How Does The Morning After Pill Work? (Emergency Contraception)

Unprotected sex can sometimes lead to unplanned pregnancies, but emergency contraception, commonly known as the morning-after pill, can help prevent this. Understanding how the morning-after pill works is crucial for anyone considering using it as a backup option.

The morning-after pill contains the hormone levonorgestrel, which is responsible for its mechanism of action. When taken after unprotected sex, this hormone can prevent ovulation, block fertilization, or prevent a fertilized egg from implanting in the uterus, effectively preventing pregnancy.

It’s important to note that the morning-after pill should not be used as a primary method of birth control. Instead, it should only be used in emergency situations and as directed by healthcare professionals.

Types of Morning-After Pills

The morning-after pill is available in two different types: those containing levonorgestrel and those containing ulipristal acetate.

Levonorgestrel: This type of morning-after pill includes brands such as Plan B One-Step, Take Action, and My Way. Levonorgestrel pills can be purchased over-the-counter without a prescription. These pills should be taken within 72 hours of unprotected sex to be most effective.

Ulipristal Acetate: Ella is the brand name for the morning-after pill containing ulipristal acetate. This type requires a prescription from a healthcare provider. While levonorgestrel pills should be taken within 72 hours, ulipristal acetate pills can be taken within 120 hours of unprotected sex.

Effectiveness of Morning-After Pills

When it comes to preventing pregnancy after unprotected sex, morning-after pills have proven to be effective options. Both levonorgestrel pills and ulipristal acetate pills are commonly used emergency contraceptives. Levonorgestrel pills, such as Plan B One-Step, have a success rate of lowering the chance of pregnancy by 75-89% when taken within 3 days of unprotected sex. On the other hand, ulipristal acetate is considered the most effective morning-after pill available.

While levonorgestrel pills are available over-the-counter without a prescription, ulipristal acetate requires a prescription. It is important to note that the effectiveness of the morning-after pill decreases the longer you wait to take it. Therefore, it is crucial to take the pill as soon as possible after unprotected sex to maximize its effectiveness.

Morning-After Pill Effectiveness
Levonorgestrel (Plan B One-Step) 75-89% effective if taken within 3 days
Ulipristal acetate (ella) Considered the most effective morning-after pill

It is important to remember that the morning-after pill should not be used as a regular form of contraception and does not protect against sexually transmitted infections (STIs). It is designed to be a backup option in case of contraceptive failure or unprotected intercourse. If you have any concerns about the effectiveness of the morning-after pill or need further guidance, consult with a healthcare provider or visit a family planning clinic.

Risks and Side Effects of the Morning-After Pill

The morning-after pill is generally safe to use, but it may have some risks and side effects. It is important to be aware of these potential issues before considering using emergency contraception.

Common Side Effects

The most common side effects of the morning-after pill include:

  • Nausea – Feeling sick to your stomach
  • Vomiting – Emptying the stomach through the mouth
  • Dizziness – Feeling lightheaded or unsteady
  • Fatigue – Feeling tired or weak
  • Headache – Aching pain in the head
  • Breast tenderness – Soreness or discomfort in the breasts
  • Changes in menstrual bleeding – Irregular or abnormal bleeding

These side effects are usually temporary and should resolve on their own within a few days. If any of these symptoms persist or become severe, it is important to consult a healthcare provider.

Possible Risks and Considerations

While the morning-after pill is generally safe for most individuals, there are some factors to consider:

  • The morning-after pill does not protect against sexually transmitted infections. It is important to use barrier methods like condoms to reduce the risk of contracting STIs.
  • Individuals who are overweight or obese may have reduced effectiveness with the morning-after pill.
  • In rare cases, the morning-after pill may fail, and pregnancy may still occur.
  • Using the morning-after pill frequently or as a regular method of contraception is not recommended. It is intended for emergency use only.

It is important to discuss any concerns or questions about the morning-after pill with a healthcare provider to ensure it is the right option for you.

How to Use the Morning-After Pill

Using the morning-after pill correctly is crucial to ensure its effectiveness in preventing pregnancy after unprotected sex. Here are the steps to follow:

  1. Read the instructions: Start by carefully reading the instructions provided with the specific morning-after pill you are using. These instructions will outline the recommended dosage, timing, and any additional considerations.
  2. Take it as soon as possible: Levonorgestrel pills, such as Plan B One-Step, should be taken as soon as possible after unprotected sex, preferably within 72 hours. Ulipristal acetate pills, like ella, should also be taken as soon as possible, but can be taken within 120 hours.
  3. Swallow the pill: Take the pill orally with a glass of water. Do not crush or chew the pill, as this can affect its effectiveness.
  4. Follow up if necessary: If you vomit within two hours after taking the pill, it is recommended to consult a healthcare provider, as you may need to take another dose.
  5. Consider ongoing contraception: The morning-after pill is intended for emergency use only and is not a substitute for regular contraception. It is important to start or continue using a reliable method of birth control to prevent future unintended pregnancies.
  6. Monitor your menstrual cycle: After taking the morning-after pill, it is common for your next period to be earlier or later than usual, and you may experience changes in menstrual flow. If your period is delayed for more than three weeks after taking the pill, it is advisable to take a pregnancy test.

