Take the Antibiotics Quiz
Antibiotics have been called "wonder drugs" because of their ability to treat bacterial infections that were once deadly. Antibiotics have saved countless lives since they were first introduced 60 years ago. But overuse of these drugs has allowed certain bacteria to become resistant to them. Learn more about this important issue by taking this quiz, based on information from the CDC and the Alliance for the Prudent Use of Antibiotics (APUA).
1. Antibiotics kill both viruses and bacteria that cause illness.
You didn't answer this question.

The correct answer is
Antibiotics kill only bacteria. They do not have any effect on viruses. Sometimes, when you take an antibiotic, the bacteria may be resistant or become resistant, the CDC says. Resistant bacteria do not respond to the antibiotic and continue to cause infection. You should take antibiotics only when necessary. Each time you take an antibiotic unnecessarily (for a viral infection, for example) or improperly (taking a partial dose, for example), you increase your chance of developing drug-resistant bacteria. Because of resistant bacteria, diseases such as tuberculosis, pneumonia, and meningitis that once were easy to treat with antibiotics are now becoming much more difficult to treat. Once a particular type of bacteria has developed resistance to a drug, it can pass on that resistance to other types of bacteria.
2. Antibiotics will help you recover from a cold or the flu.

The correct answer is
Viruses cause all colds and flu, as well as most coughs and most sore throats. Antibiotics cannot kill viruses. Taking an antibiotic for a cold or the flu will not affect the course of your illness and may contribute to bacterial resistance. (In children, this is especially critical, because children often play in close contact and can easily pass resistant bacteria onto others, spreading the problem.) Your doctor will probably prescribe an antibiotic if you have an ear infection, a sinus infection, strep throat, or a urinary tract infection. Many of these infections are caused by bacteria.
3. Many antibiotics are designed to work against specific bacteria.

You answered
The correct answer is
These antibiotics are called "narrow-spectrum" antibiotics. The other major category of antibiotics is "broad-spectrum." These antibiotics are used to treat more severe infections that don't respond to the narrow-spectrum type. Unfortunately, more and more doctors have turned to the broad-spectrum antibiotics for less severe infections, a recent study says. Experts fear that overuse of these broad-spectrum antibiotics will lead to more bacterial resistance. These broad-spectrum antibiotics are more expensive than narrow-spectrum antibiotics.
4. If you are taking antibiotics, it's OK to stop taking the medicine once you start to feel better.
You didn't answer this question.
You answered
The correct answer is
It's important to take the full dose of medicine prescribed for your illness. If you stop taking the medicine before you have completed the dose, some of the bacteria that caused your illness may still be in your body. If the bacteria are exposed to only a small dose of an antibiotic or if an antibiotic is not given enough time to kill the bacteria, the bacteria will develop resistance to the antibiotic. The next time the antibiotic is given, the bacteria will not be susceptible to it. They can then multiply in number and cause your illness to recur. They can transfer their drug resistance to the next generation of bacteria.
5. Keeping extra antibiotics around is a good idea in case you need them at a future date.
You didn't answer this question.
You answered
The correct answer is
You should not take antibiotics left over from a previous illness. These antibiotics would make up only a partial dose, which would not be enough to fight off a bacterial infection, and could create bacterial resistance. More important, your current illness may not be caused by bacteria, which would make the antibiotics useless. Always check with your health care provider before taking any antibiotic.
6. Antibiotics kill not only the bad bacteria causing your illness, but also the good bacteria that inhabit your body.
You didn't answer this question.
You answered
The correct answer is
That's why taking an antibiotic can cause symptoms associated with loss of good bacteria such as diarrhea, vaginal yeast infections, oral thrush, and an inflammation of the small intestine and colon called enterocolitis. If you have any of these side effects, be sure to tell your health care provider.
7. If you believe that an antibiotic would help your illness, you should demand that your health care provider give you a prescription for one.
You didn't answer this question.
You answered
The correct answer is
Improper use of antibiotics contributes to bacterial resistance to these drugs. Half of the 100 million prescriptions written in this country each year are unnecessary because they are prescribed for the common cold and other viral infections, the CDC says. Ask your health care provider why an antibiotic was not prescribed for your illness, but don't demand one. Your health care provider is the best source of information on antibiotic use.
8. All antibiotics are safe to take during pregnancy and breast-feeding.
You didn't answer this question.
You answered
The correct answer is
Although many antibiotics are safe to take if you are pregnant or breast-feeding, some are not. Some of these drugs can affect your growing fetus. Your health care provider will make the correct choice of medication for you. Be sure to tell your health care provider if you are breast-feeding.
9. Using an antibacterial soap is a good way to keep bacteria at bay.
You didn't answer this question.
You answered
The correct answer is
Although hospitals and other medical facilities use antibacterial soaps, they follow strict guidelines for their use, according to the APUA. Some health experts are concerned that using antibacterial soaps at home can increase bacterial resistance to these soaps. Studies have not proved that these soaps work any better than ordinary soaps to eliminate bacteria.
10. Over time, people can become resistant to antibiotics.
You didn't answer this question.
You answered
The correct answer is
Although many people mistakenly believe this, it is not true. It is the bacteria themselves, not the person who harbors the bacteria, that become resistant to antibiotics.
