There are different kinds of germs that can make people sick. Some illnesses are caused by bacteria and some are caused by viruses. Antibiotics, like penicillin, fight infections due to bacteria that can cause some serious illnesses. But, these medicines can cause life threatening allergies and side effects like rashes, diarrhea, tendon damage and yeast infections. If your infection is due to a virus, antibiotics will not help you to feel better and you could still get these bad side effects. Bacteria can become resistant to antibiotics. This means that antibiotics might not work when you, and your family, really need them in the future. Because of this, it is important that you only use an antibiotic when it is necessary, and take it exactly as the doctor tells you.
