How much botox can be given to the groin area for excessive sweating and will the sweat move elsewhere?

It's safe to receive more than
100 units but difficult to predict how much compensatory sweating you'll
have in other untreated areas. Since our bodies all adjust
differently to sympathectomies and Botox for hyperhidrosis, the only way
to know for sure is to treat the affected areas and see how your body
responds. Good luck!

I do this frequently, especially in athletes and people who have chronic rubbing and irritation in the buttock, groin areas.  I typically start with 50-100 units in the groin.  If this is enough then I increase, there is no reason you cannot do more.  Best, Dr. Emer.

I don't know if anyone can assure you that compensatory hyperhidrosis will not occur after treatment of the active area. Compensatory hyperhidrosis is probably the most common "side-effect" of any treatment. The real plus for sympathectomy is that it's result is permanent. You might want to consider going that route again.             jlr
