Botox for Sweating - How Long Do the Effects Last?

Botox is used for excessive sweating for focal hyperhidrosis of the axilla, groin, forehead, and inguinal crease. Botox works to inhibit the release of acetylcholine at the nerve synapse.

The longevity of botox depends on the regenerative capacity of the nerve synapse. In most cases, Botox will last about 4 to 6 months for hyperhidrosis.

There are many effective ways to limit the pain associated with Botox injections to the axilla. Discuss these with your surgeon. Hyperhidrosis may also benefit by non-Botox treatments, including thoracic sympathectomy.

If you plan to use BOTOX® as a regular therapy for excessive
sweating, you can expect to return for about two to three visits a year,
depending on how you respond to the treatment. Results can last anywhere from three
to six months depending on a number of variables that are hard to account for.
You should look for a facility with certified staff and the oversight of an MD,
and they’ll be able to walk you through the process, answering whatever
questions or concerns you may have about the treatment.

Typically when botox is used to treat sweating, the effect will last approximately 4 months. Some patients get more and some get less. Botox is very useful at reducing underarm sweating. It is less predictable when treating sweaty palms or soles.- Dr. Bryson Richards

Botox is a great option and highly effective helping excessive sweating, the results last 3-6 months 

Botox typically lasts between 3-6 months for excessive sweating.  This treatment is easily tolerated and quite safe with an experienced injector.

Effective treatment for underarm sweating can be life-changing, so it would be great if there were treatments that could eliminate or greatly reduce the problem without the need for ongoing treatment.

Currently the SmartLipo Triplex or SmartLipo Side-Laze are available to do this.  They are not of any use for sweating in other areas, but this minimally invasive laser treatment is highly effective for the underarms. 

This is an office procedure done under local anesthetic, takes about an hour. The laser is temperature controlled by the Thermal Guide which is a thermistor at the tip of the laser cannula which measures the instantaneous skin temperature. The computer prevents the laser from exceeding a safe temperature which is also programmed into the device.

The laser is moved under the skin in a systematic fashion, resulting in destruction of the sweat glands.
