Does evista (raloxifene) have adverse side effects if a person takes it more than 5 years?

Perhaps: Evista (raloxifene) if taken to reduce breast cancer in post-menopausal women is usually taken just for 5 years but there is no limit number of years if taken for osteoporosis. There may be an increase risk of ovarian cancer the longer it is taken. Increased risk of stroke or blood clots is not necessarily related to duration of intake.
