Don’t sweat it with Botox

2.8% of the population suffer from excessive sweating of the underarms

It’s often an awkward topic for patients to bring up – excessive sweating. People who experience excessive underarm sweating have a condition called axillary hyperhidrosis. This condition has physical and mental symptoms affecting patients’ confidence and comfort.

Thankfully Botox has been FDA-approved as a treatment for axillary hyperhidrosis. Besides the great feeling of dryness, patients appreciate:

  • No odor as the environment needed for the growth of bacteria (cause of the odor) is eliminated
  • No sweat stained clothes
  • No white residue from antiperspirants when wearing sleeveless tops

How it Works

Botox prevents sweating in the specific area where it’s injected. When you receive Botox injections directly into the armpits, your overactive nerves are essentially paralyzed. When your nerves can’t signal your sweat glands, you don’t sweat.

Botox essentially “inhibits nerve transmission to the sweat glands under your arms, slowing down the production of sweat and reducing output by as much as 90 percent”, according to Dr. Anatoli Freiman of the Toronto Dermatology Centre.

Preparing for Treatment

Botox injections are a simple and quick procedure done right in your doctor’s office. Doctors typically ask that you avoid shaving your armpits two or three days prior to your appointment.

Normal activities can resume immediately after receiving Botox injections.

The Treatment

Botox treatment for axillary hyperhidrosis usually requires 100 Units. I try to use 80 Units, if possible. Talk to your doctor or insurance company about getting your Botox injections covered.

I inject the Botox medication just below the surface of the skin using a fine needle. You’ll receive several injections that form a grid pattern around the area of concern. You may receive something to prevent minor pain, like ice or a numbing agent but the treatment is relatively painless.


Botox is a highly effective treatment for excessive sweating. For many people, it drastically improves their quality of life. Patients describe the treatment as “liberating” and “life changing”.

Botox injections work best when given by an experienced practitioner.

The effects of Botox are temporary, which means you’ll need more injections in the future. For underarm sweating, dryness can last anywhere from four to fourteen months. My experience is that the sweating stops for on average 6-8 months, with a small percentage at 4 months and the longest 14 months.

Botox might not totally eliminate the need for antiperspirant, that’s a judgment call, but every patient I’ve treated says within 7-14 days they have no need for antiperspirant or deodorant. Patients with hyperhidrosis are obviously very very pleased with the results. I’ve also treated male and female patients with normal sweating who love not wearing deodorant.

Patients love the “dry feeling”. Even individuals who only sweat a little say the “sticky feeling is gone and it feels amazing!”.
