Complications after postinoration. Postinor: consequences. Consequences of taking postinor Postinor what effect

Life is full surprises. And often something happens that you don’t expect at all. For example, unprotected sexual intercourse leads to unwanted pregnancy. For such cases, pharmacists have developed emergency contraceptives. These include Postinor tablets.

Emergency contraception with Postinor. Indications. Postinor is an emergency medicine. It is indicated in cases where other methods of protection have not worked or failed. It should be taken in the first three days after unprotected intercourse. Postinor shows maximum effectiveness on the first day, then its effect weakens. Each package of the medicine contains two tablets, they must be taken at intervals of 12 hours. The active component of the tablets is levonorgestrel. Postinor contains a very large dose of hormones, so it can only be taken as a last resort.

The principle of operation of postinor

Mechanism of action next: the active component of the tablets prevents the release of the egg from the ovary, or prevents possible fertilization. In the case when fertilization has occurred, Postinor prevents the fertilized egg from entering the walls of the uterus. However, if this has already happened and the embryo is implanted, Postinor is powerless. It can prevent pregnancy, but not terminate it. Therefore, taking Postinor is effective only for 72 hours. And the sooner you take it, the less difficult the contraception process is.

According to research experts, this remedy helps prevent pregnancy only in 85% of cases. This means that it is also not a completely effective method of protection.

Consequences after taking postinor

Like many others medications, Postinor has side effects, the consequences after administration can be expressed in various bleedings. This happens because taking this drug increases the level of progestogen in the blood - this is the hormone responsible for thickening the endometrium. Most often, bleeding appears after taking up to 3 Postinor tablets for a short time.

Postinor categorically forbidden use as a permanent means of contraception. When taken more often than once a month, the level of hormones contained in the medicine will sharply increase in the body. In addition, these pills will not protect you from sexually transmitted infections.

Sometimes after taking Postinora dizziness, pain in the lower abdomen, lethargy and fatigue occur. All these symptoms do not require treatment and disappear within a few days. If other reactions appear and do not go away, you should consult a gynecologist.

Menstruation and discharge after taking postinor

Mostly, menstruation after taking the pills, your period comes at the usual time, but sometimes your period may come a few days earlier or later than expected. It is possible that the bleeding will be more severe and prolonged. Minor spotting may occur for 3-4 days. If Postinor causes a miscarriage in the early stages, then your period will begin a few days after taking it. And, as a rule, abundant, accompanied by sharp pain in the lower abdomen.

If after Postinora menstruation is too light or, on the contrary, more intense than usual, contact your doctor. You should also contact a gynecologist if there was no bleeding at all after taking the pills. Perhaps this is simply a cycle disruption due to the large intake of hormones into the body. But in any case, visiting a doctor won't hurt.

Postinor analogues

If, by various reasons, You cannot take Postinor, pay attention to its analogues, they may well replace it:
- Levonorgestrel;
- Escapelle;
- Eskinor-F;
- Mirena;
- Microlute;
- Norplant.

Postinor, and its analogues Escapel, Microlut, Eskinor F, are a means of contraception only in emergency cases, that is, for life-threatening reasons, such as rape, rupture of a condom during sexual intercourse.

Why can't it be used on an ongoing basis? This drug in developed countries can only be purchased with a prescription, unlike in Russia, since Postinor has serious side effects.

However, some women use these drugs quite often, without consulting a gynecologist and not knowing about the consequences, complications, side effects of Postinor and its analogues. To understand what effect these drugs have on the body, you should know the mechanism of their action.

Mechanism of action of Postinor

Postinor causes a lot of side effects and its use is possible only in extreme cases. During puberty and for women planning to have children in the future, its use is not advisable, since this can lead to hormonal imbalance in a woman and cause infertility in the future.

