menorrhagia
"I have used Lysteda 2x now with great success. It has slowed down and then stopped my menstrual cycle within 4 doses. I am a bit concerned that one of the possible side effects could be blood clots. I personally have not had any. However, because I am an RN, I have realized that the side effects of this drug could be scary if not used EXACTLY as the doctor has prescribed and at the time intervals prescribed. I have had headaches each time that I have used it but I also suffer from  migraine headaches. For me, the headaches are a worth the benefit that Lysteda provides. Just make sure that the directions for use are followed completely and report any odd/new symptoms to your doctor."
