Gentamicin is an antibiotic used to treat various bacterial infections. It belongs to a class of drugs called aminoglycosides and works by inhibiting bacterial protein synthesis, effectively stopping the growth of bacteria. It is commonly used for serious infections caused by gram-negative bacteria and is often administered intravenously or intramuscularly. This medication is typically prescribed for infections in the bloodstream, respiratory tract, or urinary system. While gentamicin is effective, it can have side effects, including potential damage to the kidneys and hearing. Therefore, doctors monitor patients closely during treatment to ensure safety and effectiveness.
