Allergic reactions are basically the body's abnormal and troubling reactions towards certain particular substances known as allergens. Allergies are usually hypersensitive states of being when an individual may suffer extreme reactions because of certain allergens that are perfectly harmless to others.
The significance of allergens for allergy reactions largely depends on the immune system of the body. Many allergic people develop an excess amount of antibody IgE in the presence of certain allergens. These IgE antibodies attach themselves to a component of the immune system called mast cells. These mast cells then work on releasing of leukotrienes and histamines from some other cells thereby creating allergic reactions. In simple words, allergic reactions are a result of over-working of an individual's immune system.
Apart from IgE infused allergies, certain other allergic reactions may also occur without IgE's intervention, for example the food related allergies aren't related to IgE, but to some bacteria that can create the antigen-antibody issues thereby leading to allergic reactions.

The most common form of treatment for allergy is the usage of oral antihistamines, which have been quite popular since 1930s. They are best known to provide temporary relief in case of allergic attacks. Oral antihistamines block the secretion of histamines thereby giving relief from reactions like sneezing, hives and other related symptoms.
Nasal and Oral Decongestants
Oral and Nasal Decongestants can work effectively in healing nasal congestion; however they aren't very effective in treating nasal secretions or sneezing. Decongestants work on drying the tissues present in the nasal passages thereby reducing the swelling in nasal membranes. These decongestants can be found in the form of pills, sprays, liquids and even nose drops. Some of the side-effects that can be caused by these decongestants include lose of appetite, general irritability and insomnia.
