My mom was scheduled for her 6th treatment yesterday only to find out it was delayed 1 week due to chemo related anemia. They gave her a shot of aranesp. I am curious to know if anyone has taken this and how long does it actually start to take effect? We were under the impression that her extreme fatigue, muscle weakness, and various other complaints were due to the cumulative effects of the chemo, we had no idea to look for signs of anemia. Thank you all in advance for any help/advice you can give.
