I took Celebrex on and off for over 10 years for psoriatic arthritis (200mg twice a day). It was the only NSAID I was able to tolerate due to stomach ulcers. Even with it I had to take Nexium as well.

I finally got my arthritis under control with several other meds that make Celebrex look like a tame drug in comparison, so i dropped the Celebrex about 2 months ago. So far so good.

If you start noticing ANY stomach issues, tell your doctor (and maybe start a PPI like Priolsec which is available OTC). you don't want to let it get out of control, trust me. It's not a fun path.
