Cefuroxime
Also known as: Ceftin, Zinacef, Aprokam, Zinnat
* **Give with Food**: Administer the oral tablets with a meal to enhance drug absorption and reduce the chance of stomach upset. * **Do Not Crush**: Avoid crushing the tablets. They have a very strong, bitter taste that pets will reject. If you absolutely must crush them, mix the powder with a strong-tasting dairy product (like milk or pet-safe cheese) to mask the taste and improve absorption. * **Finish the Prescription**: Give the medication exactly as directed by your veterinarian. Continue treating for the full prescribed duration, even if your pet seems completely better, to prevent the infection from returning or becoming resistant. * **Watch for Side Effects**: Contact your veterinarian if your pet develops severe vomiting, persistent diarrhea, rash, itching, or facial swelling.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

Cautions & contraindications
- Known hypersensitivity to cefuroxime or other cephalosporins
- > **Renal Impairment**: Dosage adjustment is recommended in patients with severe renal impairment, as the drug is primarily excreted unchanged in the urine. * **Laboratory Interference**: May cause false-positive urine glucose determinations when using the copper reduction method (Benedict's, Fehling's, Clinitest). Tests utilizing glucose oxidase are unaffected. * **Coombs' Test**: Cephalosporins have caused false-positive direct Coombs' tests in humans, particularly those with azotemia. * **Nursing Mothers**: Enters maternal milk in low concentrations; potential for altering gut flora of nursing offspring.
Drug interactions
- Aminoglycosides: Potential for increased risk of nephrotoxicity; monitor renal function. However, may have synergistic or additive actions against some gram-negative bacteria (Enterobacteriaceae).
- Furosemide: Possible increased risk of nephrotoxicity.
- Torsemide: Possible increased risk of nephrotoxicity.
- Probenecid: Reduced renal excretion of cephalosporins, potentially increasing serum levels.
- Oxytetracycline: Bacteriostatic agents may antagonize the bactericidal activity of cefuroxime.
- Erythromycin: Bacteriostatic agents may antagonize the bactericidal activity of cefuroxime.
- Amphotericin B: Increased risk of nephrotoxicity; monitor renal function.
