Summary
Oral neomycin is poorly absorbed, so systemic aminoglycoside exposure is usually small. Cefuroxime has low intrinsic nephrotoxicity. Additive kidney or ear injury is unlikely unless neomycin is absorbed, for example with bowel damage or renal failure.
What this interaction means in plain words
Cefuroxime and Neomycin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Cefuroxime belongs to Anti Bacterial; Neomycin belongs to Anti Bacterial.
Why it happens
Theoretical additive nephrotoxicity and ototoxicity that requires systemic aminoglycoside absorption, which is minimal with oral neomycin.
What to do
No routine action is needed when renal function is normal. Check renal function if the patient has renal impairment or prolonged neomycin exposure.
What to ask your pharmacist
- Is there anything I should notice while taking both?
