- CONDITION CENTERS
Antibiotics are the drugs your doctor prescribes to treat infections caused by bacteria. Since the 1940s, they have been "the first line of defense" in treating bacterial infections. Yet, the Centers for Disease Control and Prevention (CDC) estimates that more than half of all antibiotics prescribed are not necessary.
Antibiotics are not effective against viruses and therefore should not be used to treat them. Common examples of infections caused by viruses include colds and flu.
Overuse and inappropriate use of antibiotics can make them not work when you need them, because bacteria develop resistance to them. This resistance causes the bacteria to thrive and potentially cause more harm.
What Is Antibiotic Resistance?
The development of antibiotic resistance is one of the most challenging problems in health care today. It occurs when the bacteria change in a way that reduces or stops the effectiveness of antibiotics. When this occurs, the bacteria can survive and continue to grow and strengthen.
If you take antibiotics and really do not need them, they may lose their strength and ability to effectively treat the bacteria. The most important way to reduce or prevent antibiotic resistance is by educating yourself about the proper use of antibiotics.
Steps to Reduce Antibiotic Resistance
When to Take (or Not to Take) Antibiotics
Knowing when you may need an antibiotic depends on the kind of infection you have.
The first step is to consult your physician to determine whether your infection is bacterial or viral. Always consult your doctor if you suspect that you have an infection of any kind.
Colds and Flu
As stated above, viruses cause these diseases. Antibiotic therapy will not cure them. Talk to your health care provider about the many over-the-counter medications available to treat the symptoms of colds and flu.
Remember to inform your doctor or pharmacist about all the medications you are currently taking so as to avoid harmful drug interactions.
Viruses typically cause sore throats, but bacteria, such as in strep throat, can cause some. Your physician may do a culture and a sensitivity test before prescribing antibiotic therapy.
Both viruses and bacteria can cause these infections. If you have a runny nose with yellow or green mucus, you may need an antibiotic, so consult your physician.
These infections do not always require antibiotic treatment, because both viruses and bacteria can cause them.
Coughs and Bronchitis
Viruses almost always cause these conditions. However, if you have had a medical problem with your lungs before, bacteria may be involved, and an antibiotic may be prescribed. Consult your doctor about any prolonged coughs, especially coughs with phlegm.
Proper Use of Antibiotics
When an antibiotic is prescribed for you, you should take the following steps:
Antibiotics can be very powerful in treating bacterial infections when they are used properly. To maintain their effectiveness, they should be used only when necessary.
The best way to combat infections is to educate yourself and those around you on the proper way to treat infections without causing harm or making things worse.
