Can Nafarin-A Be Taken For Ear Blockage And Sinusitis?

Hi, I'm having problems with my ear at the moment. I have retracted eardrum as nurse practitioner said when I had clinic appointment. Given me Augmentin for antibiotics. I am experiencing vertigo and balance is not great at the moment. Will it be possible to take nafarin a as well as my event doctor prescribed to me whenever ear feels blocked and suffer from sinusitis? Thank u
