  9. Q. Why should I avoid taking Allegra with fruit juices?
    A.

    We recommend that you take all medications exactly as directed on the product label. Makers of Allegra direct patients to take the medication with only water for maximum effectiveness. Fruit juices can make it harder for your body to absorb Allegra, thereby reducing its effectiveness. Like fruit juices, antacids can inhibit absorption of Allegra and should not be taken with the medication.
