About Botox® for Hyperhidrosis (Excessive Sweating):

Hyperhidrosis is a disorder of excessive sweating that interferes with a patient's quality of life. Commonly affected areas are the axilla (armpits), forehead, hands, and feet. Botox® is injected into the skin region with excessive sweating and works by reducing the neurologic signal to the sweat gland. This leads to a significant decrease in the amount of sweat produced in that region. Some patients may notice complete cessation of sweating in that region, while others will notice a significant decrease that improves their quality of life. 

The axilla is treated with 50 units of Botox® per side, on average, with 100 units needed to treat both axilla.  This is completed by an average of 25 injection sites on each axilla with 2 units given per injection.  Patients may require more or less units depending on the surface area being treated.  

For the forehead, hands, and feet, the number of units is dependent upon the surface area of these regions.  The forehead is treated in three horizontal rows with one row below the hairline, along the hairline, and 2cm behind the hairline.  With the hands and feet, the skin is marked out in a grid and the number of injections is determined by the grid.  On average, patients require 50 units per hand and 50 units for the forehead as well, but will vary per patient.  

Number of treatments:  

Axillary treatments last between 6 and 12 months, with the average being 8 months. Hand and feet treatments tend to last around 6 months, and forehead lasts around 5 months. Repeat treatments would be scheduled when the patient notices the bothersome sweating returning. 

Appointment Time (may vary):

30 minutes per region treated

Downtime: 

None. Patients can expect mild redness and soreness around the injection sites when the axilla and forehead are being treated. If the hands / feet are being treated, they may require a nerve block and should have a friend drive them to the office because of decreased hand function while the block wears off.  

Ideal Candidate: 

Patients with excessive sweating that interferes with their quality of life and who are unhappy with results from topical treatments.
