1 Unit of Botox 2.5 Months Ago for Underarms. Is It Safe to Use 1 Unit This Soon After?

Question

I had 1 unit of botox between the two armpits. I have an appointment in less then twenty four hours to have another unit done. Which is great it works so well but I'm not sweating again and it's only been two and a half months! Is this safe to have?

Sonia Badreshia-Bansal, MD · Answer

Thank you for your question. Botox for hyperhidrosis usually takes 100 units (50 units per armpit) and can last up to 9 months.  I would recommend consulting with your injector and plan to do a maintenance or follow up in 6 months.  I would recommend being treated under the supervision of  a Board Certified Dermatologist or Plastic Surgeon for safest and best treatment option. I hope this helps.

It is safe to reinject but more expensive than if you were to wait for the return of symptoms.  I typically inject 50 units or more per axilla.

I think you mean one vial of Botox which is equivalent to 100units.  I usually use fifty units on each axilla with results that usually last 6-9 months. I would not advise another treatment at 2.5 months. The physician who treated you will likely help you time your next dose.  Another option is MiraDry, which uses microwave energy to permanently destroy your axillary sweat glands.

I think you must be mistaken with the dose of Botox you received previously.  1 unit of Botox between the underarms would not do anything.  Normally, I use 50 units of Botox for each arm.  In most cases, the effect from Botox lasts longer in the underarms than for cosmetic purposes on the face and I have seen it last a year or more when used for sweating under the arms.  I would check on the dose you actually received and it is possible that you do not need another treatment at this time, especially if you are not having any sweating now.

One unit of Botox won't go far in your underarms - are you certain it wasn't 100 Units? Typically treatment for hyperhidrosis of the under arm area is done with a large amount of product - and should last several months if injected properly.
