Can you outgrow a penicillin allergy?07/23/2008 |
I saw the answer to the question about being told of a pencillin allergy at a very early age. I also was told that I was allergic to pencillin though I have no idea what happened or when. I am now in my early 50`s and recently took one (1) 500 mg amoxicllin before I realized it was a pencillin deriative. I did not have any reaction - I also took cephalexin and I think the only reacion was vaginal itching and some joint pain but I also take Lipitor). Does this mean I can take now these drugs without life threatening side effects?
Not exactly. You need to be skin tested to penicillin and possibly the cephalosporins even if the skin tests to penicillin are negative.
