After being exposed for the first time to the chemical substance, the immune system becomes sensitive to it. So when the person exposes for a second time to the allergen, the body suffers an allergic reaction. Anaphylaxis occurs instantaneously after exposure, it is dangerous and compromits the whole body.

Anaphylaxis is characterized by its rapid instauration and the multisystemic manifestations.

There are different types of reactions to the allergen.
