Emergency contraceptives, as a talisman to deal with the aftermath of sex and rain, will naturally become an area where crazy men and women are in urgent need of popular science.
Yuting will not lead to ectopic pregnancy? Can I have the baby I was pregnant with after eating Yuting? Also, in the first half of the year, people have already eaten Yuting once on Western Valentine’s Day. Can they still eat it this year? … …
Let’s listen to Jing (Canadian Registered Pharmacist) ‘s professional views.
First of all, the emergency contraceptives mentioned in this article refer specifically to progesterone drugs, namely Yuting. Misoprostol belongs to drug flow drugs, and its essential mechanism of action is different from progesterone drugs. Foreign countries are not used as emergency contraceptives (can be used as abortion drugs through prescriptions).
Emergency contraceptives can only be used twice a year?
For a long time, I have been very unable to understand why the emergency contraception pill is regarded as a scourge, and even heard constant exhortations from medical workers: never eat more. As for the consequences of taking more what, the light ones have irregular menstruation and the heavy ones are infertile. It really scares people to death.
However, no one has ever provided any evidence to support this scary statement. Moreover, I have never heard this statement only in the Chinese community. In the course of my study and practice in Canada, I have never heard of the requirement of the frequency of emergency contraception use.
In my experience, developed countries generally pay great attention to drug safety. If the emergency contraception pill really has such a great impact, it cannot be without warning.
Today, I saw a scarf issued by the official account of the fruit shell intellectual community, and even warned that emergency contraceptives should not be used more than twice a year.
Such a popular science account uses this unsubstantiated statement, and I can’t sit still. I searched the frequency requirement for using emergency contraceptives. I found the following two articles:
http://www.rhtp.org/contraception/emergency/documents/RepeatUseofEC.pdf
http://www.ncbi.nlm.nih.gov/pubmed/15033411
To sum up, the frequency of using emergency contraceptives is: as often as needed. There is no requirement for frequency.
Studies have explored the possibility of using Plan B (Levonorgestrol) as a routine contraceptive pill. More than 8,800 women took more than 2-4 times the dose of the normal emergency contraceptive pill, with an average of 6-8 months. There were no serious side effects. See the first article for details.
The World Health Organization said there was no known risk of repeated use of emergency contraceptives.

The article also mentioned the opinions of ACOG and ARHP, but it seems that the connection has failed, so I will not post it. The authoritative official agencies have not heard of any one that supports the non-reuse of emergency contraceptives.
In short, as far as I know, there is no evidence to support that frequent use of emergency contraceptives will have any long-term adverse consequences.
Why can’t emergency contraception be used as a routine contraceptive?
First, it is very simple, because the effect is not good. The failure rate of emergency contraceptives is much higher than that of conventional contraceptives, such as condoms and conventional contraceptives. Post-event remedial measures, of course, are not as good as preparation in advance. Therefore, if emergency contraceptives are used for contraception, the chances of winning the recruitment are greatly improved.
Second, in general, the progesterone content in emergency contraceptives is higher than that in conventional contraceptives. Lead to more side effects-not long-term adverse consequences, But short-term nausea, irregular menstrual period and so on (generally will disappear after stopping drugs). Although there are no serious consequences of what, it is easy to cause psychological pressure to girls, especially menstrual period will sometimes be delayed, which is a little worse for girls who are already worried about pregnancy, so it is not suitable as a routine contraceptive method.
Third, I don’t know whether this is applicable in China, but if you have bought (or sold) emergency contraceptives in Canada, it is really expensive! Two small pills, almost 50 dollars! The insurance is not reported yet (because it is OTC). If you eat it every day, you will not be allowed to go bankrupt! Relatively speaking, the average amount of conventional contraceptives is less than 20 yuan a month. And the insurance is usually reported (because it is a prescription drug). The University of Toronto clinic even provides it to students free of charge. Condoms are also cheaper than this. Therefore, it is not necessary to spend money on this drug, which is not effective and expensive.
So in all respects, If you don’t want to get pregnant, There are many options available, Whether physically or chemically, there is really no reason why emergency contraception should be used frequently. Generally speaking, it is most reasonable to use emergency contraception as a remedy for routine contraceptive failure (such as a broken condom-this is the most common reason). But this is not the reason why eating too much will cause infertility.
I guess this scary method is to prevent girls from belittling contraception. Preventing unprotected sex, But to scare people with this unsubstantiated statement, It is inevitable that it will backfire. You know, if you really have the possibility of pregnancy, and girls absolutely can’t have children, emergency contraceptives are far better than abortion, even if this is the fifth time this year to eat. Because the side effects of abortion and long-term adverse consequences are much larger, the formation of habitual abortion can really be infertile after yo.
On balance, I don’t know whether what can hold up the reason to prevent taking emergency contraceptives. Moreover, taking emergency contraceptives is a race against time. The better the effect is when it is used at the earliest. Therefore, girls should buy and eat it in the first place. Therefore, their correct understanding of emergency contraceptives is especially important.
Finally, of course, I am not encouraging people to use emergency contraceptives casually. I have already said the reasons why emergency contraceptives should not be used as routine contraceptives. The last thing I want to see is that girls have to miscarry because they do not take them because they abide by the unsubstantiated statement that they cannot take them more than twice a year. I hope this An article can help.
