Not many are aware of this fact, but Fexofenadine is marketed as Allegra. It is basically an antihistamine medicine which is used for treating allergic reactions or symptoms. It is a successor and at times, is also an alternative to terfenadine. The medicine is used to treat allergies which are usually seasonal.
Fexofenadine is used to treat seasonal allergies which have synonyms such as "pollen allergy" or "hay fever" which are the most common allergies in today's world. An estimate of 35 million Americans suffer from "hay fever". The symptoms of these seasonal allergies include watery eyes, runny nose and itchy throat. It is used to treat itching of the skin and other conditions which are prescribed by the doctor. The medication contains antihistamine which works against histamine in the body. The natural histamine is released from mast cells of the histamine storing cells and attaches itself to the other histamine-receptor cells. When this attachment occurs, the cells are then activated to release chemicals that produce the effects which are related to the allergy. The drug is only capable of being effective with second-generation antihistamine such as the loratidine, zelastine and cetirizine. The drug is generally used to treat the symptoms of hay fever in both adults and children who are of six years and older.
Allegra is also used to treat chronic hives. Chronic hives are also known as "chronic urticaria" which manifests itself through red, raised bumps (hives) and itching. To be diagnosed with chronic hives or "chronic urticaria" a person needs to experience an outbreak of hives and its consequent for atleast 6 weeks. The drug is used to reduce the hives and the itching in people.
