This is a good introduction to these kinds of drugs. I had always thought antibiotic drugs completely killed off bacteria, not just limited their growth.
One story I will share is that I lived in Asia for several years. They would prescribe antibiotic drugs for sicknesses, just as doctors in the United States do. The only odd difference I noticed is that doctors over there would sometimes prescribe antibiotics for only a few days when the same medications here would be prescribed for anywhere from ten days to two weeks.
I never understood that because I was told that the body would develop resistance to the medication if you took your medication that way.
Anyway, I’m not a doctor - it was just a pattern I noticed.
