Ceftriaxone injection is a broad-spectrum antibiotic widely used to treat bacterial infections, including respiratory, urinary tract, skin, and bloodstream infections. As a third-generation cephalosporin, ceftriaxone injection is highly effective against gram-positive and gram-negative bacteria. It works by inhibiting bacterial cell wall synthesis, leading to bacterial cell death. Administered intravenously or intramuscularly, Ceftriaxone injection is commonly prescribed for pneumonia, meningitis, and gonorrhea. Its once-daily dosing enhances patient compliance. However, potential side effects include diarrhea, rash, and allergic reactions. Despite its efficacy, Ceftriaxone injection should be used cautiously to prevent antibiotic resistance and under medical supervision for optimal results.
