Postinor: clear instructions for use. What are the consequences of taking "postinor"

The choice of modern contraceptives is great. Their actions boil down to two principles. Some need to be taken constantly, others - once and only in emergency cases. Postinor refers to emergency drugs. The drug reduces the possibility of an unplanned pregnancy by 5-10 percent.

There is an opinion that postinor is a means of aggressive influence. Indeed, if the drug is used incorrectly, health problems can occur. It cannot be used continuously. In addition, before use, be sure to read the instructions. Postinor has contraindications and side effects. The drug is released in pharmacies by prescription. Therefore, it is better to consult a gynecologist in advance.

The consequences of taking postinor

The consequences of taking postinor may not be dangerous to health if taken too often. Some doctors recommend using it no more than 1 time in 3 months. Others - no more than 1 time per month. Abuse can lead to menstrual irregularities and hormonal imbalance. This is due to the active substance of the drug. It contains a concentrated dose of hormones. If there are no negative consequences of taking it, you can not consult a doctor. Otherwise, a consultation with a gynecologist is required. Untimely diagnosis and treatment of the consequences of the use of prostinor can lead to many female diseases.

Pregnancy after postinor

1. If you have taken the pill within 72 hours of unprotected intercourse, pregnancy after postinor is unlikely. In the first 24 hours, its effectiveness reaches 95 percent.
2. If, nevertheless, conception has occurred, then the consequences can be negative. There is a possibility of changes in the structure of the uterus, the occurrence of a miscarriage, etc.
3. But if the pregnancy persists, do not worry. The dangers of the influence of prostinor on the fetus have not been identified by physicians.

Menstruation after postinor: features

Menstruation after postinor can begin in a timely manner. Cycle failure is also possible. It may return to normal after some time. The instructions for the drug say that it can only be used by women with regular periods. In order to avoid serious consequences after application, you should consult a gynecologist.

Postinor action

Pastinor pack contains two tablets. First you need to take one, then after some time - another (after 12-16 hours). Some doctors recommend drinking two at once. It often happens that women forget to take the second dose of the drug.

The remedy works as follows: the active substance levonorgestrel, an artificially created hormone, slows down the movement of the egg to the uterus. If she nevertheless reached the goal, she does not allow to attach to the wall. This is due to a change in the surface of the uterus due to the action of the drug.

The effectiveness of contraceptives most of all depends on how quickly you take the pill. Should not be tightened. After 72 hours, the chance of getting pregnant will increase. The effectiveness of postinor may decrease due to the use of other drugs: for tuberculosis, for HIV therapy, for epilepsy and fungus. In addition, a similar result is achieved by combining the drug and drugs containing St. John's wort.

Bleeding after postinor

Many confuse bleeding after postinor with the onset of menstruation. Actually it is not. The action of the contraceptive may cause acyclic discharge. They look like very scanty menstrual flow. Bleeding may last for 1-2 days. A delay of up to 5 days is considered normal. If the period is longer, you should consult a doctor. There may be pregnancy or hormonal failure.

Postinor: side effects

Many after taking postinor feel nausea, pain in the lower abdomen, general malaise and weakness. This does not mean that all women should have such a reaction. Side effects may not appear

Before using the drug, you should familiarize yourself with the contraindications. Postinor should not be taken in adolescence. It can greatly affect the natural hormonal background of a growing girl's body. The drug is contraindicated in people who are sensitive to the active substance, levonorgestrel, those who have suffered, women with liver disease and thrombosis.

Postinor is used in emergency cases to prevent pregnancy. Tablets are drunk once. Contraceptives can be up to 95% effective if used correctly. The main thing is timely use, no later than 72 hours after unprotected intercourse. Abuse of the drug can lead to health problems.

No matter how sad it is to write about it, but postinor in Russia ranks second among contraceptive methods. On the first, as you know, is. And yet, many women, despite the large selection of contraceptives, use postinor to prevent unwanted pregnancy, forgetting or not knowing about the complications, and what danger the harmless 2 pills pose in the future.

Meet Postinor

Postinor is produced in a package in which there are only 2 tablets (only the number of tablets should suggest that this is not a drug for regular use). One tablet contains 750 mcg of levonorgestrel, which has an emergency contraceptive effect. Levonorgestrel has antiestrogenic and progestogenic properties.

Postinor refers to emergency or fire contraception, and should be used only in exceptional cases, and not constantly and regularly.

How does postinor work?

