Here’s my take on Evista ..because I did check this out. It depends on where your osteoporosis is … for example, if you have a high dexa score in your vertebrae, this drug is good. But if you have high scores elsewhere, such as hips, this drug is not effective in preventing fractures. Also this drug comes with risks. “This medicine may increase your risk of a blood clot in your leg, your lung, or your eye. You should not take Evista if you have ever had this type of blood clot.”
