Is Botox under your arms safe and what will it do to the rest of your body?

Yes. This procedure is safe and effective. Excessive sweating from the underarms can be a real problem. There are two solutions currently including neuromodulators (Botox & Dysport) and MiraDry. We have had great success with MiraDry and it is the only permanent underarm treatment available. 

When using MiraDry it is common to require a second treatment. Most people only need one treatment (72%) while much less require a second (28%) treatment. This is the best technology that has been developed for his issue so far. 

Botox has been FDA approved for Axillary hyperhidrosis since 2004.In our office, we have had good experience with Botox injections to the armpits.  We have treated patients, staff, and family members.  We typically use 50 units per armpit.   I have had a couple of patients tell me it is the first time they wore a powder blue shirt in years. The red carpet models also like to do this before big events.  You will still sweat with exercise.  You won't harm yourself by controlling excessive sweating.Jeffrey J.

Botox is a great option since it stays locally and does not diffuse systemically throughout the body.  Botox can last 6-9 months (lasts longer for sweat glands than for muscles).  For patients who want a more permanent reduction, consider the use of Miradry or Radiofrequency needling.
