Contraceptive cream contains phenylmercuric acetate and ethylparaben, which is a translucent paste. Its function is to kill sperm and prevent them from entering the uterine cavity.

The application method can be used alone or in combination with other contraceptives:

1. Before sexual intercourse alone, inject about 5 ml of contraceptive ointment into the deep vagina with an extruder.

2. Before putting the vaginal diaphragm, squeeze contraceptive ointment on the convex and concave sides of the vaginal diaphragm vault and the spring ring on the edge of the diaphragm, spread the ointment evenly with your fingers, and then put it into the vagina;

3. Applying some contraceptive ointment on the top of the condom can improve the contraceptive effect. Generally speaking, the contraceptive effect of this ointment is poor when used alone, but it is better when used in combination with other contraceptives.

How do women choose birth control pills?

All married women of childbearing age who are healthy and have no organic diseases of important organs can temporarily use contraceptives for birth control. But there are many kinds of contraceptives. How to choose according to your actual situation?

(1) If the husband and wife are together and live a regular life, they can take short-acting oral contraceptives, such as 1 and No.2 oral contraceptives; Take one tablet every day from the fifth day of menstruation for 22 days.

(2) When the husband and wife are together, their lives are irregular and they can't insist on taking it orally every day. You can choose a long-acting oral contraceptive, such as compound 18 norethindrone, once on the fifth day of menstruation, twice every 20 days, and once a month thereafter, one tablet at a time.

(3) The husband and wife are separated. You can take birth control pills when visiting relatives, such as visiting relatives tablets 1. Take one tablet 8 hours before sexual intercourse, then take 1 tablet every night until the end of visiting relatives and take it again the next morning. Not suitable for long-term use.

(4) If other contraceptive methods are found to be ineffective, or the victim is raped, the morning-after contraceptive, such as diethylstilbestrol 50 mg, can be taken within 24 hours for 5 consecutive days.

(5) Women who suffer from gastrointestinal discomfort caused by oral contraceptives can choose contraceptive needles.

How to take short-acting contraceptives?

Although there are several kinds of short-acting contraceptives, they are taken in exactly the same way, that is, from the first day to the fifth day of menstruation (never from the fifth day after menstruation), take 1 tablet every night for 22 consecutive days. In case you lose your clothes, you should make them up in time the next morning. You can take the medicine naturally for 1-3 days after stopping taking the medicine, and start taking the medicine on the fifth day for the next week. If you still can't take the medicine for 7 days after stopping taking the medicine, you should also start taking the medicine for the next cycle. If you can't menstruate for 3 months in a row, you should stop taking drugs and use other contraceptive measures, otherwise you may get pregnant once ovulation resumes. If you are not pregnant after ovulation, the endometrium will fall off and menstruation will occur. In other words, ovulation occurs before menstruation, and if no measures are taken, you may get pregnant before menstruation.

4. The benefits of oral contraceptives

Nowadays, oral contraceptives have become an indispensable medicine in people's lives, and with the continuous improvement of contraceptives, oral contraceptives have the following advantages:

First, the quality is improved and the side effects are reduced.

Today's contraceptives are very different from the early ones, with the estrogen content reduced by 80% and progesterone reduced by 90%. Today's contraceptives no longer have many side effects, such as weight gain, thrombosis and heart disease. Of course, birth control pills are not as harmless as bottled water. A few women with hypertension or diabetes may also have symptoms such as nausea, menstrual cycle disorder or mood swings. But in general, modern contraceptives are basically harmless to women's health.

Secondly, menstrual flow can be effectively controlled.

Oral contraceptives can slowly release estrogen and progesterone, and prevent the human body from producing these two hormones, thus preventing ovarian ovulation to achieve the purpose of contraception, making the menstrual cycle regular, reducing menstrual flow, and alleviating premenstrual syndrome such as abdominal distension and breast pain.

The third is to make the skin smoother.

Several hormones contained in birth control pills can also make skin smoother, which is very beneficial to improve skin health, which has been proved by many experiments.

The fourth is to reduce the possibility of cancer.

