Summary
Oral neomycin is poorly absorbed, so systemic nephrotoxicity or ototoxicity is uncommon with intact gut and normal kidney function. Absorption can increase with inflamed or damaged bowel or with prolonged high dosing, and a cephalosporin could then add to renal risk.
What this interaction means in plain words
Cefuroxime and Neomycin po have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Possible additive nephrotoxicity if neomycin is systemically absorbed.
What to do
No routine action is needed with short courses. Monitor renal function if therapy is prolonged, bowel is damaged, or renal impairment is present.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
