Botox or Dysport Units for Hyperhidrosis Treatment?

A good starting point is 100 units of botox (50 units per armpit) or 300 units of dysport (150 units per armpit).  Most patients, even heavy sweaters, will get relief from this dosing.  If there is "breakthrough sweating" or if the results are short lasting (less than six months), it is reasonable to increase the dosing incrementally.  You may also want to consider miraDry.  MiraDry is a noninvasive procedure that is done in the office. It destroys sweat glands using microwave technology. Patients typically have a >80% reduction with just one treatment. It costs about $2000.

Typically 50U of Botox of 150U of Dysport is used per axilla. The results typically last 4-6 months. You can increase the amount depending on your results. Some people do need more. Hope this helps. 

Botox has been FDA approved for Axillary hyperhidrosis since 2004.In our office, we have had good experience with Botox injections to the armpits.  We have treated patients, staff, and family members.  We typically use 50 units per armpit.   I have had a couple of patients tell me it is the first time they wore a powder blue shirt in years. The red carpet models also like to do this before big events.  Jeffrey J. Roth, M.D., F.A.C.S.Board Certified Plastic SurgeonLas Vegas Plastic Surgery

Our office specializes in Miraday. Miradry just got FDA clearance for elimination of all hair colors under the arm. It also has clearance for the elimination of underarm sweating and odor. Much cheaper than botox and permanent.

Usually the amount of Botox used to treat hyperhidrosis is 50 units per axilla and the amount of Dysport is normally 150 units per axilla. This can vary depending on how large the area is and how much you sweat. The treatment normally lasts anywhere from 3-6 months on average. If the treatment only lasts about 3 months for you, you may need more units. It is always best to have a consultation with a physician in order to determine if you are a candidate for treatment and how much you will need.

Botox and Dysport is a great option and highly effective helping excessive sweating, most patients require 50 units per axilla with Botox or 150 units per axilla with Dysport. Its best to seek a reputable provider with much experience in treating Hyperhidrosis

Botox and Dysport both are good choices for hyperhidrosis.  I prefer Botox toxin as I have more experience with this agent for this application.  The dosage is based on the surface area needed for injection.  

I would recommend starting with 50 units of Botox or 150 units of Dysport (3:1 ratio of Dysport:Botox).  This would provide anywhere from a 3-6 months relief.  If you find that it lasts closer to 3 months, then I would increase the dosage the subsequent visit to see if I could get more longevity.  

Typically we use 50 units Botox for each armpit, for a total of 100 units Botox.  For Dysport, this equates to a total of 300 units Dysport.

All of the studies of Botox and Dysport show that roughly 2.5 units of Dysport are required for the same effect as 1 unit of Botox. Thus, each armpit would require 50 units of Botox or 125 units of Dysport for full effect. I hope this is helpful.Stephen Weber MD, FACS
