Pollen blocker is used only for the treatment of allergic rhinitis. It can block the contact of nasal mucosa with various allergens, thus reducing the incidence of allergic symptoms and alleviating allergic reactions. As the nasal cavity is its main area of action, while it cannot protect against allergic rhinitis caused by other routes, its efficacy varies from person to person, mostly related to factors such as the coverage of the product and the retention time of the active ingredient in the nasal cavity.
Allergic rhinitis is a series of nasal allergic diseases with nasal itching, sneezing, nasal hypersecretion and swelling of nasal mucosa as the main symptoms after exposure to allergens that can cause allergic reactions in individuals with allergic constitution. Common allergens include inhalant allergens and ingested allergens. The former include: dust mites, pollen, artemisia, etc. The latter are mostly food and drugs. The latter are mostly food and drugs.
Pollen blocker mainly works in the nasal cavity to block inhalant allergens. After spraying the product into the nose, it forms a gel-like film that covers the surface of the nasal mucosa, cutting off the contact between inhalant allergens and allergic individuals, thus blocking the occurrence of allergic reactions.
Inadequate dosage or non-standardized method of spraying may prevent some patients from achieving the optimal effect of this therapy. Allergic reactions may also be triggered via the oropharyngeal mucosal route if the concentration and total amount of the allergenic substance is too high.
When it is necessary to use pollen blocker to treat allergic rhinitis, it is necessary to actively consult a doctor for systematic examination, to clarify the allergens, and then follow the doctor’s instructions for reasonable treatment and standardized operation.
