For Healthcare Professionals
Applies to ceftazidime: injectable powder for injection, intravenous solution
Discontinuation of ceftazidime may be necessary in severe, prolonged cases of diarrhea. Pseudomembranous colitis has been reported and should be considered if the patient does not respond to discontinuation of ceftazidime.
Gastrointestinal side effects reported in less than 2% of patients have included diarrhea, nausea, vomiting, abdominal pain, and pseudomembranous colitis. Oral candidiasis has been reported in less than 1% of patients. Clostridium difficile associated diarrhea has also been reported.
Mild hypersensitivity reactions, such as rash, pruritus, and fever, have been reported and may necessitate discontinuation of ceftazidime. A case of asthma induced by occupational exposure to ceftazidime has 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.
A patient with sensitization to aztreonam showed cross-reactivity to ceftazidime. Ceftazidime and aztreonam contain the same side chain, which may explain the cross-sensitivity.
Hypersensitivity reactions including rash, pruritus, and fever have been reported (2%). Cross reactions may occur in penicillin-allergic or aztreonam-allergic patients. Rarely, angioedema and anaphylactic reactions have occurred. Allergic reactions including cardiopulmonary arrest have been reported during postmarketing experience. Cephalosporin class antibiotics have been associated with Stevens-Johnson syndrome, erythema multiforme, and toxic epidermal necrolysis.
Although increases in serum creatinine do not necessarily indicate renal toxicity, urinary alanine aminopeptidase (AAP) has been found to be significantly increased in some patients and may indicate renal tubular cell damage.
Renal side effects have included transient increases in serum creatinine and BUN. Renal impairment has been reported during postmarketing experience. Cephalosporins as a class have been associated with renal dysfunction and toxic nephropathy.
Nervous system side effects reported in less than 1% of patients have included headache, dizziness, paresthesia, and seizures. Encephalopathy, coma, asterixis, neuromuscular excitability, and myoclonia have occurred in patients with renal dysfunction who received unadjusted doses of ceftazidime.
Ceftazidime-induced encephalopathy has been reported in an 80-year-old man with underlying renal dysfunction. This patient became incoherent and tremulous and had severe myoclonic jerking in all extremities. Therapy was discontinued and symptoms abated, but reappeared on rechallenge with a smaller dose. Symptoms again resolved with discontinuation of ceftazidime therapy. Several other cases of ceftazidime-induced encephalopathy, and hallucinations have been reported. In most cases the patients had underlying renal dysfunction. Symptoms were similar and resolved with dose reduction or drug discontinuation.
Neurologic reactions may be more likely to occur in patients with underlying renal dysfunction. Close monitoring of neurologic status is recommended.
Dermatologic side effects have included pemphigus erythematosus and urticaria.
Local side effects have included phlebitis and inflammation at the injection site.
Other transient hematologic effects, such as thrombocytopenia, thrombocytosis, and leukopenia, have been observed less frequently.
Hematologic side effects have included transient eosinophilia, positive Coombs test without hemolysis, thrombocytosis, leukopenia, neutropenia, agranulocytosis, thrombocytopenia, and lymphocytosis. Cephalosporins as a class have been associated with aplastic anemia, hemolytic anemia, prolonged prothrombin time, hemorrhage, neutropenia, pancytopenia, and agranulocytosis.
Hepatic side effects have included transient increases in AST, ALT, GGT, and alkaline phosphatase. These elevations generally resolve after discontinuation of therapy. Hyperbilirubinemia and jaundice have been reported during postmarketing experience. Cephalosporins as a class have been associated with hepatic dysfunction, including cholestasis.
Genitourinary side effects have included vaginitis and candidiasis. Cephalosporins as a class have been associated with false-positive tests for urine glucose.
Other side effects have included superinfection.
