Detailed explanation of the difference between long-term contraceptive pills and emergency contraceptive pills

There are many kinds of contraceptive measures and many kinds of drugs used. There is a big difference between long-term contraceptives and contraindicated contraceptives, and everyone needs to distinguish them clearly. Conventional contraceptives are relatively reliable and safe, while emergency contraceptives can easily cause hormonal disorders in the body.

1. Applicable Situations

Generally, conventional contraceptive pills are a contraceptive method that can be used for a long time. Under normal use, taking one pill a day for 21 consecutive days during each menstrual cycle can maintain a long-term and reliable contraceptive effect. It is more suitable for daily contraceptive use by healthy women of childbearing age.

As the name suggests, emergency contraceptive pills are a type of remedial contraceptive pills. They are suitable for women who suffer accidental injuries, have unprotected sex or other contraceptive methods fail. Generally, taking them within 72 hours afterwards can help avoid unwanted pregnancy. However, this type of contraceptive pill is not suitable for daily contraception, and it is best not to take it more than three times a year.

2. Mechanism of action

Conventional contraceptives work together with progestin and estrogen. As a safe and effective contraceptive method, they have been constantly improved. The estrogen content is gradually decreasing, and progestin is constantly being updated.

The main ingredient of emergency contraceptive pills is a large amount of progestin. The amount of hormone taken in once is equivalent to the content in 8-day conventional short-acting oral contraceptives. Therefore, large doses of exogenous hormones can easily cause endocrine disorders and changes in the menstrual cycle in women.
