Known hypersensitivity to cephalosporins.
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.
Severe renal impairment; history of allergy to penicillin; pregnancy, lactation. Lactation: enters breast milk; use with caution

Pregnancy No adequate and well-controlled studies in pregnant women Because animal reproduction studies are not always predictive of human response, cefaclor should be used during pregnancy only if necessary Lactation Effect on nursing infants is unknown; exercise caution when cefaclor is administered to a nursing woman Extended-release tablets No studies in lactating women performed; small amounts of cefaclor (?0.21 mcg/mL) detected in human milk following administration (single 500-mg dose of cefaclor extended-release tablets)
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.
