<s>[INST] I was on augmentin and became very itchy, no hives just very itchy. I went to the ER and they gave me IV Benadryl. Ever since then I have been weary about having an allergic reaction because that same day that I became itchy I also had some shrimp sushi. I have never had any food allergies and 25, but read that a food allergy can just appear at any age. What are the chances of developing a food allergy as an adult? [/INST] HI, thanks for using Chat Doctor It is understandable to be concerned. It is possible to discover allergies as an adult. If you want to determine what you may be allergic to, you should consider allergy testing. This can be in the form of a blood test or skin test. It is possible to test for a lot of different allergens at the same time. Your doctor will be able to tell you where you can have the test done. I hope this helps </s>