The most unexpected function of contraceptives is to prevent ovarian cancer and endometrial cancer. Taking birth control pills can reduce the risk of ovarian cancer in women by 40%, and the reduction rate is as high as 80% after long-term use. It can also inhibit colorectal cancer.

Fifth, it is harmless to fertility.

So far, it has not been found that contraceptives have anything to do with fetal development problems or congenital defects. Contraceptive pills can even protect women's fertility, because the hormones they release can prevent pelvic inflammatory disease, endometriosis and benign ovarian cysts caused by tubal trauma caused by reproductive tract infection. However, for safety reasons, doctors still advise women to get pregnant after taking birth control pills for three months.

Sixth, improve women's mental outlook.

The biggest advantage of taking birth control pills is that it can make women feel better, have a better menstrual period and have a better month, because there is no need to consider the fear of pregnancy.

Seventh, it can improve the quality of sexual life.

Many studies have found that women who take birth control pills have more frequent sex life than women who don't, and the effect is better, because menstrual flow is reduced, premenstrual syndrome is alleviated, and sexual impulse is stronger.

Eighth, it has played a role in delaying aging.

Contraceptives can maintain a balanced estrogen level, which can minimize this effect. Estrogen can also strengthen women's bones. Many studies have shown that long-term use of contraceptives can delay or even prevent bone loss in women after the age of 50.

Ninth, there is an emergency contraceptive method.

Oral contraceptives also have a special purpose, that is, taking two pills within 72 hours after unprotected sex can prevent ovulation and implantation of fertilized eggs, and its effective rate can reach 75%.

The tenth is to choose more.

At present, there are many kinds of birth control pills. Even if taking one contraceptive pill will have some side effects, you can choose to take another contraceptive pill, which can also have a good effect. Considering other contraceptive measures, oral contraceptives provide another choice for family planning and reproductive choice.

6: What should I do if I miss birth control pills?

When using short-acting contraceptives, it is required to take 1 tablet every night from the fifth day of menstruation, and take 22 tablets continuously, without omission. If you miss it, the estrogen level in the blood will drop, and there will be vaginal bleeding, which is called breakthrough bleeding. The incidence of breakthrough bleeding is closely related to missed service. 1 time missed diagnosis, and the incidence of bleeding was 15%. The incidence of bleeding after two missed diagnoses was 20% ~ 60%. If the diagnosis is missed for three times, the incidence of bleeding is 60% ~ 100%. Therefore, you should avoid missing the medicine during taking the medicine. If there is any omission, take 1 tablet in time the next morning. If there is more bleeding than menstruation, you should stop taking medicine, count your menstruation, and start taking medicine for the next cycle on the fifth day. Missed service may not only lead to bleeding, but also affect the contraceptive effect. Therefore, in the process of taking medicine, we must attach great importance to it ideologically. In order to avoid missing medicine, the medicine should be placed in a convenient place beside the bed, and the husband has the responsibility to remind him at any time.

7: Oral contraceptives

Most people will have no problem taking birth control pills, but a few people may have some side effects because of their physical relationship. However, it doesn't matter, they will be safe with a little treatment.

Early pregnancy-like reactions, such as nausea, vomiting, picky eaters, etc. After taking oral contraceptives, it is a temporary phenomenon that estrogen in contraceptives stimulates the gastric mucosa. When the gastric mucosa adapts to this stimulus, it will become a habit. People with strong reaction need to take some drugs to control this reaction, such as vitamin b6 and anisodamine, or eat some foods rich in vitamin b6, such as lean meat, liver and egg yolk, which can shorten this uncomfortable process.

Menstrual disorders After taking contraceptives (especially short-acting contraceptives), individual people may have menstrual disorders, and those who are mild do not need treatment. Generally, those who have been menopausal for more than two months should switch to other contraceptive measures. At the same time, they should take 50 mg of chlorpheniramine every day for 5 days, then take it for 5 days in the next month, and then take it for 3 months to get better.

After missing the contraceptive pill for some reason, uterine bleeding may occur. If it happens in the first half of menstrual cycle, you can take ethinylestradiol 0.05 ~ 0. 15 mg until you finish taking 22 tablets; If it happens in the second half of the menstrual cycle, you can take 0.5 ~ 1 capsule every night until you finish taking 22 capsules. It is best to eat some iron-rich foods such as animal liver and blood.

