When the same allergen is encountered again, it binds directly to the IgE antibody stuck to the outside of mast cells. This causes the mast cells to release chemicals such as histamine. Histamine is an example of a chemical mediator - a special messenger chemical that immune cells use to talk to each other.

Antihistamines: These can help decrease allergy symptoms. They may be used daily during allergy season or just when allergy symptoms occur. There are many different antihistamines. If one doesn't work, another can be tried. Some can make you sleepy and some do not. They may also affect thinking and your reflexes. Because of this, it is best to avoid a sedating antihistamine, especially if you will be driving or using any kind of machine. If possible, it is best to use a non-sedating or less sedating antihistamine.
