Concerns About Progesterone Use After Miscarriage: Risks and Alternatives - Obstetrics and Gynecology

What are the issues related to taking progesterone?


Hello Doctor, I experienced a miscarriage due to a stopped fetal heartbeat at the beginning of October and used misoprostol for the process.
In mid-November, I had a light menstrual period that lasted for two weeks, followed by heavier bleeding with large blood clots until last week.
The doctor prescribed me hemostatic medication along with estrogen and progesterone, and currently, the bleeding has stopped.
The doctor also prescribed NORINA (norethisterone) to be taken twice daily for two weeks.
Since this medication is a synthetic progesterone, I am concerned about potential side effects because I have uterine fibroids and breast fibrocystic changes.
I read online that it could lead to breast tumors, among other issues.
My question is, if I take this medication for a short term (for example, two pills a day for three weeks), will it increase risks or have any negative effects? Are there any natural progesterone alternatives available? Or are most common menstrual-regulating progesterones similar to this type? Thank you for your patient response; I greatly appreciate it.

Hello, the doctor just wants to monitor your bleeding situation; this is only for short-term use, so there's no need to worry.
If you have any further concerns, you can consult your regular obstetrician-gynecologist.
Wishing you good health.

More Info


After experiencing a miscarriage, it is common for patients to have concerns about the use of progesterone, particularly synthetic forms like Norina (which contains synthetic progestin). Your concerns about potential side effects, especially given your history of uterine fibroids and breast cysts, are valid and warrant a thorough discussion.


Understanding Progesterone and Its Use After Miscarriage
Progesterone plays a crucial role in maintaining pregnancy. After a miscarriage, doctors may prescribe progesterone to help regulate the menstrual cycle and prepare the uterine lining for future pregnancies. Norina, as a synthetic progestin, mimics the effects of natural progesterone but can have different side effects.


Potential Risks and Side Effects
1. Hormonal Effects: Synthetic progestins can sometimes lead to side effects such as breast tenderness, mood swings, and changes in menstrual bleeding patterns. In some cases, they may also contribute to the development of breast lumps or exacerbate existing conditions like fibrocystic breast disease.

2. Uterine Fibroids: There is a concern that hormonal treatments can influence the growth of uterine fibroids. While progestins are often used to manage symptoms associated with fibroids, they can also stimulate their growth in some women. If you have a history of fibroids, it is essential to monitor their size and symptoms while on hormonal therapy.

3. Breast Cysts: Similar to fibroids, breast cysts can be influenced by hormonal changes. While there is no direct evidence that synthetic progestins cause breast tumors, they can lead to changes in breast tissue that may be concerning for those with existing cysts.


Short-Term Use and Alternatives
Taking Norina for a short period, such as three weeks, is generally considered safe for most women, especially under medical supervision. However, it is crucial to have regular follow-ups with your healthcare provider to monitor any side effects or changes in your condition.

If you are concerned about the risks associated with synthetic progestins, you might consider discussing the following alternatives with your doctor:
1. Natural Progesterone: Natural progesterone, derived from plants, is available in various forms, including creams and capsules. Some women prefer this option, believing it to be safer and more compatible with their bodies. However, the efficacy and safety of natural progesterone can vary, and it is essential to use it under medical guidance.

2. Lifestyle Modifications: Incorporating lifestyle changes such as a balanced diet, regular exercise, and stress management techniques can help regulate hormonal levels naturally. Some studies suggest that a healthy lifestyle can positively impact menstrual cycles and overall reproductive health.

3. Monitoring and Regular Check-Ups: Regular check-ups with your healthcare provider can help monitor the effects of any hormonal treatment and manage any side effects promptly. This is particularly important if you have pre-existing conditions like fibroids or breast cysts.


Conclusion
In summary, while synthetic progestins like Norina can be beneficial after a miscarriage, they do come with potential risks, especially for individuals with a history of uterine fibroids and breast cysts. Short-term use is generally considered safe, but it is crucial to maintain open communication with your healthcare provider about any concerns or side effects you may experience. Exploring alternatives, such as natural progesterone, and implementing lifestyle changes can also be beneficial. Always consult your doctor before making any changes to your medication or treatment plan.
