Allegra-D is a medication used to treat allergy symptoms and sinus congestion. Allegra-D is available over the counter in most states, but only by prescription in certain states. Allegra-D is a combination drug composed of Fexofenadine and Pseudophedrine.

Fexofenadine is an antihistamine. Fexofenadine is believed to work by blocking the action of histamines (chemicals associated with allergic reactions) in the body. Pseudophedrine is a decongestant. Pseudophedrine is believed to work by causing the blood vessels to constrict, reducing swelling in the sinus passages.

How do I take it?
Take Allegra-D as directed by your doctor, or follow the directions on the package.

Allegra-D comes in the form of a tablet.

Side effects
The FDA-approved label for Allegra-D includes a warning that people who have diabetes, high blood pressure, glaucoma, heart or thyroid disease, or prostate problems, as well as those who experience nervousness, insomnia, or dizziness while taking the medication, should consult a physician regarding its use.
