What is systemic allergic reaction?
The substances causing allergic reactions are called allergens, such as pollen, indoor dust, fish, shrimp, milk, eggs, penicillin, sulfanilamide, quinine, etc. When some people come into contact with allergens, they are stimulated by allergens and produce antibodies by effector B cells
Some antibodies are adsorbed on the surface of some cells in skin, respiratory tract or digestive tract mucosa and blood. When the same allergen enters the body again, it will combine with the corresponding antibody adsorbed on the cell surface, which will make the above cells release histamine and other substances, causing capillary dilatation, vascular wall permeability enhancement, smooth muscle contraction and gland secretion increase.
In case of wind, cold, heat, spicy, sun, excitement, hand grasping, pressure, seafood, cosmetics, biting, dust, pollen, cold water, all kinds of fake and inferior cosmetics or cosmetics not suitable for oneself
matters needing attention
It is not suitable to take a certain antiallergic drug in a long-term and large dose, which is easy to cause drug resistance. It is generally appropriate to take it for 2-3 months, otherwise the efficacy will decline, but it will not produce dependence. For example, some antiallergic drugs will stimulate the satiety nerve of the body, produce obesity effect, and recover after a few days of withdrawal. Take different kinds of anti allergic drugs in turn.
