A doctor prescribes antibiotics for the treatment of a bacterial infection. It is not effective against viruses.
If you have an infection, it is important to know whether it is bacterial or viral.
Viruses cause most upper respiratory tract infections, such as the common cold and flu. Antibiotics do not work against these viruses.
If people overuse antibiotics or use them incorrectly, there is a risk that the bacteria will become resistant. This means that the antibiotic becomes less effective against that type of bacterium, as the bacterium has been able to improve its defenses.
A doctor can prescribe a broad-spectrum antibiotic to treat a wide range of infections. A narrow-spectrum antibiotic is only effective against a few types of bacteria. Some antibiotics attack aerobic bacteria, while others work against anaerobic bacteria. Aerobic bacteria need oxygen and anaerobic bacteria do not.
In some cases, antibiotics may be given to prevent rather than treat an infection, as might be the case before surgery. This is called 'prophylactic' use of antibiotics. People commonly use these antibiotics before bowel and orthopedic surgery.
