The Neulasta shot can be covered by the pharmaceutical company if you do not have insurance. I do not have insurance and all my medication for treatments are done by the parent pharma companies. You have to not make more than 75-120K (not a problem for me, lol), not qualify for medicaid, and not have any kind of insurance. Each chemo session for me totals 22K dollars in meds each time :)
I had low WBC before treatments began and after the first treatment/shot my WBC jumped into normal range. The shot is painless when given in the tummy (the arm will leave you feeling like you had a flu shot..ugh) and it promotes the regeneration of white blood cells in your bones (your bones produce histamines during the regen which causes the pain in long bones) over a period of 10 days or so. Drinking lots of water and taking Claritin/Zyrtec/Benedryl twice a day beginning the day before and continuing for several days after will dramatically help with the pain associated with the regen. Tylenol or Advil for normal pain and a Tramadol or Vicodin for a couple of days during the worst of the pain is also good idea. I take a Zyrtec during the day and a Benedryl at night (helps sleep through the discomfort) and this regimen works well for me.
I hope you find a working solution for you soon!
