Contraceptives are a remedy for contraceptive failure. They are generally taken within a specified time to play a good role.
However, oral contraceptives are also individualized and have different dosages. However, one critical point is that no contraceptive method can be used over an extended period of time.
When should birth control pills be taken? They are a last resort for unprotected sex and are generally effective within a certain time frame after use.
However, oral contraceptives are also individualized and have varying methods of administration. However, a crucial point to remember is that no contraceptive method can be used indefinitely.
Below, the Ma Family Dictionary will introduce to you what times are effective for various contraceptive pills.
The time to take various contraceptives is as follows: 1. If both partners live in a stable relationship with regular sexual life, they can choose to take short-acting oral contraceptives such as oral contraceptive pills 1 and 2.
Start from the fifth day of menstruation and take one tablet each day for 22 days.
2. When couples live together without a regular schedule, and cannot adhere to daily oral contraceptive use, long-acting oral contraceptives can be selected. For example, the compound 18-methylethinylestradiol can be taken once every fifth day starting from the day of menstruation, with a 20-day interval between doses. Subsequently, one tablet per month is sufficient.
3. Couples living apart due to separation.
When visiting relatives, you may take a condom-type contraceptive medication such as the Condom 1 No.
Take one tablet 8 hours before sex; take another tablet every night until the visit is over, then take one tablet the morning after. Do not use for long term.
4. Women who experience gastrointestinal discomfort from oral contraceptives may opt for the contraceptive injections.
5. If other contraceptive methods fail or the rape victim is found, the post-coital pill can be taken within 24 hours. The dosage should be 50 mg of ethinyl estradiol and it should be taken for five days consecutively.
When is emergency contraception effective? The active ingredient of emergency contraception is progesterone.
The principle of action of drugs is similar to that of the short-acting contraceptives.
For females under 40.
It mainly includes Yuting, Norshun, Baoshengting and Mifesilong tablets.
It is generally recommended to take the first tablet within 72 hours after sexual intercourse, and then take another tablet 12 hours later, with the earlier intake being more effective.
Emergency contraceptive pills, which are also known as over-the-counter (OTC) contraceptives, can be purchased in pharmacies. Some well-known brands include Yutiao and Huiting.
This medication is a steroid, and repeated use can lead to menstrual irregularities and have adverse health effects. When taking it, please pay attention to the following precautions: 1. It should only be used occasionally; generally, no more than one use per month is allowed, and it cannot be used every month.
2. Take one tablet within 72 hours and take another tablet 12 hours later, totaling two tablets.
The earlier you take your medication, the better it will be.
3. If vomiting occurs within 2 hours after taking the medication, a supplemental dose must be taken immediately.
After taking emergency contraceptive pills, you still need to take precautionary measures for contraception if sexual intercourse occurs again, as there is still a possibility of pregnancy.
5. Cardiovascular patients, diabetic patients, breast cancer patients, postpartum women who have been breastfeeding for six months or those who have been confirmed to be pregnant are prohibited from using this medication.
How long after an incident should one take emergency contraceptive medication? The term "contraceptive pill" refers to both oral contraceptives for women and oral contraceptives for men.
In real life, oral contraception is the method of choice for many women. Having used this method for over 20 years, I've come to understand that it has a different impact on different women. Some are willing to use it, while others are not.
Oral contraceptives must be taken at the correct time for them to be effective. Here, Mama Baike will introduce some common post-coal contraceptives for women who need help.
Yu Ting.
The main ingredient is progesterone.
The principle of action of the drug is basically the same as that of short-acting contraceptives.
Applicable to women under the age of 40.
Yuting's mechanism of action is to inhibit ovulation and prevent the implantation of pregnant eggs. In addition, Yuting, this morning-after contraceptive, can also increase the consistency of cervical mucus and the resistance to sperm penetration, thus playing a quick-acting contraceptive role.
