Hi @jeis68 A low neutrophil count after any illness, whether viral or bacterial, isn’t uncommon. Unless you have an underlying condition that is compromising your immune system your neutrophil count should naturally begin to regenerate.

It’s my understanding, Neupogen isn’t typically used to treat something like flu symptoms. However, to answer your question, Neupogen is very effective in increasing the white blood cell production in the bone marrow. (IF your doctor does prescribe this injection, the side effects can be very painful. A suggestion from personal experience is to take a Claritin antihistamine capsule daily (not Claritin D) for a good week or more after the injection. (With your doctor’s ok). This is standard in the world of blood cancer patients to help mitigate the discomfort caused by the rapid increase of cells)

How long have you had the low blood count? Do you have any prior diagnosed medical conditions?
