When should contraceptive pills be taken for them to be effective?

Emergency contraception is a very common contraceptive method at present. Many people use birth control pills to prevent pregnancy, but when is the best time to take emergency contraception? What should I pay attention to when taking emergency contraception? However, few people know about these issues, so it is necessary for everyone to understand the professional knowledge in these areas.

When is the right time to take emergency contraception?

1. Contraceptive pills need to be taken in two doses. The first dose is usually taken within 72 hours after intercourse, and the second dose is taken 12 hours later. The sooner you take it, the better the actual effect. The main ingredient of the contraceptive pill is luteal copper. The working principle of this drug is basically the same as that of short-term contraceptive pills and is suitable for women under 40 years old.

2. Short-term contraceptives should be taken starting from the 5th day after the menarche, 1 tablet every night, and then continue to take it for 22 days, which can provide contraceptive measures for 1 month. The main function of short-term contraceptives is to inhibit ovulation and prevent normal uterine wall development. Suitable for women without underlying diseases or diabetes.

3. Long-term contraceptives are generally taken on the fifth day after menarche, with one tablet taken 20 days later to achieve the actual effect of effective contraceptive measures. Long-term contraceptives mainly contain progesterone and high-efficiency estrogen, which can inhibit ovulation and are suitable for women who cannot place an IUD and do not want to use other contraceptive measures.

The actual effect of taking birth control pills depends on the type of contraceptive measures and the woman's own physical condition. If you don't know how to take birth control pills, you can see instructions on emergency contraception. When taking emergency contraception, you should also check whether the medicine is expired. When taking emergency contraception for a long time, you need to pay attention to the following aspects:

1. Symptoms of nausea and vomiting may occur after taking emergency contraception, but usually do not exceed 24 hours. So if you feel nauseous, don't panic, it's normal, just take a rest.

2. Taking medicines and food at the same time can reduce the possibility of nausea and vomiting. But please note that if you vomit within 1 hour after taking the oral contraceptive pill, you should take another pill as soon as possible to avoid accidental pregnancy.

3. Some women may experience a little bleeding after taking the medicine. This generally does not need to be treated, but the contraceptive users need to be aware of this situation to avoid being at a loss when bleeding is discovered.

4. Most women have regular menstrual periods, but some women have early or delayed menstrual periods. If your period is delayed for a week after taking the pill, you should take an early pregnancy test to see if the emergency contraceptive method is unsuccessful.

5. Taking birth control pills can cause changes in the ovulation period and affect the menstrual cycle. Therefore, women should use safe contraceptive measures as much as possible, rather than taking risks by using birth control pills or unreasonable contraceptive measures such as the safe period of menstruation and ejaculation outside the body, because this method may cause infertility.

6. Taking emergency contraception may also cause breast pain, headache, dizziness, fatigue, etc., but these symptoms are generally mild and last no more than 24 hours. Breast pain and severe headaches can be treated with aspirin or other pain relievers.
