Generally, viral colds are troublesome during pregnancy, and this is not a time to be treated with antiviral drugs. Anti-viral drugs have some effect on the fetus, but relatively speaking, if it is late in pregnancy, the effect will be small. It is recommended to maintain a light and easy-to-digest diet, pay attention to rest, drink more water appropriately, maintain a suitable room temperature, pay attention to the hygiene of the environment and the pregnant woman’s own hygiene, etc. Try to avoid going to crowded places, try to keep the people in contact in a healthy condition, avoid contacting people and things with infectious diseases, especially pets, which are prohibited from direct or indirect contact with pregnant women. If the condition is serious and the degree of harm is much greater than the side effects of taking drugs to the fetus and the mother, use penicillin as well as other drugs under the guidance of the doctor and carry out observation and treatment.
