Health Canada recently conducted a safety review and found there may be a link between the use of bacitracin for injection products and the risk of nephrotoxicity and hypersensitivity, including allergic contact dermatitis and/or anaphylaxis. Cases of nephrotoxicity and serious hypersensitivity, including allergic contact dermatitis and/or anaphylaxis, have also been reported when these products are used outside of their authorized indications. Health Canada is working with the manufacturers to update the Canadian Product Monographs for all bacitracin for injection products to further strengthen the information about nephrotoxicity and to include information about anaphylactic reactions.
