BOTOX® Treatment of Hyperhidrosis

Sweating, especially under the arms, is the normal way your body tries to cool off. When sweating becomes excessive, medically known as the condition hyperhidrosis, this can be can be embarrassing, uncomfortable, stressful, and disabling. 

The following information explains how BOTOX® treatment for excessive underarm sweating works and what is involved with the treatment.

Answers To Common Questions


What is Hyperhidrosis?

Hyperhidrosis, or excessive sweating, is a condition that affects millions of people around the world that is caused by overactive sweat glands. Hyperhidrosis can affect various parts of the body including the hands, feet, or underarms. Hyperhidrosis may be an inherited trait or physiological condition that stops the body from properly regulating its temperature.


What is BOTOX® treatment?

BOTOX® is a natural, purified protein that temporarily blocks the release of a chemical that signals perspiration, helping to reduce excessive sweating. The active ingredient in BOTOX® treatment is derived from bacteria in much the same way penicillin is derived from mould. It is manufactured in sterile laboratory conditions.
BOTOX® is a prescription-only medicine and treatment is only available from a qualified medical professional. It is registered for the treatment of severe axillary hyperhidrosis (excessive underarm sweating).
BOTOX® has been used clinically for nearly 30 years to treat a wide range of medical conditions including cerebral palsy, strabismus (crossed eyes), blepharospasm (uncontrolled blinking), and severe neck spasms. It has been thoroughly tested in clinical trials and has been found to be a very safe treatment when injected by a trained professional. 


How does BOTOX® treatment work?

BOTOX® can be used to treat excessive underarm sweating by targeting sweating at its source. Once injected by your doctor, BOTOX® enters the specific glands in the underarms and blocks the chemical responsible for excessive sweating. 
It is important to know that while BOTOX® will help reduce excessive sweating, it will not reduce the normal amount of sweating the body needs to maintain temperature as this is regulated by a different chemical than the one that causes hyperhidrosis. 


What does BOTOX® treatment involve?

BOTOX® treatment is a non-surgical procedure whereby a small amount of BOTOX® is administered into the skin of the armpits by a trained medical professional using a very fine needle. The procedure takes around 45 minutes. We may do a starch-iodine test before injecting to see where exactly you are sweating excessively.
Discomfort is typically minimal and brief. We recommend not doing strenuous exercise for the rest of the day of injection, but normal activities can be resumed the following day. 
After the injection, it takes about 7 days for the BOTOX® treatment to take full effect.


How long does BOTOX® treatment last?

After the first treatment, the effects of BOTOX® last on average of 6 months. However, the amount of time BOTOX® remains effective may vary from person to person. When your symptoms begin to return, see your doctor. 


Are there any side effects?

As with all medicines, BOTOX® may cause some side effects. In the amounts used for the treatment of hyperhidrosis, the side effects are usually temporary and localised to the area of injection. The most common side effects for primary hyperhidrosis are a perceived increase in sweating in areas other than the underarms, pain at the injection site, pain, hot flushes, and transient arm weakness. If you have any questions about side effects, please ask your doctor.


How long has BOTOX® been used?

BOTOX® treatment has been used in Australia and New Zealand in therapeutic treatments for over 20 years. It was first approved for use in Australia for movement disorders (eye & face) in 1993 and for eye spasms and crossed eyes in New Zealand in 1991.
