Botox alters the function of certain neurotransmitters. They are chemical substances in the body that instruct the body to react in a certain way. Botox prevents the nerve signals that tell the sweat glands to activate, controlling sweating in the injection area.

The cost.

Botox injections can be expensive. The approximate cost for both armpits is $1,000, and a person needs to repeat the treatment every 7 to 16 months, so expenses can add up.

Health insurance companies may cover the cost of Botox for excessive sweating. However, some may do so if the person shows ineffectiveness of other treatments.

Use on other parts of the body.

Doctors may prescribe Botox to treat excessive sweating in other areas of the body prone to excessive perspiration. These include:

The hands
The feet.
The back.
The chest and under the breasts.
The thigh.
The head.
The face
The nose.
The procedure.

A dermatologist or a certified physician for Botox can perform the injections in their clinic. Experienced medical professionals can inject the armpits in 10 minutes or less.

For this procedure, a medical specialist injects very small amounts of Botox under the skin. They usually inject it in a grid pattern, with injection sites spaced about 1-2 cm apart.

Before injecting the skin, the doctor may numb the area with ice or a local anesthetic. This will help alleviate any pain or discomfort.
