Contraceptive Pills and Menstrual Delay Medications - Obstetrics and Gynecology

I would like to inquire about the usage of oral contraceptives and whether it is safe to take medication for delaying menstruation while on birth control pills?


Hello, doctor.
I am currently taking a medication to delay my period (Lemiphen tablets) and I have communicated with the pharmacist that I will be taking it until June 10th (today is June 3rd, the seventh day).
After finishing the period delay medication, I plan to start taking the combined oral contraceptive pill (Yaz 28) on the first day of my period this month (the pharmacist mentioned that I should start on the first day).
I also found information online stating that I can start the next pack immediately after finishing one pack.
However, if my period starts on June 13th, I will be traveling on July 15th and may encounter my period again, so I would need to take the period delay medication for a few more days.
During this travel period, if I engage in sexual activity, should I take protective measures? If I am taking the contraceptive pill, how should I take the period delay medication and then continue with the contraceptive pill? Is it acceptable to start the contraceptive pill on the first day of my period? Does the contraceptive pill provide contraceptive protection after taking it for 7 days? Please help clarify these concerns, thank you!

Wishing you good health!

More Info


Understanding contraceptive pills and medications for menstrual delay can be quite complex, especially when trying to coordinate their use effectively. Let's break down your questions and concerns regarding the use of these medications.


Menstrual Delay Medications
You mentioned that you are currently taking a medication called "利美信錠" (likely referring to a form of hormonal medication used to delay menstruation). This type of medication is often prescribed to postpone your period for various reasons, such as travel or special events. The typical recommendation is to start taking this medication a few days before your expected period and continue until you wish to delay your menstruation, as advised by your healthcare provider.


Contraceptive Pills
You also mentioned that you plan to start taking "悦姿28天" (a combined oral contraceptive pill) on the first day of your period. This is a common practice, and many healthcare providers recommend starting the pill on the first day of menstruation for immediate contraceptive protection. However, it is essential to understand that while some women may experience contraceptive effects sooner, it is generally advised to use an additional form of contraception (like condoms) for the first seven days of taking the pill to ensure maximum effectiveness.


Timing and Coordination
1. Starting the Contraceptive Pill: If you take the menstrual delay medication until June 10 and your period starts on June 11, you can begin taking the contraceptive pill on that same day. This is a standard approach, and it allows you to transition smoothly from one medication to the other.

2. Continuing the Contraceptive Pill: If you are concerned about your period arriving on June 13 and you have plans on July 15, you can continue taking the contraceptive pill as directed. If you wish to delay your period again, you can consult your healthcare provider about taking another course of menstrual delay medication after finishing your contraceptive pill pack.

3. Protection During Intercourse: If you have been taking the contraceptive pill for at least seven days, you should be protected against pregnancy. However, if you have just started the pill and have not yet completed the seven-day window, it is advisable to use additional protection (like condoms) during this time, especially if you are engaging in sexual intercourse.


Additional Considerations
- Consult Your Healthcare Provider: It is crucial to communicate with your healthcare provider about your specific situation, especially if you have any underlying health conditions or if you are taking other medications that might interact with hormonal contraceptives.

- Potential Side Effects: Be aware of potential side effects from both the menstrual delay medication and the contraceptive pill, such as nausea, headaches, or changes in mood. If you experience severe side effects, consult your healthcare provider.

- Regular Monitoring: If you are using these medications regularly, it may be beneficial to have regular check-ups with your healthcare provider to monitor your health and ensure that the medications are working effectively for you.

In summary, you can start the contraceptive pill on the first day of your period after taking the menstrual delay medication. Ensure to use additional protection if you are within the first week of starting the pill. Always consult your healthcare provider for personalized advice tailored to your health needs.
