Diphereline 3.75 with eco-long protocol. Negative phenomena in the treatment of "Diferelin"

Method in vitro fertilization has been giving childless couples a chance to fulfill their dream of a long-awaited child for many years. This technique regulates and controls the processes in the female reproductive sphere at all stages of the protocol. And since hormones “manage” this issue, the drugs are selected taking into account the hormonal background of the woman.

One of the components hormone therapy is the use of Difereline in IVF, reviews of which are extremely controversial. Some women claim that this drug helped them get pregnant, others believe that it was useless, because conception never happened.

Diphereline has antigonadotropic properties. Its task is to block the work of follicle-stimulating and luteinizing hormones in women, as well as testosterone in men.

Such properties of the drug allow it to be used for the following purposes:

Treatment of pathologies: endometriosis and;
Regulation of precocious puberty in adolescents;
Use in complex therapy prostate cancer;
Application in IVF programs.

Participation of Diferelin in the auxiliary reproductive technique it is necessary both at the stage of preparation for artificial insemination, and after the replanting of embryos. Due to the ability of the drug to suppress the production of natural luteinizing hormone, the ovaries begin to intensively “supply” follicles, which is necessary before the puncture procedure.

Difereline in IVF is used for the following purposes:

Stimulate the pituitary gland;
Block the synthesis of LH and FG;
Reduce the amount of androgens and estrogens produced;
Stimulate ovulation;
In the process of embryo transfer according to the protocols.

For in vitro fertilization, the drug is used in the minimum dosage: 0.1 mg. Increased doses of the drug are indicated for the treatment of pathologies: oncology, endometriosis, early puberty.

An injection of Diferelin is given subcutaneously. At the same time, a woman can choose the injection site herself or the doctor will give her recommendations on this matter. You can prick it in the stomach, thigh or under the shoulder blade.

Diphereline in IVF protocols

Diphereline in IVF is a component of both short and long protocols. At the same time, it is prescribed not only before embryo transfer, but also after transplantation has already been done. The drug several times increases the chances of successful fertilization.

The dosage of the drug in the short protocol is insignificant. The injection solution is prepared by mixing the dry powder with a solvent. Injections begin to be given from the second day from the start of the menstrual cycle, in parallel using the hCG hormone. The duration of therapy with Diferelin 0.1 is about 12 injections. HCG needs to be pierced one more day.

Sometimes reproductive specialists prescribe Diferelin and Ovitrel at the same time in the ovulation induction protocol. Ovitrelle is an artificial analogue of human chorionic gonadotropin, it promotes the release of a mature egg from the follicle.

Appointments in a long-term protocol differ in duration and start of treatment. Therapy starts from 21 days from the beginning of the menstrual cycle. The duration of treatment depends on the changed level of estrogen. As soon as their concentration becomes less than 50 pg / ml, parallel stimulation with gonadotropin is prescribed. In most cases, this period falls on the 3rd-5th day of the next menstrual cycle.

The entire treatment process is monitored by ultrasound to determine when dominant follicle will reach sizes of 17-19 mm. The “grown up” dominant signals that the injections need to be stopped. A day later, gonadotropin is canceled and an ovarian puncture is done.

Do not panic if you once missed one injection of the drug. The next injection is made according to the scheme prescribed by the doctor.

If an excessive response has been established with the help of ultrasound diagnostics, Diferelin is discontinued, since the drug can cause ovarian hyperstimulation.

In a long-term protocol, it is permissible to use Diferelin 3.75 as a single dose. The drug is administered on the 21st day from the beginning of the menstrual cycle into the cavity abdominal wall subcutaneously. This dosage allows you to form a depot, with the help of which the hormone gradually penetrates into the body for 20 days. bloodstream. Stimulation of ovulation is carried out using the same scheme as with the daily use of the drug.

After embryo transfer, Diphereline is prescribed after 2-3 days to block the natural work of the ovaries, that is, to increase the chances of an embryo for successful implantation.

