Colds are usually caused by a virus. Antibiotics treat illnesses caused by bacteria. If you go see your doctor when you are sick, your doctor will determine if you are sick because of a virus or bacteria.

If you do have a cold, then your doctor will not prescribe you an antibiotic to treat it—even though you want relief—because it will not treat your cold.   

In addition, it can be harmful to take antibiotics when you don’t need them. They may not work when you do need them, because your body has gotten used to them.

Your doctor will give you information on how to treat your cold.

Remember: Any medicine can cause harmful side effects. Whether it is an antibiotic or an over-the-counter medicine, follow the instructions.
