what is Emergency contraception
Emergency contraception, also known as the morning-after pill, is a type of contraception that can be used to prevent pregnancy after unprotected sex or when other forms of contraception have failed. It is meant to be used as a backup method of contraception and is not intended to be used as a primary method. Emergency contraception works by either delaying ovulation (the release of an egg from the ovary), preventing fertilization of the egg by sperm, or preventing implantation of a fertilized egg in the uterus. It is most effective when taken as soon as possible after unprotected sex, ideally within 72 hours, but can be taken up to 120 hours (5 days) after.
Types of emergency contraception
There are different types of emergency contraception available, including pills that contain the hormones levonorgestrel or ulipristal acetate, or a copper intrauterine device (IUD). These options should be discussed with a healthcare provider to determine the most appropriate choice based on individual circumstances.
It is important to note that emergency contraception is not a substitute for regular contraception and should only be used in emergency situations. It does not protect against sexually transmitted infections (STIs) and does not work if a woman is already pregnant. Regular contraception, such as birth control pills, condoms, or an IUD, should be used to prevent unintended pregnancy
Effectiveness of emergency contraception
The most effective form of emergency contraception is the copper intrauterine device (IUD), which can be inserted up to five days after unprotected sex. It is more than 99% effective at preventing pregnancy.
It is important to note that emergency contraception is not 100% effective and may not prevent all pregnancies. It is also important to use regular contraception to prevent unintended pregnancy and to protect against sexually transmitted infections (STIs). Emergency contraception should only be used in emergency situations and is not intended to be used as a regular form of contraception.
Choosing the Right emergency contraception
Choosing the right emergency contraception depends on various factors, including the type of emergency contraception available, how soon after unprotected sex it can be taken, and individual medical history and preferences.
There are three types of emergency contraception available: levonorgestrel pills, ulipristal acetate pills, and the copper intrauterine device (IUD).
- Levonorgestrel pills are the most commonly used emergency contraception and are available over-the-counter without a prescription in many countries. They are effective up to 72 hours after unprotected sex and are generally well-tolerated. Levonorgestrel pills may not be as effective for women who are overweight or obese.
- Ulipristal acetate pills are a newer form of emergency contraception that are available by prescription only. They are effective up to 120 hours after unprotected sex and may be more effective than levonorgestrel pills, particularly for women who are overweight or obese. Ulipristal acetate pills may not be appropriate for women with liver disease or severe asthma.
- The copper IUD is the most effective form of emergency contraception and can be inserted up to five days after unprotected sex. It can also be used as long-term contraception if desired. However, it requires a healthcare provider to insert it and may not be suitable for women who cannot use a copper IUD for regular contraception.
Ultimately, the choice of emergency contraception should be discussed with a healthcare provider, who can recommend the most appropriate option based on individual circumstances and medical history.
