This
medicine contains the active ingredient cetirizine, which is a type of
medicine called a non-sedating antihistamine. It works by preventing the
actions of histamine.
All this results in the symptoms of an allergic reaction. In hayfever,
histamine causes inflammation of the nose, eyes, skin or airways and
results in itchy watery eyes, a runny nose, sneezing and nasal
congestion.
The released histamine then binds to its receptors (H1 receptors),
causing a chain reaction that results in allergic symptoms. It causes an
increase in blood flow to the area of the allergy, and the release of
other chemicals that add to the allergic response.