With endometriosis

If infertility is caused by thinned endometrium, treatment is carried out according to a long or very long protocol. The main task of therapy is to reduce the area of pathologically thin foci. And having achieved a stable remission, attempt to successfully conceive.

To build up the endometrium before carrying out artificial insemination, a course of therapy with Diferelin is carried out from two months to six months. Once every 28 days, an injection is given that creates a depot. All conditions are created to deeply suppress natural function ovaries. After the endometrium has grown to desired values, spend active stimulation ovulation.

It is important to say that the chances of successful conception against the backdrop of serious endometriosis a little. The fact is that pathology is caused by violations in immune system and in the endometrium. These changes are poorly corrected medications, interfering successful implantation embryo.

Side effects

The negative manifestations of the drug will be different, depending on the stage of therapy.

Doctors conditionally divide the duration of taking the medicine into two stages: the beginning of treatment and the therapy itself. The first 14-21 days of drug administration is the initial cycle of treatment. At this time, patients note such Negative consequences after taking Diphereline 0.1:

Tides;
Dry vagina syndrome;
Pain and discomfort during intimacy;
Osteoporosis;
Decrease or complete absence sexual desire;
Itching of the skin;
Manifestations of urticaria;
Quincke's edema.

During the period of direct therapy, women experience the following side effects from medication:

Increases in blood pressure;
There is nausea, often accompanied by vomiting;
The quality of vision is impaired;
Body weight increases (although many say that, on the contrary, they are losing weight);
There are frequent nervous breakdowns against the background of emotional instability;
In the place where the injection is regularly carried out, there is a persistent pain syndrome;
Frequent headaches, discomfort in muscles and joint tissue are fixed.

The most common side effect in women after treatment with Diferelin 3,75 is the development of amenorrhea (lack of menstruation). Especially "bright" manifest themselves adverse reactions of the body in women with endometriosis.

Even after short protocols, the use of the drug causes a delay in the menstrual cycle. “Belated” periods, which occur 5-15 days later, are considered the norm.

All negative reactions of the body will disappear after the end of treatment, when hormonal background stabilizes.

Drug treatment is contraindicated in the following cases:

Individual intolerance to the components of the drug (allergic reaction, especially urticaria or Quincke's edema);
With the onset of pregnancy;
During lactation.

Despite the fact that there have not been large-scale studies on the dangers of taking Difereline during pregnancy, doctors can, if necessary, use it during this period.

By balancing risk and possible benefit, prescribe the drug to women with such pathologies:

Osteoporosis;
Elevated blood pressure;
Polycystic ovary syndrome.

In the event that pregnancy did not occur after Diferelin therapy, in repeat protocol it is not included, replacing drugs that have a similar effect.

IVF is a type of assistive reproductive technologies used to treat infertility. This method helps couples conceive a child even with severe deviations in the reproductive function.

IVF does not only mean artificial insemination eggs and implantation of the embryo into the uterus, but also the preparation of the woman's body for pregnancy. For this, the patient undergoes examination and treatment, and also applies hormonal preparations. One such remedy is Diphereline. Consider why this drug is prescribed for IVF.

Diphereline is a synthetic analogue of gonadotropin-releasing hormone, which is responsible for the release of follicle-stimulating and luteinizing hormones. Diphereline in the IVF protocol helps to suppress luteinizing hormone and provoke the formation of a large number follicles. Thus, the drug is prescribed to stimulate superovulation before oocyte puncture.

Difereline for IVF is prescribed in a minimum dosage of 0.1 mg. V Large dosages the drug is indicated for oncology, precocious puberty and endometriosis. The drug can be prescribed to men with cancer prostate with metastases.

Application

With IVF, Diferelin can be shown in a short and in a long protocol. In a short protocol, the drug is prescribed in small doses from the 2nd day of menstruation, together with hCG hormone. The course of treatment is no more than 12 doses of the drug, and hCG is finished injecting a day after Diferelin is canceled.

