My 16 year old started AMOX/K Clav 875 MG twice daily for sinus infection, the Doctor also said inner ear was red with a little bit of fluid but did not have pus. He started the RX on Saturday July 5, 2014. This morning he had a little fluid leak out of his ear. He has no pain, but feels like it is blocked or that he does not hear quite as well, mostly annoying. Can we or should we use Hydrogen Peroxide to help? or because it is in the inner ear it will not be effective?
