A pregnant woman with a cough can have an effect on the fetus. In particular, the fetus is more vulnerable up to 12 weeks. Because a violent cough can cause an increase in abdominal pressure, resulting in a lower placenta and the possibility of causing a fetal miscarriage, pregnant women during this period are still more cautious and restricted in the use of medication. If the cough is severe, you can take oral diphenhydramine hydrochloride tablets for cough suppression, and nebulize budesonide aerosol if available, or saline to moisten the airway and relieve the spasm state of the airway. Blood tests and C-reactive protein tests are also performed to understand the degree of inflammation, and anti-infective treatment is given in a timely manner. Patients should take rest, prevent exposure to cold, and avoid exposure to irritating odors such as oil and smoke to avoid aggravating the symptoms of cough.
