The Plan B pill, also known as the morning-after pill, is a form of emergency contraception designed to prevent pregnancy after unprotected sex or when other forms of contraception have failed. It is a highly effective and safe method of preventing pregnancy, but it is not intended for regular use as a contraceptive method.
How Does the Plan B Pill Work?
The Plan B pill works by delaying or preventing ovulation, which is the release of an egg from the ovary. It contains a high dose of a hormone called levonorgestrel, which is a form of progestin. This hormone helps to prevent the egg from being released, thereby preventing fertilization. If ovulation has already occurred, the Plan B pill can also help to prevent the fertilized egg from implanting in the uterus.
When Should the Plan B Pill Be Taken?
The Plan B pill should be taken as soon as possible after unprotected sex or when other forms of contraception have failed. The sooner it is taken, the more effective it is in preventing pregnancy. It can be taken up to 72 hours after unprotected sex, but it is most effective when taken within the first 24 hours.
Types of Emergency Contraception
There are several types of emergency contraception available, including:
- Plan B One-Step: This is a single dose of levonorgestrel that is taken as soon as possible after unprotected sex.
- Plan B: This is a two-dose regimen of levonorgestrel that is taken 12 hours apart.
- Ella: This is a single dose of ulipristal acetate that is taken as soon as possible after unprotected sex.
- Copper IUD: This is a type of intrauterine device that can be inserted up to 5 days after unprotected sex to prevent pregnancy.
Effectiveness of the Plan B Pill
The Plan B pill is highly effective in preventing pregnancy when taken as directed. According to the manufacturer, it can reduce the risk of pregnancy by up to 89% when taken within the first 72 hours after unprotected sex. However, it is not 100% effective, and there is still a small chance of pregnancy.
Side Effects of the Plan B Pill
The Plan B pill can cause some side effects, including:
- Nausea and vomiting

These side effects are usually mild and temporary, and they should resolve on their own within a few days.
