If a pregnant woman has a bad cough, she often has an infection of the upper respiratory tract, and she should observe whether there is congestion and edema in the throat. It is advisable to take Chinese medicines with fewer side effects, such as Banlangen granules and Pu Di Lan anti-inflammatory oral liquid. It is good for relieving cough caused by inflammation and has very low side effects on the fetus. If the effect is not good for about three days, you need to check the blood count. If the blood test is accompanied by an increase in white blood cells, it indicates a combination of bacterial infection and requires antibiotics for treatment. If there is no allergy to penicillin, you can take oral amoxicillin for treatment. If there is allergy to amoxicillin, you can switch to azithromycin for anti-inflammatory treatment.
