Nypozi® Prefilled Syringe for Chemotherapy-Induced Neutropenia

Nypozi is a long-acting G-CSF used after certain chemotherapy to help reduce the risk of infection. This page explains what it is, how it is used, and how to handle the prefilled syringe safely. It also outlines ways to access treatment with US shipping from Canada and includes options for people without insurance.

What Nypozi Is and How It Works

Nypozi® contains pegfilgrastim, a granulocyte colony-stimulating factor. It helps your bone marrow make more neutrophils. Higher neutrophil counts can lower the chance of febrile neutropenia during myelosuppressive chemotherapy. The treatment is given as a single subcutaneous injection once per chemotherapy cycle. YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This medicine is a long-acting form of human G-CSF. It circulates longer than filgrastim due to pegylation, so one injection per cycle is usually sufficient. The treatment does not replace antibiotics or cancer therapy. It supports white blood cell recovery alongside your prescribed regimen. Learn about the condition it targets here: Neutropenia.

Who It’s For

This therapy is indicated to reduce the incidence of infection, as shown by febrile neutropenia, in patients receiving myelosuppressive anticancer drugs associated with a clinically significant risk of severe neutropenia. It is not appropriate for patients receiving chemotherapy for chronic myeloid leukemia or myelodysplasia. People with a history of serious allergic reactions to pegfilgrastim or filgrastim should not receive it.

Patients with sickle cell disease, those with a history of splenic issues, or with acute respiratory symptoms require careful evaluation by a clinician. Tell your prescriber about all medicines and health conditions before use. If you are on therapies for specific cancers such as Sprycel or Verzenio, your oncology team will decide whether a long-acting G-CSF is appropriate in your plan.

Dosage and Usage

Standard labeling recommends one subcutaneous dose per chemotherapy cycle. Administration is typically at least 24 hours after cytotoxic chemotherapy is finished. Follow the timing on the product label and your clinician’s instructions. Do not shake the syringe. Inspect the solution; do not use if cloudy or discolored.

Inject into the abdomen, thigh, or upper arm area with rotation of sites. Clean the skin with an alcohol swab and allow it to dry. Remove the needle cap just before use. Pinch the skin, insert the needle at the angle recommended by your prescriber, and deliver the full contents.

Strengths and Forms

This product is supplied as a single-dose prefilled syringe for subcutaneous use. Commonly available presentation includes: Pegfilgrastim 6 mg/0.6 mL syringe. Availability can vary by manufacturer and batch. Packaging and needle-safety features may differ. Check your carton and leaflet for component details.

Missed Dose and Timing

If a scheduled injection is missed around a chemotherapy cycle, contact your oncology team for guidance. Timing relative to chemotherapy matters. Do not attempt to “make up” a dose without advice. If an injection is given too close to chemotherapy, your clinician may adjust the plan for future cycles. Keep a written schedule to align administration with treatment dates.

Storage and Travel Basics

Store the prefilled syringe in a refrigerator as directed on the label. Keep it in the original carton to protect from light. Do not freeze. If the syringe has been frozen, follow the instructions in the leaflet or ask your pharmacist before use. Allow it to reach room temperature naturally before injection. Do not heat the syringe in a microwave, hot water, or direct sunlight.

When traveling, carry the syringe in an insulated container with coolant packs as instructed by your pharmacist. Keep it with you, not in checked luggage. Bring your prescription label and a copy of your medication list. Security staff may request documentation for medical supplies. For general self-injection reminders, see these tips: Inject Mounjaro Instructions. Our pharmacy uses temperature-controlled handling when required.

Pen Handling and Sharps Disposal

This therapy comes in a prefilled syringe, not a pen. Do not remove the needle cap until you are ready to inject. Do not recap after use. Place the used syringe in an FDA-cleared sharps container right away. If you do not have one, use a heavy-duty household container with a tight lid until you can obtain an approved sharps container. Follow local rules for sharps disposal. Keep all supplies out of reach of children and pets.

Benefits

This medicine helps prevent severe, prolonged neutropenia during certain chemotherapy regimens. Single-dose administration per cycle is convenient compared with daily short-acting options. It supports your treatment course by maintaining neutrophil counts, which may reduce interruptions due to infection risk. The prefilled syringe format simplifies preparation and dosing. Your oncology team will weigh benefits and risks based on your regimen and goals.

Side Effects and Safety

• Bone pain
• Pain in arms or legs
• Headache
• Injection site redness or discomfort
• Generalized aches

Serious but uncommon events can include splenic rupture, severe allergic reactions, acute respiratory distress syndrome, capillary leak syndrome, aortitis, glomerulonephritis, and sickle cell crises. Report left-sided abdominal pain or shoulder tip pain immediately. Tell your clinician about any breathing trouble, swelling, or severe skin reactions. Laboratory monitoring may include complete blood counts. See your product leaflet and official label for full safety details.

Drug Interactions and Cautions

There are no major drug–drug interactions commonly listed for pegfilgrastim, but clinic timing with cytotoxic chemotherapy is critical. Do not administer too close to chemotherapy administration unless directed. Use caution in patients with pre-existing spleen enlargement or underlying pulmonary conditions. Inform your prescriber about recent radiation therapy to bones or chest. For background on related hematologic conditions, see What Is Leukemia.

What to Expect Over Time

After injection, the medicine begins supporting neutrophil production during the post-chemotherapy nadir. Bone pain may occur within days and often improves with supportive care recommended by your team. Your clinician may schedule blood tests to track counts and adjust your treatment plan. Consistent timing each cycle helps maintain predictable support. Use a calendar or reminder app to align injections with chemotherapy dates. If you experience unexpected symptoms, contact your oncology clinic promptly.

Compare With Alternatives

Within this class, alternatives include the reference product Neulasta and several pegfilgrastim biosimilars such as Fulphila and Udenyca. Selection depends on availability, coverage, and clinic protocols. All are long-acting G-CSFs used to reduce febrile neutropenia risk in eligible patients. Your prescriber will choose the option that fits your regimen and access needs. You can also browse class information by condition here: Neutropenia.

Availability and Substitutions

Supply can vary. If a specific presentation is temporarily unavailable, your prescriber may recommend a therapeutically equivalent alternative from the same class. Our Nypozi online pharmacy listing reflects current stock status when you submit your prescription. We cannot guarantee future inventory or restock dates. Your care team has final say on substitutions.

Patient Suitability and Cost-Saving Tips

This therapy may suit adults receiving myelosuppressive chemotherapy who have a clinically significant risk of febrile neutropenia. It is not for primary prophylaxis in regimens without that risk. People with prior severe hypersensitivity to G-CSFs should avoid it. If eligible, ask about multi-cycle fills to reduce refill frequency. Sign up for reminders so you have medicine ready before each chemotherapy cycle.

To manage Nypozi cost, discuss supply lengths and the manufacturer version your prescriber recommends. Compare Canadian pricing with your local options. Bring your prescription details when requesting a quote. If you are paying cash, ask your clinician whether a biosimilar presentation in the same class is appropriate for your regimen.
