The morning after pill, also known as emergency contraception, is a form of birth control that can be used to prevent pregnancy after unprotected sex or when a primary form of birth control fails. With several options available, it's essential to understand how each works, their effectiveness, and potential side effects.

Emergency contraception has been a vital part of reproductive health for decades, providing a second chance for individuals to prevent unintended pregnancy. However, with various products on the market, it can be overwhelming to determine which one is best suited for your needs. This guide aims to provide a comprehensive overview of the morning after pill, helping you make an informed decision about your reproductive health.
Types of Morning After Pills
There are several types of morning after pills available, each with its own unique characteristics and effectiveness. The most common options include:
- Plan B One-Step (levonorgestrel): This is one of the most well-known emergency contraceptive pills, available over-the-counter (OTC) for individuals 17 years and older.
- Next Choice (levonorgestrel): Similar to Plan B, Next Choice is another levonorgestrel-based option that can be purchased OTC for those 17 and older.
- Ella (ulipristal acetate): This pill is available by prescription only and can be effective up to 120 hours after unprotected sex.
How Morning After Pills Work
Morning after pills work by preventing or delaying ovulation, fertilization, or implantation of a fertilized egg. The exact mechanism depends on the type of pill:
Levonorgestrel-based pills (Plan B, Next Choice) primarily work by:
- Preventing ovulation: By releasing hormones that stop the release of an egg from the ovary.
- Thickening cervical mucus: Making it more difficult for sperm to reach the egg.
Ulipristal acetate-based pills (Ella) work by:
- Delaying ovulation: Ulipristal acetate can delay ovulation for a longer period, up to 120 hours.
- Preventing implantation: If ovulation has already occurred, ulipristal acetate may prevent a fertilized egg from implanting in the uterus.
Effectiveness of Morning After Pills
The effectiveness of morning after pills varies depending on the type and how quickly they are taken after unprotected sex:
| Type of Pill | Effectiveness if Taken Within 24 Hours | Effectiveness if Taken Within 72 Hours | Effectiveness if Taken Within 120 Hours |
|---|---|---|---|
| Levonorgestrel-based (Plan B, Next Choice) | 95% | 89% | Less effective |
