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 Nabumetone 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; Nabumetone 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.
