Antibiotics are among the most commonly used drugs; however, their effectiveness is consistently decreasing due to the increasing global spread of antimicrobial resistance. The evolvement of the antimicrobial resistance crisis depends on the scope and way antibiotics are used, making careful follow-up of their use a public health priority. Unnecessary use of broad-spectrum antimicrobials is a major contributor to the emergence and spread of antimicrobial resistance .