Postinor and its analogues are intended only for emergency prevention of pregnancy. The active ingredient of the drug is levonorgestrel, of which there is 0.75 mg in one tablet, which is considered a lethal dose. In low-dose oral contraceptives, for example, this dose of levonorgestrel is contained in 20 tablets. The Postinor package contains 2 tablets, which are taken 12 hours apart for 72 hours after unprotected sexual intercourse. The mechanism of action of levonorgestrel is as follows:

• a drug blocks ovulation- prevents a mature egg from leaving the ovary
• when ovulation has already occurred, Postinor prevents implantation of the fertilized egg in the uterine cavity - in this case it essentially has an abortifacient effect
• leads to a change in cervical mucus, it becomes thicker, which interferes with the penetration of sperm into the uterine cavity.

When the implantation of a fertilized egg into the wall of the uterus has already occurred, the drug becomes ineffective, since all gestagens have the property of suppressing the motor activity of the uterine muscles.

Contraindications

The use of Postinor is contraindicated for use in the following cases:

• liver dysfunction, severe liver disease
• teenage girls under 16 years old
• During lactation, the drug passes into breast milk, so it is contraindicated during breastfeeding.
• with uterine bleeding of unknown origin
• for individual intolerance
• for herpetic infections and other infectious diseases of the genitourinary system
• in diseases associated with enzymatic deficiency - impaired absorption of glucose, galactose (lactase deficiency)
• for malignant neoplasms of any location
• with a genetic predisposition to thrombosis

Use with caution for ulcerative lesions of the gastrointestinal tract, diseases of the biliary tract.

Side effects of Postinor

Any medications have side effects, and Postinor is a powerful hormonal drug, which in some cases can become a trigger for the development of serious health problems in a woman. Therefore, in developed countries this drug is available only by prescription and is considered an unsafe method of contraception. Side effects of Postinor are as follows:

• Intestinal dysfunction - diarrhea
• Digestive disorders - vomiting, diarrhea
• Headache, dizziness
• Intermenstrual bleeding
• Breast tension
• Flu-like symptoms
• Weakness, lethargy

If you experience any side effects from taking Postinor or other unusual signs of illness, you should consult a doctor.

Side effects from the reproductive system, impact on the woman’s reproductive function in the future

Considering that 1 tablet contains a huge amount of active substance, a real hormonal imbalance occurs in a woman’s body after taking Postinor. The instructions for the drug say that it is not recommended to use it more than 4 times a year. But some women often neglect these recommendations and take it uncontrollably, sometimes even several times per menstrual cycle, which is very dangerous and prohibited.

Since Postinor should be taken when there is a high probability of pregnancy (ovulation period) - at this time the mucous membrane of the uterus has not yet matured, which leads to dysfunction of the ovaries, and then they produce either less or more hormones. And even with a one-time use of the drug, a certain time is required (in each case individually) to restore ovarian function.

Therefore, if a woman with existing menstrual irregularities:

• irregular menstruation
• teenagers under 16 years old

If you take the drug even once, such disruptions can be permanent and cause infertility in the future.

The influence of this hormonal drug, especially on an ongoing basis, leads to the fact that the function of the ovaries begins to fade, become depleted, and the production of hormones gradually becomes less and less. This causes irregularities in the menstrual cycle and can affect a woman's reproductive ability. In some cases, taking the drug leads to amenorrhea (lack of menstruation) and, as a result, persistent infertility. Even a timely visit to a gynecologist in such cases cannot guarantee the successful restoration of the normal menstrual cycle and the likelihood of pregnancy.

If a woman has periodic uterine bleeding, taking Postinor and its analogues can intensify it and lead to the need for emergency medical care, so in such cases taking the drug is unacceptable. Also, one of the side effects of Postinor is engorgement and soreness of the mammary glands, and the appearance of discharge from the nipples.

Other side effects of Postinor

In addition to disorders associated with hormonal shock, the effects of Postinor and Escapel, if taken incorrectly, can have other consequences, such as, for example, the formation of blood clots in blood vessels. This side effect can mainly occur in women with bleeding disorders, but even a seemingly healthy woman has this risk (see video - documentary).

