Have been happily taking Celebrex for several years with no side effects. One dr who was really pushing Merck products had me try some Vioxx samples a couple years ago. Within a few days it gave me a rash and I stopped.
Ibuprofen - if I take enough for a therapeutic dose, I start to retain fluid and have difficulty urinating after a few days, so I don't take it except for a true inflammation, for a couple of days. Asprin - makes my ears ring even more than they do normally and even buffered upsets my stomach. Tylenol (generic) I sometimes take at bedtime, but I wonder about long term liver damage even tho I don't drink. So I'm sticking with Celebrex, and hope they don't find anything wrong with that.
