Nasal itching accompanied by sneezing and runny nose is usually seen in allergic rhinitis, which is a nasal-related condition caused by inhalation of allergens in the nose. Allergens often include dust, pollen, mites or cold and warm air irritation. In terms of treatment, allergic rhinitis requires firstly avoiding allergens, wearing a mask when going out, keeping the house clean and removing mites regularly. Oral anti-allergy medications, such as loratadine, are needed, as well as nasal coleus, endosulfan or beclomethasone propionate nasal aerosol. It takes about one month to enter remission. After entering remission, the patient needs to exercise and improve immunity and resistance in order to be completely cured.
