Six hours after taking my first mobic pill my face turned beet red along with my ears. Then my back and chest broke out with either rashes or hives. Then my face started to swell. Had to start taking benadryl immediately. Fortunately my tongue did not swell so I did not have to go to the ER. Following day the itching and rash were gone and most of the swelling in my face. Still had terrible bags under my eyes. I have taken other anti inflammatories with no problems, but my body does not like this drug.
