At one time, I had a prescription for Celebrex, another useful pain medication, and my doctor finally took me off it because he was taking too much flak from the insurance company
for a
dosage that was too low! I was taking one a day, and the standard
dosage was 2X/day. You would think that for painkillers, the minimum dosage would be preferable, to avoid developing tolerance, but often that is not the case.
