Neulasta (Pegfilgrastim): Side Effects, Dosage, and More

What Is Neulasta’s Dosage?

Neulasta is a prescription drug. Your healthcare provider will prescribe the right dosage for you. You must always use the drug as prescribed by your doctor.

Forms and Strength

Neulasta is available as a liquid solution that can be administered as an injection in two ways:

  • From a syringe: Neulasta prefilled syringes are used for these types of injections. The drug is administered as an injection beneath the skin.
  • Through a special type of skin patch, known as Neulasta Onpro. The patch has a special on-body injector (OBI) that will be filled with the liquid form of Neulasta. The patch will be attached to your arm, back, or belly on the day you get chemotherapy. The drug will then be delivered into your body as an injection beneath your skin via a small cannula.

Neulasta is only available in one strength, which is 6 mg per 6 mL. It is important to note that Neulasta Onpro patch can only be used in taking chemotherapy medications that elevate the risk of serious infection. The patch is not effective in treating radiation sickness.

What Are The Recommended Dosages for Neulasta?

One of the most important factors to consider before prescribing a dosage is the type of condition you have. For instance, if you have severe infections during chemotherapy, your doctor will recommend taking Neulasta once in a chemotherapy cycle. The drug will not be administered in the 2 weeks before or the 1 day after you receive your chemotherapy dose.

If you have radiation sickness, your doctor will recommend taking two doses, which must be administered 1 week apart.
