Interactions
May enhance the anticoagulant effect of vit K antagonists (e.g. warfarin). May diminish the therapeutic effect of Na picosulfate, BCG and typhoid vaccine. May decrease the protein binding of fosphenytoin and phenytoin. Probenecid may decrease renal tubular secretion of cefazolin, resulting in increased and prolonged blood levels. May increase the nephrotoxic effects of aminoglycosides.

Diarrhoea, oral candidiasis, vomiting, nausea, stomach cramps, anorexia; eosinophilia, itching, drug fever, skin rash, Stevens-Johnson syndrome; neutropenia, leucopenia, thrombocytopenia, thrombocythemia; transient elevation in SGOT, SGPT and alkaline phosphatase levels; hepatitis; increased BUN and creatinine levels, renal failure; phlebitis, induration; genital and anal pruritus (e.g. vulvar pruritus, genital moniliasis, vaginitis).
Potentially Fatal: Anaphylaxis, pseudomembranous colitis.
Mechanism of Action
Cefazolin binds to 1 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.
