Histamines are a group of chemicals that have 3 main functions in the body and these functions are controlled by the cells they are release from and the nature of the receptors that are stimulated with release
Perhaps most evident to horse folks are those histamines that are released from some types of white blood cells that help the body fight infection but also cause allergic reactions that are common in horses. This will be the main focus of this article. For more on the other uses of antihistamines refer to the links above for articles on these specific conditions.

Horse folks become aware of histamines when it causes allergic reactions in their horses. Some of the diseases we attribute primarily to the inappropriate release of histamine are:
Hives (First stages of anaphylaxis, contact hypersensitivity, and possibly food or inhaled hypersensitivity)
Culicoides Hypersensitivity (Queensland Itch or Sweet Itch)
Allergic Rhinitis (Sneezing and Head Shaking)
This article deals with the use of antihistamines in allergic reactions, including efficacy, side effects and dosages...access article.
