Pregnant women with cough and bronchitis need to be given a combination of herbal and western medicine. Depending on the condition of the pregnant woman’s cough and whether the blood test is accompanied by bacterial or viral infection, antibacterial treatment and antiviral drugs are given respectively. Considering the safety of pregnant women, general antibiotics are mainly given as penicillin and cephalosporin antibiotics. These antibiotics have less effect on pregnant women and fetuses, so they can be used regularly for about a week, and then it will be recommended whether to continue using them according to the situation. Chinese medicine treatment for bronchitis and cough in pregnant women mainly requires identification of wind-cold or wind-heat. If the cough is wind-cold, we need to give the cough to promote the lung and relieve the symptoms, dispel the cold and stop the cough, including Tongxuan Li-Lung Pill and Ma Heng Gan Shi Granules. If it is a wind-heat cough, you can give wind and clear heat, resolve phlegm and relieve cough, including Snake Bile and Chuanbei Liquid and Lung Power Cough Compound, which are relatively safe and have a better effect on cough and bronchitis in pregnant women.
