Telfast® | Telfast (Fexofenadine) - 120mg (30 Tablets)

How does Telfast (Fexofenadine) work?

Telfast 120mg tablets contain the active ingredient fexofenadine, which is a type of medicine called a non-sedating antihistamine. It works by preventing the actions of histamine

Histamine is a substance produced by the body as part of its defence mechanisms. It is stored in cells called mast cells, in almost all tissues of the body. When the body reacts to a foreign substance (known as an allergen, eg flower pollen), the mast cells stimulated by the allergen release their stores of histamine.

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.

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.

Fexofenadine works by blocking histamine H1 receptors. It does not prevent the actual release of histamine from mast cells, but prevents it binding to its receptors. This in turn prevents the release of other allergy chemicals and increased blood supply to the area, and provides relief from the typical symptoms of allergies.

Fexofenadine 120mg is used to relieve the symptoms of hayfever

Fexofenadine is called a non-sedating antihistamine as it does not enter the brain in significant amounts and is therefore unlikely to cause drowsiness. However, people react differently to medicines and extremely rarely some people may experience some drowsiness.
