People who eat five servings of fruits and vegetables every day live longer than people who don't. But even if you'd rather have a slice of apple pie than an apple, you can make healthier choices, at least avoiding the foods you know absolutely aren't good for you [source: Paddock]. NEXT.
Fexofenadine is the active metabolite of terfenadine. It is a selective histamine H 1 receptor antagonist that does not cross the blood brain barrier; therefore, it is not associated with sedation or adverse cognitive effects. Unlike older antihistamines, fexofenadine does not have anticholinergic activity.here have been no comparative trials with fexofenadine and the intranasal nonsedating antihistamines (azelastine and levocabastine) in patients with seasonal allergic rhinitis. As with other oral nonsedating antihistamines, fexofenadine has little effect on nasal congestion.
Why is this medication prescribed? Fexofenadine is used to relieve the allergy symptoms of seasonal allergic rhinitis (''hay fever''), including runny nose; sneezing; red, itchy, or watery eyes; or itching of the nose, throat, or roof of the mouth in adults and children 2 years of age and older.
