Description: Gentamicin is an antibiotic used to treat several types of bacterial infections. This may include bone infections, endocarditis, pelvic inflammatory disease, meningitis, pneumonia, urinary tract infections, and sepsis among others. It is not effective for gonorrhea or chlamydia infections. Gentamicin is a complex of three different closely related aminoglycoside sulfates, Gentamicins C1, C2, and C1(subA), obtained from Micromonospora purpurea and related species. They are broad-spectrum antibiotics, but may cause ear and kidney damage. They act to inhibit protein synthesis.

Additional Information

It can be given intravenously, by injection into a muscle, or topically. Topical formulations may be used in burns or for infections of the outside of the eye. In the developed world it is often only used for two days until bacterial cultures determine what antibiotics the infection is sensitive to. The dose required should be monitored by blood testing.
