Botox for sweating

Thank you for your question emansur0423. Botox is a purified protein used to address wrinkles associated with facial expression. It can also be used on the underarms, palms, and soles for excessive sweating. This is a very safe treatment. Risks include pain, bleeding, bruising, redness, swelling, and infection. Please consult with a doctor for specific recommendations. Good luck!

Botox is FDA approved for use in preventing excessive sweating in the underarms.

Botox is FDA approved for use in preventing excessive sweating in the underarms, and is safe and effective when administered by an experienced, board-certified dermatologist with experience using Botox as a treatment for hyperhidrosis. You may experience minor discomfort, swelling, or bruising, but these will resolve on their own and can be managed easily.

Botox for excessive underarm perspiration

Botox has an FDA indication for hyperhydrosis. The botox is injected intradermally and not subcutaneously. We map the perspiration pattern on initial consultation with a starch ninhydrin test that we do with Betadine solution and corn starch. We photograph the underarm reaction, for future injections, then generally inject each side with approximately 40 units of Botox Cosmetic. The treatments have been so successful, that over time the intervals get longer and longer between injections. Our typical duration is 9 months to 1 year.

Safety of Botox for Hyperhidrosis (Axillary / arm sweating)

Dear emansur0423:

Botox (and its "cousins" Dysport and Xeomin) performs many functions other than relaxing muscle fibers and thereby decreasing folds and wrinkles of the face.

Botox blocks the release of a chemical called acetylcholine from a nerve ending. If the acetylcholine never arrives to the muscle fiber, the muscle will not contract.

Botox is also FDA indicated through the same blocking mechanism to prohibit the release of sweat in the glands under the arms. Once injected it may take a week or 2 to act and typically reduces sweating for 6 months or longer. 

The proper injection of Botox is an advanced technique. While the safety is excellent, it is an expensive drug / procedure.  Please consult with a talented and Board Certified Plastic Surgeon or Dermatologist who know how to properly evaluate and treat hyperhidrosis or excess sweating. 

The use and indications of Botox is vast and very interesting. You may wish to explore this remarkable drug further using the link below.

Good luck and success with your desires.

BOTOX injections to the "under arms" is safe when administered by a Board Certified physician using the proper dosages and technique. The sweat gland in our under arms have tiny muscles that contract when we perspire. BOTOX blocks these muscles. Excessive sweating called hyperhydrosois has effectively treated this. I recommend that you see a Board Certified Plastic Surgeon who can take an adequate history and examination, answer your questions and concerns and you can see if this is something your are interested in pursuing. Best wishes, Dr. Swift

Botox injections for sweating

Botox is not dangerous for injection in the axillae (armpits) for sweating. It has been FDA approved for this use for many years. It is typically injected after doing a simple starch-iodine test to determine where you are producing the most sweat. It is very effective and seems to last quite some time following the injection.

Botox under arms

In general, botox injections are not dangerous. Using it for hyperhidrosis is one way to improve the output of sweat.