Some women with pregnancy spots will have pregnancy spots after taking birth control pills. In fact, this stain is not unique to pregnancy, and it will also appear when the growth rate of estrogen and progesterone levels in the body is high. For this stain, as long as the contraceptive is stopped, it will gradually fade away. If you can add some fresh vegetables and fruits rich in vitamin C to your diet, such as vegetables, Chinese cabbage, celery, tomatoes, oranges, oranges and so on. The stain will disappear faster.

8. How to keep oral contraceptives?

Women who use oral contraceptives should be properly kept to prevent accidents such as being affected with damp, deterioration, breakage and accidental ingestion.

Birth control pills are mostly sugar-coated tablets, and the effective ingredients of birth control pills are in the sugar coating. Therefore, birth control pills should be placed in a cool and dry place to prevent them from being affected by heat and moisture, otherwise the sugar coating outside the pills will deliquesce or dry out, thus affecting the contraceptive effect.

Birth control pills have a certain sweetness, and some birth control pills are bright in color, which are easy to be taken by children, causing liver damage or false precocity. Therefore, when there are children at home, birth control pills should be placed where children can't get them to prevent them from taking them by mistake.

9. Precautions for oral contraceptives

The active ingredients of oral contraceptives are all on the sugar coating on the outer layer of the tablets. Check whether the tablets are complete when taking medicine. If you find that the tablets are wet and the sugar coating falls off, you can't take them anymore.

A few first-time users will have nausea, vomiting, dizziness and weakness, so there is no need to be nervous. If you insist on taking the medicine, the symptoms will gradually ease and disappear. Taking vitamins C and b6 can also relieve symptoms. You can also eat pickles, ginger or drink strong tea to help relieve discomfort.

If the husband or wife goes out during medication, the wife should still take 22 tablets to avoid contraceptive failure or disrupting the normal menstrual cycle. Take 1 tablet within 24 hours if missed.

A drug should not be taken for a long time and should be used alternately with contraceptives.

Avoid taking certain drugs during medication, otherwise contraception may fail. Common drugs that may lead to contraceptive failure are oxytetracycline, tetracycline, chloramphenicol, furan, phenytoin sodium, phenobarbital and rifampicin.

10: It is not suitable for pregnancy after stopping using contraceptives.

Contraceptive pills are synthesized by low-dose estrogen and progesterone, and their main function is to inhibit ovulation; Change the nature of uterine mucus to prevent sperm from entering the uterus; Hinder the implantation of fertilized eggs, etc.

Generally speaking, if you stop using contraceptives for one month, the ovary can restore ovulation function.

Does contraceptive have an effect on the fetus? For this reason, scientists in many countries have done a lot of research, and there is no conclusion yet. Most scientists believe that the contraceptive pill has no obvious toxic effect on the fetus because of its small dose. There is no difference in the incidence of pregnancy and congenital malformation between women who stop taking contraceptives and women who do not take contraceptives. However, some people think that estrogen or progesterone can cause fetal genital abnormalities (female fetus is positive, male fetus is negative), cleft palate and spinal, anal and cardiac malformations can occur. Therefore, from the perspective of eugenics, women who take contraceptives for a long time should have an abortion if they can't. Women who take birth control pills and want to have children should get pregnant after stopping using them for half a year.

1 1: Can I have my teeth extracted by taking birth control pills?

I'm afraid everyone knows not to pull teeth during menstruation, but many people don't know the relationship between pulling teeth and taking birth control pills.

There is a disease called dry socket, which refers to the dissolution of blood clots in alveolar fossa after tooth extraction and the exposure and necrosis of alveolar bone. People suffering from this disease often have persistent severe pain radiating to the ear and temporal region within 3-5 days after tooth extraction, local lymph nodes are swollen and tender, and symptoms such as limited mouth opening, loss of appetite, low fever, general malaise and poor sleep can also occur. Surprisingly, after the extraction of impacted mandibular wisdom teeth, the incidence of dry socket increased from 0.5% to 68.4% for various reasons, including oral contraceptives.

