I Started Taking Celecoxib About Six Weeks Ago --- 200mg

I started taking celecoxib about six weeks ago --- 200mg x 2/day. This afternoon I started passing blood in my urine. Am assuming the celecoxib is causing the problem. Will contact my gynecologist on Monday. Will
quit taking the celecoxib immediately. Experienced dizziness several days ago but just attributed to inner
ear problems which I have occasionally. I do have back problems which the celecoxib seemed to help.
