Oral contraceptives
Hello Doctor: I have polycystic ovary syndrome, and the doctor mentioned during the ultrasound that one ovary is more severely affected.
I had been taking "Mei Shi Nong" for menstrual regulation in March, April, and May, which was prescribed by my first gynecologist.
I stopped the medication in June, and my last menstrual cycle was from June 12 to June 17.
Naturally, I did not have my period in July.
Currently, on August 13, I noticed a little bleeding, and as of today, August 15, the amount is still very minimal, with a dark brown, thick consistency (similar to the end of a previous menstrual period), unlike the bright red and heavier flow I experienced in the previous months when I was taking the medication from March to May, during which the flow was normal.
I visited a gynecologist today, who performed an ultrasound and said everything was fine, and prescribed "Nina Enteric-Coated Tablets." However, I am hesitant to take it because I have been on "Mei Shi Nong" for a long time.
Therefore, I would like to ask you, is "Nina Enteric-Coated Tablets" better than "Mei Shi Nong"? Thank you!

More Info
When it comes to understanding the differences between Mei Shi Nong (美適濃) and Nina (妮娜膜衣錠) birth control pills, it's essential to consider several factors, particularly in the context of your health condition, such as polycystic ovary syndrome (PCOS).
1. Composition and Mechanism of Action:
Both Mei Shi Nong and Nina are hormonal contraceptives, but they may contain different active ingredients and hormone dosages. Mei Shi Nong typically contains a combination of estrogen and progestin, which work together to prevent ovulation, regulate menstrual cycles, and reduce the risk of endometrial cancer. Nina, on the other hand, may have a different formulation, possibly with a lower dose of hormones or a different type of progestin. This can affect how your body responds to the medication, especially if you have PCOS, which can complicate hormonal balance.
2. Side Effects and Tolerance:
The side effects of hormonal contraceptives can vary significantly between individuals and between different brands. Some women may experience weight gain, mood changes, or breakthrough bleeding with one type of pill but not with another. Since you have been on Mei Shi Nong for several months, you may have developed a tolerance to its side effects. Transitioning to Nina could result in different side effects, which might be more or less tolerable for you. It’s crucial to monitor how your body reacts to any new medication.
3. Effectiveness in Managing PCOS:
For women with PCOS, managing symptoms such as irregular menstrual cycles and hormonal imbalances is vital. Both Mei Shi Nong and Nina can help regulate menstrual cycles, but their effectiveness can vary based on individual hormonal profiles. Your healthcare provider may have specific reasons for prescribing Nina, such as its potential benefits in managing your symptoms more effectively or reducing side effects you may have experienced with Mei Shi Nong.
4. Personal Health Considerations:
Given your history of irregular menstrual cycles and the recent changes in your bleeding patterns, it’s essential to discuss your concerns with your healthcare provider. The fact that you experienced a lighter, darker discharge could indicate hormonal fluctuations, which are common in women with PCOS. Your doctor’s recommendation to switch to Nina may be based on their assessment of your current health status and the need for a different hormonal approach.
5. Consultation and Monitoring:
Before making any changes to your medication, it’s advisable to have an open discussion with your healthcare provider about your concerns regarding Nina. Ask about the specific benefits of switching from Mei Shi Nong to Nina, how it may affect your PCOS symptoms, and what side effects to expect. Additionally, regular follow-ups after starting a new contraceptive are crucial to monitor your response and make any necessary adjustments.
In conclusion, while both Mei Shi Nong and Nina are effective contraceptive options, their suitability for you may depend on your individual health needs, how your body responds to hormonal changes, and your specific symptoms related to PCOS. Always prioritize open communication with your healthcare provider to ensure that you make informed decisions about your reproductive health.
