenly in adulthood, as these can point to another medical cause.
