There's an effort by the Centers for Disease Control and Prevention (CDC) to help make sure that we use antibiotics wisely. In the U.S. 1 in 5 of children visits to health care practitioners result in a prescription of antibiotics. This amounts to over 50 million prescriptions annually! Of which 10 million are for respiratory illnesses that antibiotics aren't helpful for.

Antibiotics are of course very important and life saving when they are needed, however, their use does not come without risks including the killing off of natural bacteria that grow in our bodies and that we rely upon for forging a healthy immune system to fight off disease and infections. Antibiotic resistance is another concern of indiscriminate prescribing.

Here's a helpful quick quiz published in Harvard Health Publications to help families make informed decisions about antibiotic use.

Question: (True or false) Any time the doctor says your child has an ear infection, you should leave the office with a prescription for antibiotics.

Answer: False. Turns out that most ear infections get better without antibiotics. In some circumstances, such as in young infants, severe infections, or children with immune system problems, antibiotics are necessary. But for most healthy children, all that is really needed is some acetaminophen or ibuprofen for pain, some time, and some TLC.

Question: Which of the following set of symptoms means your child has sinusitis?

A. A cough for a week, with fever at the beginning and not since

B. Green nasal discharge and cough for four days, fever to 101

C. Both of the above

D. None of the above

Answer: D. The common cold, caused by a virus, can give you cough, fever, and green nasal discharge — and antibiotics are not only unnecessary, they won’t do a thing. Antibiotics should only be considered if:

There is nasal congestion and cough, preferably with fever, that has lasted for 10 days or more (it still may be a cold, your doctor needs to examine and be sure)
There is new fever, congestion, and cough after a cold seemed to be getting better
There is high fever (103 F or more) and severe congestion and cough for three days

Question: Your child has a bad sore throat and fever. You take your child to the doctor, who says that the throat is very red and has pus, but doesn’t find anything else that worries her. What should happen?

A. You should get antibiotics, because pus means there must be a bacteria

B. You should get a strep test and antibiotics

C. You should get a strep test, but no antibiotics unless the rapid strep test or culture comes back positive.

Answer: C. Turns out that pus doesn’t necessarily mean there are bacteria. Some of the nastiest throat infections are caused by viruses — which, again, antibiotics don’t treat.

Question: (True or False) Since sometimes colds can lead to ear infections or sinusitis or pneumonia, it’s a good idea to take an antibiotic to prevent that from happening.

Answer: False. While it’s really understandable to want to “be on the safe side” and ward off a bacterial infection, most colds don’t lead to bacterial infections — and if you are in touch with your doctor, you should be able to pick up the signs of anything that needs to be treated by antibiotics.
