Hi @bettersleep68 I just wrote a reply to your other comment regarding low WBC here: https://connect.mayoclinic.org/comment/1273884/

Here’s the cut/paste version:
It’s not unusual mid cycle for blood numbers to drop. Basically, chemo targets quickly dividing cells, such as cancer cells. But it’s not discriminatory so it can impact all of the rapidly dividing cells such as red/white/platelets, mucosal lining of stomach, intestines, mouth, hair follicles and nails. During mid month the drop reaches a low point called neutropenia or nadir. At least for me, that was several days of low mental and physical energy. Then the numbers start to climb again, just in time again for the next round of chemo.

It’s not uncommon for a drug such as Neupogen or Neulasta to be administered the day following the last day of a chemo round. These meds can promote faster neutrophil production. These WBC’s are important for fighting infection.
During this time of neutropenia, be vigilant for any sign of infection such as a fever. If you develop a fever of 101.3 let your cancer team know right away.

Has your doctor mentioned an injection of Neulasta?

My wbc count was in the normal range after the third round however in the first two rounds they were between 0.8 and 1.5. Now in my forth round they are down again to 1.3. So my treatment is on hold until they return to normal which my doctor assured me they will. In the meantime I use caution, for example avoid people with colds take antibiotic (LEVOFLOXACIN). In addition during first 3 rounds I took antiviral (ACYCLOVIR) and anti fugal (POSACONAZOLE).
