What is fexofenadine?

Fexofenadine is an antihistamine, which can be used to manage symptoms of seasonal allergic rhinitis. Allergic rhinitis, commonly known as hayfever is characterised by symptoms of sneezing, itchiness and runny nose. These symptoms happen in response to allergens such as flower, grass and tree pollen. 

Fexofenadine is classified as a second-generation antihistamine. Second-generation antihistamines are less likely to cross the blood-brain barrier and cause sleepiness. In the UK first-generation antihistamines are mainly used as sleeping aid products, whereas second-generation antihistamines as medicines to manage hayfever symptoms.

Fexofenadine starts to work rapidly, usually within one hour of taking it. Fexofenadine has a long duration of action, which means it works for 24 hours with a single dose. Fexofenadine is effective antihistamine. It controls the main symptoms of hayfever including an itchy and runny nose, sneezing, itchy throat, watery and red eyes. A dose of 120mg (over the counter dose) has shown to be as effective as loratadine 10mg and cetirizine 10mg (other over the counter antihistamines). When used with pseudoephedrine, a decongestant available from pharmacies, fexofenadine was found to produce greater improvements in quality of life than loratadine (Simpson & Jarvis, 2000).
