Allergies
Histamine is a substance produced by the body when it reacts to a foreign substance such as pollen or pet fur (this is called an allergen). Histamine causes the symptoms of allergic reactions.

In allergies like hay fever and pet allergies, histamine causes inflammation of the nose, eyes or airways, resulting in itchy, watery eyes, a runny, blocked or itchy nose and sneezing. In allergic skin reactions histamine causes skin inflammation, rashes and itching.

Chlorphenamine blocks histamine from binding to its receptors in various parts of the body. This stops it from causing the symptoms of an allergic reaction. Piriton usually starts to relieve symptoms within half an hour to an hour after taking a dose.
