How Much Botox Units is Needed to Treat Underarm Hyperhidrosis?

I like 50 units per arm pit.  One of my nurses or my PA performs the procedure.  It's a little time consuming, we book an hour for treatment which allows for time to numb the area with Betacaine, Lidocaine and Tetracaine (BLT) cream.  Nearly all patients continue to return for treatments, which tells me it works.  I am hopeful that the Botox cream proves effective, which would be nice, especially for hand and foot sweating.  Those areas are painful to treat.

It takes about 50 units of Botox per arm to correct the medical condition known as hyperhidrosis, or excessive sweating. Botox is not a permanent cure. Results only last about three to four months and then the procedure must be repeated. However, my patients who have had Botox to control this embarrassing condition have been very happy and continue to be treated. I hope this helps.

Most patients have gone through dry-sol and other treatments.  We have the patient come in for an evaluation.  We will usually place a topical numbing cream and then treat with 50 units of Botox in each armpit.  Some of these patients are the happiest in the practice.  I had one patient state that this is the first time in years that he had worn a powder blue dress shirt.  It typically lasts about 6 months.  We have had others that lasted considerably longer.

As the other panel members have indicated, most will start with a minimum of 50 units of Botox per underarm for a total of 100 units per treatment.  Our patients have found value with this treatment especially when done before a special event (ex: wedding) or for hot, humid seasons.

TIP:

We offer a discount on the cost of the product for these treatments since a patient is using an entire vial for one treatment.  We would encourage you to ask for the same.

I will start off with 50 units, and sometimes go higher depending on the response. I have replaced Botox with the PitStop procedure for permanently reducing underarm sweating.  As a one-time treatment it works better and is less expensive.

Hi DVicious, thank you for your question!
It takes approximately 50 units Botox per underarm. The Dysport equivalent would be 150 units of Dysport per underarm. Performing a starch iodine test on each underarm prior to injections can help identify the exact areas where your sweat glands are most concentrated. 
I've created a video that reviews treating underarm sweating with Botox. I hope you find this helpful in your research.

Thank you for your question DVicious. I understand your concern. Botox is a purified protein used to address wrinkles associated with facial expression. When injected into the skin Botox will relax the muscles and smoothen out the overlying wrinkles. The most common areas of treatment are in the upper face. These include the horizontal lines seen on the upper forehead when one raises the brows, the vertical lines seen between the brows when one frowns (frown lines), and the crow's feet seen around the eyes when one smiles.It is difficult to make an assessment without a formal exam where the entire medical history is reviewed. However, I hope the information provided here is useful.Excessive sweating, a condition known as hyperhidrosis can be a serious concern for some people. Excessive sweating can occur even when it is not hot. It sometimes occurs when a person is nervous. This can become very embarrassing for a person, especially when it happens frequently. The most common areas of concern include the underarms, palms of the hands, and soles of the feet. Fortunately, Botox is an easy and effective treatment for excessive sweating. These areas are more sensitive and therefore numbing cream is usually applied on the area for about 15 minutes prior to the treatment. To determine exactly where the sweat glands are, sometimes a test is performed called the starch iodine test. Iodine is placed on the area of the skin which will be treated. The areas with more sweat glands will appear dark. This allows the provider to know exactly where to place the product. Despite this, typically the entire area is treated and the product is placed to cover the entire area. Usually 50 units of Botox are used on each side. Some people enjoy their results for six months or more. Similar to when Botox is used for cosmetic purposes, periodic maintenance treatments are required.
With any injection, there are risks such as pain, bleeding, bruising, redness, swelling, tenderness, and infection. We take special precautions to minimize these risks such as using a painless technique. We also treat bruises with a laser as early as the next day. Bruises usually resolve within two weeks if untreated. After a laser treatment bruises usually resolve in 1-3 days, but may still take two weeks for full resolution. In addition to these risks, with Botox there is also a risk that the product spreads or diffuses to nearby structures. Spread to nearby muscles can lead to side effects such as the temporary appearance of droopy eyelids or a temporary asymmetric smile.

After a Botox treatment, I recommend that my patients avoid heat exposure, alcohol consumption, and strenuous exercise for 24 hours and not lie down flat for four hours. This is because all of these activities may possibly lead to the movement of the product and consequent side effects such as droopy eyelids. Although there have been no definitive studies shown that these actually occur and some physicians do not provide such aftercare instructions, in the absence of data I err on the side of caution and recommend that my patients avoid such activities.

Please consult with a doctor for specific recommendations. Good luck!

Botox for hyperhidrosis (underarm sweating) typically requires about 50 units per underarm (100 units total).  Botox for underarm sweating is not a cure.  It wears off after several months so you need to keep coming back for more injections.  You should consider doing MiraDry for underarm sweating.  It permanently reduces underarm sweating after one or two treatments.  

On average, our center uses 50 units of botox per side or 100 units total for most patients. The actual procedure takes less than 10 minutes. However, we advise our patients to come in earlier for prepping of the area to be injected. 

it's quick and efficient...should be in and out of the office in less than half an hour including numbing time...while some doctors like to use more to start with, it may be a waste of money...and actually I perform all of the treatments...
