Botox for Hyperhidrosis:
Another very popular method to treat focal hyperhidrosis is the injection of Botox. It is a well known chemical structure used a lot by plastic surgeons to treat wrinkles. Over the years more clinical indications were added to the list and now Botox is used for different medical and surgical specialties. Botox has some chemical activity that amongst others competes and blocks the transmitter which is secreted by nerve endings for the production of sweat.
In cases of focal hyperhidrosis Botox was found to be of temporary help mainly in cases of axillary (armpit area) sweating. It has a temporary effect which can last between two to six months. It is also approved by the FDA for that purpose. On the other hand in cases of palmar (hands) and plantar (feet) hyperhidrosis, Botox is not FDA approved. Pain can be a problem when injected into the palms or the plantar surfaces (hands and feet). Some sort of local or regional anesthesia may be required. On the other hand the pain is very well tolerated when injected into the armpit area.
What is Botox:
Botox is a derivative of the botulism toxin but in small amounts, and injected into the right places, can be used safely. It is produced from spore forming bacillus Clostridium botulinum. The way it works is by blocking the neurotransmitter responsible for sweat production. A new product by the name of Myobloc is also available for the treatment of focal hyperhidrosis especially axillary hyperhidrosis (armpit sweating). Basically this is a different name for the same product. It is based on certain toxins produced by bacteria and perfected for the use in cases of hyperhidrosis.
Effectiveness of Botox with Hyperhidrosis:
With regard to effectiveness of Botox for hyperhidrosis it should be remembered that Botox has a limited and temporary effect. Repeated injections will increase the bodies resistance to the material. It is more effective in cases of armpit sweating (axillary) and less in cases of palmar and plantar hyperhidrosis. Another drawback may be the cost which is typically several hundred dollars for each treatment. In order to offset the price patients can try and ask for insurance coverage.
If money and pain are not of an issue then Botox can be tried to treat focal hyperhidrosis of the armpit. With regard to palmar (hand) and or plantar (feet) hyperhidrosis at present there is no good indication to the usage of Botox.
