Does taking emergency contraceptive pills after sex work?

When there is no protection during sexual life, or there is protection but an accident occurs, but you do not want to get pregnant, you can take emergency contraceptive pills. If you take the medicine at the right time and as required, the contraceptive effect is generally very good. But this emergency contraceptive pill is only an emergency remedy and should not be taken frequently. So, what should you pay attention to when taking emergency contraceptive pills to make them work better?

Emergency contraceptive pills refer to contraceptive methods used to prevent pregnancy within a period of time after unprotected sex or contraceptive failure. Drug contraception is the most commonly used contraceptive method.

Women can consider taking emergency contraceptive drugs if they suffer accidental injuries or have unprotected sex for other reasons, or if contraception fails, such as condom breakage, slippage, or incorrect calculation of the safe period. The drugs are effective within 72 hours after intercourse. If they have sex again while taking the drugs, the time must be recalculated.

After healthy women of childbearing age have ruled out pregnancy, they should use the drug within 72-120 hours after sexual intercourse. The earlier it is taken, the better the effect. The failure rate is often higher if it is taken more than 72 hours. Therefore, emergency contraceptive pills are also called 72-hour emergency contraceptive pills.

A commonly used type of emergency contraceptive is a single progestin, the ingredient of which is levonorgestrel, which is an over-the-counter drug. This type of 72-hour emergency contraceptive pill is represented by Xinsnuo Pills and Yuting. The earlier emergency contraceptive pills are taken, the more effective they are in preventing pregnancy. No need to fast before or after taking it.

Another type of emergency contraceptive pill is antiprogestin. The most commonly used one is Houdingnuo. In addition, there are Simian tablets, Biyun capsules, Huadian tablets, etc. The active ingredient is mifepristone, and they are all prescription drugs.

Only one tablet of this medicine needs to be taken, and fasting is required for 2 hours before and after taking the medicine. The chance of pregnancy after taking the medicine can be reduced to 1.4%. There are few side effects, but the side effects are large. Some people experience changes in their menstrual periods. If vomiting occurs within two hours after taking the medicine, if the medicine is vomited out, you need to take the same dose of medicine once.

The sooner you take emergency contraceptive pills, the better, and no later than 72 hours, otherwise the emergency contraceptive pills will not work. Moreover, the side effects of emergency contraceptive pills are relatively large. If taken too frequently, it may cause women to experience menstrual disorders, premature ovarian failure and other symptoms, so you must pay attention.
