What medications are effective for irregular menstruation?

Common types of menstrual irregularities include cycle disorders, excessive or insufficient menstrual flow. If the irregularity is functional, medications to regulate menstruation may be considered, such as Chinese herbal medicine or Western medicines like progestins to help adjust the cycle and stabilize the endometrium. If the menstrual irregularity is caused by hormonal imbalances, ovulation-stimulating drugs or oral contraceptives might be needed to regulate hormone levels. When organic diseases such as uterine fibroids or endometriosis are responsible, surgical treatment combined with medication may be necessary. Generally speaking, the following medications may be effective:

1. Xiaoyao Pills: Composed of ingredients such as Poria (Fu Ling) and ginger (Sheng Jiang), these pills nourish the blood and vital energy (Qi) and help regulate menstruation and relieve pain. They are suitable for menstrual irregularities caused by impaired liver Qi circulation.
