給藥方式
可能的副作用
- Gastrointestinal upset (anorexia, vomiting, diarrhea)
- Hypersensitivity reactions (rashes, fever, eosinophilia, anaphylaxis)
- Salivation, tachypnea, and excitability (reported in dogs)
- Emesis and fever (reported in cats)
- Nephrotoxicity (rare)
- Toxic epidermal necrolysis (rarely reported in cats)
- Antibiotic-associated diarrhea or gut flora alteration
注意事項與禁忌
- Known hypersensitivity to cephalosporins
- Patients with septicemia, shock, or grave illness (oral absorption is unreliable; parenteral routes preferred)
- > **Hypersensitivity Cross-Reactivity**: Use with caution in patients with documented hypersensitivity to other beta-lactam antibiotics (e.g., penicillins, carbapenems), as cross-reactivity can occur. * **Renal Impairment**: Use cautiously and consider dose reduction in patients with renal dysfunction or those receiving concurrent nephrotoxic drugs. * **Critically Ill Patients**: Do not use oral systemic antibiotics in patients with shock or septicemia due to delayed or diminished GI absorption. * **Laboratory Interference**: May cause false-positive urine glucose tests (with cupric sulfate solutions like Clinitest) and falsely elevated serum/urine creatinine (with Jaffe reaction).
藥物相互作用
- Probenecid: Competitively blocks the tubular secretion of cephalosporins, thereby increasing serum levels and prolonging serum half-lives.
- Aminoglycosides: Increased risk of nephrotoxicity. Do not mix in the same syringe.
- Amphotericin B: Increased risk of nephrotoxicity.
- Loop diuretics (e.g., furosemide): Increased risk of nephrotoxicity.
