Millions of people suffer under the burden of having to deal with seasonal allergies. Unpleasant and often uncomfortable common allergy symptoms may include sneezing, runny nose, nasal congestion, itchy eyes, and itchy throats. These discomforts when left untreated can often make life seem very unbearable. There is no need to continue to put up with these discomforts day in and day out because Allegra is here. Allegra is a prescription medication that can help relieve all these symptoms and let you feel like yourself again. Allegra uses a powerful antihistamine and decongestant that includes Fexofenadine. Fexofenadine is a medication designed to aggressively combat seasonal allergy symptoms. Antihistamines are medications that block the action of histamines, a natural substance produced by the body during an allergic reaction. When taken twice daily Allegra can provide 24-hour allergy relief for patients 12 and older. Because Allegra contains Pseudoephedrine an over the counter decongestant, people taking MAO inhibitors or suffering from high blood pressure, should not use this product.
