Why did nuelasta not work after chemo. my wbc was 2.9 and i had to delay. anc number was good. this was my first round and never had nuelasta.

Could be worse: Nulasta is a long-acting form of GCSG (filgrastim) that reduces the duration and depth of low white blood cell count (WBC), particularly the neutrophil count (ANC) after chemotherapy. It won't completely prevent a WBC drop, so the dosage or timing of subsequent rounds of chemotherapy may need to be adjusted, in individual cases.
