What are the effects of emergency contraceptive pills?

The so-called emergency contraceptive pills are drugs that are used to terminate pregnancy during the regular contraceptive period because some pregnancy reactions occur due to the failure to play a normal contraceptive role. This type of contraceptive drug is generally used in unconventional contraceptive methods, and sometimes as a remedy for contraceptive failure. Generally, emergency contraceptive pills are used within 72 hours after sexual intercourse, so what are the effects of the pills?

Despite the continuous promotion of various contraceptive methods throughout the world, the incidence of induced abortions for unwanted pregnancies is still on the rise. The reason is

On the one hand, since there is no conventional contraceptive method that is absolutely effective, and the failure of contraceptive methods and the influence of the availability of contraceptive methods, unwanted pregnancies occur from time to time. On the other hand, due to the lack of any contraceptive methods, it is reported that about one-third to half of the unwanted pregnancies in artificial abortions in urban areas of my country occur after unprotected sexual intercourse. In order to reduce the rate of induced abortion, the international community began to explore effective emergency contraceptive methods in 1995. Emergency contraception refers to a remedial measure to prevent pregnancy after sexual intercourse without any contraceptive measures or the failure of contraceptive methods. The feasible ways are to place a copper IUD or take medicine.

Antiprogestin emergency contraceptive pills have the effects of terminating early pregnancy, resisting implantation, inducing menstruation and promoting cervical ripening. They compete with progesterone for receptors and achieve the effect of antagonizing progesterone. Taking different doses of mifepristone will achieve different effects: generally, taking 10 to 25 mg of mifepristone each time can be used for emergency contraception; taking 150 mg can terminate pregnancy within 49 days. If the use of this product fails to terminate early pregnancy, artificial abortion must be performed to terminate the pregnancy.

Taking emergency contraceptive pills has a great impact on the health of the body, so for women, if there is no unexpected pregnancy, try not to choose contraindicated contraceptive pills for contraception. Taking them may cause women to have irregular menstruation, abdominal pain, vomiting, etc., and even allergies in severe cases, so be sure to consult a doctor before taking them.
