1) Nausea: After taking it, the symptoms of nausea usually last less than 24 hours.
2) Vomiting: Taking medicine together with food or before going to bed can reduce the incidence of nausea and vomiting. If you vomit within 1 hour after taking emergency contraception, you should take 1 time as soon as possible. Enteric-coated contraceptives do not dissolve until they reach the intestine, so there is no need to refuse.
3) Irregular uterine bleeding: Some women will have a little bleeding after taking the medicine, and generally do not need to deal with it, but let the users know about this situation and do a good job of consultation and education before and after taking the medicine.
4) Menstrual changes: Most women will have menstrual cramps on time, and some women will have their menstruation earlier or later. If menstruation is delayed for one week, urine pregnancy test should be done to determine whether it is an emergency contraceptive failure.
5) Change of ovulation period: Taking emergency contraception will affect menstrual cycle. After that, women should try their best to use efficient contraceptive methods, and don't take the risk of using emergency contraception or unscientific contraceptive methods such as safe period and coitus interruptus, which will seriously lead to infertility.
6) Others: breast pain, headache, dizziness, fatigue, etc. These symptoms are generally mild and last no more than 24 hours. Patients with breast pain and severe headache can be treated with aspirin or other painkillers.
mistaken idea
Many people have some misunderstandings about emergency contraception, and they often dare not use it, which leads to unexpected pregnancy, thus causing harm to their health. Therefore, we should treat emergency contraception scientifically and avoid misunderstandings:
Myth 1: It will affect menstruation.
Many people think that emergency contraception will affect menstruation, but it is not. Take Yuting as an example, it is a simple progestin, and the dose is very low, so it has almost no effect on menstruation. However, due to individual differences, some people will have withdrawal bleeding (similar to menstruation) after taking Yuting contraception successfully. If the amount of bleeding is similar to that of normal menstruation, it can be regarded as a menstruation, but it is a normal phenomenon, so you don't have to worry, and you can recover on your own. However, if you take it many times in a short period of time, it may cause menstrual disorder and reduce the success rate of contraception.
Myth 2: It has an impact on the fetus.
Because the emergency contraceptive Yuting is a simple progestin, and the dosage is very small, it is very safe and will not cause adverse effects on the fetus. Moreover, research shows that some women take Yuting without knowing the pregnancy, which does not increase birth defects or other problems.
Myth 3: Contraception will fail.
The contraceptive success rate of emergency contraceptives is 98%, and that of New Si Nuo levonorgestrel dropping pills is as high as 99.9%. Know how to take it correctly and then use contraception:
1, within 72 hours after the event, take 2 new Si Nuo levonorgestrel dropping pills orally once; Or take 1 capsule for the first time, and take the second capsule every 12 hours. The earlier you take the medicine, the better the effect of preventing pregnancy.
2, emergency contraception should follow the principle of one remedy at a time, it only works for the last unprotected sex life or contraceptive failure, and has no good contraceptive effect for the next unprotected sex life or contraceptive failure, so as long as there is an unprotected sex life or contraceptive failure, it is necessary to take the new Si Nuo levonorgestrel dropping pills in time to avoid unintended pregnancy.
Difference between prescription and over-the-counter prescription
Emergency contraceptives are generally divided into prescription and over-the-counter drugs, such as New Si Nuo levonorgestrel dropping pills, which are over-the-counter drugs, while Misafenone is a prescription drug. The main difference is that over-the-counter drugs (OTC) refer to drugs that can be bought in pharmacies without holding a doctor's prescription, which are over-the-counter. On the contrary, it is a prescription drug. Over-the-counter drugs are generally slowly transformed from the original prescription drugs. After a long period of clinical practice, the identification of drug properties is very safe and reliable, and it can be converted into over-the-counter drugs without the supervision of doctors, when patients will not cause other dangers after using them. Therefore, over-the-counter emergency contraceptives such as New Si Nuo levonorgestrel dropping pills are very safe.
Precautions, medication instructions
(1) emergency contraception can only have contraceptive effect after the first one-time life, and there can be no unprotected sex after taking the medicine.
⑵ A small amount of vaginal bleeding after taking medicine is not a sign of contraceptive success. If there is no menstrual bleeding, you should go to the hospital as soon as possible.
(3) If vomiting occurs within 1 hour after taking the medicine, you should take it as soon as possible 1 time.
(4) Emergency contraceptives can only be used occasionally, and cannot replace conventional contraceptive methods.
5] pregnant women are forbidden to use emergency contraception, because emergency contraception has no abortion effect on established pregnancy.
After unprotected sex, the earlier you take the medicine, the better the effect of preventing unwanted pregnancy.
Contraceptives and menstruation
Emergency contraceptives can lead to irregular menstruation in women. If they are taken in the first half of the menstrual cycle, the side effects of emergency contraceptives may interfere with women's menstruation and are prone to vaginal bleeding. If taken in the second half of the menstrual cycle, it will have little interference with women's menstruation. If the amount of bleeding is similar to the amount of menstruation at ordinary times, it can be regarded as a menstruation.
Premature menstruation: Hemorrhage after emergency contraception is clinically called withdrawal hemorrhage. In fact, this kind of bleeding can't generally be considered as menstrual cramps. If it is taken in the first half of the menstrual cycle, it may interfere with women's menstruation and is prone to vaginal bleeding; Taking it in the second half of the menstrual cycle has little interference with women's menstruation. If the amount of bleeding is similar to the amount of menstruation at ordinary times, it can be regarded as a menstruation, and conventional contraceptive methods should be taken immediately after the bleeding is clean. If the amount of bleeding is small, you don't need to do anything, but you still need to pay attention to contraception until the next menstrual cramp.
Taboo crowd
Eight types of women should not take it:
1. Patients with major diseases
Because hormone drugs are metabolized in the liver and excreted from the kidney, the use of drugs will increase the burden of liver and kidney function, so patients with acute and chronic hepatitis or nephritis should not be used.
2. Patients with hematological diseases and endocrine diseases
Contraceptive pills can make blood coagulation hyperfunction, increase the risk of thrombosis, increase blood sugar and affect thyroid function, so patients with various blood diseases, thrombotic diseases and endocrine diseases such as diabetes and hyperthyroidism should avoid application.
3. Patients with gynecological tumors
Because gynecological tumors and breast diseases are mostly hormone-dependent diseases, taking contraceptives containing estrogen and progesterone can aggravate the condition and should be banned.
4. Mental patients
Mental patients who can't take care of themselves may take the wrong medicine by mistake, which may have adverse consequences.
5. People with scanty menstruation
Birth control pills may further reduce menstruation.
6. Persons over the age of 45
During this period, the hormone level fluctuated greatly, so it is generally not suitable to use contraceptives for contraception.
7. Women over 35 who smoke.
It should not be taken for a long time to avoid premature ovarian failure.
8. Lactating women
Contraceptive pills can inhibit milk secretion and affect the development of newborns through milk secretion, so lactating women can't use them.
