Patients with particularly strong cough after tonsillitis are advised to apply anti-inflammatory drugs to reduce inflammation, such as amoxicillin, cefradine, penicillin and so on. At the same time, you can use cough suppressant drugs, such as Lung Ning granules, Serpentine Chuanbei capsule or compound methanamine capsule have good clinical effect. If the patient has a lot of mucous phlegm, it is best to take oral aminoglutethimide hydrochloride, and you can also do nebulized inhalation treatment with beclomethasone propionate suspension, which are clinically very effective. Normal active treatment should improve the patient’s condition in a week or so, but if the patient still coughs badly, consider going to the hospital for further consultation and taking a CT of the lungs to clarify whether there is a combination of bronchitis or pneumonia, and consider going to the respiratory department for further consultation.
