Pharmacist Natalia Timokhina points out that barrier nasal sprays reduce the contact of allergens with the mucous membrane, which helps to relieve sneezing, itching, nasal congestion, and other symptoms.
She says: "Barrier nasal sprays are one option for preventing allergy symptoms. Unlike vasoconstrictor or hormonal medications, they work differently. After being sprayed, these products coat the nasal mucosa with a thin, protective layer that acts as a filter, preventing pollen particles, house dust, or other irritants from settling on the walls of the nasal passages. Some sprays also contain plant extracts and essential oils, which soothe the mucosa and reduce inflammation."
However, it's important to understand that nasal barrier sprays don't treat allergies or eliminate their cause. They only reduce the likelihood of allergens coming into contact with the mucous membranes.
She says: "For effective protection, it is preferable to spray the product beforehand, before exposure to allergens. For example, before going out during pollen season. Protective sprays have many advantages that make them popular to use - they are not absorbed into the bloodstream and are not addictive, so they can be used long-term. Also, the small container can always be carried for use when needed, for example, before going for a walk in the park or traveling out of town."
The pharmacist emphasizes that protective sprays cannot be considered a universal treatment, as their effectiveness may depend on individual characteristics and the type of allergen. Therefore, before using them, a doctor should be consulted, who will take into account individual needs and body characteristics.
