how long does the morning after pill last in your system
Introduction
The morning after pill, also known as emergency contraception, is a safe and effective method of preventing pregnancy when taken within a specific time frame after unprotected sex or contraceptive failure. This article aims to provide information on how long the morning after pill lasts in your system, its effectiveness, and what to expect after taking it.
How Does the Morning After Pill Work?
The morning after pill primarily works by delaying or inhibiting ovulation, the process of releasing an egg from the ovary. It may also alter the lining of the uterus, making it less receptive to a fertilized egg and inhibiting implantation. Additionally, it can affect the movement of sperm, reducing the chances of fertilization.
How Long Does the Morning After Pill Last in Your System?
The morning after pill is generally designed to be effective for a short period of time. The most commonly used morning after pill, called Levonorgestrel, is effective for up to 72 hours (3 days) after unprotected sex, while another type containing Ulipristal acetate can be effective for up to 120 hours (5 days) after intercourse.
After ingestion, the active ingredients of the morning after pill are rapidly absorbed into the bloodstream. However, they are metabolized relatively quickly, and their effects diminish over time. Typically, the hormones from the pill are eliminated from your body within a few days to a week.
Effectiveness of the Morning After Pill
The morning after pill is highly effective when taken as directed and within the recommended time frame. Levonorgestrel has a reported effectiveness rate of approximately 85% in reducing the risk of pregnancy, while Ulipristal acetate has an effectiveness rate of around 98%. It is important to note that the sooner the pill is taken after unprotected sex, the more effective it is likely to be.
Side Effects and What to Expect
While side effects may vary from person to person, the morning after pill is generally well-tolerated and safe. Common side effects may include nausea, vomiting, fatigue, breast tenderness, irregular bleeding, or changes in menstrual cycle timing. These side effects typically subside within a few days.
If you vomit within two hours of taking the morning after pill, it is recommended to speak with a healthcare provider, as you may need to take another dose.
Follow-Up after Taking the Morning After Pill
After taking the morning after pill, it is essential to implement a reliable method of contraception to prevent future unintended pregnancies. The morning after pill does not provide ongoing protection against pregnancy, and it should not be used as a routine form of birth control.
It is also important to schedule a follow-up appointment with a healthcare provider within a few weeks after taking the morning after pill. This is to ensure that you are not pregnant and to discuss suitable contraceptive options for ongoing protection.
Conclusion
The morning after pill is a safe and effective method of emergency contraception that can prevent pregnancy if taken within the recommended time frame after unprotected sex. While it does not remain in your system for an extended period, it is crucial to remember that it does not provide ongoing protection against pregnancy. It is always advisable to use a reliable contraceptive method and consult with a healthcare provider for personalized advice on family planning and birth control options.
