Coughing is a defense of the respiratory tract, and pregnant women often have coughing symptoms when they have a cold, so they should choose different treatment methods according to their condition and pregnancy. First of all, the treatment of a pregnant woman with a cold needs to take into account the severity of her condition. For pregnant women with mild colds, cough symptoms are often not obvious, and when there are no accompanying symptoms such as fever, shortness of breath and coughing sputum, conservative treatment is recommended. In the early stage of the cold, pregnant women are advised to drink more water, keep warm, eat a light diet, keep indoor air circulation and eat more vitamin-rich vegetables and fruits to help the body fight the cold. The common cold can usually heal itself in about a week, and the cough symptoms can be relieved. However, if a pregnant woman has an intolerable cough, appropriate cough suppressant or antipyretic or pungent warming drugs can be given to relieve the patient’s symptoms and shorten the course of the cold. The specific medication should be prescribed by the clinician after a face-to-face consultation, and should not be administered without authorization. However, for patients with severe colds, i.e. with fever, abdominal pain, coughing and other symptoms, they should be seen by the respiratory department or obstetrics department of the hospital as soon as possible and treated with oral medication under the guidance of the doctor to avoid serious effects on the pregnant woman and the fetus. Secondly, the treatment of a pregnant woman with a cold needs to take into account the pregnancy period of the pregnant woman. In early pregnancy (within 12 weeks), the fetus is unstable, so extra caution is needed when treating a cold and cough, and preventive and conservative measures should be taken at early detection to avoid oral medication. In the middle and late pregnancy, especially in the late pregnancy when the fetus is more stable, the indications for medication can be relaxed and some cough medicines and allopathic medicines can be used appropriately. Pregnant women should improve their immunity to avoid colds, as colds are a big challenge to both themselves and their fetus.