After repeated use of maximum doses of hormones, blood clotting ability increases and the risk of blood clots in blood vessels increases. When the lumens of blood vessels are partially blocked, there is a reduction in blood flow to organs and tissues and, as the most extreme pathology, blockage of blood vessels (the occurrence of pulmonary thromboembolism). When blood vessels in the heart and brain become blocked, a stroke or instant death may occur.

If a woman does not have any problems with the menstrual cycle, side effects of Postinor occur quite rarely. But other ailments may appear - pain in the lower abdomen, nausea, diarrhea, headaches, swelling. Due to frequent use of Postinor, disturbances in fat and carbohydrate metabolism may occur, causing a decrease or increase in body weight, and suppression can lead to changes in male-type hair growth or changes in the contours of the figure.

Every woman who cares about her health should watch this video before deciding to take any oral contraceptives (even low-dose ones). This is especially true for young girls who want to have children in the future.

As sad as it is to write about this, Postinor in Russia ranks second among contraceptive methods. The first one, 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 harmless 2 tablets pose in the future.

Meet Postinor

Postinor is available in a package containing 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 consists of three points. Firstly, levonorgestrel prevents the release of the egg from the follicle, that is, it inhibits ovulation (this is especially important in the preovulatory and ovulatory phases). Secondly, levonorgestrel, as a gestagen, changes the structure of the uterine mucosa and causes “glandular regression” of the endometrium, which makes it impossible for a fertilized egg to penetrate the uterine wall (impaired 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. This mucus acts as a barrier and makes it difficult for sperm to penetrate into 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 tablets after 25–48 hours, the effectiveness is 85%, and if postinor was taken between 49 and 72 hours, its reliability decreases up to 58%.

Rules for taking postinor

Postinor can be taken on any day of the menstrual cycle. If a woman has an irregular menstrual cycle, the absence of pregnancy should be confirmed. The first tablet from the blister should be taken no later than 72 hours after coitus. The second dose should be taken exactly 12 hours later (the interval can be increased by 4 hours, that is, no more than 16 hours later).

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

Postinor is not a means for regular contraception; if a woman is sexually active, she should consult a doctor and choose the optimal method of birth control. It is believed that you should 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 use justified?

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

• rape;
• the condom broke;
• unprotected sexual intercourse for various reasons;
• expulsion of the intrauterine device or shift of the vaginal diaphragm;
• a missed dose 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, curettage of the uterus). Secondly, taking postinor, especially more than once in a lifetime, causes a blow to 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 changes (emotional lability, panic fears);
• delay of menstruation;
• allergic reactions;
• pain in the lower abdomen, fatigue;
• pain and engorgement of the mammary glands.

Elena asks:

Hello! My name is Lena, I'm 22 years old. We had sexual intercourse on July 25 and the condom broke. About an hour later I took a postinor tablet, the next one 17 hours later. Menstruation is constant, cycle is 28 days. Your period should start on July 27th. Please tell me how much this drug will help me, I was a couple of hours late with the second pill. And is pregnancy possible during these periods, do these seem to be safe days. Thanks for the help!!!

If sperm enters the female genital tract, pregnancy is possible. Prem of the drug Postinor significantly reduces the likelihood of pregnancy. Taking the first pill as early as possible is important in emergency contraception.

Katya asks:

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

If on the 5th-7th day of taking the drug, intermenstrual bleeding does not begin, you must consult a gynecologist and donate blood for hCG to rule out pregnancy.

Karina asks:

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

Postinor begins to act immediately after using the tablet (after its dissolution and absorption in the intestines). Bleeding, which should appear 5-6 days after using this drug, indicates the highest possible 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 rule out pregnancy. You can read more about the drug Postinor and its effect on the body in our section: Postinor.

