What treatments help control excessive sweating?

Treatment options available for excessive sweating (hyperhidrosis) depending on the area and cause

Summary in 60 seconds

• Sweating itself is not bad, it helps regulate temperature; however, doing it excessively can become a medical problem.
• Antiperspirants are usually the first treatment for localized sweating.
• Iontophoresis is a particularly useful option for hands and feet.
• Topical medications and botulinum toxin can also be used in the armpits.
• Some procedures act directly on the sweat glands.
• The pills can help, but they require specialized medical evaluation due to their adverse effects.
• Surgery is reserved for selected situations.
• When there is a disease or a responsible drug, addressing that cause is part of the treatment.
• The goal is to reduce the interference of sweat in daily life with a tolerable and safe option.

What is hyperhidrosis?

Hyperhidrosis is excessive sweating beyond what is necessary to regulate body temperature. It can affect specific areas—such as the armpits, palms, soles, or face—or spread over a large part of the body.

It is not defined solely by the amount of sweat. Its impact also matters: soaking through clothing or hindering daily activities may warrant a visit to the doctor. Sweating during exercise or in a hot environment, however, does not in itself mean you have hyperhidrosis. British Association of Dermatologists, 2022 .

Why does hyperhidrosis occur?

In primary hyperhidrosis , there is increased activation of the nerve mechanisms that stimulate the sweat glands, without any other underlying medical condition being identified. It usually begins at a young age and affects specific areas on both sides of the body.

Secondary hyperhidrosis is related to another condition, a medication, or certain physiological changes. It can be localized or generalized. Distinguishing between these two forms is important because treatment involves more than just reducing sweating; it may also be necessary to address the underlying cause. Nawrocki, 2019 .

Stress can intensify sweating, but primary hyperhidrosis should not be attributed simply to “being a nervous person.” Worry about sweating can also be a consequence of the problem. Primary Care Dermatology Society, 2026 .

What treatments help control excessive sweating?

Antiperspirants: a first step that depends on how they are used

• Antiperspirants containing aluminum salts reduce sweat production by acting on the sweat ducts. They are frequently used as a first-line treatment for localized hyperhidrosis.
• Aluminum chloride preparations are usually applied at night and removed in the morning, following the product or professional instructions. Once sufficient control is achieved, the frequency of use can be reduced.
• Its main limitation is irritation: burning, itching, or redness. A more potent formulation is not necessarily the most suitable for sensitive skin. If the product causes irritation, it’s best to adjust the concentration and frequency of application rather than repeatedly increasing the number of applications. McConaghy, 2018 .

Topical medications: prescription alternatives for underarms

• There are medications that can be applied to the skin to reduce the signals that stimulate sweat production. These include certain formulations of glycopyrronium and sofpironium .
• Clinical trials with topical glycopyrronium have shown a reduction in sweating and its perceived intensity in people with primary axillary hyperhidrosis. It is not a deodorant, but a medication with specific indications and precautions. (Glaser, 2019 )
• Sofpironium has also shown benefits in clinical trials for axillary hyperhidrosis. These results correspond to specific formulations: they do not demonstrate that any preparation with the same active ingredient will work equally well, nor that it can be used indiscriminately in other areas without medical evaluation. Pariser, 2025 .
• Applying it to the skin does not mean it is free from systemic effects. For example, sofpironium can cause dry mouth, blurred vision, or difficulty urinating. It is important to avoid contact with the eyes, wash your hands, and follow the application instructions. Availability and indications should be checked for each country and product. Botanix SB Inc., 2025 .

Iontophoresis: especially useful in hands and feet

• Iontophoresis uses a weak electrical current that passes through water in contact with the skin. The hands or feet are usually placed in trays prepared for the treatment.
• It requires an initial phase of repeated sessions and, if effective, maintenance. After receiving training, some people continue to use it at home.
• It can cause tingling, irritation, or minor burns if used incorrectly. Devices should not be improvised, and the intensity should not be increased without medical advice and supervision.
• It is not suitable for people with certain implanted electronic devices, such as a pacemaker. Metallic implants located in the path of the current also always require specialist medical assessment before use. British Association of Dermatologists, 2022 .

Botulinum toxin: localized control for several months

• Botulinum toxin is administered through small injections and temporarily reduces the signals that activate the sweat glands.
• It is used on the underarms and other selected areas. Improvement usually begins during the first or second week and lasts for several months, although the response varies.
• Injections can cause pain and bruising. Temporary muscle weakness may also occur in the hands, which is relevant for those who need precision or manual strength. American Academy of Dermatology, 2024 .

