Postcoital contraceptive. Gestagen

Active substance

Levonorgestrel

Release form, composition and packaging

Tablets white or off-white, disc-shaped, beveled, circular engraved "INOR." on one side.

Excipients: colloidal silicon dioxide, potato starch, magnesium stearate, talc, corn starch, lactose monohydrate.

2 pcs. - blisters (1) - cardboard packs.

pharmachologic effect

Synthetic gestagen with a contraceptive effect, pronounced gestagenic and antiestrogenic properties. At the recommended dosage regimen, levonorgestrel suppresses ovulation and fertilization if sexual intercourse occurs in the pre-ovulation phase, when the possibility of fertilization is greatest. It can also cause changes in the endometrium that prevent implantation. The drug is not effective if implantation has already taken place.

Efficiency: with the help of Postinor tablets, pregnancy can be prevented in about 85% of cases. The more time elapsed between intercourse and taking the drug, the lower its effectiveness (95% during the first 24 hours, 85% - from 24 to 48 hours and 58% - from 48 to 72 hours). Thus, it is recommended to start taking Postinor tablets as soon as possible (but no later than 72 hours) after sexual intercourse, if no protective measures have been applied. At the recommended dose, levonorgestrel has no significant effect on blood clotting factors, fat and carbohydrate metabolism.

Pharmacokinetics

Absorption and distribution

When taken orally, levonorgestrel is rapidly and almost completely absorbed. Absolute bioavailability is almost 100% of the dose taken. After taking 750 μg of levonorgestrel, the C max in serum, equal to 14.1 ng / ml, is reached after 1.6 hours. After reaching C max, the content of levonorgestrel decreases. T 1/2 is about 26 hours.

Metabolism and excretion

Levonorgestrel is excreted in approximately equally by the kidneys and through the intestines exclusively in the form of metabolites. The biotransformation of levonorgestrel corresponds to the metabolism of steroids. Levonorgestrel is hydroxylated in the liver, metabolites are excreted in the form of conjugated glucuronides. Pharmacologically active metabolites of levonorgestrel are unknown. Levonorgestrel binds to blood serum and to sex hormone binding globulin (SHBG). Only 1.5% of the total dose is in free form, and 65% is associated with SHBG.

Indications

• emergency (postcoital) contraception (after unprotected sex or the unreliability of the contraceptive method used).

Contraindications

• hypersensitivity to the components of the drug;
• heavy;
• adolescence up to 16 years;
• pregnancy;
• rare hereditary diseases such as lactose intolerance, lactase deficiency or glucose-galactose malabsorption.

Carefully: diseases of the liver and biliary tract, jaundice (including history), lactation.

Dosage

The drug is taken orally. You must take 2 tablets in the first 72 hours after unprotected intercourse. The second tablet should be taken 12 hours later (but no later than 16 hours) after taking the first tablet.

To achieve a more reliable effect, both tablets should be taken as soon as possible after unprotected intercourse (no later than 72 hours).

If vomiting occurs within 3 hours after the 1st or 2nd dose of the Postinor tablet, then another Postinor tablet should be taken.

Postinor can be applied at any time menstrual cycle... In the case of an irregular menstrual cycle, pregnancy must be excluded first.

After taking emergency contraception before your next menstrual period, you should use topical barrier methods (eg, condom, cervical cap). The use of the drug with repeated unprotected intercourse during one menstrual cycle is not recommended due to an increase in the frequency of acyclic bleeding.

Side effects

Allergic reactions: possibly hives, rash, itching, swelling of the face.

Transitory side effects occurring with different frequencies and not requiring drug therapy: very often (≥1 / 10), often (≥1 / 100,<1/10)

On the part of the reproductive system: very often - pain in the lower abdomen, acyclic spotting (bleeding); often - soreness of the mammary glands, delayed menstruation (no more than 5-7 days, if menstruation is delayed for a longer period, pregnancy must be excluded).

From the digestive system: very often - nausea; often - vomiting, diarrhea.

From the nervous system: often - dizziness, headache.

Others: very often - fatigue.

Overdose

Symptoms: increased severity of side effects.

Treatment: there is no specific antidote. Symptomatic therapy is performed.

