Ceftriaxone injection is a broad-spectrum cephalosporin antibiotic used to treat various bacterial infections. Administered intramuscularly or intravenously, ceftriaxone injection is effective against conditions like pneumonia, meningitis, urinary tract infections, gonorrhea, and septicemia. It works by inhibiting bacterial cell wall synthesis, leading to bacterial death. The ceftriaxone injection is often prescribed for severe infections or when oral antibiotics are ineffective. Dosage and duration depend on the infection’s severity and patient factors. While generally safe, ceftriaxone injection may cause side effects like diarrhea, rash, or allergic reactions. It is not effective against viral infections. Always consult a healthcare professional before using ceftriaxone injection.
