Amoxicillin is an antimicrobial agent that can only be useful for acute pharyngitis combined with bacterial infection, but not for chronic pharyngitis, so do not use it for a long time. In the case of acute pharyngitis, it is important to drink more water and rest while using these drugs, rinse your mouth with mouthwash and maintain oral hygiene. If the systemic symptoms are severe, the drugs should be administered through the intravenous route, and the appropriate use of glucocorticoids can control the infection, reduce edema, and facilitate the recovery of the disease. For chronic pharyngitis, treatment is mainly based on removing the causes of the disease, to reduce the consumption of spicy and irritating food, quit smoking and alcohol, avoid exposure to dust and irritating gases, while using tablets with Chinese herbal ingredients. If there are obvious systemic diseases, such as diabetes, hypothyroidism, etc., the primary disease should be actively treated.
