What does the avibactam and ceftazidime label say about other medicines?

The avibactam and ceftazidime label names 3 other medicines in its interaction, contraindication or warning sections. The sentences are the labels' own; a label lists what its studies and reports found, not every interaction.

Medicine namedSectionWhat the label says
Meropenemwarnings and precautionsAVYCAZ + Metronidazole % (n/N); Meropenem % (n/N)
Metronidazolewarnings and precautionsThe reduction in clinical cure rates was more marked in patients treated with AVYCAZ plus metronidazole compared to meropenem-treated patients.
Probeneciddrug interactionsAs a potent OAT inhibitor, probenecid inhibits OAT uptake of avibactam by 56% to 70% in vitro and, therefore, has the potential to decrease the elimination of avibactam when co-administered.
