Botox(c) injections are used for treating hyperhidrosis (excessive sweating) on the body, typically the armpits, feet, hand or back.The Botox(c) works to block the action of the nerves which activate the sweat glands thus reducing the amount of sweating. Typically patients will have treatment once a year, some find they experience more sweating in the summer months, while for other patients it may be the winter months while wearing more clothing.
