The various types of antibiotics work either by preventing an infection from growing or by destroying an existing infection. Antibiotics are produced either from a mold or a fungus or are produced synthetically. Aminoglycosides work by interfering with the protein formation of bacteria. Aminoglycosides include gentamicin, amikacin, and tobramycin .
Side effects can include damage to the nerves of hearing and balance, as well as kidney injury.
Macrolide antibiotics interfere with the protein formation of bacteria during multiplication. Erythromycin is a macrolide. Side effects include gastrointestinal discomfort. Penicillin G and V are widely used for streptococcal and other bacterial infections. Hypersensitivity reactions, for example, a fever or a rash, are fairly common side effects of penicillin use.