The contraceptive effect of the drug is in three points. Firstly, levonorgestrel prevents the release of the egg from the follicle, that is, it inhibits ovulation (this moment is especially relevant in the preovulatory and ovulatory phases). Secondly, levonorgestrel, as a progestogen, changes the structure of the uterine mucosa and causes "glandular regression" of the endometrium, which makes it impossible for a fertilized egg to penetrate into the uterine wall (violation of implantation). This mechanism is comparable to, that is, conception has already occurred, but the uterus expels the egg. And thirdly, levonorgestrel causes changes in the mucus in the cervical canal, making it viscous and thick. Such mucus plays the role of a barrier and makes it difficult for sperm to enter the uterine cavity.

From the described mechanisms of action of postinor, it becomes clear that the effectiveness of the drug is directly proportional to the time it is taken after unprotected sex. After using postinor 24 hours or less after sexual intercourse, it will protect against unwanted pregnancy in 95% of cases, when taking pills after 25-48 hours, the effectiveness is 85%, and if postinor was taken in the interval from 49 to 72 hours, its reliability decreases up to 58%.

Rules for accepting a postinor

If a woman vomits within three hours after taking a postinor tablet (regardless of the first or second one), an additional tablet should be taken. Menstrual-like bleeding (withdrawal bleeding) can occur a few days after taking the drug (on average after 3 to 7 days) and about a month later (at the time of the expected period).

Postinor is not a means for regular contraception, if a woman has an active sex life, she should consult a doctor and choose the best method of contraception. It is believed that you can not use the drug more than once a month, and preferably no more than 4 times a year. In fact, it is better not to resort to postinor at all, but to use it only in an exceptional situation.

When is postinor justified?

Life is an unpredictable thing and there are situations when it is necessary to prevent pregnancy:

• rape;
• the condom broke;
• unprotected intercourse for various reasons;
• expulsion of the intrauterine device or shift of the vaginal diaphragm;
• missed taking a pill from a series of combined oral contraceptives.

Consequences after using postinor

Since the drug contains an "elephant" dose of the hormone, its use can adversely affect a woman's health. Firstly, there is a high probability of uterine bleeding, which can only be stopped surgically (that is, by curettage of the uterus). Secondly, taking postinor, especially more than once in a lifetime, hits the ovaries, which leads to menstrual irregularities, hormonal imbalance and anovulation. All of these effects are a direct path to infertility. Thirdly, a large dose of levonorgestrel cannot but cause side effects:

• nausea and vomiting, diarrhea;
• headache, dizziness;
• mood swings (emotional lability, panic fears);
• delay of menstruation;
• allergic reactions;
• pain in the lower abdomen, fatigue;
• pain and engorgement of the mammary glands.

The mechanism of action of levonorgestrel (D-13b-ethyl-17b-ethynyl-17-hydroxy-4-gonen-3-one) at the indicated dose is mainly due to the inhibition of ovulation and the prevention of fertilization (in the event that sexual intercourse occurred before ovulation, when the probability of fertilization is higher), as well as changes in the endometrium when taking the drug, preventing the implantation of a fertilized egg. The drug is ineffective if implantation of a fertilized egg has already occurred. When using Postinor, unwanted pregnancy can be prevented in approximately 85% of cases. The longer the interval between sexual intercourse and taking Postinor, the lower the effectiveness of the drug (in the first 24 hours - 95%; from 24 to 48 hours - 85%; from 48 to 72 hours - 58%). There are no data on the effectiveness of the drug when taken 72 hours after sexual intercourse. At the recommended dose, levonorgestrel does not have a significant effect on blood clotting, lipid and carbohydrate metabolism.
After oral administration, levonorgestrel is rapidly and almost completely absorbed. After taking 1 tablet of Postinor, the maximum concentration of levonorgestrel in the blood serum (on average, 14.1 ng / ml) is reached after 1.6 hours. Then the decrease in the concentration of levonorgestrel occurs in two stages, the half-life ranges from 9 to 14.5 hours.
Levonorgestrel is excreted from the body in the form of metabolites with urine and feces in approximately equal amounts. The biotransformation of levonorgestrel is similar to that of steroids. The drug is hydroxylated in the liver, and its metabolites are excreted in the form of glucuronides. Known metabolites of levonorgestrel do not have pharmacological activity.
Levonorgestrel binds to plasma proteins, mainly albumin and sex hormone-binding globulin. Only 1.5% of the administered dose is in the blood serum in free form, and 65% have a specific relationship with sex hormone-binding globulin. Absolute bioavailability is almost 100%. About 0.1% of the drug dose is excreted in breast milk.

