Menopausal Hormone Replacement Therapy Issues
I am currently in menopause, and I have been on hormone replacement therapy for three months.
The first doctor prescribed me Premarin (estradiol 1mg + norethisterone acetate 0.5mg), and the second doctor prescribed me Provera (estradiol 1mg + norethisterone acetate 2.5mg).
I am 51 years old and have not yet reached menopause; I have been experiencing irregular periods for a year and a half, with cycles occurring approximately every 20 days, lasting about 3 days with light flow.
I also have two fibroids measuring about 1.8-2 cm.
I would like to ask: 1.
These two medications seem to have different doses of progestin; which one is more suitable for me? 2.
I noticed that the manufacturer’s information states that Premarin is intended for use after one year of menopause; is it appropriate for me to use it since I have not yet reached menopause? 3.
Are there lower doses of hormones available? I weigh less than others my age, approximately 45 kg.
Thank you, doctor!

Hello, the medication you mentioned can also be taken before menopause.
If there are side effects from taking 0.5 mg of progesterone, you may switch to a 2.5 mg dosage; however, the menstrual regulation effect may be less effective.
Thank you! Wishing you peace and health, Dr.
Zhang.

When considering hormone therapy for menopause, it's essential to understand the different formulations and dosages available, as well as how they may affect your body, especially given your current health status and symptoms.
1. Comparison of Medications: You mentioned two different medications: Banlena (estradiol 1mg + norethisterone acetate 0.5mg) and Shunlingna (estradiol 1mg + norethisterone acetate 2.5mg). The primary difference between these two is the dosage of norethisterone acetate, which is a form of progestin. The higher dose in Shunlingna may provide more endometrial protection, which is particularly important if you have a uterus and are taking estrogen. However, the increased dose can also lead to more side effects, such as mood changes or bloating. Given that you have fibroids, the choice of progestin may also influence your symptoms, as higher doses can sometimes exacerbate fibroid growth.
2. Timing of Hormone Therapy: Banlena is typically recommended for women who have been postmenopausal for at least a year. Since you are still experiencing irregular menstrual cycles and have not officially reached menopause, it may be more appropriate to consider Shunlingna, as it is designed for women who are still menstruating. However, this should be discussed with your healthcare provider, as they can assess your specific situation and determine the best course of action.
3. Lower Dosage Options: If you are concerned about the dosage, there are indeed lower-dose hormone therapy options available. For instance, some formulations provide lower doses of estrogen and progestin, which may be more suitable for women who are lighter in weight or have a lower body mass index (BMI). Given your weight of 45 kg, your body may metabolize hormones differently compared to women of average weight, potentially leading to a higher sensitivity to hormone therapy.
In addition to these considerations, it is crucial to monitor your symptoms closely. If you experience side effects such as headaches, mood swings, or any unusual symptoms, you should report these to your healthcare provider. They may need to adjust your dosage or switch you to a different formulation.
Furthermore, lifestyle modifications can also play a significant role in managing menopausal symptoms. Regular exercise, a balanced diet, and stress management techniques can help alleviate some of the discomfort associated with menopause.
Lastly, always ensure that any hormone therapy is closely monitored by your healthcare provider, especially considering your history of fibroids and irregular cycles. They can provide personalized advice and adjustments based on your ongoing health and response to treatment.
In summary, while both medications have their benefits, the choice should be tailored to your current health status, symptoms, and preferences. Discussing these points with your healthcare provider will help you make an informed decision that aligns with your health goals.
