Antibiotic resistance is one of the most urgent threats to the public’s health. Antibiotic resistance occurs when bacteria develop the ability to defeat the drugs designed to kill them. Each year in the United States, at least 2 million people get infected with antibiotic-resistant bacteria, and at least 23,000 people die as a result.
Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance. About 30 percent of antibiotics, or 47 million prescriptions, are prescribed unnecessarily in doctors’ offices and emergency departments in the United States, which makes improving antibiotic prescribing and use a national priority.
Helping healthcare professionals improve the way they prescribe antibiotics, and improving the way we take antibiotics, helps keep us healthy now, helps fight antibiotic resistance, and ensures that these life-saving drugs will be available for future generations.
When Antibiotics Are Needed
Antibiotics are only needed for treating certain infections caused by bacteria. We rely on antibiotics to treat serious infections, such as pneumonia, and life-threatening conditions including sepsis, the body’s extreme response to an infection. Effective antibiotics are also needed for people who are at high risk for developing infections. Some of those at high risk for infections include patients undergoing surgery, patients with end-stage kidney disease, or patients receiving cancer therapy (chemotherapy).
When Antibiotics Aren’t Needed
Antibiotics won’t help for some common bacterial infections including most cases of bronchitis, many sinus infections, and some ear infections. An antibiotic will not make you feel better if you have a virus. Antibiotics do not work on viral infections, such as colds, flu, or runny noses, even if the mucus is thick, yellow or green.
Antibiotics save lives, and when a patient needs antibiotics, the benefits outweigh the risk of side effects. When antibiotics aren’t needed, they won’t help you, and the side effects could still hurt you. Common side effects of antibiotics can include:
• diarrhea, and
• yeast infections.
More serious side effects include Clostridium difficile infection (also called C. difficile or C. diff), which causes diarrhea that can lead to severe colon damage and death. People can also have severe and life-threatening allergic reactions.
What You Can Do To Feel Better
Talk with your healthcare professional about the best treatment for your or your loved one’s illness. If you need antibiotics, take them exactly as prescribed. Talk with your healthcare professional if you have any questions about your antibiotics, or if you develop any side effects especially diarrhea, since that could be a C. difficile infection, which needs to be treated immediately.
Respiratory viruses usually go away in a week or two without treatment. Ask your healthcare professional about the best way to feel better while your body fights off the virus. To stay healthy and keep others healthy:
• Clean your hands.
• Cover coughs.
• Stay home when sick.
• Get recommended vaccines, for the flu, for example.
