Bronchitis during breastfeeding should be treated promptly with antibacterial drugs in the presence of bacterial infection. For example, if the sputum is yellow, you can choose cephalosporins to be taken orally. If there is no obvious bacterial infection, the use of antibacterial drugs is not recommended. If there is a cough without sputum or little sputum, oral medication to stop the cough is not recommended during breastfeeding. You can do nebulization, such as nebulization with budesonide, or take oral Chinese medicine like acute syrup. If the cough has phlegm and it is not easy to cough it up, it is recommended to use oral treatment of children’s aminoglutethimide hydrochloride to reduce phlegm. It is necessary to take more rest and drink more water, avoid exertion, enhance physical fitness and improve the living hygiene environment. Pay attention to ventilation at home to prevent air pollution, and also remove lesions in the nose, throat and other parts of the body.
