Underarm Hyperhidrosis Injections

Botox blocks signals from the nerves to the muscles. The injected muscle can't contract. That makes wrinkles relax and soften.

BOTOX (botulinum toxin type A) is used for the treatment of severe primary axillary hyperhidrosis (excessive sweating) in patients unable to obtain relief using antiperspirants.

Using local injections of BOTOX to alleviate the symptoms of hyperhidrosis is a promising approach. Research has shown that treating the armpits, hands, feet, and face with botulinum toxin is safe and effective. In one clinical study involving 322 patients with severe underarm sweating, 81% of the patients receiving botulinum toxin injections achieved a greater than 50% reduction in sweating. And, 50% of the patients had their excessive sweating relieved for at least 201 days (nearly 7 months).

Botulinum toxin is a natural, purified protein with the ability to temporarily block the secretion of the chemical in the nervous system that is responsible for "turning on" the body's sweat glands. By blocking, or interrupting this chemical messenger, botulinum toxin "turns off" sweating at the area where it has been injected.

BOTOX injections can be administered in a doctor's office, require relatively little time, and do not demand any restrictions in work or leisure activity (aside from refraining from intensive exercise or the use of a sauna on the day of the injections).

BOTOX injections do not cure hyperhidrosis; your symptoms will return gradually. Follow-up injections are required to maintain dryness. These repeat injections may be necessary at intervals varying from seven to sixteen months.
