What Is Botox Injections for Hyperhidrosis?
Botulinum toxin (known as Botox Injectable) is a drug that temporarily paralyzes muscles to treat certain muscle conditions, reduce wrinkles or stop sweat.
In 2004, Botox Injections became FDA approved for treatment of Axillary Hyperhidrosis (excessive underarm sweating).
Botox injections work by blocking the secretion of the chemical that activates sweat glands – essentially turning them off. The injections are very shallow – the medicine is injected just below the surface of the skin, where it remains.
While everyone breaks down the Botox injections differently, typically you can expect three to six months of results from your injection. It is important to note that stress and exercise can cause the Botox injection to fade quicker.
Research shows it is safe to treat excessive sweating on:
- face (craniofacial)
- other relatively small body areas (like under the breasts)
Botox injections have been shown to result in an 82-87% decrease in sweating in the underarms.
Patients typically notice results in about two to four days after treatment. They usually enjoy the full effects within two weeks.
Some patients do experience the benefits for up to 12 months. It is very specific to the individual and their lifestyle.
Sweating is a vital part of the body’s processes – it helps with temperature control. It is safe to diminish or prevent sweating in small, localized areas because you are only impacting a small percent of the body’s “cooling system”. For example, the sweat glands in the underarms are only 2% of all the sweat glands in the body.
Botox injections are found to be about 80-90% effective in the hand and injections last for about six months. People do report temporary pain and weakness when receiving injections in the hand.
Botox can also be used for excessive sweating in your feet, known as Plantar Hyperhidrosis. Note that patients report more pain during plantar injections and some say the treatment is less effective in this area. Speak with your doctor to determine if this is a viable solution for you.
Botox injections, on the whole, are a very safe and effective way to combat sweat problems. SpaMedica is well versed in this technique and is here to discuss your questions.
