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.

Allegra-D should never be taken within 2 weeks of using an MAO-inhibitor drug such as the antidepressants Marplan, Nardil, and Parnate. Also check with your doctor before combining it with the following:

Mecamylamine (Inversine)

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.

If Allegra or Allegra-D gives you an allergic reaction, avoid it in the future. Do not give either product to children under 6.

Do not take Allegra-D if you have glaucoma, urination problems, or severe high blood pressure or heart disease. Also avoid taking Allegra-D within 2 weeks of using an MAO-inhibitor drug such as Marplan, Nardil, or Parnate.
