Timing for taking contraceptive pills after discontinuing antihistamines?
Hello, doctor.
I have been taking Dydrogesterone and have finished two boxes.
My menstruation during the second month (while taking the second box) has been delayed for over ten days, and I believe I have entered an amenorrheic state.
This month, I would like to stop the medication and switch to taking oral contraceptives.
I read online that it may take 2 to 3 months for menstruation to return to normal after stopping the medication, and that oral contraceptives should typically be started when menstruation begins.
Could you please advise me on when to start taking the contraceptive pills during this amenorrheic period?

Hello, the purpose of taking oral contraceptives should be considered.
If you intend to use them for contraception, it is recommended to use condoms as well.
However, if you are looking to use the contraceptive pill to treat a medical condition, you should start taking the pill on the fifth day of your menstrual cycle.
Wishing you good health.

When considering the timing for starting birth control after discontinuing Eptoin (Ethosuximide), it's essential to understand how hormonal contraceptives work and the implications of your current situation. Eptoin is primarily used for managing epilepsy, and its discontinuation can lead to various hormonal changes in your body, particularly if it has affected your menstrual cycle.
Firstly, it is important to note that the absence of menstruation (amenorrhea) after stopping Eptoin may not necessarily indicate that your body is ready to start a new hormonal contraceptive method. The hormonal balance in your body may still be adjusting, and it can take some time for your menstrual cycle to normalize. While some sources suggest that it may take 2-3 months for your cycle to return to its regular pattern after stopping certain medications, this can vary significantly from person to person.
If you are considering starting a birth control pill during a period of amenorrhea, it is generally recommended to consult with your healthcare provider. They can provide personalized advice based on your medical history and current health status. In many cases, if you are not experiencing a menstrual period, you can still start taking the birth control pill. However, it is crucial to understand that starting the pill without a menstrual cycle may not provide immediate contraceptive protection. Most healthcare providers recommend using a backup method of contraception, such as condoms, for the first seven days after starting the pill.
Additionally, if you have concerns about your menstrual cycle and the timing of starting birth control, your healthcare provider may suggest waiting until your cycle resumes before starting the pill. This approach can help ensure that you have a clearer understanding of your cycle and can help in tracking your periods more effectively.
In summary, while you may be able to start taking birth control pills during a period of amenorrhea, it is essential to consult with your healthcare provider for tailored advice. They can help you navigate the transition from Eptoin to birth control, ensuring that you are protected against unintended pregnancy while also monitoring your menstrual health. Remember that every individual's body responds differently to hormonal changes, and professional guidance is invaluable in making informed decisions about your reproductive health.
