Allegra: Why Antihistamines Work Best
Allergies are the body's response to foreign substances. Some doctors even consider allergies as chronic illnesses because they tend to re-occur. The substances that cause allergy or allergens are sometimes identified while in some cases, are not. Typical symptoms of allergies include sneezing, redness of the eyes, appearance of rashes and difficulty in breathing. Most allergies are treated with antihistamine drugs such as Fexofenadine hydrochloride. Popular brand names include Allegra and Telfast.
Belonging to the second/third generation of antihistamines, Allegra (Fexofenadine) is known to make patients less drowsy. Because of this, this type of allergy medication has become more popular compared to the older allergy drugs. Manufactured by Sanofi Aventis, Allegra has been approved by the US Food and Drug Administration as a prescription medicine to treat symptoms of allergic rhinitis.
Seasonal Allergies
Among the many types of allergies, seasonal allergies or hay fever is probably the most common. Triggered by allergens that include tree pollen and mold in the spring, weed and grass pollen during the summer and ragweed in the fall, seasonal allergies are effectively treated by antihistamines like Allegra.
Other Allergy Medications
In addition to antihistamines like Allegra, there are other types of medication that can be used to treat the symptoms of allergy. These medications include decongestants, mast cell stabilizers, anti-cholinergics and corticosteroids. They even come in a variety of forms such as nasal spray, pills and eye drops. It is very important that you check out possible side effects for each medication before taking them to know what you should expect.
Compared to Allegra antihistamines, these medications are not as effective. Mast cell stabilizers can not treat watery eyes; decongestants are only good for congestion; anti-cholinergics are best for runny nose alone; and corticosteroids work best if they are in the form of nasal spray.
Choosing What is Right for You
Most people choose allergy medication on the basis of their effectivity during past allergy episodes. If you have not found the right allergy drug for you, then you should seriously consider asking your doctor. Determining what exactly causes your allergy is the challenging part. You might undergo testing such as skin test in order to find out the substance that reacts adversely with your immune system.
There are many brands of allergy medication and you and your physician should discuss the ingredients of these products to know what is right for you and your lifestyle. Depending on your preference, you may also choose if you are comfortable with taking the tablet or pill form, liquid or spray. Your doctor may even describe several allergy medications to treat the wide range of symptoms but for more convenience, medication such as Allegra can already cure all allergy symptoms.
Where to Buy Allegra
Since Allegra is a prescription drug, you would have to obtain a prescription from your doctor. This medication is readily available at pharmacies and you can even order them online. Just make sure that the online pharmacy has proper documentation in order to be sure that you receive genuine Allegra medication.