In a long protocol, Diferelin is injected on the 21st day of menstruation, and on the 3rd-5th day an injection of gonadotropin is indicated. Diferelin is canceled in a long protocol when the follicles reach a sufficient size, and gonadotropin is canceled in a day.

If IVF is performed for endometriosis, then a long protocol with Diferelin is prescribed. The drug helps to reduce the manifestations of endometriosis and achieve pregnancy in the protocol.

Many are interested in why Diferelin is prescribed after embryo transfer. The drug is injected on the second day after replanting to suppress ovarian function and increase the chance of successful implantation of the embryo.

Difereline injections are carried out in the subcutaneous fat in the abdomen, at a distance of two fingers from the navel. It is necessary to inject the drug at an angle of 45 degrees, squeezing the skin into a tight fold. It is best if the first injection is performed by a specialist.

Consequences

The instructions for Diferelin indicate that it is contraindicated during pregnancy, this is due to the lack of data on the effect of the drug on the fetus. Animal studies have been conducted which show that the drug congenital deformities does not call. Therefore, Difereline can be used during pregnancy as prescribed by a doctor.

Diphereline significantly increases the chance of pregnancy after IVF, but the drug can cause the following side effects:

decreased sexual desire;
lack of discharge in the vagina;
angioedema, allergic rash;
violations of the digestive tract;
headache;
osteoporosis;
myalgia and arthralgia;
tides.

Thank you

Diferelin is a drug with antigonadotropic action, that is, in essence, it is an antihormone, because it suppresses the production of follicle-stimulating and luteinizing hormones (FSH and LH) in women and testosterone in men. Therefore, Diphereline is used to treat endometriosis, uterine fibroids, premature maturation in boys and girls, prostate cancer and in in vitro fertilization programs.

Names, release form and composition of Diferelin

Currently, Diferelin is produced in the only dosage form lyophilisate for solution preparation . However, there are three varieties of the drug containing different amounts active substance and intended for various ways introductions:

Diphereline 0.1 mg - lyophilisate for subcutaneous injection;
Diphereline 3.75 mg - lyophilisate for intramuscular injection;
Diphereline 11.25 mg is a lyophilizate for intramuscular injection.

In everyday speech, both doctors and patients, for brevity, call the above varieties of the drug, adding numbers to the word "Diferelin" indicating the content of the active substance.

As an active substance, Diphereline contains triptorelin pamoate. However, its content in the lyophilisate is indicated in terms of pure triptorelin. That is, Diferelin 0.1 lyophilisate contains 0.1 mg of pure triptorelin and several large quantity milligram triptorelin pamoate. The content of pure triptorelin in the lyophilizate is indicated specifically for the convenience of doctors, since it is the substance in pure form after release from the salt formed with pamoate, it has a direct therapeutic and pharmachologic effect. And since the severity of the effect depends on the amount of pure triptorelin, it is precisely its content that is indicated as the dosage in all forms of the lyophilisate.

Lyophilisate for subcutaneous injection Diphereline 0.1 contains as excipient only mannitol. And lyophilizates for intramuscular injections– Diphereline 3.75 and 11.25 as auxiliary components contain the following substances:

Polymer of lactic and glycolic acids;
Mannitol;
carmellose sodium;
Polysorbate - 80.

Diphereline is available in cardboard boxes containing lyophilisate vials, solvent ampoules and a syringe with two needles. As a solvent for Diferelin 0.1 is used saline or water for injection. And as a solvent for Diferelin 3.75 and 11.25 lyophilisates, mannitol or water for injection is used, which are placed in the appropriate ampoules.

Lyophilizate Diferelin 0.1 painted in White color and dissolves in the applied solvent, forming a completely transparent solution containing a small amount of suspended particles.

Lyophilizate Diferelin 3.75 it is colored white or white with a cream color, and dissolves to form a white or cream opaque suspension.

Lyophilizate Diferelin 11.25 it is colored yellowish or white, and dissolves to form an opaque suspension, also white or yellowish.