Drug interactions

With the simultaneous administration of drugs-inducers of liver enzymes, the metabolism of levonorgestrel is accelerated.

The following drugs may decrease the effectiveness of levonorgestrel: amprecavil, lansoprazole, oxcarbazepine, tacrolimus, topiramate, tretinoin, barbiturates, including primidone, phenytoin, and carbamazepine; preparations containing St. John's wort (Hypericum perforatum), as well as rifampicin, ritonavir, tetracycline, rifabutin, griseofulvin.

Levonorgestrel reduces the effectiveness of hypoglycemic and anticoagulant (coumarin derivatives, phenindione) drugs. Increases plasma concentrations of GCS. Women taking these drugs should see a doctor.

Medicines containing levonorgestrel may increase the risk of toxicity by suppressing its metabolism.

special instructions

Postinor should be used exclusively for emergency contraception. Repeated use of the drug Postinor during one menstrual cycle is not recommended.

The effectiveness of Postinor tablets after unprotected intercourse, in which contraception was not used, decreases over time:

The drug does not replace the use of permanent methods of contraception. In most cases, Postinor does not affect the nature of the menstrual cycle. However, acyclic bleeding and delayed menstruation by several days are possible. If menstruation is delayed by more than 5-7 days and its nature changes (scant or abundant discharge), pregnancy must be excluded. The appearance of pain in the lower abdomen, fainting conditions may indicate an ectopic (ectopic) pregnancy.

In exceptional cases (including rape), adolescents under 16 years of age need to consult a gynecologist to confirm pregnancy.

After emergency contraception, it is recommended to consult a gynecologist to select the most appropriate method of permanent contraception.

Emergency contraception does not protect against sexually transmitted diseases.

In case of violations of the gastrointestinal tract (for example, with Crohn's disease), the effectiveness of the drug may decrease.

Influence on the ability to drive vehicles and mechanisms

The influence of Postinor on the ability to drive vehicles and mechanisms has not been studied.

Pregnancy and lactation

Postinor is contraindicated for use during pregnancy. If pregnancy occurred when using an emergency method of contraception, then on the basis of the available data, no adverse effect of the drug on the fetus has been identified.

Conditions of dispensing from pharmacies

The drug is available with a prescription.

Storage conditions and periods

The drug should be stored out of the reach of children at a temperature of 15 ° to 25 ° C. The shelf life is 5 years.

The choice of the majority of Russian women when it is necessary to use emergency contraception as a result of unsafe sexual intercourse most often falls on the drug Postinor, the active fraction of which is levonorgestrel.

Medicines of this pharmacological group contribute to the induction of medical abortion at the initial stage of gestation by creating obstacles to embryo implantation. We will talk about how often you can drink Postinor in this article.

• Conclusion

How often can you take Postinor?

How many times can you drink Postinor? It is hypothetically possible to use this type of contraception 12 times a year.

However, do not forget that the drug is intended only for extreme cases, and one tablet contains a loading dose of the hormone. The risk of disruption to the regularity of the cycle increases, and dysfunction of the female reproductive glands may develop.

The use of this medication as a conventional contraceptive is unacceptable and fraught with consequences. Two tablets must be taken, each containing 0.75 mg of levonorgestrel.

Such a significant dose of synthetic progestogen, used on an ongoing basis, cannot but affect the functioning of the woman's reproductive system. Whereas modern combined oral contraceptives are presented in sparing micro doses. That is why you cannot drink Postinor twice a month.

What will happen if you take Postinor often? With repeated administration of Postinor, its side effects are enhanced.

The greatest danger is posed by acyclic spotting, menstrual irregularities and delays in the onset of menstrual bleeding are characteristic. There is a risk of uterine bleeding, in this case it is necessary to seek qualified gynecological help.

Thus, to the question: “How many times can you take Postinor?”, The answer is not to abuse it. Next, let's talk about whether it is possible to drink Postinor after an abortion?

Watch a useful video about Pastinor:

Postinor after medical abortion

It is highly undesirable to use Postinor after an abortion, even after a medical abortion.

Medicinal abortions are performed using synthetic antigestagens (eg, Mifepristone).

