Antibiotic Resistance
When bacteria are repeatedly exposed to the same antibiotics, after a while the antibiotics can't fight them anymore. Antibiotics kill many bacteria, but they don't usually kill all of them. The ones that are left after you finish taking the antibiotic are strong enough to resist the antibiotic in the future. Antibiotic resistance is becoming a common problem in many parts of the United States.
Antibiotics Questions and Answers
Antibiotics are strong medicines that can stop some infections and save lives. But antibiotics can cause more harm than good when they aren’t used the right way. You can protect yourself and your family by knowing when you should use antibiotics and when you shouldn’t.
Using antibiotics sensibly
Frequent and inappropriate antibiotic use leads to the development of antibiotic-resistant bacteria. When bacteria outsmart standard antibiotics, you need stronger and more costly medications to treat infections. Because bacteria mutate much more quickly than researchers can develop new antibiotics, the possibility exists that one day soon highly lethal strains of resistant bacteria will evolve — and there won't be effective drugs to kill them.
The Problem of Antimicrobial Resistance
Since antibiotics and other antimicrobial drugs first became widely used in the World War II era, they have saved countless lives and blunted serious complications of many feared diseases and infections. The success of antimicrobials against disease-causing microbes is among modern medicine’s great achievements. After more than 50 years of widespread use, however, many antimicrobials are not as effective as they used to be.
Questions About Antibiotic Resistance
Bacteria are single-celled organisms usually found all over the inside and outside of our bodies, except in the blood and spinal fluid. Many bacteria are not harmful. In fact, some are actually beneficial. However, disease-causing bacteria trigger illnesses, such as strep throat and some ear infections. Viruses are even smaller than bacteria. A virus cannot survive outside the body's cells. It causes illnesses by invading healthy cells and reproducing.
Avoid Oral Antibiotics for 'Swimmer's Ear'
Antiseptic or antibiotic ear drops should be front-line treatment for swimmer's ear, and doctors should use restraint in using oral antibiotics for the common condition.