Emergency prevention of unwanted pregnancy if the drug is used within 72 hours after sexual intercourse and other contraceptives were not used or they turned out to be unreliable.

The use of the drug Postinor

To achieve a more reliable effect, the first tablet should be taken as soon as possible after intercourse (but not later than 72 hours), and the second - 12 hours (but not later than 16 hours) after taking the first. If vomiting occurs within 3 hours after taking any tablet, another 1 tablet should be taken.

Special instructions for the use of the drug Postinor

The drug can be used only in extreme cases. Postinor is not a contraceptive for regular use. Its reception does not always prevent pregnancy. If a woman does not remember when sexual intercourse took place, or if unprotected intercourse has already taken place in the same menstrual cycle 72 hours before taking the drug, fertilization is possible. In this case, the use of the drug is ineffective. If menstruation is delayed by more than 5 days or its onset is timely, but the course is different from usual, pregnancy must be excluded.
If, despite the use of the drug Postinor, fertilization still occurred, the possibility of an ectopic pregnancy should be considered.
The use of Postinor is not recommended for severe liver dysfunction. Severe bowel disease (eg, Crohn's disease) may cause impaired drug absorption .

Hello! I took Postinor 25 hours after the unprotected PA, the next pill - 12 hours later, according to the instructions. For the third day I have not observed any consequences, only yellowish discharge, similar to thrush. Can you tell me, please, is it possible that these are signs of pregnancy ??
Thank you!

If intermenstrual bleeding does not begin on the 5-7th day of taking the drug, it is necessary to consult a gynecologist and donate blood for hCG, to exclude pregnancy.

Karina asks:

Hello! I took Postinor after 36 hours, and after 5 days the action will begin? If there is no pregnancy, will there still be bleeding?

Postinor begins to act immediately after taking the tablet (after it is dissolved and absorbed in the intestine). Bleeding, which should appear 5-6 days after the use of this drug, indicates the highest contraceptive effect and the exact absence of pregnancy. If there is no bleeding at all or it occurs later, you will need to undergo an examination by a gynecologist to exclude pregnancy. You can read more about Postinor and its effects on the body in our section: Postinor.

hello! immediately after unprotected intercourse, I drank a glass of milk with iodine, after which, within 24 hours, I drank the first postinor tablet (the second one, as per the instructions), but after 5 days there were no changes, is there a chance that there is a pregnancy?

As a rule, bleeding after Postinor begins 6 days after taking the last pill. If it is absent, then it is necessary to exclude the possibility of pregnancy. To do this, I recommend that you do a blood test for hCG 7-10 days after intercourse. You can get more information on this issue in the section: Analysis for hCG

Maria asks:

I had intercourse for two days in a row, and both times they didn’t use protection, everything about me, 48 hours after the first time, I drank Postinor, but it turned out that I got pregnant anyway, could it be?

Unprotected intercourse, after 3 hours I immediately drank 2 Postinor tablets (I didn’t read the instructions, unfortunately), then I had sexual intercourse during the day. It's been 5 days with slight bleeding. Q: Is it a long acting drug?

The emergency contraceptive Postinor, according to the instructions, must be used according to the scheme - 2 tablets with an interval of 12 hours, and the contraceptive effect extends to sexual intercourse that took place before Postinor was taken. The presence of spotting indicates the absence of pregnancy, so you should not worry. We recommend that you do not panic and continue to use barrier methods of contraception, and if you have regular sex life, personally consult with your gynecologist to select a reliable contraceptive.

Elena asks:

The condom broke in the middle of the menstrual cycle. After 4 hours I drank the first tablet of Postinor, after 12 hours the second. There are no sensations, today is the 4th day after unprotected intercourse, there is no discharge. Did Postinor work?

As a rule, after taking the hormonal contraceptive Postinor, spotting is observed after 6 days, but in some cases it may be absent, which, nevertheless, does not give grounds to judge the absence of the effect of the use of this emergency contraceptive. Given that the drug was taken in a timely manner, there is no reason to panic.

Elena asks:

On the 8th, my partner and I had an unprotected PA. He did not cum inside me, after about 25 hours I took the first pill and after 12 hours I took the second. Can you please tell me how to help? How soon should menstruation start?

If during intercourse there was no ejaculation in the vagina, then there is no chance of pregnancy. In this situation, there was no need to use Postinor emergency contraception. After taking this medicine, spotting usually starts after 6 days, and the next menstruation may come late.
