Summary
Interferon alfa can occasionally cause renal toxicity and hearing disturbances, and tobramycin is an aminoglycoside with nephrotoxic and ototoxic potential. With the inhaled route systemic exposure is low, so clinically significant additive toxicity is unlikely.
What this interaction means in plain words
Interferon alfa 2b and Tobramycin inhaled 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
Theoretical additive nephrotoxicity and ototoxicity, limited by low systemic absorption of inhaled tobramycin.
What to do
Monitor serum creatinine periodically and ask about hearing changes or tinnitus during combined courses, especially in renal impairment.
