I am on Tamoxifen myself. Take as your doctor perscribes..
When and if the doctor tells you Tamoxifen is a "24 hour" pill he is not kidding! Make sure you keep yourself on a schedule when you take it, the side effects are very noticible when it starts to make it's way out of your system. If I were you I wouldn't let more than 20 hours go between the doses if you're only taking one a day. I am on 75mg 3x/day
Take this med as directed by your prescribing physician.