Diphereline - action and therapeutic effects

Diphereline is a gonadotropin-releasing hormone (GnRH) analog produced by the hypothalamus. GnRH affects the pituitary gland, which, in turn, produces tropic sex hormones, such as follicle-stimulating, luteinizing, testosterone, etc. And these tropic hormones regulate the functioning of female and male reproductive organs, for example, ovaries, uterus, testicles, prostate gland. Diphereline reduces the production of tropic pituitary hormones, respectively, reducing the activity of the ovaries and testicles in the synthesis of sex hormones. Thus, the therapeutic effects of the drug are due to the effect on the level of production of the genital organs by the ovaries of women and the testicles of men.

Since sex hormones have an impact on the development and course of certain pathologies, the use of Diferelin, which reduces their production, is justified in the complex therapy of diseases provoked by elevated levels estrogen in women and testosterone in men. This effect Diphereline is called antigonadotropic and antitumor.

So, when using Diferelin during the first 2-3 weeks, stimulation of the pituitary gland is noted, but then, throughout the rest of the course of therapy, the drug suppresses the synthesis of follicle-stimulating and luteinizing hormones, and, accordingly, the production of both androgens and estrogens decreases. The maximum severity of the antiandrogenic effect is achieved at 3 weeks from the start of Diferelin use and persists throughout the rest of the course of treatment.

Due to the stimulating effect of Diphereline during the first 2-3 weeks of use, it is used to stimulate ovulation and transfer of a fertilized embryo in in vitro fertilization protocols.

Diphereline in the treatment of endometriosis, as a rule, causes amenorrhea (artificial menopause, lack of menstruation). However, after stopping therapy, menstruation is restored over a certain period of time (from 1 to 12 months), the specific duration of which depends on the individual characteristics of the woman's body. Most often, the first ovulation occurs by the end of the second month, counting from the last injection of Diferelin, and menstruation begins, respectively, after 2.5 - 3 months.

If endometriosis recurs after one course of therapy with Diphereline, then after 6 to 12 months, if necessary, you can be treated again. However, with relapses of endometriosis, usually do not resort to repeated courses treatment with Diferelin, but use other drugs (for example, Buserelin, etc.) or cauterize the foci during laparoscopic surgery.

Diphereline for precocious puberty one dose is administered every 28 days. One dose for children weighing more than 20 kg is 3.75 - that is, one full bottle of lyophilisate. And one dose for children weighing less than 20 kg is only 1.875 mg, that is, half of one vial of lyophilisate. The duration of therapy is determined by the doctor and depends on the rate of normalization of the condition.

Half dosage for children weighing less than 20 kg is prepared in the following way: collect the entire volume of the solvent and add to the vial with lyophilizate. The entire volume of the lyophilisate is dissolved, but only half of the resulting suspension is drawn into the syringe. It is very simple to understand how much half is - divide the volume of the ampoule with the solvent into two. For example, in a sealed ampoule 2 ml of solvent, then half is 1 ml. That is, all 2 ml of the solvent are added to the vial with the lyophilisate, mixed well, but only 1 ml of the finished suspension is taken into the syringe for injection.

Diferelin at female infertility enter one whole vial (3.75 mg each) on the second day of the menstrual cycle. Treatment is continued for a period of time determined by the doctor.

Diphereline for uterine fibromyoma the first time is administered during the first five days of the next menstrual cycle. This means that after the start of the next menstruation, it is necessary to enter the first dosage of Diferelin within five days. In the future, the drug is administered every 4 weeks (28 days) for 3 months. Each time, one full vial of Diferelin is administered, that is, 3.75 mg of the active substance.

During treatment uterine fibroids Diferelin in a woman, as a rule, amenorrhea occurs (cessation of menstruation). This has a positive effect on general condition women, because she does not experience blood loss during bleeding and heavy menstruation. After stopping the use of Diphereline, menstruation is restored within a few months. During the entire period of use of the drug, it is necessary to regularly conduct ultrasound of the pelvic organs, monitoring the rate of reduction in the size of the uterus and fibroids. If the uterus is shrinking faster fibroids, it is urgent to perform an operation, since such a situation is fraught with the development of sepsis.

