Allergens are substances that are otherwise harmless to the human body – pollen, pet dander, dust and so on; but the body reacts negatively to them treating them as inimical enemies to be guarded against. This reaction in the body is to produce histamine and it is this histamine that causes the classicallergy symptoms – the runny nose, sneezing, watery or itchy eyes and so on.
Linda B. Ford, M.D., director of the Allergy and Asthma Center near Omaha, Nebraska advises that as soon as these allergicsymptoms begin to manifest, it is advisable to take an antihistamine.
Over the counter drugs such as Zyrtec, Allegra and Claritin are effective antihistamines and also are safe to take over the longer duration.
Another option for curbing allergic reactions is Chloraseptic Allergen Block, which helps you avoid the inevitable drowsiness that can accompany allergic medications.
This is a topical application in the form of a clear gel that is applied outside of the nose so that the allergen cannot enter your system and gets trapped outside.
Sometimes these over the counter medications may not work and then it becomes imperative to see a doctor and seek out a permanent solution once it is confirmed what exactly the allergy is.
This is usually in the form of injections that introduce allergens in increasing amounts to the system to build resistance.
