Introduction

In general, when taking dydrogesterone tablets to regulate the menstrual cycle, menstruation usually occurs 2 to 5 days after discontinuation of the medication. This timeframe may vary somewhat between individuals. If abnormalities occur, prompt medical attention is recommended. If menstruation has not occurred one week after stopping the medication, and pregnancy has been ruled out, it is advisable to visit a hospital for further examination.

Generally, when taking dydrogesterone tablets to regulate the menstrual cycle, menstruation usually occurs 2 to 5 days after discontinuation of the medication. This timeframe may vary among individuals. If any abnormalities occur, prompt medical consultation is recommended. Detailed explanations are as follows:

In young women of reproductive age, after discontinuation of the medication, the progesterone levels in the body decline rapidly. Once the endometrium loses support from progesterone, withdrawal bleeding—i.e., the onset of menstruation—typically occurs within about 2 to 3 days.

For women over 40 years old, ovarian function gradually declines, and hormonal changes in the body may be relatively slower. Therefore, after stopping the medication, it may take about 3 to 5 days for the progesterone levels to drop sufficiently to trigger menstruation.

It is worth noting that if dydrogesterone tablets are taken for fetal preservation treatment in patients with threatened abortion, menstruation may not occur immediately after discontinuation, because the purpose of progesterone supplementation is to support the pregnancy.

If menstruation has not occurred within a week after stopping the medication and pregnancy has been ruled out, it is recommended to visit a hospital for further examination to exclude other potential health issues, identify the underlying cause, and implement appropriate treatment measures.

In general, dydrogesterone tablets are a progestin medication. Whether menstrual bleeding during dydrogesterone use is normal depends on the purpose of treatment and the characteristics of the bleeding, and should be evaluated accordingly. If abnormal bleeding occurs, medical advice should be sought promptly. The medication should be taken as prescribed by the doctor in terms of dosage and timing; do not discontinue or adjust the dose without consultation. Maintain good external genital hygiene by washing with warm water.

Will progesterone levels increase after taking dydrogesterone tablets?

In general, after taking dydrogesterone tablets, blood tests for progesterone levels usually do not show a significant increase. Be sure to take the medication exactly as prescribed by your doctor, without adjusting the dose or stopping the medication on your own. If hormone levels need to be monitored during treatment, inform your doctor in advance that you are taking dydrogesterone, so that the doctor can make a comprehensive assessment based on clinical symptoms.

Can I take dydrogesterone tablets if I have uterine fibroids?

If uterine fibroids are less than 5 cm in diameter, grow slowly, and the patient has no obvious symptoms such as heavy menstrual bleeding or abdominal pain, and if the patient also has conditions like menstrual irregularity or low progesterone levels in early pregnancy requiring fetal preservation, oral dydrogesterone tablets may be prescribed for short-term use after physician evaluation. In such cases, the medication primarily serves to regulate hormones and maintain pregnancy, with minimal impact on the fibroids.
