Contra Indications
Hypersensitivity to cephalosporins.
Precautions
Hypersensitivity Reactions: Cross-hypersensitivity may occur in up to 10% of patients with a history of penicillin allergy. If an allergic reaction occurs, discontinue the drug.
Clostridioides difficile-associated diarrhea (CDAD): May range from mild diarrhea to fatal colitis. Evaluate if diarrhea occurs.
Prothrombin Activity: May be associated with a fall in prothrombin activity. Prothrombin time should be monitored in patients at risk and exogenous vitamin K was administered as indicated
Pregnancy-Lactation
Pregnancy
Available data from published prospective cohort studies, case series and case reports over several decades with cephalosporin use, including cefazolin, in pregnant women have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes; drug crosses the placenta
Animal data
Animal reproduction studies with rats, mice and rabbits administered cefazolin during organogenesis at doses 1 to 3 times maximum recommended human dose (MRHD) did not demonstrate adverse developmental outcomes; in rats subcutaneously administered cefazolin prior to delivery and throughout lactation, there were no adverse effects on offspring at a dose approximately 2 times the MRHD
Lactation
Data from published literature report that cefazolin is present in human milk, but not expected to accumulate in a breastfed infant; there are no data on effects of drug on breastfed child or on milk production
Developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from drug or from the mother’s underlying condition
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.
