Emergency contraceptive pill
An emergency contraceptive pill, also known as a morning-after pill, is a type of contraception used to prevent pregnancy after unprotected sex or contraceptive failure. Plan B is one of the most well-known emergency contraceptive pills. It contains a high dose of a hormone called levonorgestrel, which is similar to the progestin found in birth control pills.
Plan B works by preventing or delaying ovulation, which is the release of an egg from the ovary. It can also prevent fertilization of an egg by sperm or the implantation of a fertilized egg in the uterus. Plan B is most effective when taken within 72 hours (3 days) of unprotected sex, but it can still be effective if taken up to 120 hours (5 days) after sex.
Plan B is available over-the-counter in most countries, meaning you can buy it without a prescription. It is important to read and follow the instructions on the package carefully before taking Plan B.
Plan B is generally safe and well-tolerated, but it can cause side effects, such as nausea, vomiting, headache, fatigue, and irregular bleeding. These side effects usually go away within a few days.
If you are considering using Plan B, it is important to talk to your doctor or pharmacist to make sure it is right for you.
Prevents pregnancy
Plan B works by preventing pregnancy in several ways. It can:
- Prevent ovulation: Plan B contains a high dose of the hormone levonorgestrel, which can prevent or delay ovulation, the release of an egg from the ovary.
- Prevent fertilization: If ovulation has already occurred, Plan B can prevent fertilization of the egg by sperm. It does this by thickening the mucus in the cervix, making it more difficult for sperm to reach the egg.
- Prevent implantation: If fertilization has already occurred, Plan B can prevent the fertilized egg from implanting in the lining of the uterus. This is the process by which a pregnancy begins.
Plan B is most effective when taken within 72 hours (3 days) of unprotected sex, but it can still be effective if taken up to 120 hours (5 days) after sex. However, the sooner you take Plan B after unprotected sex, the more effective it will be.
Plan B is not 100% effective, and it does not protect against sexually transmitted infections (STIs). If you are concerned about STIs, you should use a condom during sex.
