注意事項與禁忌

• Known hypersensitivity to cephalosporins
• Septicemia, shock, or grave illness (oral absorption is unreliable; parenteral routes required)
• > **Cross-Reactivity Warning:** Use cautiously in patients with documented hypersensitivity to other beta-lactam antibiotics (e.g., penicillins, carbapenems) due to potential cross-reactivity (up to 15% in humans; unknown in veterinary patients). * **Renal Impairment:** Patients with diminished renal function may require dose adjustments and intensified renal monitoring, as the drug is primarily excreted unchanged in the urine. * **Laboratory Interference:** * May cause false-positive urine glucose tests when using cupric sulfate solutions (e.g., Clinitest®). * May falsely elevate serum/urine creatinine values when using the Jaffe reaction. * May cause a false-positive direct Coombs' test. * May falsely elevate 17-ketosteroid values in urine.

藥物相互作用

• Probenecid: Competitively blocks the tubular secretion of most cephalosporins, thereby increasing serum levels and serum half-lives.
