Does anyone know of ANYTHING that might have INCREASED your sensitivity to meds/herbs?
If you developed the condition of MCAS (mast cell activation syndrome), which some people suffer from on this forum, that can make you hypersensitive to supplements, drugs, foods and even environmental chemicals.
Here are the diagnostic criteria for MCAS. MCAS is hard to diagnose though, because its symptoms vary a lot from one patient to the next.
This is a list of MCAS symptoms.
MCAS can be treated to a degree with antihistamines and mast cell stabilizers to reduce mast cell activation. The sort of drugs used in MCAS are these:
H1 antihistamines — hydroxyzine, cetirizine
H2 antihistamines — ranitidine, famotidine
Mast cell stabilizers — NasalCrom, GastroCrom, ketotifen