Diferelin 11.25 - instructions for use

This variety of Diphereline is also a depot form, and a single injection of a vial of 11.25 mg of the active substance provides it therapeutic activity during three months. That is, for the treatment of Diferelin 11.25, one vial is administered once every three months.

For prostate cancer in men and endometriosis in women, Diferelin is administered in one vial every three months. The duration of therapy for prostate cancer depends on the rate of improvement and involution of education. And the duration of treatment for endometriosis is 3-6 months, since the drug is not recommended for more than six months in a row.

The first injection of Diphereline in men can be made at any time, and in women with endometriosis - only during the first five days of the next menstrual cycle.

Overdose and interaction with other drugs

Interactions of Diferelin with other drugs and cases of overdose have not been identified.

The drug does not affect the ability to control mechanisms, so during the course of therapy you can drive a car.

Application during pregnancy

Difereline is contraindicated for use during pregnancy. This means that if a woman is already pregnant, then it cannot be used.

However, the drug is used to stimulate ovulation, and many women became pregnant after several injections, but without knowing it, they continued to use Diphereline. Such cases made it possible to establish precisely that the drug does not negative impact on the fetus, does not provoke the development of congenital malformations and does not increase the risk of miscarriage. This allows us to say that Diferelin is not dangerous for the fetus, but further study of its properties is necessary.

After Diferelin - general condition

Diphereline reduces the production of sex hormones in men and women and, in fact, introduces them into a state of artificial castration. That is, under the influence of Diphereline, a hormonal background is created in a man, like a eunuch (castrato), and in a woman - like with menopause or both ovaries removed. Naturally, entry and exit given state accompanied by neuro-vegetative, endocrine-metabolic and psychological disorders and numerous complaints.

After completing the course of using Diphereline, the hormonal background is gradually restored, but until the balance of hormones returns to normal, a person may be disturbed by headaches, irritability, fatigue, hot flashes, sweating, changes in body weight, fever, depression and other complaints.

The condition is completely normalized, usually within one and a half months after the end of the last injection. That is, normalization of the condition can be expected 4.5 months after the last injection of Diferelin 11.25 and 2.5 months after Diferelin 3.75. During this period, sexual and reproductive function is fully restored in men and women and libido is normalized.

Menstruation and pregnancy after Diferelin

Ovarian function is usually fully restored approximately 1.5 months after the end of the last injection of Diphereline administered for the treatment of endometriosis. This means that menstruation should be expected approximately 4.5 months after the last injection of Diferelin 11.25 and 2.5 months after Diferelin 3.75. It is during this period that the first menstruation usually occurs after Diferelin, which can be different. However, menstruation is usually painless or painless and scanty. By the second menstrual cycle, menstruation takes normal character. However, the first menstruation, which began 4 to 6 months after the end of the last injection of Diferelin, is also considered the norm.

Since the first ovulation usually occurs a month after the end of the last injection of Difereline, if you do not want to become pregnant, you should start using contraceptive methods in advance. It is recommended to start using contraceptive methods from the 15th day after the end of the last injection of Diferelin.

When using Diphereline 0.1 in short and long IVF protocols, menstruation, as a rule, is delayed by several days - from 5 to 15. In some cases, menstruation stops altogether, and in this case, the doctor determines the tactics of further stimulation solely on the basis of test results.

Diphereline - side effects

Side effects of Diphereline vary at the beginning and during treatment. The first 2-3 weeks of Diferelin administration are considered to be the beginning of treatment. And all the subsequent time during which Diferelin is administered is considered a therapy process.

prostate cancer of locally advanced type or metastatic;
when registering premature puberty in boys and girls;
with genital and extragenital endometriosis - the appearance of atypical cellular structures (endometrial cells) in the peritoneum, ovaries, fallopian tubes;
