Iontophoresis was originally developed as a way to administer mediciation without the use of needle injections. The medication is absorbed throught the skin using iontophoresis. So adding Avert, etc. to your Iontophoresis treatments will not actually help your sweating stop in the manner that Iontophoresis normally does. You will simply be administering the medication through your skin instead of orally. People who add Avert, etc. still get the same side effects that you would normally experience if you took it orally.
