MORNING AFTER PILL

Emergency contraception (EC) is a crucial tool for preventing pregnancy after unprotected sex, contraception failure, or missed doses of regular birth control. In this comprehensive guide, we’ll dive deeply into what emergency contraception is, how it works, the different types of pills available, how to use it effectively, and tips on choosing the right EC for your needs. By the end, you’ll have all the information you need to make the best choice in an emergency, ensuring safety, peace of mind, and control over your reproductive health.

How Does Emergency Contraception Work?

Emergency contraception works by delaying ovulation (the process where an egg is released from the ovary, making it available for fertilization) or by preventing implantation of a fertilized egg. By delaying ovulation, EC prevents sperm from meeting an egg, thus preventing pregnancy. It's important to use EC as soon as possible after unprotected intercourse because its effectiveness decreases over time.

There are two primary types of emergency contraception pills (ECPs) available:

  1. Levonorgestrel-Based Pills: Levonorgestrel is a synthetic hormone that mimics natural progesterone in the body. Levonorgestrel-based ECPs are effective when taken within 72 hours (3 days) after unprotected sex. Options in this category include Plan B One-Step, My Way, and Xiromed Emergency Contraceptive.

  2. Mifepristone-Based Pills: Mifepristone is an option that, although different from other common ECs, also works to delay ovulation or preventing implantation. Brands like Mifestad and Mikfepris contain mifepristone (10 mg), which is effective up to 120 hours (5 days) after unprotected sex, giving users a longer time frame compared to levonorgestrel-based EC.

What is Emergency Contraception?

Emergency contraception, commonly known as EC or the “morning-after pill,” is used to prevent pregnancy after sexual intercourse has occurred without effective protection. While it’s highly effective, it’s intended as a backup method rather than a replacement for regular contraceptives. EC is ideal for situations like missed birth control pills, contraception failure (such as a broken condom), or unprotected sex, offering a temporary solution to prevent unintended pregnancy. EC is not an abortifacient—it does not terminate an established pregnancy.

Step-by-Step Guide to Using Emergency Contraception

The effectiveness of emergency contraception depends on understanding the process, selecting the right pill, and following instructions carefully. Here is a complete step-by-step guide on using emergency contraception effectively.

Step 1: Determine If You Need Emergency Contraception

If any of the following situations apply to you, emergency contraception might be necessary:

  • You had unprotected sex and weren’t using any form of birth control.

  • A condom broke, slipped off, or was used incorrectly.

  • You missed multiple birth control pills or used your regular contraceptive method improperly.

  • You are concerned about pregnancy after sexual assault or non-consensual intercourse.


Remember, emergency contraception should only be used as a backup option, not as a regular contraceptive. For ongoing contraception, there are more consistent and effective methods available.

Step 2: Choose the Right Type of Emergency Contraceptive Pill

Choosing the right emergency contraception pill depends on the timing of your situation and personal preferences:

  1. Levonorgestrel-Based Pills (such as Plan B One-Step, My Way, and Xiromed Emergency Contraceptive)

    • Effectiveness Window: Levonorgestrel-based pills are most effective within the first 72 hours after unprotected sex. While they may work for up to 5 days, their effectiveness decreases as time passes.

    • Dosage: Most of these pills contain 1.5 mg of levonorgestrel and are taken as a single-dose pill, making them convenient to use.

    • Over-the-Counter Availability: Levonorgestrel-based pills are generally available over the counter, meaning you don’t need a prescription.

  2. Mifepristone-Based Pills (such as Mifestad and Mikfepris)

    • Effectiveness Window: Mifepristone-based EC can be taken up to 120 hours (5 days) after unprotected sex, offering a broader window of time.

    • Comparison with EllaOne: Though similar in purpose to EllaOne, Mifestad and Mikfepris are accessible without a prescription, which may be more convenient for some.

    • Dosage and Use: Pills typically contain 10 mg of mifepristone and can be used as a single dose.


Selecting the right option will depend on when you’re able to access EC and your preference regarding over-the-counter availability.

Step 3: Take the Pill According to Instructions

Taking emergency contraception correctly is critical for ensuring its effectiveness. Here’s how to take each type:

  • Levonorgestrel Pills: Swallow the single 1.5 mg pill with water. Avoid chewing, crushing, or breaking it as this may affect absorption. Taking the pill sooner rather than later increases its effectiveness.

