Tag: Yuzpe method

While some combined birth control pills *can* be used for emergency contraception (EC), a 2014 study by the AAFP shows the Yuzpe method to be significantly less effective than dedicated EC pills. This practice is generally not recommended due to lower efficacy and higher side effects compared to modern options.

In the United States, 14% of women aged 15–49 use oral contraceptive pills, making it one of the most common forms of birth control [1.6.1]. This prevalence leads to questions about their use and misuse, including: **Can I take 5 birth control pills at once?** While not typically life-threatening, doing so is unsafe and carries significant risks.

Studies show that the Yuzpe regimen of emergency contraception reduces the risk of pregnancy by about 74% [1.5.1]. A common question is, 'Why do I get so sleepy after doing the Yuzpe method?' The answer lies in the high dose of hormones.

Following emergency hormonal contraception, studies show that many women experience an earlier onset of their next menses, with the Yuzpe method in particular often leading to menstrual cycle alterations due to its high hormone content. Understanding the expected timeline for bleeding after the Yuzpe method is crucial for managing expectations and monitoring your body's response.

Studies have shown that fatigue is a possible side effect of the Yuzpe method, with one older World Health Organization (WHO) trial reporting tiredness in nearly 30% of women using the regimen. This feeling of sleepiness is primarily due to the high dose of hormones disrupting the body's natural cycle.

The modern Plan B One-Step is a single, high-dose pill, and the question of how many pills equal a Plan B? is often based on outdated information or confusion surrounding the use of regular birth control for emergency contraception. While the single-pill regimen is the standard today, understanding the history and alternatives clarifies why relying on other methods can be less effective and cause more side effects.
