Bacterial Infection vs. Virus: Do I Need an Antibiotic?

Bacterial Infections

Antibiotics are used to treat bacterial infections. Some surgeons prescribe antibiotics to people before or after surgery to help prevent a bacterial infection.

Antibiotics are prescribed by a doctor and you can only get them from a pharmacist at the pharmacy counter. Using antibiotics when they are not needed can cause harmful side effects and make antibiotics less powerful against some bacteria.

If your health care provider prescribes an antibiotic for you, follow his/her instructions on how and when to take it. Always finish all of the antibiotics unless your health care provider tells you otherwise.

Do not take other people’s antibiotics or old antibiotics.

Also do not share your antibiotics with anyone. They were prescribed to treat your illness, not someone else’s.

Viruses

A virus is an illness that does not involve a bacterial infection.

Antibiotics do not cure viruses.

However, your health care provider can suggest over-the-counter medications (medications that you do not have to get from the pharmacist) that may help you feel better.
