Palmar Hyperhidrosis

Palmar hyperhidrosis is a medical condition where the patient experiences excessive sweating of the palms of the hands.

This condition can lead to damp, sweaty palms, which can be socially embarrassing and may interfere with activities that require a firm grip, such as writing or shaking hands.

What Causes Palmar Hyperhidrosis?

The excessive sweating experienced by patients with palmar hyperhidrosis is related to the overactivity of the sympathetic nervous system, which controls the body’s involuntary responses, including sweating.

It is important to consult a healthcare professional or dermatologist to determine the underlying cause and explore appropriate treatment options tailored to your specific needs.

How to Treat Palmar Hyperhidrosis?

This condition can be treated using various methods, depending on the severity of the condition and the patient’s preferences. The following are some common treatment options:

Topical Antiperspirants

Antiperspirants containing aluminum chloride can be applied to the palms to temporarily block sweat glands’ activity and reduce sweating.


This non-invasive treatment involves immersing the hands in a shallow tray of water while a low electrical current is passed through the water. The electric current helps to block sweat production in the treated area.

Botox® Injections

Botulinum toxin (Botox®) injections can be administered into the palms to temporarily block nerve signals that stimulate the sweat glands, resulting in reduced sweating for several months.

For this procedure, you will be asked to avoid using creams or lotions on your hands. Your hands will be thoroughly cleaned and dried before the application of Botox®. You may also be provided with a topical anesthetic cream or ice pack to numb the palms if the patient is particularly sensitive to needle punctures.

Using a fine needle, your healthcare provider will administer the Botox® to your palms. The injections are strategically placed at multiple sites across the palm to target the sweat glands and block the nerve signals.

Once the injections are completed, you will be able to resume your normal activities. You may be advised to avoid vigorous hand movements or excessive heat exposure for a few hours after the procedure to allow the Botox to settle.

Research shows that this method is 80-90% effective to treat this medical condition.

Which is the Best Option?

The treatment approach will vary based on your preferences, the extent of the condition, and the potential advantages of each option. Consulting with your dermatologist or healthcare provider is important to determine the most appropriate treatment for your case.
