But in the US at least antibiotics require a prescription from doctors. So you need the doctors to play along, too, and in my own experience I’ve never received antibiotics unnecessarily
I could speculate on how else it happens, but the important part is that it does happen, and e.g. the Mayo clinic says:
> According to the Centers for Disease Control and Prevention, about one-third of antibiotic use in people is not needed nor appropriate.

Major cultural difference to the point where Brazilians feel like American doctors aren’t even treating them.
