A member asked:

Is there a test an allergist can do that will confirm my allergy to antihistamines? i had hives after taking dye free benadryl (diphenhydramine).

Drug test: Bring the medication you reacted to to the allergist, you may have reacted to a component in it that you are not aware of. Testing will follow depending on the ingredients.

Drug allergy: Allergic reactions to Benadryl (diphenhydramine) are very rare. See an allergist for evaluation.

True allergy to benadryl (diphenhydramine). Can i take claritin? Are they different enough that it shouldn't give me the instant hives that Benadryl (diphenhydramine) does?
