What treatments are there for excessive sweating?

Approximately 3% of people worldwide experience hyperhidrosis (excessive sweating). From a health perspective, it doesn't usually require medical intervention, but some people may seek treatment because it can be uncomfortable and embarrassing.

Treatment options for hyperhidrosis range from medical antiperspirants and oral medications to more complex ones like iontophoresis, botox, and sympathectomy.

You can also manage hyperhidrosis by making a few lifestyle changes, like wearing loose clothing and changing your diet.

Medications for hyperhidrosis

Treatment for hyperhidrosis can include topical solutions and oral medications. The one you choose depends on your medical history and personal preferences.

Product Form Active ingredient How it works Time to work Dosage Possible side effects
Driclor solution 20% Roll-on Aluminium chloride hexahydrate Builds a barrier across your sweat glands Within a week or two Daily Stinging Redness Burning sensation Itching Irritation
Glycopyrronium bromide - 2mg Oral tablet Glycopyrronium bromide Blocks the chemical that produces sweat Varies from hours to days Once daily Dry mouth Constipation Diarrhoea Vomiting Nasal congestion Urinary problem Agitation
Oxybutynin - 2.5mg and 5mg Oral tablet Oxybutynin hydrochloride Blocks the chemicals that trigger the production of sweat Four to six weeks Once daily Dry mouth Abnormal heartbeat Blurred vision Digestion issues Dry skin

Antiperspirant

Medical antiperspirants, such as Driclor and Anhydrol Forte, are roll-on treatments containing aluminium chloride. It stops sweating by forming a plug on your sweat ducts, which blocks sweat from being released.

It’s typically applied once a day directly onto clean skin. You can apply it on any part of your skin, including your underarm, hands and feet.

While deodorants containing aluminium are available in general stores, these often contain a lower percentage and may not be as effective as medical antiperspirants.

Medicines

Oral medications like Oxybutynin and Glycopyrronium bromide are off-label treatments used to treat excessive sweating. They work by blocking a chemical in the body called acetylcholine. This chemical is responsible for sending signals to the sweat glands. When acetylcholine is blocked, the sweat glands don’t receive the signals that tell them to produce sweat.

Oxybutynine is an effective treatment for hyperhidrosis, with patients reporting over 70% improvement in their symptoms. Likewise, similar results were shown with Glycopyrronium bromide, but a third of patients did experience side effects, which affected treatment efficacy.

Lifestyle changes and home remedies to help with hyperhidrosis

Hyperhidrosis can happen at seemingly random times and without any obvious cause. This can put you in unexpected situations where you experience excessive sweating.

While you can’t prepare for every hyperhidrosis episode, certain lifestyle changes may help reduce sweating or make it less noticeable.

Clothing and hygiene tips

Choose loose, breathable clothing made from materials like linen or cotton. Some polyester blends can make you more sweaty and smelly, while natural fibres promote air circulation.

If you need to wear tight clothing, try using sweat pads. These pads are stuck directly to your clothes, helping catch sweat and prevent sweat stains.

Additionally, keep the areas prone to sweat clean and dry. Wash them regularly with a mild soap to reduce bacterial growth. This will stop the sweat from smelling.

Stress reduction techniques

Anxiety and stress are common triggers for sweating. Adding relaxation methods like yoga, meditation, or deep breathing exercises to your daily routine can calm your nerves, reducing the risk of sweating excessively. These activities enhance general wellness and can effectively alleviate stress related to sweating.Yoga icon

Dietary considerations

Although there's no specific hyperhidrosis diet, certain foods can trigger sweat or reduce it.

Foods high in water content, like watermelon, cucumber, tomatoes, and oranges, can regulate your internal temperature, which may help reduce sweating. Similarly, calcium-rich foods, like milk, cheese and leafy greens, have the same effects and may reduce sweat. 

On the other hand, spicy foods can trick your body into thinking that it's overheating, which can lead to sweating. Alcohol may also increase sweating as it dilates your blood vessels and raises body temperature.

What are non-surgical procedures for hyperhidrosis?

Iontophoresis and Botox are the two main non-surgical procedures for excessive sweating.

Iontophoresis

Iontophoresis is a process that temporarily stops signals from being sent to your sweat gland.

The process involves placing your hands or feet in shallow water, where a weak electric current is passed. This stops the electric signals in your body from being sent to your sweat glands, helping reduce excessive sweating. It’s a relatively painless treatment with many individuals only experiencing tingling.

The procedure can last up to 30 minutes. Initially, you’ll need several sessions every few days, which can be a big time commitment. But after that, you’ll only need a maintenance session every couple of weeks to a couple of months. The results can last up to 14 weeks.

Studies have shown that iontophoresis is an effective treatment for hyperhidrosis. In one study, over 90% of patients reported an improvement in symptoms.

Botox

Botox, or botulinum toxin, is injected into the affected areas. This blocks nerve signals in the sweat gland, temporarily reducing excessive sweating. It can be performed on all areas of your body, including your underarms, hands, and feet.

Within two weeks, you should notice a significant improvement in your symptoms. The results from one session can last up to 6 months , making it more convenient than iontophoresis. However, it can be a painful procedure for some individuals.

Surgical interventions for hyperhidrosis

Sympathectomy

Endoscopic thoracic sympathectomy (ETS) is a keyhole surgery where the nerve tissue that controls the sweat gland is removed, which permanently reduces sweating. This procedure is typically performed on the armpits or hands. 

Many patients report significant improvements with sympathectomy, but it does carry more risks than non-surgical treatment or medications.

Some of the side effects can include;

  • Compensatory sweating is when you sweat in other areas of your body to compensate for the lack of sweat on the treated areas.
  • Horner’s syndrome is when you experience sweating on one side of your face due to nerve damage.
  • Heat strokes are more common if sympathectomy is performed on larger areas of your body.

Managing hyperhidrosis

Hyperhidrosis is a medical condition and should be treated as such. While it doesn’t always require treatment from a medical perspective, if it causes mental or emotional stress, various treatment options are available to help reduce sweating.

It’s up to you which you choose, and if you’re uncertain, a clinician can help.
