After Sprycel dropped my WBC count down to 1.6 (and .5 absolute neutraphil count), my doctor asked me to hold on the medication to allow my counts to go back up. After my neutrphil count went from .5 to .7, it suddenly went back down to .5 over the span of 10 days-ish. All my other blood counts are marching up as expected to more normal ranges (HGL, RBC, platelets, etc.). I have a feeling that I'm more concerned than I should be because I'm getting labs twice a week - and getting too wrapped up in the lab-to-lab results rather than seeing the bigger picture. What I'm wondering is if this is a common experience when first starting Sprycel? I know it's not uncommon for the values to drop and having to then calibrate to taking the drug, but I'm wondering why my WBC count would not be moving and actually dropping despite having been off Sprycel for 10 days.
