Botox treatment of hyperhidrosis

Excessive sweating is caused by abnormally functioning sweat glands. Hyperhidrosis can be socially and professionally devastating. It usually effects a single part of the body such as the palms of the hands, armpits, soles of the feet, the lumbar region, groin area or the nape of neck. Botox can help people who suffer from excessive sweating.

What is the cause of excessive sweating (hyperhidrosis)?

Excessive sweating in certain parts of body (focal hyperhydrosis) usually doesn't have a known cause. There are several contributing factors such as a poor diet, anxiety problems, depression, etc.

Most people are familiar with botulotoxin treatment because is can be also used to minimize facial wrinkles.

The procedure to reduce excessive sweating

To reduce excessive sweating, type A botulotoxin (trade names are Botox and Dysport) is injected into the affected area with a very thin needle. A very diluted solution is used for the treatment and only a small amount of the solution is used; approximately one injection per one square cm. of affected area.

Botox works to stop hyperhidrosis because it prevents nerve fiber impulses from effecting the sweat glands.

Before the treatment

During the first consultation, discuss your expectations for the botox treatment openly with your doctor.

The doctor will probably ask you about your general state of health. He/she will also decide where the botulotoxin will be applied by using a special measuring instrument.


The treatment is not severe and does not require anesthesia. Past patients have reported it is less painful than having blood drawn. Anesthetic ointment can be used in case the client is extremely sensitive to pain.

After the treatment

Reduction of excessive sweating  by using botox is an outpatient procedure; you can go home after the treatment.

If the treatment was done on your head, you should not bend the top half of your body forward or lie down for 4 hours. You should not touch the treated places for at least 24 hours. After that, you can touch the area gently and wash it delicately.

What is the result of reduction of excessive sweating with the help of botulotoxin?

The effect of botulotoxin starts to appear gradually anytime from two to 10 days following the treatment. Using botox almost stops the function of sweat glands. The result is always individual, but it typically lasts 7-12 months or longer. Since the results are temporary, often a repeat treatment will be needed.

What is Botox®?

Botulinum toxin is a natural, purified protein with the ability to temporarily block the secretion of the chemical in the nervous system that is responsible for "turning on" the body's sweat glands. By blocking, or interrupting, this chemical messenger, botulinum toxin "turns off" sweating at the area where it has been injected.

Using local injections of botulinum toxin to alleviate the symptoms of hyperhidrosis is a promising new approach. Research has shown that treating the armpits, hands, feet, and face with botulinum toxin is safe and effective. In one clinical study involving 322 patients with severe underarm sweating, 81% of the patients receiving botulinum toxin injections achieved a greater than 50% reduction in sweating. And, 50% of the patients had their excessive sweating relieved for at least 201 days (nearly 7 months).

The treatment

During the procedure, a very fine needle is used to inject small amounts of botulinum toxin just under the skin near the sweat glands responsible for excessive perspiration. Multiple injections are given based on your doctor's assessment of the area that needs to be treated. Injections into the palms or soles may be painful. To ease discomfort, physicians may use one or more of a number of anesthetic techniques such as pain-killing creams or ice.


The results of the treatment appear after three to six days. There is a possibility that during the procedures some sweat glands may be missed. As a result some sweating may appear in the untreated areas. If so it's important to talk to the doctor so that he or she can reevaluate the sweating areas and perhaps "fill in" the gaps with additional injections. Botulinum toxin injections do not cure hyperhidrosis; the symptoms will return gradually. Follow-up injections are required to maintain dryness. These repeat injections may be necessary at intervals varying from eight to twelve months and longer.
