Contraceptive pill issues


Hello, doctor.
I have encountered a few questions recently and hope to get some answers.
Thank you, doctor!
1.
Do oral contraceptives interact with psychiatric medications (such as Yongkangxu, Eistan, and Paxil)?
2.
I experienced bleeding three days after taking the emergency contraceptive pill.
Is this my period?
3.
Can I use the usual methods to delay my period during the withdrawal bleeding phase after stopping the oral contraceptive?
Thank you again, doctor!

Dr. Huang Yiwen reply Obstetrics and Gynecology


Hello, Miss Ni: 1.
It is generally more appropriate to obtain emergency contraceptive pills from a psychiatrist, especially if one needs to take them in the morning and the other at noon or in the evening.
2.
It is quite common to experience light bleeding within a few days after taking emergency contraceptive pills, so there is no need to worry too much.
If the bleeding is heavier, it can be considered as a menstrual period.
3.
If the timing of the bleeding is still quite far from when your next period is due, you can use the usual methods to delay your period.

Dear Patient,
Thank you for your questions regarding birth control and menstrual concerns. These topics are essential for understanding reproductive health, and I’m happy to provide clarity on each of your inquiries.

1. Interactions Between Birth Control Pills and Psychiatric Medications:
It is crucial to understand that certain psychiatric medications can interact with hormonal contraceptives. For example, some antidepressants, particularly those that affect serotonin levels, may not have a significant impact on the efficacy of birth control pills. However, medications like certain antiepileptics and some herbal supplements (like St. John's Wort) can reduce the effectiveness of hormonal contraceptives. The medications you mentioned—Yongkangxu (likely a misspelling or a brand name), Esetan, and Paxil (百憂解)—should be discussed with your healthcare provider. They can assess your specific situation and determine if any adjustments to your birth control method are necessary.

2. Bleeding After Taking Emergency Contraceptive Pills:
Experiencing bleeding three days after taking emergency contraception (often referred to as the "morning-after pill") is not uncommon. This bleeding can occur due to the hormonal changes induced by the emergency contraceptive. It may not necessarily be your regular menstrual period but could be a side effect of the medication. Typically, your next menstrual cycle may be affected, either coming earlier, later, or being heavier or lighter than usual. If you have concerns about the nature of the bleeding or if it continues, it’s advisable to consult your healthcare provider.

3. Delaying Menstrual Bleeding After Stopping Birth Control Pills:
When you stop taking birth control pills, your body may take some time to adjust, and you might experience withdrawal bleeding. If you wish to delay your period after stopping the pill, it is possible to use hormonal methods to do so. For instance, some women choose to start a new pack of birth control pills immediately after finishing the previous one without taking the placebo pills, effectively skipping the withdrawal bleed. However, this should be done under the guidance of a healthcare provider to ensure it is safe and appropriate for your health situation.

In addition to these answers, it’s essential to maintain regular communication with your healthcare provider regarding any medications you are taking, including birth control and psychiatric medications. They can provide personalized advice based on your medical history and current health status.

Moreover, if you experience any unusual symptoms, such as severe headaches, vision changes, or significant mood swings after starting or stopping any medication, it is crucial to seek medical attention promptly.
In summary, understanding the interactions between medications, recognizing the effects of emergency contraception, and knowing how to manage menstrual cycles after stopping birth control are vital aspects of reproductive health. Always consult with your healthcare provider for tailored advice and to ensure that your contraceptive methods align with your overall health needs.

Thank you for your questions, and I wish you the best in your health journey!
Best regards,
Doctor Q&A Teams
