Are birth control pills effective for 72 hours?

There are many types of contraceptive pills. Their main function is to solve the problem of emergency contraception after men and women have sex because they did not take contraceptive measures. Some contraceptive pills can be taken in advance, and some can be delayed. There are many types of contraceptive pills. How long do they last? Let's take a look at some relevant knowledge about birth control pills.

As a post-emergency contraceptive measure, emergency contraceptive pills have certain requirements for the time of taking them. Generally speaking, the earlier you take the medicine, the better the contraceptive effect will be. Studies have shown that the medicine is still effective if taken within 100-120 hours after sex, but our clinicians still recommend taking the medicine within 72 hours, which is safer and more reliable, and the contraceptive effect is relatively guaranteed.

Unfortunately, although I have been working in Chunyu Clinic for many years, I often meet some young girls who are inexperienced and still have many misunderstandings about taking emergency contraception. I once saw a 17-year-old girl who took emergency contraceptive pills three times in three days. Many girls take emergency contraceptive pills as regular contraceptive pills, which often leads to contraceptive failure, menstrual abnormalities, and menstrual disorders.

at present

The success rate of emergency contraception is 98%, and the failure rate is about 1.4%. In fact, I think this data has some errors. In fact, in life, examples of emergency contraceptive failure are not uncommon. The main reasons for contraceptive failure may be failure to take the medicine within the prescribed time, or taking it multiple times in a short period of time, which reduces the contraceptive efficiency of emergency contraceptive pills. Some women also think that taking emergency contraceptive pills is a one-time solution. They can have sex as much as they want within 72 hours after taking the emergency contraceptive pills without taking any other contraceptive measures. These are all misunderstandings about oral emergency contraceptive pills, which also invisibly increase the failure rate of emergency contraceptive pills.

In short, emergency contraceptive pills are not universal contraceptives. They may be effective when used temporarily, but they may fail if used frequently. Therefore, young girls, be cautious when taking the pills and don't forget the 72-hour time limit.