However, it is important to remember that Yutai is a rapid-acting, short-acting postcoital contraceptive pill. It should be taken within 72 hours after the sexual encounter and then again 12 hours later.
Mifepristone Tablets.
Low-dose mifepristone has an anti-early pregnancy effect. Post-mortem contraception is enough to take one tablet, which also saves the trouble of taking two tablets. However, you must remember that oral mifepristone must be taken on an empty stomach and can only be eaten 2 hours after a meal.
If you have an adverse reaction of vomiting due to oral administration of mifepristone, you need to take the same dose of mifepristone.
It is important to note that emergency contraception is a 24-hour remedy. After sex, you should immediately take one tablet (the latest within 12 hours), then take another tablet the next morning, and another tablet the night after. Continue taking one tablet daily for three consecutive days, totaling six tablets.
When should the short-acting contraceptive pill be taken? The active ingredients of the short-acting contraceptive pill are progestin and estrogen.
It has the effect of inhibiting ovulation, obstructing the normal growth of endometrial tissue, altering the nature of the vaginal mucus and changing the normal motility of the fallopian tubes.
Applicable to women without underlying diseases or diabetes.
Starting 5 days after the first day of menstruation, take one tablet every night for a continuous period of 22 days. This can be used to prevent pregnancy for one month.
The short-acting oral contraceptives have been widely accepted by modern women for their nearly 100% effectiveness and low incidence of adverse reactions.
However, different women have different adaptability to short-acting oral contraceptives. Some people feel almost no discomfort, and others experience some side effects.
Among them, adverse reactions in the gastrointestinal tract are more common.
Some women may experience early pregnancy reactions such as nausea, vomiting, loss of appetite, dizziness and drowsiness after taking the medicine.
This is because most short-acting oral contraceptives are prepared from synthetic estrogen and progesterone, among which estrogen can stimulate the gastric mucosa and cause discomfort.
This situation mostly occurs in the early stage of medication. After two or three months of continuous medication, it will gradually alleviate or disappear naturally.
So, when is it most effective to take short-acting contraceptives? Mastering the correct medication timing is a good way to avoid early pregnancy reactions.
In general, the early pregnancy reaction caused by taking medicine on an empty stomach is more obvious, while taking medicine after meals can reduce the stimulation of estrogen on gastric mucosa.
In addition, early pregnancy like reactions most occur about 4 hours after taking the drug, so it is best to take short-acting oral contraceptives after dinner or at eight or nine o'clock.
So, it ensures that there is food in the stomach when taking the medication.
Secondly, when the symptoms of early pregnancy manifest, women are likely to be asleep and thus may not feel discomfort.
Long-acting contraceptive pills, when should they be taken? The long-acting contraceptive pill should be taken on the fifth day of menstruation and 20 days later.
Containing human-synthesized progestogen and long-acting estrogen.
The drug enters the body and is stored in adipose tissue, then slowly released to suppress ovulation, and has a long-term contraceptive effect.
Applicable to women who cannot place intrauterine devices, and who are unwilling to use other contraceptive methods.
If efficiency is a concern, long-acting contraceptives are less efficient than short-acting ones.
After taking it, some women will experience increased leucorrhea, menstrual disorders, early pregnancy reactions, and sometimes bleeding, which is difficult to control.
Very few people will experience allergic reactions.
Common long-acting contraceptives include: 1. Compound 16-methylol chlormadinone (referred to as Compound 16-methylol), which is also a type of long-acting contraceptives.
Contains 3 mg of ethynylestradiol, and 10 mg of methytloprogesterone.
2. Compound megestrol injection (7300 injections), the first injection should be injected 1 injection on the 5th and 12th days from the day of menstruation, and then based on the date of the second injection, every 30-31 days, or 1 injection on the 10th to 12th days of menstruation every month.
3. Levonorgestrel and ethinylestradiol tablets: When taking the first dose, take 1 tablet from the 5th and 25th days of menstruation, and then take 1 tablet every month on the same day as the second dose.
