To conduct the test, drops of allergens (household, food, pollen, epidermal, etc.) are applied to the skin of the forearm or back. Two control solutions are mandatory: histamine (positive control) and 0.9% sodium chloride (negative control). Then, through drops with a special device - prik - the allergen is introduced 1 mm deep into the skin and after 10-15 minutes it is possible to understand by the reaction of the skin whether the patient has this or that sensitization. A positive response in the prick test is the presence of a blister of 3 mm or more.
With vasomotor rhinitis, the vessels of the nose become extremely sensitive and dilated, which leads to swelling, nasal congestion and impaired nasal breathing. Unlike allergic rhinitis, the development of sildenafil pills rhinitis is not associated with any allergen. Most often it leads to: the use of vasoconstrictor drops (decongestants); hormonal changes (eg, during pregnancy, puberty, endocrine diseases); irritants (hot or spicy food, cold air); stress. Symptoms characteristic of allergic rhinitis: itching in the nose, frequent sneezing, copious watery discharge from the nose, itching, redness and swelling of the eyes are much less common with vasomotor rhinitis.
Treatment of patients suffering from allergic rhinitis should be prescribed taking into account the individual characteristics of the organism. It will include: Antihistamines for systemic and local action. Aimed at suppressing the action of free histamine.
