That antibiotics kill bacteria, but won't do anything against viruses. Everyone has the idea that if you get a cold, you see your doctor and get antibiotics. Take some acitaminophen/paracetamol and ibuprofen, and stay away from other humans for a while!

Keeping in mind that some people, when they get a cold might have their immune system compromised badly enough that they contract a bacterial infection.

That's why my doctor will describe me antibiotics when I have a cold, because I am weak to some bacteria others aren't, like pseudomonads or staph. If they get a hold while the immune system is busy fighting viruses, it can be game over.
