Kanamycin — Uses, Dosage, Side Effects & Safety

Drug class: Aminoglycoside antibiotic

Overview

Kanamycin is an antibiotic used to treat serious bacterial infections, especially those caused by bacteria that are resistant to other antibiotics. It is most commonly used for infections such as tuberculosis (TB), urinary tract infections, and certain hospital-acquired infections. Kanamycin works by stopping the growth of bacteria. It does this by interfering with the bacteria's ability to make proteins, which are essential for their survival. This medication is usually given by injection in a hospital or clinical setting. Key points to know: Kanamycin is reserved for serious infections when other antibiotics cannot be used. It can cause side effects, especially to the ears and kidneys, so close monitoring is needed during treatment.