When used together, they exacerbate each other's negative actions. We are talking about bloody discharge from the female genital tract, menstrual irregularities. The most formidable complication from exposure to such combinations of medications is profuse uterine bleeding, which requires urgent hospitalization.

After a drug termination of pregnancy, at least two regular restored menstrual cycles should pass, and only then can Postinor's help be used with unprotected sexual intercourse.

What happens if you often drink the drug?

Let's go back to how often you can use Postinor? The consequences of taking Postinor can pose a threat to a woman's health. The side effects of this medicine are various types of bleeding. This phenomenon is associated with the high level of the hormone levonorgestrel in the pill, which affects the endometrium of the uterus, thickening it.

Frequent use of Postinor is complicated by bleeding, precisely with repeated administration for a short period of time, more than once in one cycle.

On the other hand, Postinor is capable of causing a diametrically opposite effect in the form of aminorrhea, that is, the absence of menstruation.

In this case, it is necessary to consult a gynecologist in order to exclude gestation. In addition to bleeding, drug abuse can lead to the development of less dangerous, but not more pleasant complications, such as: vomiting, nausea, apathy, headache. If vomiting occurs three hours after the first or second pill, then you need to take another Postinor pill.

Conclusion

Postinor is applicable only for the purpose of implementing "fire" contraception, and is recommended for women with a regular cycle without interruptions and delays.

Gynecologists do not welcome the abuse of this medication, as it has a detrimental effect on the state of the body.

Can I drink Postinor 2 times a month? No. How many times a month can you drink postinor? No more than once per cycle.

Drinking Postinor tablets should be done with caution, only in cases of urgent need after unprotected intercourse, only once during one menstrual cycle.

The tool cannot become an analogue of a permanent method of contraception, as it causes a number of side effects that can harm the state of health.

Medical termination of pregnancy and Postinor's reception should not be combined due to the increased risk of dangerous complications.

We hope that our article will be useful to you and you will firmly remember how often Postinor can be used, how many times a year can Postinor be drunk and can Postinor be drunk after medical termination of pregnancy?

Postinor tablets: instructions for use, analogues

Postinor is a synthetic contraceptive drug designed to prevent unwanted pregnancies. This medicine belongs to the group of hormonal emergency contraception and is used after unprotected intercourse (within 72 hours). Postinor tablets are able to prevent pregnancy in 85% of cases.

The drug is not intended for use on an ongoing basis, its use requires prior consultation with a gynecologist, since a contraceptive can cause serious adverse reactions. Let's take a closer look at how Postinor works, what are the consequences of taking it, what effect it has on a woman's body and how to use it correctly.

Postinor tablets - the effect of the drug

Postinor is a postcoital contraceptive intended for oral administration. The basis of the drug is the artificial hormone levonorgestrel, which has a pronounced antiestrogenic and progestogenic effect. The mechanism of this action consists of three components:

1. The active substance of the drug delays and blocks ovulation, preventing the mature egg from leaving the ovary into the fallopian tube, thereby preventing its fertilization.
2. Taking Postinor helps to change the composition of cervical mucus, it becomes thicker, preventing sperm from entering the uterus and fertilizing an egg.
3. If ovulation does occur, the drug prevents the penetration of the fertilized egg into the uterine cavity, that is, in fact, it has an abortive effect.

In the event that the implantation of a fertilized egg has already taken place, the drug is ineffective.

Contraceptives Postinor are recommended to be taken as soon as possible after intercourse, since the more time elapses between contact and taking a contraceptive, the lower the effectiveness of the drug will be. Answering the question whether it is possible to get pregnant after Postinor, doctors cite the following facts: if the contraceptive is used on the first day after intercourse, then unwanted pregnancy can be avoided in 95% of cases.

If the drug is taken within 48 hours - its effectiveness is 85%, if used within 72 hours - successful prevention of pregnancy is noted in 58% of cases.

When taken orally, the drug is completely and quickly absorbed, the maximum concentration of the active substance in the plasma is reached after 1.6 hours. Then the concentration of levonorgestrel begins to gradually decrease, the half-life of the drug is about 26 hours.

