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 couldn't 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 can't work. Could the medications be causing the sensitization?
