Why can eat Yu Ting ectopic pregnancy?
summary
Yuting has both advantages and disadvantages. Every woman should have a certain understanding of whether levonorgestrel tablets, the emergency contraceptive represented by "Yuting", can cause ectopic pregnancy. However, in life, many people don't know much about this early symptom, and their condition is quite serious when they get sick. A few days ago, the State Food and Drug Administration added the content of "vigilance against the existence of ectopic pregnancy" to the item of "adverse reactions" in the revision of the instructions of levonorgestrel tablets. This means that users of levonorgestrel tablets should pay attention to the risk of ectopic pregnancy. Now I'd like to share with you why Yuting has ectopic pregnancy?.
Why can eat Yu Ting ectopic pregnancy?
First: "adverse reactions" add ectopic pregnancy content. According to the monitoring results of adverse reactions, in order to control the risk of drug use, the State Food and Drug Administration decided to revise the model manual of levonorgestrel tablets over-the-counter drug to further improve the contents of "adverse reactions", "precautions" and "contraindications". The reporter saw from the notice of the State Food and drug administration that the number of "adverse reactions", "precautions" and "contraindications" increased to 3, 11 and 2 respectively. Compared with the previous "Yuting" instructions, the reporter found that the new content of "adverse drug reactions" is: "menstruation changes can be seen, most of which are manifested in the early or delayed menstruation in the month of taking medicine."“ There may be abnormal uterine bleeding. If the bleeding can not disappear, we should go to the hospital in time to guard against the existence of ectopic pregnancy“ Contraindications "more" known or suspected pregnancy prohibited "project“ Caution "also mentions the risk of ectopic pregnancy, and reminds:" if irregular uterine bleeding or severe lower abdominal pain occurs about 3-5 weeks after taking the medicine, you should see a doctor in time to eliminate ectopic pregnancy. ".
Second: the emergency contraceptive was abused. The reporter visited some local pharmacies and found that most of the drug instructions of levonorgestrel tablets were not updated. The sales staff of pharmacies also denied whether there was any risk of ectopic pregnancy after use. Earlier, Tianya community on an article called "Yuting, how much more ectopic pregnancy to create?" More than half of the more than 30 ectopic pregnancy patients contacted during their internship in obstetrics and Gynecology had taken Yuting. Because of advertising, emergency contraceptives such as "Yuting" have been abused, and experts have constantly called for drug instructions to be modified and improved.
Third: Shen Huimin, deputy chief gynecologist of the Third Affiliated Hospital of Sun Yat sen University, who has many years of clinical experience, told reporters that whether drug users have the risk of ectopic pregnancy mainly depends on whether they have ovulated. The first mechanism of levonorgestrel is to inhibit ovulation, change the consistency of cervical mucus, prevent sperm from passing through, and make the endometrium appear atypical secretory phase, It is not conducive to the implantation of pregnant eggs, so as to achieve the purpose of contraception. But once ovulation is not inhibited, the movement of the fallopian tube is affected by drugs, the fertilized egg road is blocked, can not normally enter the uterus, will lead to ectopic pregnancy. Because the fertilized egg is sent to the uterus after tubal pregnancy, it depends on the swing of the tubal cilia and the peristalsis of the smooth muscle.
matters needing attention
The reporter learned from some front-line doctors that most of the adverse reactions of people who use levonorgestrel tablets are menstrual disorders, but they are not mentioned in the old version of drug instructions.
