Plantar Hyperhidrosis treatment helps to stop sweating and makes a significant relief from symptoms. Botox® injections work best for those who have primary focal hyperhidrosis and can treat sweaty feet safely and effectively.
Before applying Botox®, an iodine-starch test may be performed to determine the area that requires treatment. A povidone-iodine solution is painted onto the area and then cornstarch is added. When the patient begins to sweat, the mixture highlights the moistened areas by forming dark marks where sweat is collecting, thereby lets the doctor know where the problem areas are. A grid is then marked on the area that is going to be treated, indicating where the injections will be placed.
Prior to beginning Botox® injections, a local nerve block is placed to numb the area in order to make the injections comfortable. The Botox® is then injected into the marks indicate. The skin of the feet can be particularly thick so multiple needles may be used. The amount of Botox® needed depends on the size of the feet. Usually, 130 to 200 units of Botox® are needed in each foot.
When Botox® is injected block the release of acetylcholine and various other neurotransmitters which prevent the eccrine glands (sweat glands) from producing sweat and thus prevents perspiration. The injections are placed directly into the affected areas.
On the recovery process, the patient should notice a significant reduction of sweating. Since there's no specified recovery period, most patients are able to continue immediately with their normal activities.
The treatment is usually effective for 3 to 4 months and the patient should normally notice the difference within the next few days after and notice a significant reduction of sweating.