The bioavailability of the drug is absolute, that is, almost 100% of the dose taken enters the bloodstream. The active substance is biotransformed in the liver, excreted from the body in the form of metabolites equally through the kidneys and intestines.

Release form and analogues

Postinor is available in the form of tablets for oral administration. Disc-shaped white tablets are chamfered and circularly engraved with "INOR" on one side. 1 tablet of Postinor contains 0.75 mg of levonorgestrel + excipients.

Such a high dose of an artificial hormone determines the effectiveness of Postinor. For comparison, in low-dose oral contraceptives, this amount of levonorgestrel is contained in 20 tablets. The drug is stored in a dry place, out of the reach of children, at temperatures up to 25 ° C. Shelf life is 5 years.

The package with the drug contains 2 Postinor tablets, they are taken at intervals of 12 hours during the first three days after unprotected sexual intercourse.

Postinor has several analogues in terms of the active substance, which are no less effective in preventing unwanted pregnancy. The most popular ones are:

• Escapel
• Eskinor- F
• Norplant
• Ginepristone
• Microlute

Which means to give preference should be decided in conjunction with the gynecologist. All of these drugs are effective, but they have quite serious side effects. Only a specialist can choose the best option for a woman, taking into account possible contraindications and the woman's general health. To avoid possible complications, it is not recommended to use Postinor or its analogs on your own.

How much does Postinor cost?

In pharmacies, the average price for a pack of Postinor containing 2 tablets is 320 rubles. The cost of the drug is quite acceptable, given the fact that the contraceptive is not intended for systematic use, but is used only in urgent cases.

Indications

Oral contraceptives are used only in extreme cases, it cannot be used systematically, this can lead to the development of unwanted complications. Women should remember that the drug is not always able to prevent pregnancy, since its effect is most effective during the first days after contact.

Instructions for use

Instructions for use Postinor prescribes to take two tablets within the first 72 hours after unprotected contact. First, they take one pill, then, after 12 hours, they drink the second. In order to achieve the desired effect, the drug must be taken as soon as possible after intercourse.

If vomiting occurs within three hours after taking the first or second pill, you need to drink another contraceptive pill. The drug can be taken on any day of menstruation, it is desirable that the woman has a regular menstrual cycle. Repeated use of the medication during one cycle is not recommended, since spotting is noted after Postinor, and, moreover, with frequent use of the drug, uterine bleeding may open.

After using emergency contraception and until the next menstrual period, the woman should be protected with local contraceptives (cervical cap, condom).

A woman needs to remember that contraceptive Postinor can often not be taken, uncontrolled use can further cause serious complications and even lead to an ectopic pregnancy. The drug contains a "lethal" dose of the hormone levonorgestrel, which is capable of provoking profuse uterine bleeding.

A frequent occurrence when taking Postinor is a delay in menstruation and a failure of the menstrual cycle. Therefore, to the question of women: “How many periods after Postinor? »It can be difficult for specialists to give an exact answer. In some cases, the delay may indicate contraceptive abuse or be the result of an unplanned pregnancy.

Late use of Postinor does not guarantee the prevention of fertilization, therefore, with any delay in menstruation, you should consult with a specialist to exclude pregnancy.

Young girls often face the problem of an irregular menstrual cycle and ask gynecologists if Postinor can be taken with a delay in menstruation. The hormonal component of the drug can help in such a situation, and the girls note that after Postinor, menstruation went and the cycle stabilized. But you can use a contraceptive for these purposes only after consulting a specialist, in no case should you take the drug systematically.

Contraindications

Postinor is contraindicated for use in the following conditions:

During lactation, you should refrain from taking postinor contraceptives, since the active substance can penetrate into breast milk. If an unforeseen situation arises and the urgent need to use Postinor, doctors recommend doing the following.

Before taking the drug, the young mother is offered to feed the baby, then express breast milk and take 2 contraceptive pills at once. It is not recommended to breastfeed the baby for the next 24 hours; expressed milk or baby food can be used for feeding. After a day, you can return to breastfeeding.

• Headache, dizziness
• Vomiting, nausea, diarrhea
• Soreness and engorgement of the mammary glands
• Delayed menstruation (up to 7 days)

If the arrival of menstruation is delayed for a longer period, it is necessary to consult a gynecologist in order to exclude pregnancy.

