Hi @shmerdloff Absolutely, call your Oncologist office or go to the ER. It most likely isn’t the Neulasta causing the fever.
If you had your chemo a week ago, your blood numbers, especially the neutrophils, may be dropping, leaving you at risk for infection.

When I was undergoing chemo, whenever my temperature got to 100.4 I was instructed to call my oncologist ASAP or head to the ER for IV antibiotics. I was then admitted for a week for the IV antibiotics and monitoring. This is a standard protocol for anyone undergoing chemo.

So please call your doctor. There should be someone on call to give you guidance. Let me know what you find out, ok?
