Botox or Dysport Units for Hyperhidrosis Treatment?

How many units of Botox or Dysport are needed on average in each armpit to block excessive sweating? Also, can I expect my treatment to last 3-4 months like it does on the face? Thanks!

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 versus Dysport For Hyperhidrosis

+1

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.

Botox and Dysport units for hyperhidrosis

+1

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.

Fortunately an Easy Answer...

almost by convention 50 units of botox under each arm is the way to begin...so a total of 100 units altogether...some people may need a bit more but overwhelmingly this dose is a good bet for average sized people...and the effects generally last between 6-12 months with an average closer to 9 months...imagine how nice it would be not to have to worry about excessive sweating and stained clothes...all with one simple relatively inexpensive treatment session...

Botox for Underarm Sweating - Hyperhidrosis

+1

The amount of Botox varies for those with small body surface area (90 pound teenager) versus a 240 pound body builder who has a large axillary surface. Anywhere from 50 - 100 units are used per axilla. I don't use Dysport as Botox has stood the test of time in my practice with over 1,000 patients treated with Botox for hyperhidrosis - and quite effectively - with the very rare patient who finds minimal relief.

Botox or Dysport for Hyperhidrosis

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.

Botox or Dysport Units for Hyperhidrosis Treatment?

+1

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.

Botox injections and retrograde suction curettage for axillary underarm sweating

+1

Botox injections are effective temporarily for underarm sweating, whereas a more definitive treatment in my practice would be Retrograde Suction Curettage of the axilla.  I would also recommend Miradry procedures, which are effective with one or two therapies.

Botox Units for Hyperhidrosis

+1

Good question.  In general, 50 units of Botox per side for a total of 100 units Botox is necessary for an effective dose.  For Dysport, 150 units per side or a total dose of 300 units is necessary.  100 units of Botox costs about the same as 300 units of Dysport, so there really is no cost difference.  You should see an effect in 3 to 7 days and the effect should last 4 to 6 months.

 

Good Luck.

Botox and Dysport both fine options for hyperhidrosis

+1
50 units of Botox or 150 units of Dysport typically injected for each armpit. Dysport may have a slight advantage as it has slightly greater diffusion property and may cover greater area of sweat glands with the same injection insertion points as Botox.
