If you have searched around for treatment for excessive underarm sweat, I'm sure you would have found many, including antiperspirants, oral medications, botox injections, iontophoresis, surgery, and perhaps several more. Antiperspirants are a common treatment method for mild cases of sweating, but it is actually only a short term cover up for excessive sweat.
Botox injections can be quite effective, but they are very expensive and can be very painful. Each treatment can costs up to $1400, and would typically need to be repeated every six to eight months.
Surgery, which involves removing the sweat glands, or cutting the nerves near the sweat glands, may be able to cure excessive sweating in the underarms. But it can also cause compensatory sweating (which is sweating in other areas of the body), because the body is still sweating profusely and needs to find another way to release the sweat.
If you are looking to treat excessive underarm sweating, it is almost always a better idea to treat the causes of sweating, instead of using short term methods to hide the symptoms. Disguising the symptoms of underarm sweating takes a lot of time and effort, and is also more expensive in the long term.
