Information for Patients

Antibiotic Resistance

Antibiotics are medicines that fight bacterial infections. Used properly, they can save lives. But there is a growing problem of antibiotic resistance. It happens when bacteria change and become able to resist the effects of an antibiotic.

Using antibiotics can lead to resistance. Each time you take antibiotics, sensitive bacteria are killed. But resistant germs may be left to grow and multiply. They can spread to other people. They can also cause infections that certain antibiotics cannot cure. Methicillin-resistant Staphylococcus aureus (MRSA) is one example. It causes infections that are resistant to several common antibiotics.

To help prevent antibiotic resistance

  • Don't use antibiotics for viruses like colds or flu. Antibiotics don't work on viruses.
  • Don't pressure your doctor to give you an antibiotic.
  • When you take antibiotics, follow the directions carefully. Finish your medicine even if you feel better. If you stop treatment too soon, some bacteria may survive and re-infect you.
  • Don't save antibiotics for later or use someone else's prescription.

Also called: Methicillin-resistant Staphylococcus aureus

MRSA stands for methicillin-resistant Staphylococcus aureus. It causes a staph infection (pronounced "staff infection") that is resistant to several common antibiotics. There are two types of infection. Hospital-associated MRSA happens to people in healthcare settings. Community-associated MRSA happens to people who have close skin-to-skin contact with others, such as athletes involved in football and wrestling.

Infection control is key to stopping MRSA in hospitals. To prevent community-associated MRSA

  • Practice good hygiene
  • Keep cuts and scrapes clean and covered with a bandage until healed
  • Avoid contact with other people's wounds or bandages
  • Avoid sharing personal items, such as towels, washcloths, razors, or clothes
  • Wash soiled sheets, towels, and clothes in hot water with bleach and dry in a hot dryer

If a wound appears to be infected, see a health care provider. Treatments may include draining the infection and antibiotics.

Also called: Bronchopneumonia

Pneumonia is an infection in one or both of the lungs. Many germs, such as bacteria, viruses, and fungi, can cause pneumonia. You can also get pneumonia by inhaling a liquid or chemical. People most at risk are older than 65 or younger than 2 years of age, or already have health problems.

Symptoms of pneumonia vary from mild to severe. See your doctor promptly if you

  • Have a high fever
  • Have shaking chills
  • Have a cough with phlegm that doesn't improve or gets worse
  • Develop shortness of breath with normal daily activities
  • Have chest pain when you breathe or cough
  • Feel suddenly worse after a cold or the flu

Your doctor will use your medical history, a physical exam, and lab tests to diagnose pneumonia. Treatment depends on what kind you have. If bacteria are the cause, antibiotics should help. If you have viral pneumonia, your doctor may prescribe an antiviral medicine to treat it.

Preventing pneumonia is always better than treating it. Vaccines are available to prevent pneumococcal pneumonia and the flu. Other preventive measures include washing your hands frequently and not smoking.
