    Parenteral third-generation cephalosporin
    Extremely active against Pseudomonas aeruginosa; used for lower respiratory tract infections, skin and soft-tissue infections, UTIs, bone and joint infections, and meningitis
    Limited use for empiric monotherapy for neutropenic fever due to emergence of resistant pathogens and poor gram-positive activity

    Indicated for the treatment of bone and joint infections, including osteomyelitis.

    For the treatment of lower respiratory tract infections (LRTIs), including pneumonia, community-acquired pneumonia (CAP), and nosocomial pneumonia.
    For the treatment of urinary tract infection (UTI).

    For the treatment of central nervous system infections, including meningitis.
    For the treatment of skin and skin structure infections, including diabetic foot ulcer.
    For the treatment of intraabdominal infections, including peritonitis, appendicitis, intraabdominal abscess, and peritoneal dialysis-related peritonitis.

    High and prolonged serum ceftazidime concentrations can occur from usual dosages in patients with transient or persistent reduction of urinary output because of renal insufficiency; elevated levels of the drug in these patients can lead to, seizures, nonconvulsive status epilepticus (NCSE), encephalopathy, coma, asterixis, neuromuscular excitability, and myoclonus reported in patients treated with ceftazidime; adjust dosing based on creatinine clearance in patients with renal impairment

    Elevated international normalized ratio (INR) has reported in patients with nutritional deficiency, prolonged treatment, or renal or hepatic disease

    Use with caution in patients with history of seizure disorder (especially in renal impairment, where drug levels may increase significantly)

    Modify dose in renal impairment

    Use with caution in patients with history of penicillin allergy

    Prescribing the drug in the absence of proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria
