Substances that cause allergies are called allergens. Most allergies result from a combination of inheritance genes and environmental exposures pollens, animal dander, etc. A hypersensitive response, or allergic reaction, is the result of the interaction among the allergen itself, mast cells and immunoglobulin E IgE.
The result is a prompt release of inflammatory chemicals that can cause swelling of rhinocort coupon astrazeneca, itching, engorgement of blood vessels, increased secretions and bronchospasm tightening of muscles that surround the airways. If the allergen is ingested, the allergic reaction may primarily occur in the mouth, stomach, and intestines. The most common allergens are pollens and dust mites.
They reduce swelling of blood vessels inside your nasal cavity in the upper airway to make breathing easier. However, use of decongestants for more than 7 days can lead to rebound congestion and therefore they are not recommended to be used regularly or for long term. Examples of commonly used decongestants include pseudoephedrine and phenylephrine. Montelukast, a leukotriene antagonist, has been used for the management of allergic rhinitis. Montelukast blocks the effect of potent inflammatory substances released from cells including mast cells and eosinophils, thus improving symptoms of allergic rhinitis, such as nasal congestion, rhinorrhea, sneezing and nasal itching.

When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach.
Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock. Asthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath.
