BOTOX® for Excessive Sweating/ Hyperhidrosis FAQs:

What is Hyperhidrosis?

Hyperhidrosis, or excessive sweating is a condition that affects millions of people around the world. Uncontrolled sweating can occur in various parts of the body including the face, hands, feet or underarms (axilla). Although high temperatures or stress can increase perspiration, they don’t cause hyperhidrosis. Instead, hyperhidrosis may be an inherited trait that stops the body from properly regulating its temperature or it may be a symptom of other conditions including anxiety disorders, thyroid malfunction, nerve damage and menopause. Hyperhidrosis can also occur as a side effect of a medication. Until now, excessive sweating has been difficult to control. Health Canada has approved the use of Botox ® for the long lasting treatment of this disorder that affects such a large part of the population.

How does BOTOX® work?

BOTOX® is a highly purified naturally occurring protein derived from the Clostriduim Botulinum bacteria. Unlike topical treatments, BOTOX® targets sweating at its source. With several tiny injections the BOTOX ® is delivered into the specific glands responsible for sweating. BOTOX® blocks the release of a chemical that signals the perspiration response. Clients treated with BOTOX® notice a remarkable improvement in their symptoms. In clinical studies, 95% of patients with hyperhidrosis that was severe enough to interfere with their daily lives experienced the benefits of BOTOX® after just 1 week, with sweating reduced by an average of 83%.

How long will it work?

After the BOTOX® treatment, the average duration of effect is 7.5 months with 38.6% of clients achieving duration of effect for more than 1 year. The amount of time BOTOX® remains effective may vary. When your symptoms begin to return, phone the Dermatology Rejuvenation Centre at 425-2956 to schedule another appointment.

Is this treatment safe?

BOTOX® has been used successfully to treat a range of medical conditions for more than 20 years. Side effects, if they occur, are temporary. The most common side effects with BOTOX® for axillary hyperhidrosis were a perceived increase in sweating in areas other than the underarms (4.5% of patients), pain at the injection site (1.7%), pain (1.4%), or hot flashes (1%).

What is treatment like?

The needle used to deliver the BOTOX® is very fine and many patients are pleased by the minimal discomfort of the treatment. We advise our female patients to bring a sleeveless t-shirt or tank top for their injections to provide additional privacy. Normal activities may be resumed immediately following the procedure.

What is expected after the treatment?

After BOTOX® treatment it is not uncommon to experience some minor discomfort, swelling, redness or bruising at the injection site. Tylenol or ice packs may be used to reduce swelling and relieve discomfort. ASA (Aspirin) should be avoided to reduce bruising in the treated area.

Instructions for patients following injections:

- Wear “washable” clothing to your appointment. Gauze may be placed over the treated area and we ask that you leave it in place for the remainder of the day to prevent soiling your garment.
- As with any injection into the skin there is an increase risk of infection. Be sure to wash the affected area daily and notify the nurse at the clinic at 425-2956 if redness or swelling worsens. Refrain from tub bathes, jucuzzi’s and pools for the first few days after treatment to prevent infection in the treated site.
- Exercise is to be modified for the remainder of the treatment day. Typically the area will return to its normal appearance with in the first 5-7days.

Is this treatment for everyone?

There are very few restrictions regarding BOTOX® treatments for Hyperhidrosis. Clients who are pregnant or breastfeeding, have a known neurological disorder (i.e. Myasthenia Gravis or Eaton Lambert Syndrome), allergy to the ingredients in the commercial formulation, specifically albumin, should generally not be treated.
