Yes, it is a valid concern, antibiotic resistance is a growing problem. What happens is that a few bacteria will usually survive a course of antibiotics. These bacteria can mutate and create a strain of resistant bacteria. Bacteria can also share their genetic information with other bacteria. They can pass on the ability to be resistant not only by multiplying, but by sharing information.

Still, most bacterial infections will respond to amoxicillin or another first-line antibiotic. Those that don't can still be taken care of with stronger antibiotics, but then the bacteria have an opportunity to become resistant to the stronger antibiotics.

If you or your child is prescribed an antibiotic, always finish the bottle. Don't stop taking the drug when you feel better. You need to take care of any stubborn bacteria still hanging on. Never use leftover antibiotics. Using leftover antibiotics actually helps bacteria become resistant. Don't request an antibiotic if your phycisian thinks it's not needed. And when your physician does prescribe one, ask what you're getting and why. Don't skip doses. To most efficiently kill bacteria, the level of antibiotic in the body should be constant, missing doses causes the blood level to drop. Following these guidelines will help you to use antibiotics effectively and prevent resistance.