In order to confirm the relationship between oral contraceptives and dry socket, a doctor selected 78 healthy women, aged 17~37 years old, with impacted wisdom teeth on both sides but no acute inflammation. He divided 39 people who didn't take oral contraceptives into one group and the other 39 people who took oral contraceptives into the second group. One impacted wisdom tooth was pulled out in menstrual cycle 1 day, and the other impacted wisdom tooth was pulled out in menstrual cycle 14 day. All the operations were performed by the same doctor, using the same anesthetic and according to the standard method. On day 1, day 4 and day 7 after tooth extraction, the patients were examined for dry socket. Results: Dry socket occurred in 28 teeth of 27 patients, including 65438 08 teeth in the oral contraceptive group, especially in the menstrual cycle of 65438 0 days. The incidence of dry socket was only 12.8% in the group without using contraceptives, and the incidence of dry socket was the least on the first 14 day of menstrual cycle. Among 27 cases of dry socket, 17 cases had their teeth extracted on the first 1 day of menstrual cycle. Visible relationship is very close.

The reason why oral contraceptives increase the incidence of dry socket may be that contraceptives increase fibrinolytic activity and blood clots are destroyed, while the reason why tooth extraction increases the incidence of dry socket on the 1 day of menstrual cycle is that the precursor activator of plasminogen in saliva increases at this time, reaching the maximum. The wound comes into contact with saliva, and the blood clot is destroyed prematurely, which affects the healing. This is consistent with the situation before, during and after menstruation.

This is true for tooth extraction, and so is surgery in oral cavity and other parts. Therefore, female friends should not only avoid the menstrual period, but also avoid the oral contraceptive period.

12: Contraceptive drugs can prevent intestinal cancer.

An Italian researcher said on Monday that estrogen in birth control pills can help women prevent intestinal cancer. A review covering 20 international studies shows that the use of oral contraceptives is negatively correlated with the incidence of intestinal cancer.

Researchers believe that using the anti-cancer properties of contraceptives, new cancer treatment methods may be developed in the future.

Researchers believe that estrogen in contraceptives can reduce the risk of colon cancer by reducing cholic acid associated with colon cancer. It can also reduce the content of igf- 1, another hormone that promotes cell division in blood.

Because igf- 1 causes cells to divide too fast, the high content of igf- 1 in human body may induce cancer. Cancer occurs when the division of diseased cells is out of control and cannot self-destruct.

Scientists have found in laboratory research that estrogen can inhibit the growth of colon cancer cells.

La vecchia's analysis of previous studies shows that the risk of colon cancer in women who take contraceptives is reduced by 18% compared with those who don't.

13: which women are not easy to take birth control pills?

1. Patients with hypertension and hypercholesterolemia.

2. Patients with heart, liver, gallbladder and kidney diseases.

3. Women with children under two years old after giving birth.

4. People with diabetes or people with a family history of diabetes.

5. Suspected to be pregnant and have jaundice before pregnancy.

6. Irregular vaginal bleeding or less than one month after operation.

7. People with blocked blood vessels in legs and lungs. Patients with migraine or headache caused by vascular diseases.

8. Breast, reproductive organs and liver are suspected of cancer, or have a family history of breast cancer.

9. Epilepsy and mental illness.

10. Shortening of lower limbs or severe disability below the knee.

In addition, women over the age of 35 and those who are addicted to alcohol and tobacco should also use female oral contraceptives with caution.

14: Why can't you abuse contraceptives?

In the busy farming season, some rural women do not take contraceptives according to prescriptions for a long time in order to participate in labor, and then stop taking them at the end of the busy farming season. Is this good? Judging from the immediate interests, it seems to be beneficial. I haven't had my period for the time being, which neither affects my work nor is it clean and neat. In fact, doing so is harmful to your health. Because long-term continuous medication will inhibit ovarian function, leading to irregular menstruation or amenorrhea. Irregular menstruation and excessive bleeding can also cause anemia, infection and general malaise. Therefore, this habit of using birth control pills must be corrected, otherwise it will be harmful to the body.