Oral medications: useful in some cases, with more precautions

• Oxybutynin is one of the medications that can be considered when sweating affects several areas or is not sufficiently controlled with other alternatives.
• In a placebo-controlled clinical trial, it improved the severity of hyperhidrosis and the quality of life for some participants. However, not everyone responded, and dry mouth was common. These results support its use in selected patients, not the idea that it is a suitable solution for everyone. Again, a specialist medical evaluation is mandatory before considering its use. Schollhammer, 2015 .
• Oral glycopyrrolate may also be used, depending on the clinical context. These anticholinergic medications can cause constipation, blurred vision, and difficulty urinating, in addition to dry mouth.
• A key precaution is the risk of overheating. By reducing sweating in different parts of the body, they can hinder heat loss, especially during exercise or in hot environments.
• Before prescribing them, other treatments and medical history are always reviewed, such as glaucoma, urinary problems, or certain digestive diseases. Their use for hyperhidrosis is strictly medical. Glaser, 2015 .

Procedures on the glands: mainly for the armpits

• Microwave thermolysis uses energy to destroy part of the underarm sweat glands. It can offer long-lasting reduction and differs from options that require frequent application.
• A comparative trial found improvement with this technique and with botulinum toxin, with differences in aspects such as odor and hair reduction. The results support an individualized choice, not the universal superiority of one procedure. Grove, 2024 .
• Microwaves can cause pain, inflammation, and changes in sensation. Less common risks include burns and nerve damage. Local gland removal procedures can also cause scarring and other complications. American Academy of Dermatology, 2024 .

Surgery: a decision for highly selected cases

• Endoscopic thoracic sympathectomy interrupts certain nerve pathways involved in sweating. It may be considered in severe hyperhidrosis of the upper extremities when other alternatives have not provided adequate control.
• Its main limitation is compensatory sweating : after the operation, sweating may increase in other parts of the body. In some people, this can be intense and more bothersome than the initial problem.
• Therefore, the decision requires a detailed discussion about benefits, alternatives, surgical risks, and potentially long-term consequences. It should not be presented as a simple solution or a complication-free intervention. National Institute for Health and Care Excellence, 2014 .

Everyday measures that complement the treatment

• Breathable clothing, absorbent underarm pads, and changing wet socks can improve comfort. Allowing footwear to dry before wearing it again also helps.
• Recording when sweating occurs allows you to identify personal triggers, such as certain drinks, foods, or situations. Not everyone experiences the same triggers.
• These measures complement treatment; they do not replace medical evaluation and assessment when sweating is persistent or limits normal activities. American Academy of Dermatology, 2025 .

Frequently Asked Questions

What is the best treatment for sweaty hands?

• There is no single option suitable for everyone. Iontophoresis is an alternative, especially useful for hands and feet, but it requires consistency and maintenance sessions. The choice depends on the severity of the problem and each patient’s individual circumstances. British Association of Dermatologists, 2022 .

Is hyperhidrosis curable?

• Many treatments control sweating while they are used or for a limited time. Some interventions have long-lasting effects, but they can also produce persistent consequences. It is important to distinguish between long-lasting control and a promise of a complete and risk-free cure. A clear conversation with your doctor about realistic expectations is always essential. National Institute for Health and Care Excellence, 2014 .

What should I do if the antiperspirant causes a burning sensation?

• Avoid continuing to apply it to irritated skin. It is advisable to review the formulation, frequency, and application technique before continuing. Irritation is an adverse effect, not a sign that the treatment is working better. McConaghy, 2018 .

Can treatments be combined?

• Sometimes different options are used for different areas. However, combinations of medications require medical evaluation: some anticholinergic products should not be administered together due to the risk of increased adverse effects. Botanix SB Inc., 2025 .

Can children and adolescents receive treatment?

• Yes, options exist, but they must be selected according to age and product. For example, certain sofpironium formulations have a specific pediatric indication in the United States; this does not make all sweat medications appropriate for every child. Medical evaluation is essential. Botanix SB Inc., 2025 .

And during pregnancy or breastfeeding?

• Each treatment needs to be reviewed before starting or continuing it. Safety information is not the same for all options. For example, iontophoresis is usually avoided during pregnancy because its potential risks are not sufficiently evaluated. British Association of Dermatologists, 2022 .
