Hyperhidrosis Treatment Toronto

Botox® for Excessive Sweating

Hyperhidrosis is excessive sweating that is not related to heat or exercise. Excess sweating under the arms (axillae) can be embarrassing. It can also ruin your favorite clothes or force you to wear layers to cover up. For people affected by hyperhidrosis, Botox injections can significantly decrease sweat production, leading to improved confidence, comfort, and quality of life.

How is Botox Used to Treat Hyperhidrosis?

Injection of Botox into the skin under the arms (axillae) significantly reduces the amount of sweat produced in 80-90% of people treated. When you have hyperhidrosis, the nerves that tell your sweat glands to activate are constantly triggering. Botox injections block those nerves from sending any signals. The activation message that those nerves would typically transmit to your sweat glands never gets delivered. As a result, your sweat glands are able to switch off.


This treatment works for the vast majority of those suffering from hyperhidrosis, presenting an effective, and relatively non-invasive, solution.

Who is a Candidate for Botox Hyperhidrosis Treatment?

You’re likely a good candidate for Botox treatment of your axillary hyperhidrosis if you:

  • Experience uncontrolled excess sweating of the underarms (axillae).
  • Are not able to mitigate your hyperhidrosis with topical antiperspirants.

For most people, a reduction in sweat production occurs within a few days of treatment. Optimal results are seen at about 2 weeks. Results last anywhere from 4-12 months.

Our Comprehensive Approach to Botox

The first step in treatment of axillary hyperhidrosis is consultation with one of our board-certified dermatologists. Once the diagnosis of axillary hyperhidrosis has been confirmed, treatment options will be discussed. If Botox is determined to be the best treatment option for you, it can often be administered on the day of your initial consultation.

Currently, Botox is only approved for use in the treatment of hyperhidrosis under the arms, known as severe primary axillary hyperhidrosis. However, it is often effective in the treatment of hyperhidrosis of the palms and forehead as well.

The treatment consists of about one dozen superficial injections into each axilla. Once the injections are completed, you’ll be able to resume your normal activities immediately. You will notice decreased sweating within 3-5 days, with peak effect by 2 weeks.
