Stop taking it.: The half life of Allegra (fexofenadine) is 14.5 hours in normal individuals. It is metabolized mainly through the liver and GI tract so if you have liver disease it may be metabolized slower. This means that in a normal individual about half of the medication is left after 14.5 hours.
