Botox for Excessive Foot Sweating?

Thank you for your question. Botox is a very effective treatment for hyperhidrosis (armpit, hands, feet, scalp/face, etc). The dosing is typically based on areas treated but can vary around 50 - 100 units per side depending on how large the treatment area. Duration also depends on dose and technique, but can vary from 3-6 months. For the armpit region, you may also want to consider miraDry as it provides a longer lasting relief and in the long run is more cost-effective.

Not all malodorous feet are caused by heavy sweating, but it can contribute significantly to different causes whether bacterial or yeast. Numbing cream, ice and even regional blocks of anesthetic have been done to minimize the pain of injecting skin with abundant nerve endings.

We have a large hyperhidrosis practice and routinely see and treat patients with plantar hyperhidrosis.Treatment with Botox will reduce both hyperhidrosis, and by limiting excessive moisture which promotes bacterial and fungal overgrowth, will also treat bromhidrosis (excessive odor).Read my ebook about plantar hyperhidrosis on the link below. 

Botox works very well for localized treatment of focal hyperhidrosis such as axilla, palms and soles.

Botox works great for this problem just as it does under the arms.  It may need to be injected on the whole bottom surface of the foot though, not just between the toes. 
 

Botox for hyperhidrosis of the feet works well, just as it does for the underarms. But I would warn that even with a wonderful injector, great care, icing and/or cold chiller at the injection sites, your partner should expect a bit of pain. The feet are extremely sensitive and injections into the feet are painful. The pain shouldn't last longer than the injections take, really, but the injection sites may be a bit tender for a day or so. While the procedure might be a bit uncomfortable, I'm sure the outcome (for both of you!) will be worth it.

Excessive sweating, known as hyperhidrosis, can be alleviated with Botox Therapeutic or Dysport injections directly into the affected skin. For treatment of feet, the injections are usually done throughout the plantar surface of the foot, not just between the toes. This temporarily blocks the sweat glands which are responsible for excessive perspiration. These injections are typically done in a single treatment session on any area of the body and can provide months of relief. Treatments can be repeated once or twice a year to maintain dryness. The most commonly treated areas include underarms, hands, feet, and face. Many health insurance plans will pay for this treatment but only if it can be documented that you have had unsuccessful treatments with conventional therapies first.

Botox is very effective for foot sweating.  Foot odor has many causes.  Although sweat is odorless, it is associated with increasing the incidence of foot odor.  If the amount of sweat is decreased,  most the time the foot odor will decrease.

I have been treating patients with BOTOX® for hyperhidrosis of the feet for about 8 years now.

BOTOX® works very well and is very safe. I use a specialized ice technique to keep my patients comfortable. This was published in the journal Dermatological Surgery.

Dr. Derek Jones in the Beverly Hills area is an expert on the use of BOTOX®, and he or one of his associates could probably take care of your sweetheart, and will have access to my paper on the use of ice to facilitate the injection of BOTOX® for palmar and plantar hyperhidrosis.
