Many patients and friends are skeptical about doctors applying contraceptive pills to treat diseases, especially girls who have not yet had sex: will long-term use of contraceptive pills harm the body? The reason for this may be related to the early long-acting contraceptive pills, emergency contraceptive pills have more side effects, and patients and friends can not correctly distinguish between the types of contraceptive pills, so the contraceptive pills have misunderstandings and concerns. No hurry, we will go through the following questions to recognize the “pill”. What are the types of birth control pills? Oral contraceptives are mainly: short-acting contraceptives, emergency contraceptives, long-acting contraceptives 1, short-acting contraceptives: that is, long-term contraceptives, the main components of progesterone and estrogen, Mindin even, Momofuron, Tejule, Yosmin, Daying-35 and so on belong to the short-acting contraceptives. This type of contraceptive pill is a long-term short-acting contraceptive pill, that is, a piece of top day, must be taken consistently, because it is safe and effective, applicable to all normal healthy women except breastfeeding. It works by reducing the secretion of gonadotropins to inhibit ovulation and thus contraception. Its contraceptive efficiency is almost 100 percent. 2.Emergency contraceptive pill: the main ingredient is progesterone, because of its high dosage, the side effects are relatively large. Generally speaking, the emergency contraceptive pill should not be used more than 3 times a year. Yuk-Ting, Danmei, Nu-Shuang, Pao-Shi-Ting and Mifepristone tablets are emergency contraceptive pills. The progesterone content of one morning-after pill is equivalent to the dose of six regular birth control pills, which will raise the progesterone level in the body first to more than six times the normal level at once, and then drop down sharply to a level far below normal. Progesterone down to far below normal levels, the endometrium can not get the support of progesterone will fall off bleeding, so as to achieve the contraceptive effect. 3.Long-acting contraceptive pills: Containing synthetic progesterone and long-acting estrogen, they play a long-acting contraceptive role and are suitable for women who cannot place an intrauterine device and do not want to use other contraceptive methods. You only need to eat 1 to 2 times a month, the principle of action is similar to the short-acting contraceptive pill, but the hormone dose is much larger than the short-acting contraceptive pill. Second, the choice of contraceptive pills? 1, short-acting contraceptive pills: conventional contraceptive pills, but also doctors often prescribe contraceptive pills to patients. This kind of contraceptive pill dose is low, a top day, can be taken for a long time, safe and effective, with little side effects, in the treatment of many gynecological diseases is also useful, a multi-purpose drug, to the majority of female friends to bring the gospel. 2, long-acting contraceptive pills: although it is convenient to take, but its dose is large, a large number of hormone stimulation may appear leucorrhoea, breast swelling and pain, menstrual irregularities and other side effects, the clinical use of less, should not be used without authorization, you need to consult a clinician. 3, emergency contraceptive pills: we are relatively familiar with, can be defined as a spare tire, if the coitus did not take contraceptive measures or condom breakage, slippage, and failure of extracorporeal spermatozoa, women were accidentally injured and other situations can use emergency contraceptive pills, that is, do not use as a last resort, don’t use. Third, the use of contraceptive pills? 1, short-acting contraceptive pills: generally from the fifth day of menstruation to take, 1 tablet per day, for 21 days, can not be interrupted, if the occasional leakage of service should be replaced within 24 hours to take a tablet. After stopping the pill, 2 to 5 days after menstruation, and then on the 5th day of menstruation to take the next cycle of the drug, the same method as above. If it is for contraceptive purpose, it can be taken for a long time. If it is for the treatment of dysmenorrhea, endometriosis, etc., the cycle of medication should be adjusted under the guidance of the doctor. 2, long-term contraceptive pills: mainly rely on ethinyl estradiol stored in fatty tissues and gradually released to play a long-lasting effect, clinical use is less. Take 1 pill on the 5th day of menstruation, and then take 1 pill every 28-30 days. 3.Emergency contraceptive pills: take emergency contraceptive pills within 72 hours after intercourse, and then take one tablet every 12 hours, the total number of 2 tablets, the sooner you take the better. Fourth, the side effects of birth control pills? 1, first of all, you have to carry out the emergency contraceptive pill, this drug is the most clinicians do not recommend. Because it is too large a dose, many side effects, often lead to menstrual disorders, vaginal bleeding, early or delayed menstruation, or even amenorrhea, patients may have nausea, vomiting, headache, dizziness, fatigue, breast swelling and other discomforts. And patients are most likely to take such contraceptives, and then menstrual disorders to the hospital, this type of drug can only be used as a non-willful pregnancy and did not do a good job of contraception remedies, can not be used as a regular contraceptive drugs. 1, long-acting contraceptives: after taking the leukorrhea, nausea, vomiting and other early pregnancy reactions, there are also patients with menstrual disorders. This type of contraceptive pill is less clinically used. 2, short-acting contraceptives: compared to the most assured drug, safe and effective, relatively small side effects, and can be used to adjust the menstrual cycle, treatment of dysmenorrhea, improve menstrual cramps, etc., the highest frequency of clinical use. Through the above explanation, I believe we have a basic understanding of the contraceptive pill. As long as they are taken correctly, the benefits outweigh the disadvantages for most patients. The next article we will focus on the short-acting contraceptive pill, perhaps you will have a different understanding of the pill Oh.
