Aminoglycoside antibiotics are used to treat serious bacterial infections, including respiratory infections, urinary tract infections, and sepsis. They also have other uses, such as treating certain types of eye infections and skin infections. These antibiotics work by stopping bacteria from making proteins, which kills the bacteria. Aminoglycosides come in different forms, and the form you choose can depend on the type of infection you have. For example, eye ointments, such as gentamicin (Gentak), are used for eye infections. Inhalation solutions, such as tobramycin (Tobi) and amikacin (Arikayce) helps treat respiratory infections. You can discuss with your prescriber to determine the best form and medication for your condition.
