chronic myelogenous leukemia
"I was on Gleevec for 6 months for CML and the side effects were horrendously painful, so my oncologist switched me to Dasatinib (which I have been on now for 10 months). I give it a "9" rating because there is no doubt about its effectiveness in killing the leukemia cells, but I didn't give it a "10" because of the side effects I am experiencing (which is more than others from what I understand). I have frequent headaches, bone pain, nausea, muscle pain and aches, gastrointestinal problems, occasional dry eye syndrome, constipation, severe anal sphincter pain, vertigo, extreme loss of energy and light headedness / dizziness, abdominal pain, gastritis, musculoskeletal pain and perhaps others that I do not yet recognize."
