BOTOX and excessive underarm sweating

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Depends. The amount needed is dependent on the area. Excessive underarm sweating takes about 100 UNITS of BOTOX. For crania-facail HH (Face), it usually requires 40 units depending on the areas. If the scalp is involved up to 200 units is required. 

In Australia, underarm sweating is partially covered under Medicare for underarm sweating, but NOT facial sweating. 

All the best

Botox dosage for hyperhidrosis

Underarms usually require a higher dosage because of the larger area treated. As a result, in general they will have more units administered.

Thank you for your question. I would recommend following the standard reconstitution by the Allergan (Botox manufacturer) company. About 100 units of Botox (50 units each armpit) total used for hyperhidrosis. I hope this helps.

The recommended dosage for hyperhidrosis is 50 units on each underarm, 100 units total. Normally should be reconstitute with 2.5 saline but every physician has their own dilution that can vary

I use the same amount of saline to mix the Botox for underarms and facial treatments.  The recommended amount of saline is 2.5cc of saline per 100 unit vial of Botox.  I usually use between 70-100 units for both underarms.  Take care, Dr. Groff

Axillary hyperhidrosis and Botox

The recommended dosage is 50 units per underarm. Even in a diluted solution, 1 unit = 1 unit, it just may take more volume of injection. Best of luck!

Botox for treatment of axillary hyperhidrosis

Depending on the physician the concentration may or may not differ, but the primary difference is the total dosage.  A typical dose for each armpit is 50 units (for a total of 100 units), divided over 20-25 sites.

Concentration of Botox to treat face vs. underarms

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The same concentration of botox is used to treat the underarms or the face for sweating.  However the total number of units used will be greater for the treatment of the underarms.

Botox Concentration for Armpit Sweating

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Ms. Willym,

The major difference in Botox injection for the face and the armpit is the amount of Botox(total unit of Botox) used.  The units injected for the armpit are much greater. I tend to use the same concentration whether it be the face or the armpit.  However, there are times when I will use a more dilute concentration in the armpit if I need to spread the same number of units to a bigger surface area.  On the face more concentrated solution is used to keep the Botox in the specific area injected.  The most important factor in Botox injection is to tailor the injections to the patient.  Although consistency is important, the patient's needs are the most important factor.  Thanks for the question and Best Wishes!

Botox for Hyperhydrosis (Sweating Under the Arms)

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Hi Willym,

The same concentration of Botox is used under the arms as on the face to control hyperhydrosis (Sweating).  It is the total number of units of Botox that is much greater for stopping underarm sweating.  Good luck and be well.
