Deodorants are not designed to control sweating, they mask the odour usually associated with it.


Over-the-counter antiperspirants contain metallic salts. These salts have been found to block sweat ducts, reducing the amount of perspiration that reaches the skin.

Clinical Antiperspirants

Your doctor may recommend a stronger antiperspirant for your severe underarm sweating. Like other antiperspirants, these also work by blocking sweat ducts, thereby reducing the amount of perspiration that reaches the skin.

Injectable Treatments

What is an injectable treatment?

Injectable treatments involve injections in the underarm area, which help to control the symptoms of severe underarm sweating by temporarily blocking the chemical signals from the nerves that stimulate the sweat glands. When the sweat glands don’t receive chemical signals, the severe sweating is significantly reduced. These injections are expected to temporarily stop the production of excessive sweat in the treated areas only.

What happens during the procedure?

During the procedure, a small amount of the treatment is injected into the affected underarm area through a very fine needle. In a short appointment with your specialist, about 15 injections are made to the underarm area. The procedure can be expected to take about 10 to 15 minutes.

Am I eligible for an injectable treatment?

People with severe primary axillary hyperhidrosis are eligible for treatment under the Pharmaceutical Benefits Scheme (PBS) if they:

  • Are over 12 years of age
  • Have previously failed topical aluminium chloride hexahydrate after one to two months of treatment or are intolerant to topical aluminium chloride hexahydrate treatment
  • Are treated by a PBS-registered dermatologist, neurologist or paediatrician


A variety of surgical approaches have been used to treat severe underarm sweating but they are usually reserved for the most extreme cases that do not respond to other treatments. Some surgical methods used include removal of axillary sweat glands and endoscopic thoracic sympathectomy. Endoscopic Thoracic sympathectomy involves interrupting the nerve signals between the spinal column and the sweat glands.
