Antibiotics are routinely used for the treatment of infections in all disciplines. Antibiotics, on the other hand, have immunomodulatory and anti-inflammatory characteristics and can be used to treat a variety of noninfectious dermatoses. Examples include the use of tetracyclines to treat rosacea or erythromycin to reduce skin inflammation related to acne. Studies have shown that there is a correlation between the use of antibiotics and increased resistance to human pathogens, so it is important to use these medications properly. The most effective way of doing this is by limiting the use of antibiotics when they are not needed. Some common signs of an infection being caused by bacteria rather than a virus include the presence of pus and a high temperature. If you suspect that you have an infection, see your doctor immediately so that proper treatment can be started.
