What Are The Main Differences Between Allegra And Allegra

Allegra-D comes in a 12-hour and 24-hour tablet. The 12-hour formulation contains 60 mg of fexofenadine and 120 mg of pseudoephedrine while the 24-hour formulation contains 180 mg of fexofenadine and 240 mg of pseudoephedrine. Allegra-D is only recommended for adults and children who are 12 years of age or older.
Regular Allegra comes in an oral tablet, orally-disintegrating tablet, and liquid suspension. The 12-hour tablet contains 60 mg of fexofenadine while the 24-hour tablet contains 180 mg of fexofenadine. Adults and children who are 12 years of age and older can take Allegra tablets, but there are lower-strength versions available to treat allergic rhinitis in children aged 2 to 11 years old.

Why Is This Medication Prescribed
Pseudoephedrine is used to relieve nasal congestion caused by colds, allergies, and hay fever. It is also used to temporarily relieve sinus congestion and pressure. Pseudoephedrine will relieve symptoms but will not treat the cause of the symptoms or speed recovery. Pseudoephedrine is in a class of medications called nasal decongestants. It works by causing narrowing of the blood vessels in the nasal passages.
What Is Fexofenadine And Pseudoephedrine What Is Allegra
Allegra-D is a combination of an antihistamine and a . Fexofenadine is an oral, “second generation” antihistamine that is used to treat the signs and symptoms of allergy and hives. It is similar to the other second generation antihistaminesloratadine , cetirizine and azelastine .
Histamine is a chemical that is responsible for many of the signs and symptoms of allergic reactions, for example, swelling of the lining of the nose, sneezing, and itchy eyes. Histamine is released from histamine-storing cells and then attaches to other cells that have receptors for histamine. The attachment of the histamine to the receptors causes the cell to become “activated,” releasing other chemicals that produce the effects that we associate with allergy .
Fexofenadine blocks one type of receptor for histamine and thus prevents activation of H1 receptor-containing cells by histamine. Unlike the first generation antihistamines, fexofenadine and other second-generation antihistamines do not readily enter the brain from the blood. Therefore, they cause less drowsiness and are called non-sedating antihistamines. Pseudoephedrine causes blood vessels in the nasal passages to narrow . Vasoconstriction reduces nasal congestion by preventing fluid from draining from blood vessels into nasal passages. The FDA approved Allegra-D in December 1997.
