My husband began taking blood pressure meds (amlodipine and benzepril) and antidepressants (Celexa) about 5 yrs ago (age 40). He has over that same time developed allergic reactions to vinegar, garlic, rosemary, and tree nuts. If he even touches these things he has trouble breathing and develops itching or hives. He even found he couldnt do wood working with walnut wood. Allergy testing does not show immune system response, so these are anaphylactoid not anaphylactic. This has gotten to be very debilitating as standard allergy meds knock him out for 16-20 hrs. So he cant work. Could the medications be causing the sensitization?
Many academicians have analyzed your type of questions and have generated a lot of information whether this causes allergy. Analyses have not fetched the cure because of diverse opinions and failure to find a solid approach. Only Ayurveda has the answer by orally taking safe herbals over some months or even more than a year and find enhanced immunity to prevent such allergens from making a reaction in your body. But it's not less than a feat to gulp pure herbals being unpalatable in taste, coarse looking and reminding of pre-historic era. Who cares about scientific sanctity of such herbs. Though, of late people are switching to Ayurveda successfully to find an answer. There are companies like Himalaya and others who contributed a lot to translate findings in modern terms. If I were your doctor, I would straightway advise you to try Hard Chat Doctor.
