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

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.
