Ceftazidime, sold under the brand name Fortaz among others, is a third-generation cephalosporin antibiotic useful for the treatment of a number of bacterial infections.[1][5] Specifically it is used for joint infections, meningitis, pneumonia, sepsis, urinary tract infections, malignant otitis externa, Pseudomonas aeruginosa infection, and vibrio infection.[1] It is given by injection into a vein, muscle, or eye.[1][6]

Common side effects include nausea, allergic reactions, and pain at the site of injection.[1] Other side effects may include Clostridium difficile diarrhea.[1] It is not recommended in people who have had previous anaphylaxis to a penicillin.[1] Its use is relatively safe during pregnancy and breastfeeding.[7] It is in the third-generation cephalosporin family of medications and works by interfering with the bacteria's cell wall.[1]

Ceftazidime was patented in 1978 and came into commercial use in 1984.[8] It is on the World Health Organization's List of Essential Medicines.[9] Ceftazidime is available as a generic medication.[1]
