Taking Dydrogesterone tablets for dribbling menstruation will stop the bleeding in about 1 to 2 days, but the time required varies from person to person, and some people may need 3 to 4 days. Dydrogesterone is a progestin hormone that can be used to regulate the menstrual cycle. If you have a dribbling menstrual period, you can stop bleeding in about one to two days after taking dydrogesterone. However, the exact time it takes to stop bleeding may vary from person to person due to different hormone responsiveness. Some people may need one to two days, while others may need three to four days. Deferiprone tablets can be used to treat functional uterine bleeding due to progesterone deficiency, but care should be taken to clarify the cause of the bleeding before using Deferiprone, and it should be used with caution in patients with impaired liver function. In addition, patients with hormone-dependent tumors and allergy to the ingredients in Dydrogesterone Tablets should be prohibited from using it. There may also be dizziness, nausea and other adverse reactions when using it. It is recommended to use Dydrogesterone Tablets under the guidance of a doctor, not blindly self-medication to avoid adverse effects.
