Antihistamine drugs: common ones include cetirizine, loratadine, ketotifen, etc., which play an anti-allergic role by blocking the release of histamine. 2. Leukotriene inhibiting drugs: common drugs include montelukast, which is a leukotriene receptor antagonist and can reduce the occurrence of allergic symptoms. 3. Nasal glucocorticoids, but also the application of budesonide, mometasone furoate, fluticasone propionate nasal spray to reduce allergy symptoms. If allergic rhinitis has been diagnosed, you should consult a doctor in time to test for allergens. Try to avoid contact with allergens in your life.
