Possible food and drug interactions when taking Allegra
Check with your doctor before combining Allegra with erythromycin (E.E.S., Ery-Tab, PCE) or ketoconazole (Nizoral). These drugs may increase Allegra's effects.
Allow a little time between a dose of Allegra and antacids such as Maalox that contain aluminum and magnesium. This type of antacid can decrease Allegra's effects.

Reserpine (Diupress, Hydropres)
You should also avoid Allegra-D if you have a pacemaker and take digoxin (Lanoxin). And you should not combine it with over-the-counter antihistamines and decongestants.
Allegra-D should not be taken with fruit juices; combining the two can induce wheals (small itchy swellings) and rash-like symptoms.
