If you have an infection, your doctor prescribes you antibiotics. You go to the pharmacy to pick them up, and the pharmacist gives you an unenthusiastic breakdown of how to take them, what not to take when you’re on them, and what they’ll do—as if she’s said this a thousand times (she has). Everyone is so casual about antibiotics, that it makes you feel at ease about taking them. And, for the most part, you should feel that way since in many cases, your health depends heavily on them. But any time we take something that greatly alters what’s happening inside of our bodies, from birth control pills to laxatives, we should know a little bit about them. Antibiotics are no different. Here are things you should know about antibiotics that your doctor probably won’t tell you.

Here’s who takes them the most

Animals actually take the most antibiotics, followed by children, then the elderly.

Antibiotic resistance is contagious

If an antibiotic does not succeed in killing all infectious bacteria, the ones that survive may multiply, and actually manifest on the surface of one’s skin. This is how antibiotic resistance can jump from one person to another.

They can’t cure the common cold or flu

Antibiotics cannot kill the viruses that cause colds and flus—antibiotics only attack bacterial infections. Taking antibiotics for the common cold or flu will only strengthen resistant bacteria in your body, without helping you get better.

You may feel better, but the antibiotic isn’t finished

If you have a bacterial infection, you will likely begin to feel much better before you’ve finished taking the prescribed dosage of the antibiotic. You should not, however, stop taking it because the bacteria is likely still alive in your body.

For viral infections, stop as soon as possible

With a bacterial infection, you should take your entire prescribed dosage of antibiotic. However, if you’re suffering a viral infection and are on antibiotics, you can and should stop taking them when you begin to feel better since antibiotics should not necessarily be used in these types of infections.

Patients pressure their doctors

It’s not entirely the medical industry’s fault for the over-prescription and wrongful-prescription of antibiotics. Patients often demand them of their doctors, insisting they need them immediately to feel better. Never pressure your doctor to prescribe you antibiotics; if he doesn’t think you need them, you don’t.
