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, and urinary system. While Gentamicin can be very effective, it may also cause side effects, including kidney damage and hearing loss, especially with prolonged use or high doses. Regular monitoring is essential during treatment.
