how long does it take for wbc counts to increase
These drugs lower the white blood cell count to a greater degree than the counts of other blood cells â red blood cells and platelets â although these are commonly affected, too. Fortunately, the effect of these drugs on the white blood cell count is usually both predictable and short-lived. The white cell count generally falls below the normal range about seven to ten days after a chemotherapy treatment and recovers within about a week after that.
