One disadvantage of the use of antibiotics to fight bacterial diseases?

If the person using the antibiotic stops taking them (even after the disease seems to be gone), the remaining bacteria will become resistant to the antibiotic, so when the disease comes back (caused by the multiplication of the bacteria), antibiotics will not work. This is important because if you are taking antibiotics that your doctor prescribed, do not stop taking it until you have finished the bottle. Don't think you're doing yourself a favor by saving half the bottle for later, when you get another infection. Save yourself the pain and finish the bottle so all the bacteria can be gone.