In addition to these side effects, patients often note that in response to taking the drug, lethargy, a feeling of fatigue occur, and pain in the lower abdomen may appear. The most threatening consequence of taking Postinor may be the development of bleeding. This is due to the action of an active hormone, which increases the level of progestogen, which is responsible for the state of the endometrium of the uterus.

Bleeding can also develop as a result of improper administration of Postinor, when a high dose of the drug is taken for a short time. Overdose can provoke uterine bleeding. In such cases, you will need urgent medical attention.

Frequent use of the drug is highly undesirable, experts warn that the systematic use of Postinor increases the risk of developing ovarian dysfunction and, ultimately, can lead to infertility. It is advisable to use an emergency contraceptive no more than once every three months.

When used repeatedly during one menstrual cycle, the medication can cause various disorders (delayed menstruation, uterine bleeding). The appearance of fainting or severe pain in the lower abdomen may indicate the onset of an ectopic pregnancy. This condition requires hospitalization and surgery.

It is forbidden to use Postinor as a means of continuous contraception. The drug contains an artificial hormone in high doses, so regular use can lead to the development of severe adverse reactions and complications, up to and including infertility.

Postinor does not replace regular contraception, it is used only in cases where other methods of preventing unwanted pregnancy fail (violation of the integrity of the condom, a pass in taking a regular oral contraceptive).

In the case of the development of uterine bleeding caused by taking the drug, it is imperative to be examined by a gynecologist. The contraceptive is not able to terminate a developing pregnancy. If conception occurs while taking the drug, then you should not panic, since there is no risk of negative impact on the developing fetus from Postinor. It should be remembered that the use of emergency contraception is not able to protect against sexually transmitted diseases.

Postinor does not affect the ability to drive vehicles or perform work that requires concentration of attention and high reaction speed. Reviews of women about the drug are mostly positive, but some of them indicate that the use of an "emergency" contraceptive can provoke hormonal failure and negatively affect reproductive function.

Reviews on the use of contraceptive Postinor

Review number 1

She took Postinor once in her life, and this experience was negative. It all happened in my youth, at this time I was dating a guy. We were of course protected, but there were also unprotected contacts. And after one such incident, I counted the days and realized that I had a dangerous period, and I could easily get pregnant. This was not part of my plans.

At that time, I was studying at the university, preparing to defend my diploma, hatching plans for further employment and career growth. My friend often used Postinor, I also decided to take a contraceptive. I bought it at the pharmacy without a prescription, it was not cheap at all, there were only 2 tablets in the package. In the morning I drank Postinor according to the instructions and went to the university. Soon I felt bad, there was a strong weakness, nausea, vomiting opened.

I was turned inside out, only bile was coming out of my stomach, and it was dark in my eyes. I barely made it home and came to my senses for two days. In fact, I never took the second pill. It's good that everything worked out, and there was no pregnancy. But I no longer risked taking this drug, I use other contraceptives.

Irina, Chelyabinsk

Review number 2

Postinor had to be taken several times in emergency situations. Being married, they were protected by a barrier method, that is, using a condom. Well, several times the product failed (torn), we had to insure ourselves and take Postinor. I had no side reactions to this drug, otherwise I read horror films from other women on the Internet, that vomiting opened and bleeding began.

Everything went smoothly for me, although after taking the contraceptive pills, the cycle shifted for several days, and my periods came a little later. And I also noticed that they became more prolonged and painful. The rest of the drug always helped out, there was no unwanted pregnancy.

Lenara, Moscow

Review number 3

I already had the experience of taking Postinor in the past. In my youth, I drank it several times in emergency situations. Then everything was fine, there were no side effects. Now I am 38 years old, two children. Recently I had to remove the coil, protected with a condom, but a situation happened that the contraceptive was not available at the right time.

I decided to play it safe and the next day I bought Postinor, took it according to the instructions. A few days later, I did a pregnancy test, it turned out to be positive. I went to see a gynecologist, did an ultrasound scan - the result is negative. I chalked it up to a low-quality test. But she began to notice that something was wrong with me, noted the engorgement and soreness of the mammary glands, constantly felt pulling pains in the abdomen.