Karina asks:

thanks for the answer! I have another problem ((in general, I drank as expected, after 5 hours my period started, my stomach hurt for 3 days, yesterday the tingling sensation in the lower abdomen began, in the evening it intensified, it hurts to press on the lower abdomen, today it’s the same, only it hurts less .could this be from postinor?

The listed symptoms may be associated with taking the hormonal contraceptive Postinor, so there is no need to worry. As a rule, these symptoms go away on their own; no specific measures are required. More information about this can be found in the section: Hormonal contraceptives

Anya asks:

Hello! Immediately after unprotected intercourse, I drank a glass of milk with iodine, after which within 24 hours I took the first postinor tablet (the second as per instructions), but after 5 days no changes occurred, is there a possibility that I am pregnant?

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 sexual intercourse. More information on this issue can be found in the section: Analysis for hCG

Maria asks:

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

Unfortunately, this situation is possible, since the drug Postinor is not 100% effective. In addition, the timing of taking Postinor is also important - the longer the interval from sexual intercourse to taking Postinor, the less effective it is. You can get more information on this issue in the thematic section of our website: Postinor

Rita asks:

the condom broke, it broke, I drank postinor after 8 hours, then follow the instructions. I have a question: my period should come in 1-2 days, how can I tell if my period comes, did the postinor work?

If you begin to have menstrual bleeding, pregnancy can be completely ruled out and this will mean that the drug has worked. Read more about the action of the drug Postinor in a series of articles by clicking on the link: Postinor.

My period began (as it should be according to the cycle, it coincided) 6 days after the act and taking the postinor. after 2 weeks, menstruation began again, or rather spotting, often black. 4 days later I got my heavy period. Can you tell me if this could be a consequence of taking Postinor and whether it will go back to normal in the next month or if I need to see a doctor urgently?

These bleedings are associated with taking the hormonal contraceptive Postinor. In such cases, there is no need to do anything; the menstrual cycle will resume on its own.

Marina asks:

Hello! I am 40 years old. Yesterday at 19.00 I had unprotected sexual intercourse, the very middle of the cycle, a dangerous week. This morning at 10.00 I took the first Postinor tablet, 15 hours have passed since PA. My lower abdomen hurt, my heart rate increased, in general, all the signs and effects of the drug. I'm waiting for the bleeding to start. My question is: Can I start taking Tri-Regol on the first day of bleeding after taking Postinor?

In this situation, you should take the second Postinor tablet after 12 hours, after which, as a rule, menstrual-like bleeding begins after 6 days. It is not the beginning of menstruation, so there is no need to take Tri-Regol - wait until your next menstruation and from the first day of the cycle you can use cyclic hormonal contraceptives if they are prescribed to you by your gynecologist.

Valentina asks:

I had my period on June 18, I had an unprotected PA on June 2, but my partner didn’t cum in me, I believe him.
About 10 hours later I drank Postinor, and 12 hours later I took another one, just in case.
Can pregnancy be ruled out already?
Or what should I expect?

In this situation, there was no need to use emergency contraception if there was no ejaculation into the vagina. Taking Postinor excludes pregnancy, so there is no reason to worry. Next, I recommend that you use barrier methods of contraception.

Elena asks:

Unprotected intercourse, after 3 hours I took 2 Postinor tablets at once (I didn’t read the instructions, unfortunately), then I had sexual intercourse within 24 hours. 5 days have passed - slightly bloody discharge. Question: 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 occurred before taking Postinor. The presence of bloody discharge indicates the absence of pregnancy, so there is no need to worry. We recommend that you do not panic and continue to use barrier methods of contraception, and if you have regular sexual activity, 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 took the first postinor tablet, and 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, bleeding is observed after 6 days, but in some cases it may be absent, which, however, does not give grounds to judge the lack of effect from the use of this emergency contraceptive. Considering that the drug was taken in a timely manner, there is no reason to panic.

Elena asks:

My partner and I had an unprotected PA on the 8th. He didn’t cum inside me, after about 25 hours I took the first pill and after 12 hours I took the second. Tell me please, should it help? How soon should my period start?

