Questions about antibiotics for an ear infection (from my girlfriend)

I'm currently on antibiotics for ear infection. 1g Heracillin x 3 for 7 days and Cetraxal comp ear drops also for 7 days. As far as I understand, the drops has fluocinolon, wich is usually not so good.

What can I do to best aid my body during this treatment?
My diet is pretty much grassfed beef, tallow, lard, White Rice, onions, butternut squash, pear.

I have access to Infrared sauna, Epsom foot baths, Vielight 655 low level laser therapy,
a mat for grounding/earthing, Saccaromyces boulardii, Mega Spore biotics, several binders, Samento etc.

Is it just as bad taking it as ear drops as orally?
