Pegfilgrastim (
Neulasta®) is a prescription medication used to prevent infections in people undergoing certain kinds of chemotherapy. Many types of chemotherapy increase the risk of dangerous infections, and pegfilgrastim can help prevent such infections.
As with any medicine, side effects are possible with pegfilgrastim.
However, not everyone who takes the drug will experience problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
Common side effects of pegfilgrastim include, but are not limited to:
Hair loss is common in people taking this medication, but is most likely due to the chemotherapy, rather than to pegfilgrastim
(see Neulasta and Hair Loss).