After a while, I felt bad, there were sharp pains, began to lose consciousness. We were taken to the hospital and diagnosed with an ectopic pregnancy. There was an operation, the fallopian tube was removed, then postoperative problems were haunted for a long time. I think that Postinor became the reason for this state. Now I will avoid using such drugs.

Postinor: clear instructions for use | My Gynecologist

Postinor is an emergency contraception that helps prevent unwanted pregnancy if intercourse has already taken place.

ATTENTION: The drug has contraindications. Do not start using this drug without first consulting your doctor.

Composition of tablets and packaging

One Postinor tablet contains the hormone levonorgestrel at a dose of 0.75 mg. The package contains two tablets.

Postinor's analogs

The emergency contraceptive drug Escapel contains the same hormone as Postinor. The main difference between these drugs is that in Postinor the dose of the hormone is divided into two doses, and in Escapel the entire dose is included in one dose. Both drugs are equally effective.

How does Postinor work?

If intercourse occurred in the first half of the menstrual cycle, then Postinor prevents ovulation (the release of an egg from the ovary), which makes conception impossible. If unprotected sex happened after ovulation has occurred, then Postinor changes the structure of the uterine mucosa in such a way that the fertilized egg cannot gain a foothold in the uterus.

It is important to understand that Postinor pills are not an abortion tool. This medication may prevent pregnancy from occurring, but is not effective if the pregnancy has already occurred.

How effective is Postinor?

Postinor's effectiveness depends on how soon he was adopted after intercourse. In the first 24 hours after unprotected sex, Postinor will work in 95% of cases, if after intercourse from 24 to 48 hours have passed, then its effectiveness will be 85%, and if a woman drank Postinor 48-72 hours after sex, then it will avoid pregnancy in 58% of cases.

Postinor is not effective if more than 72 hours have passed after intercourse (more than 3 days). Also Postinor is not effective if pregnancy has already occurred.

Should I drink Postinor?

Before taking Postinor, you should know in which cases its reception is really justified. You can take Postinor if in the previous 72 hours:

you have had unprotected intercourse (with or without vaginal ejaculation);

a condom broke or slipped during intercourse;

intercourse took place more than 3 days ago;

you are already pregnant (the pregnancy test is positive);

intercourse has not yet taken place, but is planned.

Contraindications to taking Postinor

with severe violations of the liver and diseases of the gallbladder;

during pregnancy;

Postinor application rules

Take the first Postinor tablet as soon as possible after intercourse. The second tablet should be taken 12-16 hours after the first. If the second pill was taken later than 16 hours after the first, then the effectiveness of the drug may be reduced.

Delay after taking Postinor

After taking Postinor, there may be a delay in menstruation by 5-7 days. This happens especially often if the drug was taken in the first half of the menstrual cycle.

In case of a delay of 7 days or more, it is recommended to take a pregnancy test and consult a gynecologist. For other possible reasons for a delay, read the article 10 reasons for a delay in menstruation.

Menstruation after Postinor

After taking Postinor, the nature of menstruation may change. Your periods following Postinor's may be more profuse than usual. See your doctor if your period is too heavy or if it lasts more than 7 days in a row. You may need medication to stop the bleeding.

How often can you drink Postinor?

The use of Postinor several times in one cycle is permissible, but only after consulting a gynecologist.

Frequent use of Postinor increases the risk of menstrual irregularities and uterine bleeding.

What to do if pregnancy occurs despite Postinor's reception?

If pregnancy does occur, then you should immediately consult a doctor. Postinor may increase the risk of ectopic pregnancy, and therefore you may need a thorough examination.

Postinor does not have a negative effect on the embryo, so a normal pregnancy can be saved.

Will I be able to get pregnant after taking Postinor?

A single dose of Postinor, as a rule, does not cause any long-term consequences and does not affect a woman's ability to become pregnant and give birth to a child in the future.

However, the ability to conceive may be reduced in the first few months after taking Postinor, which is associated with temporary hormonal imbalances.

Postinor - apply very carefully!

