If i had a reaction (rash) to celebrex (celecoxib) could i have also have reaction to ibuprofin.

? sulfa allergy: Patients that are allergic to sulfa drugs sometimes get a rash with celebrex (celecoxib). There are different classes of anti-inflammatory medications, and it is unlikely that you are allergic to all of them. However, if you are on Coumadin or Heparin you shouldn't be taking ibuprofen. Speak to your doctor and perhaps there is some alternative treatment for you.
