There is seasonal allergic rhinitis, which causes nasal congestion, itchy nose, eyes, mouth, ears, sneezing, runny nose, headache, sleep disorder and other symptoms, and in severe cases, bronchial asthma and breathing difficulties. How should I treat it now? Suggestions: 1. Start taking oral antihistamines such as loratadine, cetirizine and epalmatine. 2, nasal spray glucocorticosteroids (such as budesonide, nexium, coleus), 3, nasal spray antihistamines (such as Acesaprine) 4, leukotriene antagonists (such as montelukast sodium) 5, with asthma can be added to the inhalation of the Scholastic. 6.Auxiliary Chinese medicine. For milder symptoms: 1, 2, 3 alternately. For moderate cases, any combination of 1, 2, 3 can be used. The purpose is to prevent drug tolerance. For the more severe symptoms, it is recommended that: first 1 + 2 x 3 x 6, second 1 x 2 x 3 x 4 + 6 be used simultaneously. After the symptoms are controlled and stabilized, the drug treatment can be reduced. How to reduce it? Take the first option: 6 drugs to stop, 1, 2, 3 any 2 combinations of use, so reduce a drug, symptom control and stability, can 1, 2, 3 alternate use, so reduce another drug, if still able to control stable symptoms, available 1 after the interval of a day with 2, interval of a day with 3, so that small doses of a variety of drugs to maintain the use of symptom control and stability, to the winter natural discontinuation of drugs. Note that during this process can not control the symptoms to return to the previous treatment plan. Next year, in the summer, usually in mid-volley, the above method is used in reverse, i.e., small doses of multiple drugs are maintained until winter, so that the patient does not develop or the symptoms are mild. This is called prophylaxis. Of course, it is best to get away from allergens, that is, if you have the conditions, you can be a migratory bird, now move to the south (such as Hainan) to return after the season. Remember that if you return in the middle of the season, you must take medication in advance, otherwise you will develop the disease. Then there is desensitization treatment. That is, allergens are gradually desensitized (subcutaneous injection or sublingual) for 2 to 3 years after detection. This method is advocated. However, there are many people who cannot find allergens or do not have antigenic reagents. Then there is the poor medical compliance of patients, sometimes difficult to adhere to. Preventive treatment is emphasized here, otherwise this year is heavier than last year, next year is heavier than this year, and finally the drug is difficult to control. The timing of preventive treatment is: from spring to summer when the willow tree is sprouting, and from the peak of summer to winter in autumn. Generally, the medication is used two weeks before the onset of the disease.
