Anyone had an allergic reaction?

Last week my rheumatologist prescribed Relafen for my inflammation.  I started taking the relafen on a Tuesday and on Friday night I developed a rash.  The rash started on my stomach and spread around to my sides and I got just a little bit on my forearms.  I read about side effects and saw that you were supposed to stop taking it immediately if a rash developed, so I quit taking it Saturday and got in to see my PCP Monday.

My PCP thought it was definitely an allergic reaction, so I let my rheumy know and she wants me to start on another NSAID after my rash goes away.  My rash is still very much there even though I've taken some allergy medicine.  My stomach and sides are just covered.  Has anyone had anything similar happen.  ANy idea how long the rash will last?  I didn't know how long I should expect the rash to last because I've never had anything like this.

Thanks

I had a similar allergic reaction to sulfasalazine.  It took several days for the rash to clear, although I had it from head to toe, not just on my torso.  I also started taking prednisone for a bad joint flare, and that most likely cleared the rash up quicker than if I hadn't taken it.  It would have taken almost a week if I hadn't started prednisone therapy.  If your rash doesn't clear, you could ask about prednisone.  I think even low dose for a week would probably clear your rash up fairly quickly.  I would be hesitant to start another NSAID until the relafen rash is mostly gone.
