Switching Birth Control Pills: What to Do with Remaining Pills? - Obstetrics and Gynecology

When switching birth control pills, it's important to understand how to manage the remaining pills from your current pack to ensure effective contraception and minimize any potential side effects. In your case, you have been prescribed a new birth control pill, Alesse, after using Yaz for nearly a month.
Generally, when transitioning from one birth control pill to another, you have a couple of options regarding the remaining pills from your current pack. Here’s a detailed explanation of what you can do:
1. Finish the Current Pack: One common approach is to finish the remaining five pills of Yaz before starting Alesse. This means you would continue taking Yaz until you complete the pack, and then start Alesse on the second day of your next menstrual cycle. This method allows your body to adjust gradually and helps maintain consistent hormone levels, which can be beneficial in preventing any unexpected side effects or breakthrough bleeding.

2. Skip the Remaining Pills: Alternatively, you could choose to stop taking Yaz immediately and start Alesse as directed by your doctor on the second day of your next period. This approach is often recommended if you are experiencing side effects from Yaz or if there are concerns about the effectiveness of the current pill. However, skipping the remaining pills may lead to a higher chance of breakthrough bleeding or hormonal fluctuations, as your body may not have enough time to adjust.

3. Consult Your Doctor: Since you have a specific medical history (such as a chocolate cyst), it’s crucial to follow your doctor’s advice closely. They may have specific reasons for recommending that you start Alesse on the second day of your period, and they can provide personalized guidance based on your health needs.

4. Consideration of Menstrual Cycle: If you decide to finish the Yaz pack, keep in mind that your menstrual cycle may be affected. You might experience a delay in your period or changes in flow when you switch to Alesse. Monitoring your cycle and any side effects during this transition is important.

5. Use Backup Contraception: If you choose to skip the remaining Yaz pills and start Alesse immediately, consider using a backup method of contraception (like condoms) for at least the first seven days of taking Alesse to ensure you are fully protected against pregnancy.

In summary, you can either finish the remaining Yaz pills or stop taking them and start Alesse as directed. The choice depends on your comfort level, any side effects you may be experiencing, and your doctor’s recommendations. Always prioritize communication with your healthcare provider to ensure that your transition between birth control methods is safe and effective.
