The basic idea about antibiotic course completion is that: Antibiotics initially kill weaker bacteria only and stopping medications early may allow leftover pathogens to multiply and form a resistance. But there is no solid evidence behind it and infectious disease experts suggested in an article published in The BMJ that everyone finish their antibiotics all the time may actually be increasing antibiotic resistance worldwide because it's the consumption of antibiotics for longer than absolutely necessary that increases the risk of resistance. Even a 1999 Lancet journal article described that: bacterial resistance rarely arises in one patient from one treatment.
Rather, it is a population-wide phenomenon in which bacteria spread from host to host, acquire all kinds of genetic traits, and may be resistant to a particular antibiotic before the bacteria even enter your body. The BMJ…
