An antibiotic is a chemical substance that inhbits the growth or kills a microorganism. However, microorganisms are always evolving quickly and have a high degree of adaptation and can get used to the antibiotic after some time. This means the given antibiotic will have no effect in the pathogen after some time. Increased quantity of antibiotics can also kill the good bacteria and reduce the important vitamins in the body.
