"Reduces heavy menstrual bleeding by an average of 90% after the first few months of use.
Reduces menstrual bleeding and cramps and, in many women, eventually causes menstrual periods to stop altogether. In this case, not menstruating is not harmful. May effectively relieve endometriosis and is less likely to cause side effects than high-dose progestin. Reduces the risk of ectopic pregnancy. Does not cause weight gain."
