Medication abortion is not usually recommended for 40 year old pregnant women. The abortion is not recommended for pregnant women over the age of 40, as the body functions are gradually declining and the endocrine hormone level is unstable. Therefore, it is not recommended for pregnant women over 40 years old to use drug abortion. 40 years old pregnant women are recommended to choose painless abortion surgery, in which the pregnant woman is put to sleep by injecting general anesthetic drugs and the pregnancy sac is directly sucked for abortion, which can reduce the chance of incomplete abortion and vaginal bleeding and is safer than drug abortion. After abortion, pay attention to rest and warmth, no bathing for 2 weeks, no sexual intercourse for 1 month, and pay attention to the hygiene care of perineum to avoid causing uterine cavity infection and affecting the repair of endometrium. Pay attention to vaginal bleeding and abdominal pain. If the bleeding lasts for more than 2 weeks or the bleeding volume gradually increases, accompanied by odor and lower abdominal pain, you should consult a doctor promptly.