  • Mifepristone Pills: Like levonorgestrel, take this pill as a single dose and follow any additional instructions provided in the packaging to ensure full effectiveness.

Step 4: Avoid Medications and Substances That May Interfere with EC

Some substances can interfere with the effectiveness of emergency contraception, particularly levonorgestrel-based pills. Be mindful if you are taking or have recently taken the following:

  • Certain Medications: These include antiepileptic drugs, specific antibiotics like rifampicin, antifungals, and herbal supplements such as St. John’s Wort.

  • Alcohol: While not directly interacting with EC, alcohol may impact your ability to follow dosage instructions or timing accurately.


If you’re on any medication, consider consulting a healthcare provider to ensure your emergency contraception will work effectively.

Step 5: Watch for Possible Side Effects

As with any medication, emergency contraception can come with side effects. While these vary by individual, the most common side effects include:

  • Nausea or Vomiting: Some people feel mildly nauseous. If you vomit within two hours of taking the pill, you may need to take another dose, as the initial pill might not have been fully absorbed.

  • Headaches: Some individuals experience mild to moderate headaches, which can usually be managed with over-the-counter pain relief.

  • Menstrual Changes: Your next period might be earlier, later, or heavier than usual. This is normal and not a cause for concern.

  • Dizziness and Fatigue: Temporary symptoms that typically resolve on their own within a day or two.


Most side effects are short-lived and should pass without medical intervention. However, if they persist, reach out to a healthcare provider.

Step 6: Track Your Menstrual Cycle

Emergency contraception can influence your menstrual cycle, causing a temporary delay or change in flow. Here’s what to watch for:

  • Expect a Period Change: Your period may come a few days earlier or later. This variation is usually temporary.

  • Consider Taking a Pregnancy Test: If your period is delayed by more than a week, take a home pregnancy test to confirm EC effectiveness.


Tracking your cycle can provide additional peace of mind and help you know when to expect your next period.

Step 7: Consider Your Future Contraceptive Needs

Emergency contraception is effective but not designed for routine use. If you’ve found yourself using EC frequently, consider exploring long-term contraception options. Common methods include:

  • Birth Control Pills: Daily hormone pills that are over 90% effective when taken consistently.

  • Intrauterine Devices (IUDs): These provide protection from pregnancy for 3-10 years, depending on the type.

  • Implants and Injections: Both methods offer sustained protection from pregnancy and eliminate the need for daily or weekly reminders.


A healthcare provider can help you select a method that aligns with your lifestyle and preferences, offering you more consistent protection and peace of mind.

Understanding Each EC Product: Brands Available

Each emergency contraceptive option has unique features that might make it a better fit for certain people. Here’s a rundown of popular brands available:

  1. Plan B One-Step (Levonorgestrel 1.5 mg): This is one of the most recognized brands of EC, available over the counter and effective when taken within 72 hours. It is often slightly more expensive than other options but is known for its reliability and widespread availability.

  2. My Way (Levonorgestrel 1.5 mg): A generic version of Plan B, My Way offers similar effectiveness at a lower price point, making it a great choice for those seeking affordability without compromising efficacy.

  3. Xiromed Emergency Contraceptive (Levonorgestrel 1.5 mg): Comparable to Plan B and My Way, Xiromed is a convenient choice available at most pharmacies and over-the-counter locations, providing flexibility for those who need a reliable EC option.

  4. Mifestad (Mifepristone 10 mg): Mifestad can be taken up to 5 days after unprotected sex, giving users an extended time frame. Unlike some prescription-only alternatives, Mifestad is more accessible.

  5. Mikfepris (Mifepristone 10 mg): Like Mifestad, Mikfepris provides the convenience of a 5-day window without a prescription, offering more freedom in situations where immediate access to EC might not be possible.

Final Thoughts on Emergency Contraception

Emergency contraception is an important option for anyone who may encounter unprotected sex or contraception failure. With the knowledge of how to use EC effectively and the variety of options available, you can take charge of your reproductive health with confidence.

Remember, while emergency contraception is effective in the short term, it’s always best to have a reliable, long-term contraceptive plan in place for ongoing protection. Always consult with a healthcare professional if you have concerns or questions about your contraceptive needs, as they can provide personalized recommendations tailored to your lifestyle and health history.

Emergency contraception empowers you to make informed choices about your reproductive health and provides peace of mind, ensuring you have control over your body and future.
