Difference
Emergency contraceptive pills are two types of contraceptive pills with very different effect mechanisms and applicable groups. Conventional short-acting oral contraceptive pills are safe, effective, and comfortable. They are suitable for all healthy women of childbearing age who need contraception. They are one of the most reliable conventional contraceptive methods. Emergency contraceptive pills are used as contraceptive pills after failure to prevent pregnancy or failure. Compensatory contraceptive methods.
Applicable situations vary
Conventional short-acting oral contraceptive pills are a contraceptive method that can be used for a long time. When used correctly, one tablet a day and taken continuously for several days during each menstrual cycle can be used. Adhere to the reliable contraceptive effect and easily avoid the confusion of unplanned pregnancy. It is suitable for daily contraceptive use by healthy women of childbearing age.
Emergency contraception is a compensatory contraceptive that is suitable for women who suffer accidental injuries, have unprotected sex, or fail other contraceptive methods (such as condoms accidentally breaking). They can be used in the future. Take it within hours to avoid unwanted pregnancy, but it is not suitable as a regular contraceptive method.
The mechanism of effect is different
Conventional short-acting oral contraceptive pills work together with progesterone and estrogen. As a safe and reliable contraceptive method, conventional short-acting oral contraceptives have been continuously improved, the estrogen content is gradually reduced, and the progesterone is also constantly updated. The progesterone component in new oral contraceptive pills is now very close to human progesterone, and it can also provide women with additional benefits in addition to contraception, such as reducing edema and preventing ovarian cancer.
The main ingredient of the most common emergency contraceptive pill on the market is usually a large amount of progesterone. The amount of hormone taken in at one time is equivalent to the content in regular short-acting oral contraceptives. Therefore, it is recommended that emergency contraceptive pills be used no more than three times a year and no more than once a month.
Contraceptive effects are different
Emergency contraceptive pills mainly compensate for future needs. The contraceptive effectiveness rate is about 10%, which can reduce the possibility of unwanted pregnancy. As long as the conventional short-acting oral contraceptive pills are taken accurately, the contraceptive effect is very reliable, and the contraceptive effectiveness rate can reach above. In order to protect yourself from the damage of an unexpected pregnancy, it is wise to be fully prepared in advance.
Clinical Application Although various contraceptive methods are continuously promoted around the world, the incidence of abortion of unwanted pregnancy is still increasing. On the one hand, there is no conventional contraceptive method that is necessarily effective. In addition, due to the failure of contraceptive methods and the availability of contraceptive methods, unintended pregnancies occur from time to time. On the other hand, because no contraceptive method is used, it is reported that about one-third to half of unintended pregnancies in urban abortions in my country occur after unprotected sexual intercourse. In order to reduce the abortion rate, the world began to explore effective emergency contraceptive methods in 2009. Emergency contraception refers to a compensatory method to avoid pregnancy after sexual intercourse without any contraceptive method or contraceptive method failure. The feasible ways are to place a copper belt or take drug.
