Howlerkarma, that is a helpful explanation and clearer (more accessible) than what I had come across previously.
My initial post brought up two separate issues - using zyrtec daily as a preventative therapy and using zyrtec as an add-on therapeutic. I was confident of the efficacy of the later (in certain instances) but was wondering about the former. Although my older DS has been taking zyrtec daily for 7 years, it wasn't to prevent reactions due to his "traditional" food allergies so I wasn't sure about having my younger DS take it daily to help prevent allergic reactions.
Your latest post plus one of your previous ones set out the reasons very well and may help someone else approach their doctors with the right set of questions.
