Taking the pre-exposure prophylaxis (PrEP) medication at 22:45, drinking alcohol 15 minutes later, and then having unprotected intercourse with your boyfriend that same night will not reduce the effectiveness of the contraceptive.
However, it is important to take the medication consistently at the same time every day.
If you do so, the chances of pregnancy are close to zero.

When it comes to the interaction between alcohol consumption and emergency contraceptive pills (ECPs), it's important to clarify a few key points regarding their efficacy and safety. Emergency contraceptive pills, such as Plan B (levonorgestrel) or Ella (ulipristal acetate), are designed to prevent pregnancy after unprotected intercourse or contraceptive failure. They work primarily by delaying ovulation, thereby preventing fertilization.

In your case, taking the emergency contraceptive pill and then consuming alcohol shortly afterward is unlikely to significantly affect the efficacy of the medication. Research indicates that moderate alcohol consumption does not impair the effectiveness of ECPs. However, excessive drinking can lead to vomiting, which could potentially affect the absorption of the pill if it occurs shortly after taking it. If vomiting occurs within two hours of taking the pill, it is advisable to consult a healthcare provider, as you may need to take another dose.

Regarding the timing of your actions, taking the emergency contraceptive pill at 22:45 and then drinking alcohol 15 minutes later should not diminish its effectiveness. The key factor is whether the pill was absorbed properly into your system before any potential vomiting could occur. Since you mentioned that you consistently take your regular contraceptive pill on time, this routine can provide additional protection against pregnancy.

As for the risk of pregnancy after having unprotected intercourse following the use of ECPs, it is essential to understand that ECPs are most effective when taken as soon as possible after unprotected sex. They are not 100% effective, and their efficacy decreases the longer you wait to take them after intercourse. If you took the emergency contraceptive pill within the recommended time frame and have been diligent with your regular contraceptive method, the chances of pregnancy are relatively low.

However, if you have concerns about potential pregnancy or experience any unusual symptoms, it is advisable to take a pregnancy test or consult a healthcare professional for further guidance. They can provide personalized advice based on your specific situation and medical history.

In summary, moderate alcohol consumption after taking emergency contraceptive pills is not likely to affect their efficacy. However, it is crucial to be mindful of the timing and potential for vomiting, which could impact absorption. If you have any further questions or concerns about your contraceptive methods or sexual health, do not hesitate to reach out to a healthcare provider for support and information.
