The physical reaction to an allergy is usually very unpleasant. In these cases, anti-allergy medication is highly appreciated.
When a person suffering from allergies comes into contact with their personal allergen, such as pollen, food or an insect bite, the body releases the messenger substance histamine.
Histamine attaches itself to the histamine receptors in the cells, causing an allergic reaction in the form of a skin rash, itching, redness of the eyes, swelling, sneezing or a cold.