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

The mechanism of action of levonorgestrel (D-13в-ethyl-17в-ethynyl-17-hydroxy-4-gonen-3-one) at the indicated dose is mainly due to inhibition of ovulation and prevention of fertilization (in the event that sexual intercourse occurred before ovulation, when the likelihood of fertilization is higher), as well as changes in the endometrium when taking the drug, which prevent 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 is 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 achieved 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 in urine and feces in approximately equal quantities. 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 found in the blood serum in free form, and 65% has a specific association with sex hormone-binding globulin. Absolute bioavailability is almost 100%. About 0.1% of the drug dose is excreted in breast milk.

Indications for use of the drug Postinor

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.

Use of the drug Postinor

2 tablets inside. To achieve a more reliable effect, the first tablet should be taken as soon as possible after sexual intercourse (but no later than 72 hours), and the second - 12 hours (but no later than 16 hours) after taking the first. If vomiting is observed within 3 hours after taking any tablet, you should take 1 more tablet.
Postinor can be taken on any day of the menstrual cycle, but only if the previous menstruation was timely. After using the drug, barrier contraception must be used until the next menstruation. After using Postinor, taking permanent oral hormonal contraceptives is not contraindicated.

Contraindications to the use of the drug Postinor

Hypersensitivity to the components of the drug, age under 16 years (insufficient experience in using the drug).

Side effects of the drug Postinor

Nausea, pain in the lower abdomen, headache, fatigue, dizziness, tension in the mammary glands, vomiting, diarrhea, spotting menstrual-like bleeding. There may be irregularities in the menstrual cycle, but for most women, the next menstruation occurs on the expected date. If menstruation is delayed by more than 5 days, pregnancy must be excluded.

Special instructions for the use of the drug Postinor

The drug can only be used in extreme cases. Postinor is not a contraceptive for regular use. Taking it does not always prevent pregnancy. If a woman does not remember when sexual intercourse took place, or if unprotected sexual 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 normal, it is necessary to exclude pregnancy.
If, despite the use of the drug Postinor, fertilization still occurs, the possibility of ectopic pregnancy should be considered.
The use of Postinor is not recommended for severe liver dysfunction. Severe intestinal diseases (for example, Crohn's disease) may cause impaired absorption of the drug .
After using the drug, menstruation occurs at the expected time and occurs as usual. In some cases, menstruation may begin several days earlier or later than expected. After using Postinor, it is recommended to examine a doctor to decide whether to use the method for regular contraception.
If Postinor was taken due to a missed dose of a regular hormonal contraceptive, and menstruation did not occur during the next 7-day break in taking the contraceptive drug, pregnancy should be excluded.
Repeated use of Postinor during one menstrual cycle is not recommended due to possible disruption of this cycle.
Postinor should not be taken during pregnancy; the drug does not terminate an existing pregnancy. In the event of pregnancy with the use of progestogens, a teratogenic effect has not been identified.
Levonorgestrel practically does not pass into breast milk. The potential impact of levonorgestrel on infant development can be reduced if both tablets are taken immediately after breastfeeding and if breastfeeding is avoided after taking the drug.

Interactions of the drug Postinor

When used simultaneously with liver enzyme inducers, the metabolism of levonorgestrel is accelerated. The effectiveness of levonorgestrel can be reduced by barbiturates (including primidone), phenytoin, carbamazepine, St. John's wort (Hypericum perforatum), rifampicin, ritonavir, rifabutin, griseofulvin.
Drugs containing levonorgestrel may increase the toxicity of cyclosporine due to inhibition of its metabolism.

Overdose of the drug Postinor

Severe side effects after taking the drug in a high dose have not been described. Possible nausea and bleeding. There is no specific antidote, treatment is symptomatic.

Storage conditions for the drug Postinor

At a temperature of 15-25 °C.
