Allergy is an abnormal reaction of the body’s immune system that occurs when it reacts to a substance producing allergy called allergen. Among all types, antihistamines are a popular class of allergy medicines. They work by blocking the action of histamine to reduce or prevent the typical symptoms of allergic symptoms such as swelling, itching, red and watery eyes.

Allergy is an abnormal response of the body’s immune system that happens when it responds to a substance that produces allergy. Substances that produce such allergic reactions are called allergens. A person may have an allergy to a particular substance; while others may not have an allergy to the same substance.

Allergens can enter the body through ingestion, inhalation or through the skin. These invaders stimulate the white blood cells to produce antibodies that bind to mast cells. In the course of rupturing the mast cells, an endogenous substance called histamine is released. Histamine is a biochemical substance that triggers an allergic reaction.

Mild allergy symptoms include a rash itchy or watery eyes, sore throat, a runny nose, and a rash. Serious symptoms of allergy include sneezing, swelling of lips, and trouble breathing, etc. The most severe form of allergic reaction is called anaphylaxis or anaphylactic shock. This severe form of allergic reaction is most commonly observed in persons who have a family history of allergies.
