Weekly Chemo and Neupogen. If you are having weekly, low-dose chemotherapy, Neulasta is not an option. Since Neulasta must be given 24 hours after chemo, and 14 days before the next cycle, it won't work with weekly infusions. Neupogen will work fine with weekly chemo, since it clears your system fairly quickly, and can be given as often as you need it between chemo cycles.
