Clinical therapeutic Botox injections

Treat excessive sweating


BOTOX® therapeutic injections are used to treat hyperhidrosis, commonly referred to as excessive sweating. The objective is to reduce the excessive sweating, which is caused by dysfunctional signaling between nerves and sweat glands.

Hyperhidrosis or excessive sweating

Hyperhidrosis is a dysfunction which causes “excessive” sweating. Often of unknown cause, hyperhidrosis can touch different areas of the body such as underarms, hands, feet, face and head. However, we believe hyperhidrosis could be hereditary.
Furthermore, some medical conditions such as diabetes, menopause, thyroid disorders, anxiety disorders, etc., could be related to excessive sweating. We estimate the number of Canadians affected by some form of hyperhidrosis to be 910 000. 30% of the latter have family history. For a better quality of life; hyperhidrosis does not put your life in danger, but it does hugely compromise your quality of life and can also have direct consequences on your life!



Master excessive sweating

The good news is that excessive sweating (hyperhidrosis) is treated with success. There can be more than one good way to treat it. Here are options:

  • BOTOX® focal injections interrupt the signal between nerves and sweat glands
  • Topical treatments, such as the use of aluminum chlorohydrate, that block sweating
  • Oral medications treat underlying dysfunctions
  • Iontophoresis, which consists of applying a light electrical current on the affected areas
  • Surgery allows to cut the nerves that cause excessive sweating (special cases only)

BOTOX® injections are efficient, safe and simple!

Botox® focal injections are an efficient solution for the treatment of excessive sweating. In a study conducted on hyperhidrosis of the armpits, 95% of the patients responded to the treatment with an average sweating reduction of 83% in one week only. Furthermore, the effect generally lasts up to seven months. BOTOX® injections are the only prescription drugs approved for the treatment of axillary hyperhidrosis. BOTOX® injections have been used for many years now to treat diverse conditions. Thus, they are approved in Canada to treat muscle spasms affecting the eyes, neck and limbs, as well as to relieve muscle spasms in children, of two years old and up, suffering from cerebral palsy. A small dose of medicine is administered via intradermal injection in the affected area, using a very fine needle. The needle is placed just under the skin, so that the discomfort is minimal. If you are scared of needles, you can also ask for a local anesthesia at the point of injection, right before the treatment. During the week following the treatment, you will notice an important reduction of the sweating in the treated regions.

Answers to your questions


Basically, the process to get some help is simple:

You need to verify with your doctor if you are eligible for a reimbursement by the Régie d’assurance-maladie du Québec (RAMQ). However, certain conditions apply.

If not, many employers offer a complementary insurance system to the RAMQ. It is therefore possible that your private insurance company covers a fraction of the cost related to the treatment. Ask your employer for more information.


The possible side effects are minimal, not frequent and only found at the site of injection (ecchymosis (bruises) and pain).
