Histamine is a chemical that is normally produced in the body and stored in allergic cells, such as mast cells and basophils.
In people with allergies, histamine is released from these cells in a response to allergens.
Histamine binds to the histamine receptor, which is present on various cells in the body, and results in allergic symptoms such as sneezing, itchy eyes, itchy nose, hives, or even anaphylaxis.
Antihistamines are medications that block the receptor for histamine, thereby stopping the symptoms that histamine causes.
