What is Fexofenadine?

Fexofenadine is an antihistamine which comes in tablet form. It’s used to treat a number of allergies including hayfever, conjunctivitis, eczema and insect bites or stings. 

How does Fexofenadine work?

Fexofenadine works by intercepting the histamine receptors in the body. Histamine is a chemical which is produced in response to the presence of an allergen, it's what causes the symptoms of an allergic reaction to occur, setting off a chain reaction within the body. An antihistamine, like Fexofenadine, interacts with this process to stop the symptoms from flaring up, or by treating them if they do so that you no longer experience unpleasant symptoms. 

How long does Fexofenadine take to work?

Fexofenadine will start to take effect after one to two hours. 

How effective is Fexofenadine?

Fexofenadine is very effective provided you take it regularly as prescribed.
