Why would allegra (fexofenadine) be prescribed?

Many reasons. Allegra is an antihistamine which can be used for itching of the skin, nose, eyes. It is mainly used to treat allergic reactions and to relieve seasonal allergic eye and nose symptoms. It is not very effective for nasal congestion unless used with another medication such as a nasal steroid or oral decongestant.
No drowsiness. The advantage of Allegra over other antihistamines like claritin, zyrtec & especially Benadryl (diphenhydramine) is that it never causes drowsiness. Allegra is designed not to cross from the bloodstream into the brain. If the medication can't enter the brain then it can't combine with histamine receptors there. Blockage of these receptors by other antihistamines results in drowsiness.
For allergies. Allegra (fexofenadine) is an antihistamine approved in the treatment of seasonal allergies as well as hives. It is now available over-the-counter without a prescription.

My body's Serum IGE count is 377.7. Can you please suggest how much time it will take to get normal. My dermatologist has prescribed allegra (fexofenadine) 180.

Answer. IgE is an antibody which can be produced in response to allergy, but also in response to parasitic/viral infections, inflammatory disorders, and a handful of less common conditions. Allegra (fexofenadine) blocks a subset of histamine responses in the body and can mask symptoms, but does not change the immune response to create IgE. The body will keep producing IgE until the trigger stops. Read more...

Hard to say. As with a single dose and a symptom that is nonspecific like a headache, it could be from the medications(as headaches are a common side effect seen in almost 20% of patient on singulair) but it could be related to so many other things going on with your body/life(including severe allergies) that either another trial or just reviewing this with your prescribing physician is reasonable.
