Adverse Events

Special Warnings and Precautions for Use

Drug-drug interactions

*In four Phase III clinical trials, the adverse event profile of ZAVICEFTA was similar to that seen with either best available therapy, doripenem or meropenem1–4

  • Overall rates of any AE were low in the ZAVICEFTA and comparator arms1–4
  • Rates of all other AE categories were low and balanced across treatment arms1–4
  • Most common (>5%) AEs for ZAVICEFTA were positive direct Coombs test, nausea and diarrhoea5*
  • Nausea and diarrhoea were usually mild or moderate in intensity1-5
  • Low potential for drug-drug interactions5

*Based on data from seven Phase II and Phase III clinical trials in 2024 adult patients treated with ZAVICEFTA.5

An overall safety profile consistent with that of ceftazidime alone1-6

*ZAVICEFTA use may cause development of a positive DAGT or Coombs test, which may interfere with the cross-matching of blood and/or may cause drug induced immune haemolytic anaemia. While DAGT seroconversion in patients receiving ZAVICEFTA was very common in clinical studies (the estimated range of seroconversion across Phase III studies was 3.2% to 20.8% in patients with a negative Coombs test at baseline and at least one follow-up test), there was no evidence of haemolysis in patients who developed a positive DAGT on treatment. However, the possibility that haemolytic anaemia could occur in association with ZAVICEFTA treatment cannot be ruled out. Patients experiencing anaemia during or after treatment with ZAVICEFTA should be investigated for this possibility.5
