What is Fexofenadine used for?

Fexofenadine, sometimes called Telfast or Allegra is a strong non-drowsy antihistamine prescribed by health professionals for relief from stubborn symptoms of seasonal allergic rhinitis (aka hay fever) not responding to more conventional antihistamines like Cetirizine or Loratadine.

Fexofenadine is suitable for adults aged 18 years and over who have found over the counter treatments (OTC) unable to effectively control their hay fever and allergy symptoms.

How does Fexofenadine help relieve allergy symptoms?

In susceptible individuals, when the body is exposed to pollen or another allergen (eg animal fur) an allergic reaction occurs. This causes the release of a chemical called histamine from the cells lining the nose, throat, eyes and sinuses which can cause swelling, inflammation and irritation.

Inflammation and irritation lead to the common symptoms of sneezing, runny nose and itchy eyes associated with seasonal allergic rhinitis, more commonly referred to as hay fever.

Fexofenadine works by preventing the action of histamine which causes allergy symptoms. We call medicines that counter act the effcets of histamine, antihistamines.
