Allegra is a well-known medication that combines fexofenadine and pseudoephedrine to relieve the symptoms of seasonal allergies in people twelve years old and older. These symptoms include sneezing, a stuffy and runny nose, watery and itchy eyes and an itchy throat. Fexofenadine is an antihistamine. Histamine is a naturally-occurring chemical in the body that causes the symptoms listed above. When blocked, these symptoms disappear. For its part, pseudoephedrine is a decongestant that can dry the passages of the nose and throat. It’s an important distinction, though, that Allegra clears away these symptoms but does not cure your allergies. You will still have hay fever, or whatever allergy you had before you started taking this drug no matter how long you take it. Allegra is taken with water in tablet form either once or twice a day; its effects can last for up to twelve hours or up to twenty-four hours, depending on the kind of Allegra you buy. (Its effects can last for so long because it’s what’s known as an extended-release” medication.) You want to take Allegra on an empty stomach, which makes first thing in the morning an ideal time for this drug. You especially want to make sure you don’t take this drug with apple, grapefruit or orange juice. And whenever you take Allegra, you have to follow your physician’s prescription carefully. Don’t take it more often or less often than she or he directed you to. You also want to make sure you don’t chew up or break open an Allegra tablet, as some people who dislike swallowing pills are wont to do. If you don’t swallow each tablet whole, your body is likely to absorb too much medication at the same time.

Check out a list of Allegra ingredients to be certain you’re not allergic to any one of them. If you’re not sure, you might even wish to schedule an appointment with an allergist to find out exactly what you are allergic to. Let your doctor know about every other kind of medication and herbal remedy you’re taking, too, so you can be sure that the Allegra won’t counteract with any of these drugs. In particular, be wary if you are taking a monoamine oxidase inhibitor or tranylcypromine. Your doctor should also know if you have or have ever had high blood pressure, coronary artery disease, glaucoma or urinary problems. If so, you may have to find another way to treat your allergies. When you’re taking Allegra, you might want to decrease or avoid caffeine, as sometimes caffeine plus the Allegra ingredients can lead to insomnia and increased nervous energy. Other patients, however, can drink caffeine with Allegra and not experience these problems. You also want to make sure you don’t take a magnesium or aluminum-containing antacid within a few hours of an Allegra tablet. And should you become pregnant when you are on Allegra, contact your doctor right away. She or he may discontinue your use of this drug.

Allegra can cause such side effects as heartburn and stomach pains, nausea and dry mouth, headaches, back aches and throat soreness. Seek medical help if these symptoms don’t go away or are severe. Also seek medical help should you experience any of the following rare side effects: dizziness, unexplainable anxiety, hallucinations, seizures, blurry vision, rashes or irregular heartbeats. In most cases, however, Allegra is completely safe, and many patients find it to be surprisingly fast-acting. In short, there is no reason to live with the effects of allergies all the time, even if it’s just for part of the year, when such a simple solution as Allegra is available and so effective.
