Accidentally Taking Extra Birth Control Pills: What to Do? - Obstetrics and Gynecology

I took an extra birth control pill today?


Hello, doctor.
I am currently taking the brand "Aiji" for 21 days.
I would like to ask if starting a day early (originally supposed to start on 11/8 but accidentally started on 11/7) and accidentally taking two pills in one day will affect its efficacy? Should I continue taking one pill a day until I finish?

Miss Zhu, 30~39 year old female. Ask Date: 2023/11/25

Hello, just continue taking the medication as prescribed.
Wishing you good health.

More Info


When it comes to birth control pills, particularly combination pills like the one you mentioned (21-day regimen), it's important to understand how to manage any accidental changes in your dosing schedule.
If you accidentally start taking your birth control pill one day earlier than scheduled, it generally should not have a significant impact on the effectiveness of the pill. Birth control pills are designed to maintain hormone levels in your body, and taking an extra pill a day early is unlikely to disrupt this balance. You can continue taking the pills as directed, one per day, until you finish the pack.
However, if you accidentally take two pills in one day, it’s important to note that while this may not pose a serious health risk, it could lead to some side effects. Common side effects of taking extra birth control pills include nausea, vomiting, or breakthrough bleeding. If you experience any severe side effects or have concerns, it’s always best to consult with your healthcare provider.

In terms of effectiveness, if you take two pills in one day, you should still be protected against pregnancy as long as you continue to take the remaining pills correctly. The key is to maintain a consistent schedule moving forward. After finishing the pack, you should start your next pack on time, regardless of the minor adjustments made.

It's also worth mentioning that if you miss a pill (which is defined as not taking it within 24 hours of your scheduled time), the effectiveness of the pill can be compromised. In such cases, the general advice is to take the missed pill as soon as you remember, even if it means taking two pills in one day. If you miss two or more pills, the guidance may vary depending on how far along you are in your cycle, so it’s crucial to refer to the specific instructions that come with your pill pack or consult your healthcare provider.

In summary, if you accidentally start your birth control pill a day early or take two pills in one day, you should continue taking the remaining pills as scheduled. Monitor for any side effects, and if you have any concerns about your birth control effectiveness or experience unusual symptoms, reach out to your healthcare provider for personalized advice. Remember, maintaining open communication with your healthcare provider about any concerns or questions regarding your birth control method is essential for your reproductive health.
