Summary
Corticosteroids and NSAIDs both damage the gastroduodenal mucosa, and using them together raises the chance of peptic ulceration and gastrointestinal bleeding. With a topical ophthalmic or otic combination product, systemic exposure is limited, so the practical risk is lower than with systemic dexamethasone.
What this interaction means in plain words
Dexamethasone-neomycin-polymyxin and Parecoxib 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
Additive gastrointestinal mucosal injury from NSAID prostaglandin inhibition and corticosteroid effects on mucosal protection and healing.
What to do
Assess the route of the dexamethasone product; with topical use no action is usually needed. If systemic steroid exposure occurs, consider gastroprotection with a proton pump inhibitor and watch for GI bleeding.
