Adenomyosis uterus shrinking injections usually refer to injections of gonadotropin-releasing hormone agonists, which are available from the first to the fifth day of menstruation, and the first injection is usually recommended on the first day of menstruation. This injection can significantly reduce the size of the uterus and relieve the condition of adenomyosis. The first injection is usually recommended on the first day of menstruation, and then the injection is given at intervals of 28 days, and the injection is discontinued after 3-6 months. It should be noted that such injections will reduce estrogen and may cause menopause-related symptoms. If the symptoms are severe enough to affect your life, medication may be prescribed. Those suffering from adenomyosis should consult a doctor in time and take the correct way and time to inject the medication under the doctor’s guidance, avoiding unauthorized use of medication.
