General

The most common side effects reported were Coombs direct test positive, nausea, diarrhea, and vomiting.[Ref]

Hematologic

Very common (10% or more): Coombs direct test positive, direct antiglobulin test (DAGT or Coombs test) seroconversion, seroconversion from negative to positive direct Coombs test result

Common (1% to 10%): Thrombocytosis, thrombocytopenia

Uncommon (0.1% to 1%): Leukopenia

Ceftazidime:

-Common (1% to 10%): Eosinophilia

-Uncommon (0.1% to 1%): Neutropenia, lymphocytosis

-Frequency not reported: Agranulocytosis, hemolytic anemia, prolonged prothrombin time[Ref]

DAGT seroconversion in patients using this drug was very common in clinical studies; the estimated range of seroconversion across phase 3 trials was 3.2% to 20.8% in patients with negative Coombs test at baseline and at least 1 follow-up test.

In the phase 3 trials, seroconversion from negative to positive direct Coombs test result among patients with initial negative Coombs test and at least 1 follow-up test was reported in 12.9% (complicated intraabdominal infection [cIAI]), 3% (complicated urinary tract infection [cUTI]), and 21.4% (hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia [HABP/VABP]) of patients using this drug and 3% (cIAI), 0.9% (cUTI), and 7% (HABP/VABP) of patients using a carbapenem comparator. No side effects indicating hemolytic anemia were reported in any treatment group.[Ref]

Gastrointestinal

Common (1% to 10%): Diarrhea, nausea, vomiting, abdominal pain, constipation, upper abdominal pain

Uncommon (0.1% to 1%): Clostridium difficile colitis, pseudomembranous colitis

Frequency not reported: Clostridium difficile-associated diarrhea[Ref]

Other

Common (1% to 10%): Increased blood alkaline phosphatase, pyrexia, candidiasis (including vulvovaginal and oral), death/increased mortality

Frequency not reported: Decreased clinical response, accidental overdose

Ceftazidime:

-Common (1% to 10%): Increased blood lactate dehydrogenase[Ref]

In a phase 3 cIAI trial, death occurred in 13 of 529 patients using this drug plus metronidazole and 8 of 529 patients using meropenem. In a subgroup of patients with baseline CrCl 30 to 50 mL/min, death occurred in 8 of 41 patients using this drug plus metronidazole and 3 of 43 patients using meropenem; patients using this drug received a 33% lower daily dose than is currently recommended for this patient population. In patients with baseline CrCl greater than 50 mL/min, death occurred in 5 of 485 patients using this drug plus metronidazole and 5 of 484 patients using meropenem. Cause of death varied; contributing factors included progression of underlying infection, baseline pathogens isolated that were unlikely to respond to study drug, and delayed surgical intervention.

In 2 studies in patients with cIAI, the most common diagnosis (about 42%) was appendiceal perforation or peri-appendiceal abscess. About 87% of patients had APACHE II scores up to 10 and 4% had bacteremia at baseline. Death occurred in 18 of 857 patients who used this drug plus metronidazole and in 12 of 863 patients who used meropenem. In a subgroup with baseline CrCl 30 to 50 mL/min, death occurred in 9 of 54 patients who used this drug plus metronidazole and 4 of 59 patients who used meropenem; these patients used a lower dose of this drug than is currently recommended for patients with CrCl 30 to 50 mL/min.
