Introduction
Plan B, also known as emergency contraception or the morning-after pill, is a form of birth control that can be taken up to five days after unprotected sex. It is designed to prevent pregnancy by delaying ovulation, but it does not protect against sexually transmitted infections (STIs). So, if you have had unprotected sex, it is important to understand how long after sex you can take Plan B to ensure it is effective.
Exploring the Time Frame of Plan B’s Effectiveness After Sex
When considering when to take Plan B, it is important to understand the window of time in which it is effective after having unprotected sex. The sooner you take Plan B, the more likely it is to work.
How Soon After Sex Can You Take Plan B?
The effectiveness of Plan B decreases the longer you wait to take it. According to the American College of Obstetricians and Gynecologists, Plan B is most effective when taken within 24 hours of unprotected sex, with efficacy ranging from 75% to 89%. For best results, it is recommended to take Plan B as soon as possible after unprotected sex.
Understanding the Window of Time to Take Plan B After Sex
Although Plan B is most effective when taken within 24 hours, it can still be taken up to five days after unprotected sex. Studies have shown that Plan B is still effective up to 72 hours after unprotected sex, with efficacy decreasing over time. When taken between 72 and 120 hours (five days) after unprotected intercourse, Plan B’s efficacy drops to 58%. So, while it may still be effective, the chances of it working decrease significantly.
How Long Is Too Long to Wait Before Taking Plan B?
Waiting too long to take Plan B can have serious consequences. There is a chance of an unintended pregnancy if Plan B is taken after five days, so it is important to understand the risks associated with delaying taking the medication. Additionally, it is important to note that Plan B does not protect against STIs, so it is important to get tested for STIs if you have had unprotected sex.
Effects of Delay in Taking Plan B
A study conducted by the World Health Organization found that the risk of unintended pregnancy increases the longer you wait to take Plan B. The study showed that when Plan B was taken within 24 hours of unprotected intercourse, the risk of unintended pregnancy was reduced by 85%. However, when Plan B was taken between 72 and 120 hours (five days) after unprotected intercourse, the risk of unintended pregnancy increased to 58%.
