Clear nasal discharge from one nostril, accompanied by sneezing, is considered to be caused by allergic rhinitis, also known as allergic rhinitis. In terms of treatment, it is recommended that topical application of nasal spray hormones, such as endosulpride or co-sulpride, can be used. If the patient is more acute and the symptoms are more serious, you can also use some anti-allergy drugs, such as dexloratadine tablets taken orally. If the disease is recurrent and seasonal, it is recommended to use the drugs before the onset of the disease, which can effectively control the disease, and then choose some drugs to regulate the immunity of the body as appropriate, such as transfer factor oral solution, or Stryker intramuscular injection, which is also helpful for the recovery of the disease.
