Ear mites help

Hi, my 4 month old puppy just came home on Tuesday and appears to have ear mites. He is constantly trying to scratch his ears, shakes his head, and loves walking over to me for a nice ear rub. The puppy is seeing the Vet tomorrow but I was wondering if anyone has any ideas of ways to control the symptoms or get rid of the pain temporarily until he will be seen by the Vet tomorrow.
