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 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.

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.
