Took Allegra Fexofenadine
Probably: If stored in cool area, it is likely ok for 2 more years after the expiration date. The US Army did a study on that and found that most drugs were good for a couple more years after the stated expiration date if stored properly. In Allegra's case, the worst would be less effectiveness. However I would caution using antibiotics, biologicals (insulin etc), and epinephrine past the expiration date ...Read more

I took Allegra (fexofenadine) that expired 1/2015 today should I be concerned or what symptoms would require seeking medical help?
Many dayquils: Unfortunately there are several formulations under the DayQuil name. If it contains phenylephrine then it's not so good to mix with the "D" in Allegra-D because it contains pseudoephedrine. Those are both stimulant decongestants and can cause rapid heart beat, elevated blood pressure and nervous side effects. ...Read more

Yes: Allegra (fexofenadine) is a very safe new generation antihistamine that does not cross the blood-brain barrier, so even more than the recommended dose will not lead to drowsiness or impaired reaction time.
