BOTOX® is injected into the skin to treat the symptoms of severe underarm sweating (severe primary axillary hyperhidrosis) when medicines used on the skin (topical) do not work well enough.

Keep in mind that BOTOX® treatment is not appropriate for all sufferers. You and your practitioner will make the determination if it’s right for you. During the procedure at the doctor’s office, a small amount of BOTOX® is injected into the affected underarm area through a very fine needle. In a short appointment with your dermatologist, about 15 injections are made to the underarm area. The actual procedure takes about 10 to 15 minutes and lasts up to 201 days or 6.7 months. You should notice a significant reduction in underarm sweating within 4 weeks of your first treatment.

Botox as a Treatment Option

Most of those who suffer from the problem of excessive underarm sweating would swear that conventional remedies like antiperspirants and oral medication or even surgery have no long-term impact on their condition and they would probably be right. A big advantage of Botox is that it provides relief from excessive underarm sweating for at least six months and even 10 months in some cases.

In the treatment of primary axillary hyperhidrosis a small dose (about 15 drops) of Botox is injected into the skin of the underarm of the patient to prevent the release of a chemical called acetylcholine which carries signals from the sympathetic nervous system to the sweat glands in the underarm to stimulate sweat production. The injection of the Botox as I said earlier simply blocks the nerves in the underarm that cause excessive sweating and thereby prevents sweating in that area.
