Hi, I have been taking Celebrex approx 1 month and I ve developed a rash on parts of my body, red bumpy spots almost blister like, I am on meds for RA, but I m fairly sure this is a result of the Celebrex..nothing else new has been in my system..my question is , and of course I will stop the Celebrex, but will this rash subside on its own or is there something I should be doing to counteract this reaction,ie Benadryl or?
