For Healthcare Professionals
Applies to cefotaxime: injectable powder for injection, intravenous solution
The majority of cefotaxime adverse effects are mild and transient and rarely require discontinuation of the medication.
Gastrointestinal side effects have included colitis, nausea, vomiting, and diarrhea in 1.4% of patients. Clostridium difficile associated diarrhea has been reported with almost all antibiotics, including the cephalosporins.
Clostridium difficile should be suspected in any patient who develops persistent or severe diarrhea following cephalosporin therapy.
One small study indicates that elderly patients treated with cefotaxime may be more likely than younger patients to experience Clostridium difficile colitis.
Hypersensitivity reactions, such as rash and pruritus, are relatively uncommon, but may require discontinuation of the drug.
A 75-year-old female developed toxic epidermal necrolysis (TEN) over 40% of her body surface area after receiving cefotaxime for 6 days. After cefotaxime discontinuation and some improvement, meropenem was started. The TEN immediately recurred and spread to previously unaffected areas of the skin, and the patient died. The authors recommend avoiding chemically similar drugs to the precipitating drug when treating patients with drug-induced TEN.
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.
Hypersensitivity side effects have included rash, pruritus, fever, eosinophilia, urticaria, and anaphylaxis (e.g., angioedema, bronchospasm, malaise possibly culminating in shock) in 2.4% of patients. Allergic cross-reactivity with penicillin and carbapenems may occur. Cases of Stevens-Johnson syndrome, erythema multiforme, and toxic epidermal necrolysis have been reported. Allergic reactions have been reported with cephalosporins as a class.
Other side effects have included overgrowth of nonsusceptible organisms and have resulted in superinfection. False-positive test for urinary glucose have been reported with cephalosporins as a class.
Local side effects have included injection site inflammation and phlebitis with intravenous administration and pain, induration, and tenderness following intramuscular injection in 4.3% of patients.
Nervous system side effects have included headache and encephalopathy (e.g., impairment of consciousness, abnormal movements, and convulsions) in less than 1% of patients. Some cephalosporins have been associated with seizures, particularly in renally impaired patients when the dosage was not reduced.
Administration of high doses of beta-lactams, including cefotaxime, particularly in patients with renal insufficiency may result in encephalopathy.
In one case, a 68-year-old man with moderate renal insufficiency underwent surgery for repair of an abdominal aortic aneurysm. He developed renal failure requiring hemodialysis. Cefotaxime was administered for an abdominal abscess. The patient developed encephalopathic symptoms. Cefotaxime was discontinued and hemodialysis was performed. The mental status of the patient improved. Cefotaxime was reinstituted. No further toxicity occurred.
Hepatic side effects have included transient elevations in SGOT, SGPT, serum lactate dehydrogenase, gamma glutamyltransferase, bilirubin, and serum alkaline phosphatase in less than 1% of patients. These laboratory abnormalities (which may be due to the infection) may rarely exceed twice the upper limit of the normal and elicit a pattern of liver injury, usually cholestatic and most often asymptomatic. Hepatitis, sometimes with jaundice, has been reported. Cephalosporins as a class have been associated with hepatic dysfunction including cholestasis.
Unlike other cephalosporins, severe alterations in coagulation parameters have not been reported in association with cefotaxime therapy. The methylthiotetrazole moiety found on other cephalosporins may be responsible for the development of coagulation defects.
Hematologic side effects have included granulocytopenia, eosinophilia, transient leukopenia, neutropenia, thrombocytopenia, agranulocytosis, positive direct Coombs' tests, and hemolytic anemia in less than 1% of patients. Cephalosporins as a class have been associated with aplastic anemia, prolonged prothrombin time, and hemorrhage.
Renal side effects have included interstitial nephritis and transient increases in BUN and creatinine in less than 1% of patients. Reversible fever, azotemia, pyuria, and eosinophilia are the hallmarks of cephalosporin-induced interstitial nephritis. Cephalosporins as a class have been associated with renal dysfunction and toxic nephropathy.
Dermatologic side effects have included rash, urticaria, pruritus, and cases of erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and telangiectasia.
Cardiovascular side effects have included potentially life-threatening arrhythmias following rapid (less than 60 seconds) bolus administration through a central venous catheter (less than 1%).
Genitourinary side effects have included moniliasis and vaginitis.
