Ceftriaxone is used to treat bacterial infections including community-acquired pneumonia, meningitis, gonorrhea, and infections of the bones, joints, skin, and urinary tract. It may also be used for surgical prophylaxis and in severe infections requiring hospitalization.

Ceftriaxone works by inhibiting the synthesis of the bacterial cell wall, which is essential for bacterial survival. It binds to penicillin-binding proteins and disrupts cell wall construction, leading to bacterial death.

Ceftriaxone is administered by intramuscular or intravenous injection. It may cause side effects such as diarrhea, rash, or injection site reactions. Caution is needed in patients with penicillin allergy, kidney impairment, or those on calcium-containing products. Always complete the full course as prescribed by your healthcare provider.
