What special precautions should I follow?
Before taking fexofenadine:
Tell your doctor and pharmacist if you are allergic to fexofenadine or any other medications.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
If you are taking antiacids (Maalox®, Mylanta®), take them a few hours before or after taking fexofenadine.
Yell your doctor if you have or have ever had kidney disease.
