I used to take celebrex for the last three years 200 mg twice a day . Now there is a lot of argument about that prescrebtion that those who take celebrex 400 mg a day might suffer twice heart attack than those who do not take it. My doctor changed that to apo-prednisone. Do u have any idea about this drug ? Is there side effect with this one ? Does it help with killing pain like the one I used to take it before celbrex. This one is so helpfull, since I quited it I have sever pain.
