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.
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.
Fexofenadine will start to take effect after one to two hours.
Fexofenadine is very effective provided you take it regularly as prescribed.
Fexofenadine hydrochloride is the active substance in the medicine.
The other ingredients are: powdered cellulose, mannitol (E421), maize starch, croscarmellose sodium, colloidal anhydrous silica, magnesium stearate. Tablet coating: opadry pink film-coating mixture containing hypromellose (E464), titanium dioxide (E171), macrogol 400, allura red AC lake (FD&C Red #40) (E129), and iron oxide, black (E172).

Fexofenadine should be swallowed whole. Do not split or crush the tablet unless it specifies on the packet that it's suitable to do so. This can make the medicine less effective as it stops it from being absorbed correctly by the body.