There are also some women who take birth control pills to visit relatives, but they don't take them according to the regulations. They mistakenly believe that all medicines for visiting relatives are taken once in the same room. In fact, only the No.53 contraceptive pill can be eaten like this. If you use other contraceptives in this way, it will often lead to contraceptive failure or irregular menstruation. Therefore, when taking birth control pills, we must make clear the model, function and taking method of the drugs to ensure the contraceptive effect and health.

15: Oral contraceptives are far more than contraception.

In fact, the role of oral contraceptives is far more than contraception, and it has many little-known protective effects on women's health. Many studies show that most women can take birth control pills without worrying about short-term side effects or long-term health effects.

Reduce the possibility of ectopic pregnancy. Ectopic pregnancy (ectopic pregnancy, usually in the fallopian tube) can lead to severe abdominal pain and abdominal bleeding, and even life-threatening. It is one of the most common dangerous gynecological diseases for women of childbearing age, and often requires surgical removal of the ovum tube or ovary. Compared with women who don't take oral contraceptives, the probability of ectopic pregnancy in women who take oral contraceptives can be reduced by 90%.

Reduce the incidence of ovarian cancer. Ovarian cancer is not easy to be found in the early stage, and it is the tumor with the highest malignancy, the worst curative effect and the highest mortality rate among gynecological cancers. The protective effect of oral contraceptives on ovarian cancer was first discovered in 1977 and has been confirmed by at least 10 trials. Oral contraceptives can reduce the possibility of ovarian cancer by 50% on average, and it will decrease with the extension of medication time.

Reduce the incidence of pelvic inflammatory disease. Severe pelvic inflammatory disease can lead to ectopic pregnancy and infertility. Taking oral contraceptives can change cervical mucus and prevent inflammation from spreading. Women who take oral contraceptives are less likely to suffer from pelvic inflammatory disease.

Ensure a regular menstrual cycle. And the time when menstruation begins can be controlled. For example, holidays, honeymoons, exams, competitions or weekends can avoid menstrual bleeding; Taking medicine can also relieve premenstrual tension symptoms; Eliminate pain during ovulation.

Delay aging. With the increase of age, ovarian function begins to decline, and the level of estrogen becomes more and more unstable, so that women will have increased menstrual flow, prolonged menstrual period, more emotional fluctuations similar to menopause syndrome, and even hot flashes. Taking high-dose contraceptives can provide stable estrogen levels and reduce this effect. Other studies have shown that estrogen released by oral contraceptives can also delay or even prevent bone loss in women after the age of 30.

16: Contraceptive drugs should not be mixed.

There are three kinds of oral contraceptives: long-acting, short-acting and visiting relatives. Generally speaking, it is a single pill. If you are worried about contraceptive failure, mix long-acting contraceptives with short-acting contraceptives, or take long-acting contraceptives as short-acting pregnancy drugs, and the consequences are very serious.

Because long-acting contraceptives generally only use 1 tablet every month, while short-acting contraceptives take 1 tablet every day from the fifth day of menstruation for 22 days. If long-acting contraceptives are taken together with short-acting contraceptives, or long-acting contraceptives are taken as short-acting drugs, their dosage will increase, which will cause liver function damage and jaundice, and it often takes more than 1 year to restore health.

Therefore, long-acting and short-acting contraceptives should not be mixed, and should be taken separately.

17: Oral contraceptives are easy to induce cervical cancer.

According to a newly published study on the etiology of cervical cancer, it is easy for women to induce cervical cancer by using oral contraceptives.

The cervix is a glandular organ located at the bottom of the uterus. One of the most common causes of cervical cancer is human herpesvirus infection. Human herpesvirus is a virus that can be transmitted through sexual contact. At present, it has been found in all invasive cervical cancers. In developed countries, cervical cancer can usually be found by ordinary medical examination. Because cervical cancer can generally be found in the early stage and treated in time, the cure rate of this cancer is also relatively high. Nevertheless, cervical cancer is still one of the main causes of cancer death in many countries in the world.

At present, the main research on preventing cervical cancer in the world focuses on analyzing which factors will increase the risk of cervical cancer. British scientists evaluated the results of 28 clinical studies conducted by12,500 women to determine whether there is a certain link between the use of oral contraceptives and cervical cancer. The evaluation results show that compared with women who have never taken oral contraceptives, the probability of cervical cancer in women who have used oral contraceptives for less than five years is 10%, and the probability of cervical cancer in women who have used oral contraceptives for five to nine years is 60%. If the service life of oral contraceptives is extended to more than 10 years, the incidence of cervical cancer can be as high as 120%.

