. . . I buy all my antibiotic ear drops during my twice a year Mexico trip, as the cash price is less than what my co-pay is in the US, and the Mexican version has a topical pain killer that the US version doesn't.
I went to a walk-in clinic here in the US--a chain affiliated with a local hospital--after returning from Mexico with an ear infection. The nurse practitioner there prescribed some antibiotic drops--neomycin/polymyxin with hydrocortisone (I'm reading off the bottle I saved). The visit was something like $100. My ear infection not only didn't improve but it worsened, so I went to an ENT. The ENT told me the docs-in-a-box places always prescribe those kind of ear drops and they are not what I need, so he prescribed some other antibiotic drops. I don't know what the ENT charged; probably at least another $100. My health insurance is a high-deductible/HSA plan, so it all came out of my own pocket in the end. The infection resolved with the drops. However, my hearing in one ear has never been quite the same.
My takeaways from this experience are that quality medical treatment isn't a given even in the US, and I would not trust anyone less than a specialist to treat an ear infection, let alone self-medicate using something I bought over the counter in Mexico.
