Summary
Inhaled tobramycin has low but real systemic absorption, which may be higher with renal impairment or damaged airways. NSAIDs can reduce renal function, potentially raising aminoglycoside levels and the risk of nephrotoxicity and ototoxicity.
What this interaction means in plain words
Naproxen and Tobramycin inhaled 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 and reduced renal clearance of absorbed tobramycin from NSAID-induced renal hemodynamic changes.
What to do
Monitor serum creatinine and, in at-risk patients, serum tobramycin levels. Avoid prolonged NSAID use and ensure good hydration.
What to ask your pharmacist
