Summary
Corticosteroids combined with NSAIDs increase the risk of gastric irritation, ulceration and gastrointestinal bleeding. With a topical ophthalmic or otic dexamethasone-tobramycin product, systemic exposure is minimal and the interaction is unlikely to be relevant.
What this interaction means in plain words
Dexamethasone-tobramycin and Naproxen have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Dexamethasone-tobramycin belongs to Anti Bacterial; Naproxen belongs to Musculoskeletal.
Why it happens
Topical route gives negligible systemic corticosteroid exposure; with systemic use, additive mucosal injury from NSAID prostaglandin inhibition and corticosteroid effects.
What to do
No action is needed for topical use. If systemic dexamethasone is given, consider gastroprotection with a proton pump inhibitor.
