Summary
Kanamycin is nephrotoxic and ototoxic, and cephalosporins have been reported occasionally to add to renal injury when given with aminoglycosides. Cefaclor is among the cephalosporins with a lower nephrotoxic potential, so the added risk is modest but relevant in patients with existing renal impairment.
What this interaction means in plain words
Cefaclor and Kanamycin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive nephrotoxicity, with possible reduction of aminoglycoside clearance when renal function worsens.
What to do
Monitor serum creatinine and urine output during combined therapy, and monitor aminoglycoside levels and hearing where applicable. Adjust doses to renal function.
What to ask your pharmacist