In addition, the researchers also found that women with human herpes virus plus taking oral contraceptives will increase the risk of cervical cancer by 90%. Therefore, the researchers said that women who like to use oral contraceptives should follow the doctor's advice before taking them, because everyone's specific situation is different. Women who use oral contraceptives for a long time should have regular cervical cancer examinations.

18: What are the female vaginal contraceptive?

Vaginal contraceptives are drugs that are put into the vagina to kill sperm to achieve contraceptive purposes. There are four kinds of commonly used vaginal contraceptives: vaginal contraceptive membrane, vaginal contraceptive tablet, contraceptive suppository and contraceptive cream.

How to use female vaginal contraceptive membrane?

Vaginal contraceptive tablets are an acidic spermicide.

Usage: Wash your hands first, push the tablets into the deep vagina with your fingers, cling to the cervix, and have sex after 5- 10 minutes. If the contraceptive is placed in the vagina for more than half an hour after sexual intercourse, or does not ejaculate for half an hour after sexual intercourse, it needs to be placed again 1 tablet to ensure the contraceptive effect. 6-8 hours after sexual intercourse, you can wash the vulva with warm water, not in advance, so as not to affect the curative effect.

Women with vaginitis should not use it.

How to use female vaginal contraceptive membrane?

External use membrane, also known as external use alkanol contraceptive membrane, has strong spermicidal effect, and the contraceptive effective rate is over 96%.

Contraceptive membranes can be used by both men and women.

Before sexual intercourse, fold a contraceptive membrane twice to reveal its original size 1/4, or knead it into a soft ball, and then push it with your fingers near the vagina and cervix. If you feel the medicine film sticking to your fingers, you can turn around in your vagina. After removing the medicated membrane from your fingers, push it deep into your vagina. Put it in for 5 minutes, and the medicine film will deepen and you can have sex.

How to use female vaginal contraceptive suppository?

When in use, wash your hands, take 1 contraceptive suppository, peel off a layer of tin foil or wax paper, and push it slowly (with the tip forward) into the vagina with your fingers. After 5- 10 minutes, you can have sex after the contraceptive suppository is completely dissolved. If you don't have sex for half an hour after putting the contraceptive suppository into the vagina, you should take 1 pill to avoid contraceptive failure. 6-8 hours after sexual intercourse, the vulva can be washed with warm water.

Suppositories are oily and easy to damage rubber, so they should not be used with vaginal septum and condom at the same time.

Suffering from vaginitis, uterine prolapse, severe cervical erosion, vaginal relaxation should not be used.

How do women use external contraceptive cream

Before sexual intercourse, screw the contraceptive cream syringe on the contraceptive cream nozzle, press the medicine tube to squeeze the ointment into the syringe (if there is a scale on the contraceptive cream syringe, squeeze the ointment into the scale, or squeeze it into the tail of the syringe), the woman lies on her back with her legs apart, slowly insert the syringe containing the ointment into the deep vagina, and then take out the syringe for sexual intercourse. If you don't have sex for too long, you need to inject 1 time, otherwise it will lead to contraceptive failure.

19: How to take long-acting and short-term contraceptives?

Long-acting oral contraceptives are composed of synthetic progesterone and long-acting estrogen. Taking 1 time can prevent contraception 1 month, and the success rate is over 98%. There are three common long-acting contraceptives:

1, compound 18 norethindrone

Also known as compound long-acting 18A, it contains 3 mg of ethinylestradiol and 0/8 mg of norethindrone. For first-time users, take 1 tablet on the 5th and 25th day after menstrual cramps, and take 1 tablet every time, and then take 1 tablet on the same day as the second medication every month. If a woman menstruates on May 2nd, take 1 tablet on May 7th, 1 tablet on May 27th, and take L tablets on the 27th of each month.

2. Compound ethinylestradiol

It contains 3.3 mg of ethinyl estradiol and 15 mg of chlormadinone. The administration method is the same as that of compound 18 norethindrone.

