Ceftriaxone injection is a broad-spectrum cephalosporin antibiotic effective against various bacterial infections. It treats conditions like pneumonia, meningitis, urinary tract infections, gonorrhea, and septicemia caused by susceptible bacteria. The ceftriaxone injection is also used for skin and soft tissue infections, bone and joint infections, and intra-abdominal infections, such as peritonitis. It’s effective against Streptococcus pneumoniae, Neisseria meningitidis, Escherichia coli, and Haemophilus influenzae, among others. Administered intravenously or intramuscularly, Ceftriaxone injection is often reserved for serious infections or when oral antibiotics are ineffective. Always consult a healthcare provider for proper diagnosis and treatment.
