*Histamines. Antibodies are far less disruptive. Histamines protect us from larger invaders like worms and other parasites. Antihistamines antagonize histamines at receptor sites, preventing the itchy, red, swelling reaction we associate with an allergen.
Acktually – IgE(/antibodies) are bound to the surface of mast cells. Antigens/allergens bind to the IgE receptor and actives the mast cell, releasing histamines. Allergy can actually be treated with anti-IgE (monoclonal) antibodies (Omalizumab)!

Thank you for the detail! I just repeated the dumbed-down explanation given to me by my allergist.
Are you sure histamines are larger than antibodies?
That’s 17 atoms if I can count correctly.
Antibodies are made of proteins and should therefore be much larger.
I just confirmed. They’re only 17 atoms in size. My memory failed me. I edited the comment. Thanks for the correction!
