How much does filgrastim cost in the U.S.?
Prices for filgrastim vary a lot by brand/product, dose (how many micrograms or milligrams), number of doses, pharmacy, and insurance coverage. The only reliable way to get the current out-of-pocket cost is to check live pricing at a specific pharmacy (or your insurer’s formulary).
What factors make filgrastim price differ by patient?
Common drivers include:
- Which filgrastim product you use (brand vs biosimilar).
- Dose and dosing schedule (cost scales directly with total vials or syringes used).
- How it’s dispensed (single-use prefilled syringe vs vial).
- Insurance status (commercial insurance vs Medicare vs no insurance) and copay/coinsurance.
- Whether a patient is using a pharmacy benefits manager (PBM) and whether prior authorization is required.
Can you estimate cost per dose if you tell me the regimen?
Yes. If you share:
- the exact product name you’re using (brand or biosimilar),
- the prescribed dose (e.g., 300 mcg, 480 mcg, 5 mcg/kg),
- number of injections per day (often once daily),
- and how many days you’ll need,
I can help you convert that into a “total dose” and typical quantities used (vials/syringes), so you can map it to a pharmacy price.
If you want a quick range: what should you check today?
To find today’s cost for your exact situation, look up the drug and strength on one or more of the following:
- Your pharmacy’s price (ask for cash/self-pay if you’re uninsured or before applying insurance).
- Your insurance’s preferred drug list (copay/coinsurance).
- Discount programs if eligible (some copay cards don’t cover non-insured patients).
What I need to give you a real number
Reply with:
1) your country (U.S. or elsewhere),
2) the product (name on the box or prescription, e.g., Zarxio or Neupogen or another filgrastim),
3) strength per syringe/vial and your dose,
4) how many days/injections planned,
and I’ll help you compute total quantity and explain what price range is most likely for that regimen.
