Applies to cefmetazole: injectable powder for injection, intravenous solution
Cefmetazole (the active ingredient contained in Zefazone) has been generally well tolerated. In large studies only 2% to 4% of patients reported side effects.[Ref]
Rare cases of anaphylaxis, hypersensitivity hepatitis, and Stevens-Johnson syndrome have been reported.
A case of occupational contact dermatitis due to cephalosporin allergy has been reported in a nurse who prepared cephalosporin solutions for administration to patients. The dermatitis resolved after the nurse stopped preparing the solutions.[Ref]
Hypersensitivity side effects have included rare reports of a rash (less than 1% of patients).[Ref]
Although mild, insignificant hypoprothrombinemia has been reported. However, no clinically significant hemorrhage or increased bleeding times have been documented.[Ref]
Cardiovascular side effects have included informal reports of hypotension and shock, but the type of infection and clinical conditions of the patients made implication of cefmetazole (the active ingredient contained in Zefazone) difficult.[Ref]
Other side effects have included a possible overestimation of urine glucose by the copper reduction method of urine dipstick analysis (Clinitest).[Ref]
The use of glucose oxidase methods (e.g.,Testape, Keto-Diastix, and Chemstrip) to measure urine glucose is recommended during therapy.[Ref]
Renal side effects have included reports of new or worsened renal insufficiency. These were difficult to interpret due to underlying diseases and concomitant therapy.[Ref]
