After eating betel nut, the patient feels that his throat is blocked, probably because he chewed betel nut for a long time and in a large amount, which is particularly easy to cause the betel nut juice to irritate the patient's throat mucosa with congestion and inflammation, so the patient will feel that his throat is blocked. We must deal with it actively, and advise patients not to chew betel nut for the time being. At the same time, we should spray watermelon frost spray in the throat, or take Pudilan anti-inflammatory oral liquid orally and add Ganju Bingmei tablets, which can effectively reduce the foreign body sensation in the throat of patients. However, if the patient still feels obvious foreign body sensation after eating, it is best to go to the hospital for examination, and antibiotics may be added to diminish inflammation, and the effect will be better. Azithromycin dispersible tablets are commonly used in clinic, and it is necessary to know whether there is any allergic history to azithromycin before taking the medicine.
