Try not to take cold medicine in early pregnancy. If you have serious cold symptoms or suffer from influenza and need to take cold medicine, you should use it reasonably under the guidance of your doctor. Broadly speaking, cold and flu medicines include cough suppressants, expectorants, antipyretics, Chinese patent medicines that clear away heat and remove toxins and diarrhea, antiviral medicines, and many other types of medicines. Some of these medicines will affect the healthy development of the fetus, which may lead to intrauterine fetal death or malformation of fetal development, and some medicines are prone to induce uterine contractions and cause miscarriage. In the case of mild symptoms of cold and flu with no complications, medication is generally not recommended, and intervention through lifestyle such as more rest, drinking more water, and eating a light diet is sufficient. If the symptoms are severe and medication is needed, you should follow the doctor’s instructions and try to choose medications that do not affect the development of the fetus. Traditional Chinese Medicine (TCM) has its own unique efficacy in treating colds and flu, and is more suitable for pregnant women.
