Thanks so much for the info. Sorry, I didn't fully explain my situation. I have been on abiraterone for 5 1/2 years. In the beginning the side effects were bad, with time much better. The point I was trying to make that abiraterone is made by a number of manufacturers and like any medicine, depending on the Indvidual the side effects will vary. When I changed from private insurance to Medicare my insurance company now is dictating what medicine(manufacture) in this case apotex. I have tried before, and the side effects were thru the roof. When I asked for the medicine, I was taking before, they told me they can't regardless of if you can tolerate or not. Company policy not patient care.
