Pharyngitis can be divided into acute pharyngitis and chronic pharyngitis. If the acute pharyngitis is caused by viral infection or chronic pharyngitis, penicillin is not effective. If the acute pharyngitis is caused by bacterial infection, penicillin can be used to effectively fight the infection and reduce the state of congestion and edema of the pharyngeal mucosa. The common clinical use is amoxicillin injection, before using the drug is required to do a skin test. The specific type of pharyngitis can only be clarified by visiting a regular hospital. No matter what type of pharyngitis, it is recommended that patients should pay attention to a light diet, do not smoke, drink alcohol, and exercise to strengthen resistance during the course of the disease.