Postinor is an emergency contraception that can be used after unprotected intercourse or if another method of protection against pregnancy has not worked. This type of contraception is sometimes also referred to as "the morning after". Each pack of postinor contains two round white tablets. Each contains 750 micrograms of levonorgestrel, which is the active ingredient in this drug.

Operating principle

According to experts, progesterone prevents pregnancy in 85% of cases, that is, it is not an absolutely reliable remedy.

It is believed that the active component of postinor prevents the egg from leaving the ovary, or, if it has already left, prevents the fertilization of the egg by the sperm. If fertilization has already occurred, levorgestrel will prevent the ovum from entering the uterine wall.

In the event that the embryo implantation has time to occur, the postinor will not help - he can only prevent the onset of pregnancy, but not interrupt it.

Therefore, the first pill of postinor is recommended to be taken within seventy-two hours after unprotected sexual intercourse. The less time has passed, the more efficiently the medication works. The second pill must be taken 12 hours later (and no more than 16 hours) after the first.

Some experts today advise taking two tablets at once.

In this case, in their opinion, the effectiveness does not change, but the likelihood that a woman forgets to take the second pill or loses it is excluded - which happens quite often.

Contraindications for admission

Do not take this medicine if:

• If you are already pregnant or think you may be pregnant
• If you had a delayed period or if your previous period was unusual
• You've had unprotected sex since your previous period and more than 72 hours have passed since then
• You know that you are allergic to any of the components of the medicine

Also, if you have a history of small bowel disease (such as Crohn's disease), severe liver problems, high blood pressure, diabetes, heart disease, stroke, or breast cancer, talk to your doctor before taking this medicine.

When the effectiveness of the postinor decreases

Postinor may be ineffective for those taking barbiturates and other medicines used to treat epilepsy (for example, primidone, phenytoin, and carbamazepine), medicines for tuberculosis (rifampicin, rifabutin), fungal infections (griseofulvin), drugs that include St. John's wort , as well as the means used for the treatment of HIV-infected.

If, after taking postinor, your periods were unusually weak or, conversely, more intense than usual, consult your gynecologist.

This should also be done if you become pregnant after taking postinor. While there is no evidence that postinor is negatively affecting a child's development, you will have to undergo an especially thorough examination.

Postinor cannot be taken constantly

Postinor cannot be used as a means of contraception all the time. If you take it more than once a month, there is a high probability of menstrual irregularities, since the dose of the hormone contained in the tablets is very high. It should also be borne in mind that, like other contraceptives, with the exception of condoms, it cannot protect you from any sexually transmitted diseases.

About one in four women feel nauseous after taking postinor. If you vomit within three hours after taking the first or second pill, you need to seek advice from your doctor or pharmacist.

For most women, menstruation after taking postinor begins at the expected time, but in some cases they may start earlier or later than the expected time. The bleeding may be longer and more severe than usual.

Sometimes the drug has side effects such as dizziness, lower abdominal pain and fatigue. These symptoms go away after a few days and usually do not require medical intervention.

In no case!
The sooner, the better. The sooner you take the pill, the more likely you are to prevent pregnancy.
Postinor is a solution to the problem with the help of a pill: only 2 pills and you will not need any abortion.
Some people call the emergency contraceptive pill "the next day pill." But this does not oblige you to wait until the next day. You can take the Postinor pill immediately or use it within up to three days after unprotected intercourse (sex), or if you fear that the method of contraception you are using has not justified itself.

How to take POSTINOR?

The package contains 2 tablets.
The first pill must be drunk no later than 72 hours after unprotected sex, the second - 12 hours after the first.

Take Postinor ASAP! The sooner, the better!

The sooner you accept Postinor, the more likely it will be effective. Ideally, you should try to take the first pill within 24 hours of unprotected intercourse, as this is when emergency contraception is most effective.

The effectiveness of emergency contraception depends on the number of hours that have passed since unprotected sex.

When can I take POSTINOR?

POSTINOR is a safe way to prevent pregnancy within 72 hours of unsuccessful contraceptive use or unprotected intercourse (sex), with a low incidence of side effects.
It is very unlikely that you will have any serious or long-term side effects after taking the Postinor tablet. Generally, you can continue your day as usual.

