This might be a bit of an unpopular opinion, but I think that using antibiotics unless you [absolutely] have to - like when you get one prescribed - is a problem if you think long-term because of a higher chance of antibiotics resistance. Using antibiotics "just in case" should be avoided.
Here's an example of E. coli developing resistance to a _strong_ antibiotic within 12 days [0].
Unfortunately, I know more than a few people who take antibiotics even when they get common cold/flu, which doesn't make sense since viruses are not bacteria and they should get vaccinated instead.
