Patient Education

Tobramycin Injection


Tobramycin injection is used to treat certain serious infections that are caused by bacteria such as meningitis (infection of the membranes that surround the brain and spinal cord) and infections of the blood, abdomen (stomach area), lungs, skin, bones, joints, and urinary tract. Tobramycin injection is in a class of medications called aminoglycoside antibiotics. It works by killing bacteria. Antibiotics such as tobramycin injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