Do not take POSTINOR:

If you are already pregnant, because it will not work, although it will not harm you or your fetus.
If you are allergic to levonorgestrel or other ingredients of Postinor.

Postinor will not protect you from HIV infection and other sexually transmitted diseases (STDs).

How often can POSTINOR be taken?

This is not a regular method of contraception. Try to use it as little as possible, only in an emergency. But never forget: This method has far fewer side effects and health risks than abortion pills or medical abortion.

Strictly speaking, Postinor should not be taken more than once during one menstrual cycle. If Postinor is used more than once during your menstrual cycle, it is likely to disrupt your menstrual cycle.
Emergency contraception does not work as well as regular birth control methods. Your doctor, nurse, or family planning clinic can tell you about long-term methods of contraception that are more effective in preventing you from becoming pregnant.

If you are pregnant

If you are already pregnant, then the Postinor pill simply will not work, and besides, it will not harm either the existing pregnancy or the fetus.
If you think you are pregnant, see your doctor or family planning clinic as soon as possible.

If since your last menstrual period you have already taken the Postinor pill once, and now you find that you are pregnant, do not take Postinor again.

What if I vomit after taking Postinor?

After taking Postinor, some women (about 1 in 100) may have nausea or vomiting.

If you vomit within 3 hours after taking the Postinor pill, you need to take another Postinor pill.

If vomiting has occurred more than 3 hours after taking the Postinor tablet, you do not need to re-take the Postinor tablet.

How do I know if POSTINOR has worked?

You will know that the Postinor pill has worked when you start your next period and your cycle is normal.

When should you see a doctor?

• If your period is more than 5 days late or if it is unusually heavy or scanty.
• If you are still concerned that you are pregnant.
• If you have sudden or unusual pain in the lower abdomen and your period is late.
• If you have any doubts about your health or contraceptive methods, which is most suitable for you.

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 I have not observed any consequences, only yellowish discharge, similar to thrush. Can you please tell me if it is possible that these are signs of pregnancy?
Thanks!

If on the 5-7th day of taking the drug does not begin between menstrual bleeding, you should consult with your 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 using the tablet (after its dissolution and absorption in the intestine). 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 exclude pregnancy. You can read more about the Postinor drug and its effect on the body in our section: Postinor.

Anya asks:

Hello! Immediately after unprotected intercourse, I drank a glass of milk with iodine, after which, within 24 hours, I drank the first postinor pill (the second as instructed), but after 5 days no changes occurred, 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. For more information on this issue, you can get information in the section: Analysis for hCG

Maria asks:

sexual intercourse was two days in a row, and both times they did not use protection, everything inside me, 48 hours after the first time, drank postinor, but it turned out that I got pregnant anyway, could it be?

Unfortunately, this situation is possible, since Postinor is not a 100% effective drug. In addition, the time of taking Postinor is also important - the longer the interval from intercourse to taking Postinor, the less its effectiveness.

Hello! I'm 40 years old. Yesterday at 19.00 there was unprotected intercourse, the very middle of the cycle, a dangerous week. This morning at 10.00 I took Postinor's first pill, 15 hours have passed since the PA. The lower abdomen fell ill, the heartbeat became more frequent, in general, all the signs, the action 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, after 6 days, menstrual bleeding usually begins. It is not the beginning of menstruation, so you do not need to take Tri-regol - wait for the next menstruation and from the first day of the cycle you can use cyclic hormonal contraceptives, if they are prescribed to you by the attending gynecologist.

An unprotected act, after 3 hours I drank 2 Postinor tablets at once (I did not read the instructions, unfortunately), then there was still intercourse during the day. 5 days have passed - slightly bloody discharge. Question - a long-acting drug?

According to the instructions, the emergency contraception Postinor 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.

Elena asks:

A condom broke in the middle of the menstrual cycle. After 4 hours I drank the first pill 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 lack of effect from the use of this emergency contraceptive. Considering that the drug was taken on time, there is no reason for panic.

Elena asks:

We had an unprotected PA on the 8th. He didn't cum inside me, after about 25 hours she drank the first pill and after 12 hours she drank the second. Please tell me should it help? How long should your period 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 medication, spotting usually begins after 6 days, and the next menstruation may come with a delay.
