Inquiry about menstrual regulation medications?


Hello Doctor, six months ago my menstrual cycle became irregular.
I consulted a gynecologist who indicated that I have a tendency towards polycystic ovary syndrome.
The doctor prescribed "Winstop 28" and "Novamin" for me, and during this period, my menstrual cycle has been very regular.
Last month, the doctor suggested that I stop the medication for a month to see what happens.
Two weeks after my period ended, I started bleeding again, so I urgently went back to see the doctor, who prescribed "Strocaine" for me.
I mainly want to ask Dr.
Tsao if the first medication is a menstrual regulation medication, which is a form of oral contraceptive? And do the second and third medications help reduce nausea? Thank you for your response, Doctor.

Hello, the first one is to avoid medications that are also menstrual regulators, and the second is gastrointestinal medications.
Wishing you good health.

More Info


Menstrual regulation medications can be quite complex, especially when dealing with conditions like polycystic ovary syndrome (PCOS). Based on your description, it seems you have been prescribed a combination of medications to help regulate your menstrual cycle and manage symptoms associated with your condition.

1. Understanding WINSTOP28: WINSTOP28 is a type of combined oral contraceptive pill (OCP) that contains both estrogen and progestin. These pills are often used not only for contraception but also for regulating menstrual cycles. They can help in managing irregular periods, reducing menstrual cramps, and even alleviating symptoms of PCOS. By taking WINSTOP28, you are essentially using it as a menstrual regulation medication, which is a common practice in managing conditions like PCOS.
2. Role of Novamin: Novamin (also known as norethisterone) is a progestin that can be used to help regulate the menstrual cycle. It is often prescribed to manage heavy menstrual bleeding or to delay periods. In your case, it may have been used in conjunction with WINSTOP28 to provide additional hormonal support and help stabilize your cycle.

3. Strocaine: This medication is typically used to alleviate nausea and vomiting. If you were experiencing nausea as a side effect of the hormonal medications or due to your menstrual irregularities, your doctor may have prescribed Strocaine to help manage those symptoms. It’s important to communicate any side effects you experience while on these medications, as they can sometimes be managed with additional treatments.

4. Why Did Your Period Start Again After Stopping the Medications?: It’s not uncommon for women with PCOS to experience irregular bleeding even after a period of regulation with medications. Stopping the hormonal medications can lead to a withdrawal bleed, but if your body is still adjusting to the hormonal changes, it may result in unexpected bleeding. This is why your doctor may have prescribed Strocaine to help manage any discomfort associated with this bleeding.

5. Next Steps: If your menstrual irregularities continue or worsen, it’s essential to follow up with your healthcare provider. They may consider adjusting your medication regimen or exploring other treatment options. Lifestyle changes, such as maintaining a healthy weight, regular exercise, and a balanced diet, can also play a significant role in managing PCOS symptoms.

In summary, the medications you are taking serve different purposes: WINSTOP28 is primarily for menstrual regulation and contraception, Novamin helps with hormonal balance, and Strocaine is for managing nausea. It’s crucial to maintain open communication with your healthcare provider about your symptoms and any side effects you experience, as this will help them tailor your treatment plan to best suit your needs. Always consult your doctor before making any changes to your medication regimen.
