What is an antibiotic?

An antibiotic is a chemical that assists your immune system in getting rid of bacteria. Antibiotics are not effective against viruses. Most of the infections we have are viral, so antibiotics are not helpful. So they are worthless against the common cold. Some antibiotics have direct killing power against bacteria, and other antibiotics render the bacteria more susceptible to our own immune system. Often the bacteria learn how to avoid the antibiotic, so antibiotic resistance develops. Therefore, it is important not to overuse antibiotics.