Remember, the morning-after pill is designed for emergency situations and should not be used as a routine method of contraception. If you have any questions or concerns about using the morning-after pill, consult a healthcare professional for guidance.

Emergency Contraception Options: IUDs

If you’re looking for alternative emergency contraception options to the morning-after pill, intrauterine devices (IUDs) are a highly effective choice. There are two types of IUDs commonly used for emergency contraception – the copper IUD and the hormonal IUD.

The Copper IUD

The copper IUD, also known as the copper coil, is a small T-shaped device that is inserted into the uterus by a healthcare professional. It can be used as emergency contraception up to 5 days after unprotected sex, making it a suitable option for those who missed the window for oral emergency contraceptives. The copper IUD works by releasing copper ions into the uterus, which immobilize sperm, prevent fertilization, and create an inhospitable environment for a fertilized egg.

The Hormonal IUD

The hormonal IUD, such as Mirena or Skyla, is another option for emergency contraception. It contains a progestin hormone that thickens cervical mucus, inhibits ovulation, and thins the lining of the uterus. The hormonal IUD can also be used as regular contraception for up to 3-7 years, depending on the type. It requires a healthcare professional for insertion and can be used as emergency contraception within 5 days of unprotected sex.

IUD Type Timing of Use Effectiveness Duration of Contraception
Copper IUD Up to 5 days after unprotected sex Over 99% effective 10-12 years
Hormonal IUD Up to 5 days after unprotected sex Over 99% effective 3-7 years

The copper IUD and hormonal IUD are highly effective and reliable forms of emergency contraception. They provide long-term contraception benefits beyond their use as an emergency option.

Both types of IUDs have their own advantages and considerations, so it’s important to discuss with a healthcare provider which option is best for you based on your individual circumstances and preferences. Keep in mind that IUDs do not protect against sexually transmitted infections, so it’s still important to use barrier methods such as condoms to reduce the risk of STIs.

Emergency Contraception and Menstrual Cycle

When it comes to emergency contraception, it’s important to understand how it can impact your menstrual cycle. Taking the morning-after pill, as well as other forms of emergency contraception, can cause changes in the timing and regularity of your period.

After taking emergency contraception, it is common to experience changes in your next period. Your period may come earlier or later than expected, and it may be heavier or lighter than usual. Some individuals may also experience more spotty bleeding instead of a normal period for that month.

If you have taken emergency contraception and your period is delayed for more than three weeks, it is recommended to take a pregnancy test. While emergency contraception is highly effective in preventing pregnancy, there is still a small chance of becoming pregnant even after taking it.

It is important to note that these changes in your menstrual cycle are temporary and should return to normal in subsequent cycles. If you have concerns about the impact of emergency contraception on your menstrual cycle, it is always best to consult with a healthcare professional for personalized advice.

“Taking emergency contraception can cause changes in your menstrual cycle, but these changes are temporary and should not be cause for alarm. If you have any concerns, it is always best to consult with a healthcare professional.”

Where to Get the Morning-After Pill

When it comes to accessing the morning-after pill, there are several convenient options available. You can find the morning-after pill over-the-counter without a prescription at most drugstores, pharmacies, and superstores. This means you can easily purchase it at places like CVS, Walgreens, or Walmart, without the need for a doctor’s visit or prescription.

Additionally, family planning clinics, health departments, and Planned Parenthood health centers also offer the morning-after pill. These organizations specialize in reproductive health and provide a range of contraceptive options, including emergency contraception. They can provide guidance, support, and information on how to use the morning-after pill effectively.

It’s important to note that the cost of the morning-after pill can vary. Plan B One-Step, one of the most popular brands, typically costs around $40-$50. However, there are also generic options available at a lower cost, offering an affordable alternative.

Conclusion

In conclusion, the morning-after pill serves as an effective emergency contraception option to prevent pregnancy after unprotected sex. By taking it as soon as possible and following the provided instructions, you can increase its effectiveness. However, it is important to note that the morning-after pill is not intended for routine use and should not be relied upon as a primary form of birth control.

While the morning-after pill is generally safe to use, it does come with some risks and side effects. It does not offer protection against sexually transmitted infections, so it is crucial to use additional methods of protection. Common side effects may include nausea, vomiting, dizziness, fatigue, headache, breast tenderness, and changes in menstrual bleeding.

To ensure ongoing pregnancy prevention, it is recommended to explore regular birth control options. The morning-after pill should not be seen as a long-term solution, but rather as a backup plan in case of contraceptive failure or unprotected sex. By being informed about emergency contraception and understanding its limitations, you can make informed choices about your sexual health.
