Can I use a product for athlete's foot for sweating feet?

Okay, so my feet are get really sweaty and so do my hands. I know it can be a disease, but I still need to get checked out. I am so fed up with this that I will do anything to cure it just a little ! My aunt gave me this spray for athlete's foot, and she said she used it on her feet for the same thing and it worked great! So, any suggestion or advice would be appreciated.
