Botox for hyperhidrosis, or excessive sweating

Written by: Dra. Montserrat Salvador López

Excessive axillary sweating also called hyperhidrosis is a very frequent problem in the population and affects both men and women that is accentuated in summer with high temperatures and humidity. For those who suffer, hyperhidrosis can become a "nightmare" at the social level due to the spots that appear in the underarm area in shirts and shirts.

The cause of hyperhidrosis is unknown but it is known to be due to an excessive action of the sympathetic nervous system, with anxiety being a triggering factor. Sometimes, this excessive sweating can also affect palms of the hands and soles of the feet.

Botox is an ideal treatment alternative because it has an effectiveness in 100% of cases, and has no adverse or undesirable effects. The duration of its effect is six months, so when summer approaches it can be a very effective solution.

Botox works by pricking at the local level, ie in the armpit, palms or soles, at the intralesional level and blocks the response of the sweat glands and the production of sweat in a completely satisfactory way for the patient. To perform the treatment local anesthetic cream is placed in the area to be treated and injected into the skin superficially with a very fine needle of 30G botulinum toxin type A (100 U of botox), 50 units per side, on an outpatient basis and in a single session. It should be noted that botox is not painful and is tolerated very well.


The effect of botox will be established progressively, being complete 15 days after application, and its duration can range between 4 months and 1 year depending on the metabolism of each patient. To carry out the treatment only 30 minutes are needed in the consultation and it must be repeated every year. In any case it solves the problem completely in summer.


Excessive sweating on palms

In the case of hyperhidrosis affecting the palms of the hands, the causes and treatment are the same as in axillary sweating, but to apply botox it is necessary to use local anesthesia since the palm of the hand is more sensitive than the axilla and therefore its most painful application. Currently, it is not necessary to "suffer", we have local anesthetics that minimize the discomfort in its application.


Frequent questions

Should I have any precaution after applying botox?

It is recommended not to do intense physical exercise or go to saunas or hot baths two hours after treatment.

Does the application of botulinum toxin have side effects?

Botox itself does not cause adverse effects, but pain may be felt at injection sites.

How long is the effect?

The average duration of hyperhidrosis or axillary hypersudation is from 7 months to 1 year, depending on the metabolism of each patient.

By way of conclusion we can say that if you suffer a problem of hyperhidrosis or hyper-sweating in the palms of the hands and / or feet, you should try this treatment. I'm sure you'll find it very satisfying.
