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 for Underarm Sweating - Hyperhidrosis

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?

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, M.D., Ph.D. Lone Tree Facial Plastic & Cosmetic Surgery Center

Botox injections and retrograde suction curettage for axillary underarm sweating

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

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. see video

Botox and Dysport both fine options for hyperhidrosis

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.

Both will work well

We generally inject 50 units of Botox in each arm pit With Dysport we inject 150 units per arm pit. Botox results generally last 200 days with Dysport we are hopping it will last longer and the onset of action should be faster.

Botox for Hyperhydrosis

Whereas the Botox for the face generally lasts about three months (longer as you use it more), Botox for hyperhidrosis can last 6 months or more and is usually quite effective. I don't use Dysport yet as I have had such a good response with Botox, but I don't see any reason why it wouldn't work, once the actual dosage is delineated. Recently there are reports of laser lipolysis (SmartLipo, Pro Lipo, etc) being effective in treating hyperhidrosis and potentially with a much longer, if not... more

1 vial does it

It takes 1 vial of Botox (50 units per armpit) for underarm sweating. It seems to take 1 vial of Dysport (150 dysport units per armpit) to get the same result. Botox seems to last longer for sweating (6-9 months) than on the face. It remains to be seen how long Dysport will last but I would think at least as long as Botox.

Botox or Dysport for Hyperhydrosis; It's the Pits

Hi KB, The reccommended ratio of Botox units to Dysport units is 2:5.  Botox for hyperhydrosis takes 50 units per armpit, therefore Dysport would take 125 units per armpit.  The treatments seem to last a bit longer than on the face, up to 6 months. Good luck and be well. Dr. P

Botox or Dysport for hyperhidrosis

The standard dose of Botox is 50 units per underarm. You can expect the treatments, however, to last approximately 6 months, frequently longer when Botox is used for this medical indication. I would estimate that 150-200 units of Dysport would be needed to address the same problem, although there is not a precise conversion ratio between Botox and Dysport. Good luck.
