Hello djanezd, Botox can be life changing for those suffering from excessive sweating of the feet, hands, armpits and head. Helping people with this problem is a very rewarding part of our practice. The cost will depend on dose and frequency of the treatment you require. Many extended health benefit plans will cover a portion or all of the cost of the botox used in treatments like this, and some plans will even pay the doctor injection fee. I recommend you start by finding an experienced physician; one way to do this is to inquire with your health plan regarding coverage. You will need between 50 and 100 units per foot every 3 to 6 months. Larger doses last longer, and regular dosing will require less frequent treatments. If your first treatment has inadequate response, try at least 1 or 2 more treatments in close succession before giving up. It isn't unusual for long time heavy sweaters to need this to get things under control. We charge an injection fee of $250.00 (Canadian) for those who provide their own botox. Purchasing directly from our clinic will often provide a cost savings. Botox cost varies from province or state, so be sure to check the price with your injector at the time of consultation. Good luck. For those suffering with hyperhidrosis, I definitely recommend giving botox a try - it works!
