After a woman stops treatment with leuprolide, menstruation will resume in about 1-3 months. Leuprorelin is a luteinizing hormone-releasing hormone, which reduces the responsiveness of the pituitary gland and suppresses gonadal function, causing women to experience menorrhagia and amenorrhea, and can be used to treat menstrual irregularities as well as endometriosis. Women are treated with one injection per month on the first day of menstruation and one injection every 28 days, requiring 3-6 cycles of injections, which can be very effective. Most women do not experience any discomfort after the injection, but only a small number of women may experience perineal discomfort, sweating, etc. During this period, women should pay attention to maintaining a regular life, avoiding physical exertion, increasing nutrition, and giving appropriate symptomatic treatment to alleviate the symptoms.
