Allergies are an amplified immune system reaction or response to certain substances (allergens) that are usually not considered dangerous. Generally, the auto immune system functions as the body’s defense against harmful elements like bacteria and viruses. Depending on each individual, the immune system reacts to allergens differently effecting the severity of reactions.
Initial exposure to allergens causes the immune system to recognize the identified substances. Additional exposures can lead to the auto immune system over-reacting to allergens. This is attributed to stored information by the auto immune system identifing allergic substances and over-responding to allergens.
Allergic itch results from the bodes chemicals being released by cells. One example of a body chemical is histamine. The release of cellular chemicals is do to exposure of a allergen to a sensitized immune system. Other symptoms include mucus production, swelling, rashes, muscle spasms, and hives.
Although allergic skin ith symptoms vary individually, exposure to common allergens produces some degree of skin itch irritation and discomfort. On rare occasions, some people may experience serious life-threatening allergic reactions and need to seek immediate medical attention.

They include contact with skin or contact dermatitis, breathing passage, and eye irritation. Allergens are also present in food, medication, household products, fabrics, carpeting and other syntheticly producted products or chemical agents.

Medically recommended treatments in alleviating allergies:
1. Antihistamines – Antihistamines are considered to be an effective symptoms management treatment for skin allery itching and inflammation. Short-acting histamines can help relieve mild allergic reactions but have the side-effect of drowsiness. Anthihistamies administration should be limited with children as they may have an adverse affect. Studies show that excessive use can negatively impact learning. Most short-acting histamines are available Over-The-Counter. Long-acting histamines are the better alternative as they stay in the system longer requiring less frequent doses. Lower doses reduce the potential risk to children and produce lower side-effects. Higher doses, or doses that exceed manufacturer directed use, may require a physicians order. Examples of this type include cetirizine (Zyrtec) and fexofenadine (Allegra).
2. Decongestants – Decongestants are used to clear air and nasal passages. However, caution must be followed using nasal spray decongestants as they may cause additional congestion. Decongestants in tablet or capsule form are better because they do not treat the nasal congestion directly.
3. Nasal Sprays – Corticosteroid sprays are proven to be safe and effective for individuals who do not react to antihistamines. Examples of these nasal sprays are triamcinolone (Nasacort AQ), fluticasone (Flonase), and mometasone (Nasonex).
Allergy shots (immunotherapy) are recommended for hard to control allergen or allergen exposure. Anti-allergen injections are prearranged, with graduating dose depending on the severity of the allergy individually. Allergy shots stabilize the body from over reacting to allergens. However, they are not effective for everyone and require the doctor's prescription and administration for use.
Extreme reactions (anaphylaxis or anaphylatic shock) require epinephrine, that can treat life-threatening. Anaphylatic symptoms require immediate medical attention.
