A contraceptive injection is a shot of a progestin, synthetic progesterone. It blocks the woman's own hormonal background and protects her from pregnancy. The injections are given by the doctor in the first 5 days of the natural cycle. Pearl index is high, from 0.3 to 1.4. This method was the hope of women who have more to think about than taking pills and installing coils. After all, an injection can be given once every 12-14 weeks, and just forget about it. But some details have emerged that greatly influenced the popularity of the "injection from children".

Mechanism of action
It is a hormonal drug. It blocks its own ovulation and does not give the body any chance of reproduction. In a woman's injections, the eggs remain in the ovaries, and the natural cycle does not occur. This can be convenient for those who have painful periods, or those who are seriously involved in sports, and for health reasons for future generations do not want to get pregnant yet.
The injection relieves of all the “joy of life” associated with the natural cycle - pains, all sorts of acne-like manifestations, headaches, and sudden swelling disappear. But it can be poorly tolerated, and then the presence of this drug in the blood will cause problems worse than PMS.
What it looks like2
In the first days of the cycle, a woman comes to the doctor, and he gives an injection intramuscularly. This is "oil", that is, an oil suspension. The injection is quite painful and can cause bumps at the injection site. But you cannot massage - this way the content will be “used up” too quickly.
The contraceptive effect occurs 24 hours after administration and lasts for 14 weeks.
Injections of this kind are not sold at the pharmacy. You can get them:
- in the medical center at the gynecologist;
- in an ordinary clinic;
- in family planning centers
Doctors believe that this method of contraception is needed only if a woman cannot tolerate OC, or has serious problems with the gastrointestinal tract, which prevent hormones from simple pills from being absorbed
The drug is prescribed after:
- a comprehensive study of the state of health. Check the health of the kidneys and liver, heart, blood vessels;
- analysis for hormones. The fact is that the injection will only partially suppress its own background. Testosterone production will not stop. Estradiol will also be produced by the body on its own.
With high levels of its own hormones, synthetic progestin can be poorly tolerated - causing fluid retention, causing weight gain, and promoting gradual weight gain.
Important: this is not OK like "Jessa" or "Jeanine", which do not affect weight. All progestins work more like anabolic steroids - they cause weight gain through fluid retention and an increase in blood pressure.
If a woman has problems with blood pressure or hormonal levels, she will be prescribed barrier contraception, not injections.
Pros of contraceptive injections4
This is an outlet for the forgetful. those who cannot take pills due to the fact that they are too chaotic about contraception find real salvation in injections. The pace of life does not affect the ability to protect yourself.
Besides. a woman defends herself against reproductive violence, which is still prevalent in the modern world. Yes, "accidentally" will not work. This is one of the most reliable methods of contraception.
The shot is relatively cheap when compared to the new generation of antiandrogenic pills.
Gynecologists argue quite a lot about such drugs - some say that an adult woman, if she does not want problems with cysts and unwanted pregnancies, should take hormonal contraceptives. Others say that this is an unnecessary measure, and it will only complicate life in the future. Specific cases should be dealt with with the doctor, and not with the help of articles on the Internet.
Cons of injections5
Such means do not allow the widespread domestic practice of prescribing hormonal contraceptives without tests. You will have to take quite a lot - all of them are sexual, and a woman has five of them, STH, thyroid hormones, cortisol. An endocrinologist's consultation is required. additionally.
For those prone to being overweight, the injections will only make the problem worse. The fact is that it is possible to block the “water-pressure” effect of such drugs only with the help of antiestrogens. They are not prescribed to healthy women of childbearing age. If you constantly block estradiol, there is a high risk of causing early menopause, and a serious hormonal disruption.
Therefore, injections are a kind of "special" contraceptive measure, choosing which, a woman really takes a serious step.
Independent attempts to get the remedy, and "deliver" the injection at home for the sake of economy, should be reduced to zero. This remedy is selected only by a doctor. Then the side effects in the form of high blood pressure, weight gain and fluid retention will be reduced to zero. Before re-injection, make sure that there is no pregnancy. Doctors usually recommend using an additional method of protection - condoms at the end of the injection period.
