Nabumetone and celecoxib are both labeled for osteoarthritis and rheumatoid arthritis. Drugs@FDA records approvals of nabumetone since 1991 and of celecoxib since 1998. Pharmacies paid $0.128 per nabumetone 500 mg tablet and $0.0762 per celecoxib 200 mg capsule (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like.

What do the labels say about using others of their kind?

Nabumetone label, drug interactions

The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of nabumetone tablets and aspirin is not generally recommended because of the potential of increased adverse effects.

Celecoxib label, drug interactions

Concomitant use of Celecoxib with other NSAIDs or salicylates (e.g., diflunisal, salsalate) increases the risk of GI toxicity, with little or no increase in efficacy [see Warnings and Precautions (5.2) ].