3. Compound 16 methylene chloride progesterone (hereinafter referred to as compound 16 times a)

It contains 3 mg ethinylestradiol, 16 mg methylene chloride progesterone, 10 mg. The administration method is the same as that of compound 18 norethindrone. Or take 1 tablet from the fifth day of menstrual cramps, take the second tablet on the 20th day after taking 1 tablet, take the third tablet every 20th day, and then take 1 tablet every 28th day. If a woman menstruates on May 2nd, take 1 tablet on May 7th, take the second tablet on May 27th, take the third tablet on June 16, and take 1 tablet every 28 days thereafter.

If women who take short-acting contraceptives want to switch to long-acting contraceptives, they can take 1 long-acting contraceptives the day after taking 22 short-acting contraceptives in the scheduled menstrual cycle, and then take them according to the use method of long-acting contraceptives. If you plan to stop using long-acting contraceptives, first take 1 or No.2 short-acting contraceptives (see short-acting contraceptives for taking methods) and take 2 ~ 3 menstrual cycles as a transition to prevent menstrual disorders. It is best to take medicine about half an hour after lunch every time. Women who work at night shifts can take medicine after night meals, so that in case of drug reaction, they can relieve the discomfort during sleep. It is normal to menstruate once every 10 ~ 15 days after taking the long-acting contraceptive for the first time. After taking the long-acting contraceptive, the first two menstrual cycles are shortened, and the menstrual cycle can turn normal after the third time.

Short-acting oral contraceptives are composed of synthetic estrogen and progesterone. There are four kinds of oral short-acting contraceptives commonly used in China:

1, the number of the pill. 1: Also known as compound norethindrone tablets, it contains ethinylestradiol 0.035 mg and norethindrone 0.6 mg.

2. Contraceptive pill No.2: also known as compound progesterone tablet, contains ethinylestradiol 0.035 mg and megestrol acetate 1 mg.

3. Contraceptive O: contains ethinylestradiol 0.035 mg, norethindrone 0.3 mg and megestrol acetate 0.5 mg.

4. Short-acting 18A: also known as compound 18 norethindrone tablets, containing ethinylestradiol 0.03 mg and 18 norethindrone 0.3 mg.

Management method:

The above four short-acting contraceptives have the same effect, and the use method is the same. You can take any one.

The specific administration method is as follows:

Take medicine from the fifth day of menstrual cramps (even if the menstruation is not clean that day), take 1 tablet every night for 22 days continuously, which can prevent contraception 1 month. Generally, menstrual cramps occur on 1-3 days after drug withdrawal, and then continue to take the above methods for 22 days from the fifth day of menstrual cramps. This is repeated month by month and can be taken continuously for many years.

Pay attention to the following points when taking medicine:

1. Take the medicine strictly according to the regulations. No matter whether menstruation is clean or not, it must be taken on the fifth day of menstruation. If you take it late, you can't inhibit ovulation and affect the contraceptive effect.

You must take the medicine continuously for 22 days without interruption. If you forget to take medicine one night, you must take 1 tablet the next morning. If you don't take it or stop taking it halfway, it will cause vaginal bleeding or contraceptive failure.

3. A few women have nausea, vomiting, dizziness and other reactions after taking the medicine, and the reaction peak is mostly 3- 14 hours after taking the medicine. In order to reduce the reaction, it is best to take medicine after meals or before going to bed. In this way, when the drug reacts, the user has fallen asleep, which can greatly reduce the drug reaction.

4, to develop the habit of taking medicine regularly, so it is not easy to forget, to prevent leakage.

If you haven't menstruated for 7 days after taking 22 short-acting contraceptives, you should start taking next month's contraceptives that night. If you don't come to menstruation for 2 months in a row, you should stop taking drugs to check the reasons. At this time, other contraceptive measures should be taken to avoid pregnancy. You can continue to take short-acting contraceptives after menstrual recovery.

6. Oral short-acting contraceptives include oral contraceptive films. 1, No.2 and No.0, the composition and content of which are similar to those of contraceptive pill No. 1, No.2, No.0, using the same method.
