Abiraterone can cause serious fatigue. Increasing prednisone to 7.5mg can make a big difference. The standard dose of prednisone is either five or 10 mg with Zytiga.

If there was just a little bit of fatigue than 7 1/2 would probably do. I was working with a guy who would wake up and have to go back to sleep for three hours because Zytiga was just exhausting him. He moved up to 10 mg and it helped a lot.

At one of the conferences, I went to a Doctor discussed his prostate cancer problems, he had a lot of fatigue so he moved up to 7 1/2 mg of prednisone And was happy with that. Unfortunately, it raised his blood sugar so he had to drop back down. Something to be aware of.

I know some people that have had their standard dose set to 10 mg when they were given prednisone with Abbie. Just depends on what the doctor likes to do.

Something to discuss with your doctor.
