For cough caused by rhinitis, the medications available are tretinoin nasal spray, which can be sprayed on the nose to reduce congestion and swelling of the nasal mucosa and reduce the secretion of the nasal mucosa. You can also take eucalyptus soft capsules orally, and if necessary, add proprietary Chinese medicines, such as patchouli bile tablets and chamomile tablets. Cough caused by rhinitis is mostly due to nasal secretions flowing from the nasopharynx to the pharynx, which stimulates the mucous membrane of the pharynx, causing itching of the mucous membrane of the pharynx and thus causing cough. Rhinitis is mostly caused by recurrent acute rhinitis, which can manifest as nasal congestion, runny nose, accompanied by decreased sense of smell, etc. When examined, the nasal mucosa is congested and swollen, and the inferior turbinate can be enlarged.
