Neulasta studies

Home Treatments Lifestyle Symptoms

Neulasta® is a prescription medication often referred as a white cell booster as it stimulate the production of white cells in the bone marrow. These are released into the blood stream increasing and maintaining the white blood count and hence reducing your risk of infection. A low white cell count can also delay your chemotherapy or keep you from getting your full dose. This white cell booster therefore gives you a better chance of being able to stick to your chemotherapy schedule, which most doctors agree is a great advantage to the success of your treatment. Several well conducted international studies, listed below have proven the effectiveness of Neulasta over no medication at all or the previously commonly used white cell booster Neupogen:.
