FDA has not yet classified the drug into a specified pregnancy category.
Mode of Action
Cefaclor binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death. It has bactericidal activity against gm-ve bacteria including E. coli, S. pneumoniae, N. gonorrhoea, P. mirabilis and H. influenzae.
Interaction
May enhance the nephrotoxic effect of aminoglycosides. May diminish the therapeutic effect of BCG, typhoid vaccine and Na picosulfate. Concomitant use w/ warfarin may increase prothrombin time. Probenecid inhibits renal excretion of cefaclor.
Pregnancy Category Note

Because animal reproduction studies are not always predictive of human response, cefaclor should be used during pregnancy only if necessary
