When a woman catches a cold during pregnancy, it is best not to take medicines. Most of the cold medicines are compound preparations containing a variety of ingredients that may adversely affect the fetus. If it is only a mild cold with a runny nose, it is recommended that pregnant women should pay more attention to rest, drink more warm water to promote metabolism, which is conducive to the recovery of the disease, eat more fresh vegetables and fruits, and supplement with nutritious substances, such as beef, eggs, milk, etc., and do not eat spicy and stimulating foods. If there are symptoms of respiratory tract infection such as strong cough and fever, you must go to a regular hospital for examination to find out what causes colds, such as viral infection, bacterial infection, mycoplasma infection, etc., and use medication under the guidance of a professional doctor, and choose medications that have fewer side effects on the pregnant woman and the fetus, and remember not to use medication on your own.
