As the openness of modern society continues to increase, everyone knows that every normal adult will inevitably be exposed to sexual life.

At the same time, it also inevitably means getting involved with contraception.

Nowadays, contraceptive methods are diverse. One of them is the contraceptive injection.

Do you know about contraceptive shots? How are they administered? What are the side effects of contraceptive shots? Can contraceptive shots be used continuously? What precautions should be taken when using long-acting contraceptive shots for women? Below, MomNet Dictionary will provide you with detailed answers~ What is a contraceptive shot? Nowadays, there are countless methods of contraception, but in the gynecological consultation rooms of hospitals, there are still women undergoing abortions. It might be related to the flaws in contraceptive methods. A contraceptive shot is a method that allows women to produce an antiprogesterone hormone through injection, which is an effective contraceptive method. The advantage of this method is its simplicity and convenience; it does not require daily use and can effectively prevent pregnancy. However, contraceptive shots also have some side effects, such as headaches, nausea, and breast tenderness, and some people may develop an allergic reaction to the contraceptive shot. Therefore, the use of contraceptive shots requires guidance from a doctor and attention to the body's reactions.

In sexual life, contraception is one of the most important links.

The contraceptive vaccine is a modern medically developed contraceptive agent, which is a derivative of progesterone and has many different therapeutic applications. One of its uses is to delay estrus and mating behaviors.

The drug can be administered orally by taking 5mg daily for five consecutive days.

To control the libido for a long time, one could take 2.5-5 mg once a week orally.

The contraceptive injection can be used only once and is effective for 3 months.

However, due to its heavy dosage, a single dose equals the consumption of 3 packets of contraceptive pills, which could increase the risk of vascular embolism. It is generally only administered by women in Southeast Asian regions, with Western women rarely using it.

However, the westernization of women's dietary habits has led to an increased risk of vascular thrombosis. Women considering injectable contraceptive methods need to consult a doctor first.

How does the contraceptive needle injection work? In our country, the contraceptive needle we use is called "Single Pregnancy Hormone Contraception." Speaking of single pregnancy hormone, we must already be familiar with its name.

How is the contraceptive injection administered? In many contraceptives, progestins are the main active ingredients.

The contraceptive mechanism of contraceptive needles is to inhibit ovulation and change the intrauterine environment.

The injection is to be given every 2-3 months.

The effect of a single progesterone contraceptive needle lasts for 2 to 3 months at a time, and the user can decide how long the injection lasts (in months).

Its effective rate reaches more than 99%.

The disadvantage is that it takes some time for normal fertility to recover after stopping the contraceptive needle. Usually, other methods of contraception are needed 6 to 24 months after the last injection to ensure the normal development of the fetus in the future.

The side effects of the contraceptive needle, the contraceptive needle also has side effects. Here are some of the side effects of contraceptive needles and solutions.

1. Prolonged menstrual period and shortened menstrual cycle.

Menstrual duration is primarily caused by insufficient progesterone levels and incomplete uterine shedding.

The treatment method involves taking the short-acting contraceptive pill No. 1 or No. 2 for 4 days before menstruation, with one to two tablets taken each day, starting from 5 to 7 days before menstruation. This will ensure that the endometrium sheds normally and the menstrual flow can return to normal.

A menstrual cycle that lasts less than 20 days is considered to be short.

After the administration of long-acting contraceptive injections, if there is a shortening of menstrual periods, one can start taking short-term oral contraceptives (1 or 2) at the 10th day after injection. Each tablet should be taken once daily for 4 to 6 days, which can maintain a menstrual cycle around 28 days.

2. Unregulated vaginal bleeding can be categorized into two types: menstrual afterflow and post-injection contraceptive needle bleeding.

Most are moderate in amount of bleeding, a few are drop-like.

The cause of vaginal bleeding may be caused by insufficient estrogen in the body.

Postmenstrual bleeding, that is, vaginal bleeding occurs several days after menstruation is clear.

At this time, oral contraceptive pills can be taken once daily, with 1 to 2 tablets each time, continuing until the end of this month for injection.

For bleeding dates, no treatment is required.

For vaginal bleeding that occurs a few days after injection of a contraceptive needle, short-acting contraceptive No. 1 or No. 2 can be used once a day, 1 to 2 tablets each time, for several days.

3. Other symptoms A small number of people may experience dizziness, fatigue, drowsiness, nausea and other phenomena after injecting long-acting contraceptive needles.

Generally, symptoms are mild and do not necessitate treatment. In cases where reactions are severe, vitamin B6 can be taken at a dosage of 10 mg three times a day.

Additionally, the administration of long-acting contraceptive injections may cause symptoms such as breast engorgement and rashes.

Can contraceptives be given for a long time? People often unilaterally believe that family planning is birth restriction.

In fact, planning when to conceive is also one of the specific contents of family planning.

The birth of a baby is dependent on favorable timing, location, and conditions. Those who are not yet ready to conceive may opt for contraceptive measures. However, is it possible to continue using contraceptive injections over an extended period? Contraceptive injections belong to a class of steroidal hormone methods of contraception.

In terms of contraceptive efficacy, the success rate of short-acting oral contraceptives is 100%, that of long-acting oral contraceptives is between 96% and 98%, and that of long-acting injectables is 98%.

In terms of safety, intravenous injection is the least safe, followed by subcutaneous injections like contraceptive shots. Both may cause bleeding and infection.

Consistently using contraceptive injections can have significant impacts on the body.

The mechanism of action of steroid contraception involves inhibiting ovulation, altering the physiology of the cervical mucus, modifying the morphology and function of the endometrium, and changing the function of the uterine tubes. However, long-term use can lead to premature ovarian failure and even increase the incidence of breast and cervical cancer.

Therefore, women who have been using hormone contraceptives for a long time should visit the hospital periodically (six months or a year) to undergo examinations including ultrasound and blood lipid, liver function tests (the hormone needs to be metabolized by the liver).

In addition, people who have been given contraceptive injections for a period of time should also have a physical examination to see if there are any abnormalities in their bodies.

Nowadays, very few people come to outpatient clinics to get contraceptives, and doctors do not advocate taking contraceptives.

In the past, economic conditions did not allow it and people were compliant. Taking contraceptives was also a good choice.

However, modern people's compliance is also very poor. In addition, considering the side effects of hormonal contraception, it is recommended to choose other methods of contraception.
