Cefmetazole Side Effects

Applies to cefmetazole: injectable powder for injection, intravenous solution.


Cefmetazole has been generally well tolerated. In large studies only 2% to 4% of patients reported side effects.[Ref]


Rare cases of pseudomembranous colitis have been reported.[Ref]

Gastrointestinal side effects have included nausea, vomiting, diarrhea, and abdominal pain which were reported in up to 4% of patients.[Ref]


Hepatic side effects have included rare reports of mild increases in liver function tests.[Ref]

Rare cases of cholestatic jaundice have been reported.

Mild increases in liver function tests may be important in patients with liver disease[Ref]


Hypersensitivity side effects have included rare reports of a rash (less than 1% of patients).[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]


Although mild, insignificant hypoprothrombinemia has been reported. However, no clinically significant hemorrhage or increased bleeding times have been documented.[Ref]

Hematologic side effects have included very rare reports of thrombocytopenia, leukopenia, agranulocytosis, anemia, and eosinophilia.[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 difficult.[Ref]


The use of glucose oxidase methods (e.g.,Testape, Keto-Diastix, and Chemstrip) to measure urine glucose is recommended during therapy.[Ref]

Other side effects have included a possible overestimation of urine glucose by the copper reduction method of urine dipstick analysis (Clinitest).[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]
