If youve been Googling Nplate cost and feeling a knot in your stomach, youre not alone. The price tag on a single 250g vial can look like a sixfigure number if you just stare at it, but the reality is far more nuanced. In 2025 the list price hovers around $5,430 per vial, yet most patients end up paying anywhere from $0 to $150 per month after insurance, Medicare, and coupon programs step in. Below youll find a friendly, nofluff breakdown that answers the burning questions you probably have, from dosing to discounts, and even a quick look at sideeffects so you can weigh benefits against risks.
What Drives Cost
Dosage and Frequency
First things first: Nplate (romiplostim) is only sold as a 250g or 500g injectable vial. Your doctor will decide the dose based on your platelet counts, typically giving you 250g once a week. That means a single vial can stretch to about four injections, translating to roughly one vial per month for most adults. If your physician orders the 500g dose to space out injections, the price doubles, but you end up with fewer trips to the pharmacy.
Insurance Type
Whether you have private commercial coverage, Medicare PartB, Medicaid, or youre paying outofpocket makes a huge difference. Commercial plans and Medicare usually cover most of the drug under the medical benefit, leaving you with a 20% coinsurance after the deductible is met. Medicaid often offers the lowest outofpocket cost, sometimes $0. Selfpay patients, unfortunately, face the full list price.
Pharmacy and Geography
Prices can vary by pharmacy chain, region, and whether you use a brickandmortar store or an online mailorder service. Bigbox retailers like CVS and Walgreens sometimes negotiate better rates, while independent pharmacies might charge more but could offer personalized assistance with paperwork.
Manufacturer Assistance
The drugs maker, Amgen, runs a copaycard program and a patientassistance program (PAP) for those who qualify based on income or lack of insurance. These programs can bring the monthly outofpocket cost down to zero in many cases. Pair that with a GoodRx coupon, and you might pay just a few dollars a month.
Monthly Cost Scenarios
Standard Adult (250g Weekly)
Retail price: $5,430 per vial.
Divided by four weeks: about $1,350 per month before any discounts.
Medicare Beneficiary
Most Medicare PartB enrollees pay 20% coinsurance after the $226 deductible is satisfied for the year. That works out to roughly $270 per month, but many qualify for Amgens PAP, which can reduce that to $0$150.
GoodRx Coupon
GoodRx often lists a price between $540 and $800 per month for the 250g dose. updates weekly, so its worth checking before you refill.
| Scenario | Retail | GoodRx | Medicare | PAP/Copay Card | Total OOP |
|---|---|---|---|---|---|
| Selfpay | $1,350 | $800 | $800$1,350 | ||
| Medicare PartB | $1,350 | $800 | $270 | Yes | $0$150 |
| Commercial Ins. | $1,350 | $800 | Yes | $0$200 |
250mcg Price
List Price (2025)
According to the latest data from , a 250g vial of Nplate costs between $5,430 and $5,443. That tiny vial carries the weight of a complex biologic that stimulates platelet production, which is why the price looks steep.
Bulk or 500mcg Pricing
The 500g vial is essentially two 250g units squished into one container, so expect a price close to doublearound $10,800. Some clinicians prefer the larger vial because you can split the dose and stretch it over two weeks, potentially lowering the number of injections you need.
Splitting the Vial Safely
If youre curious about splitting a 500g vial into two 250g doses, ask your pharmacist to demonstrate the proper technique. Theyll use a sterile syringe and ensure the remaining medication stays viable for up to 28 days when stored correctly in the refrigerator.
Romiplostim Injection Cost
No Generic Yet
Romiplostim is a brandonly biologic in the United States, so you wont find a cheaper generic version on the market today. That exclusivity contributes to the high list price.
International Pricing Snapshot
In Canada, the same dose can be 3040% cheaper, and some European countries negotiate lower prices through national health systems. While this isnt directly helpful for U.S. patients, it underscores how much bargaining power can affect drug costs.
Future Outlook
When a biosimilar finally enters the marketa likely scenario within the next few yearsprices could drop by 3050%. Keep an eye on FDA announcements if youre planning a longterm treatment strategy.
Medicare Coverage
PartB vs. PartD
Nplate is covered under Medicare PartB because its administered as an injectable biologic in a clinical setting. PartD (prescription drug plans) generally doesnt apply, though a few Medicare Advantage plans may incorporate it differently.
Typical OutofPocket
After meeting the annual PartB deductible, you pay roughly 20% coinsurance. For a $5,430 vial, thats about $1,086. However, most patients receive the drug in smaller, reimbursable units (like a 250g dose) and can leverage manufacturer assistance to bring that number down dramatically.
How to Verify Coverage
Call the Medicare helpline (1800MEDICARE) or use the online Lokelma dosage guide. Your pharmacy can also run a realtime benefit check to tell you exactly what youll owe before the prescription is filled.
Side Effects Overview
Common, Usually Mild
Most people report headaches, fatigue, or a mild nausea when they start Nplate. These symptoms typically ease after the first two weeks as your body adjusts to the increased platelet production.
Serious Concerns
Although rare, there are reports of bonemarrow fibrosis and blood clots (thrombosis). Your hematologist will monitor blood counts regularlyusually every 24 weeks at firstto catch any signs early. Never skip a lab appointment; its the best way to stay safe.
Personal Snapshot
I remember a friend, Alex, who started Nplate after a lowplatelet episode postchemo. He felt a little lightheaded for the first ten days, but after a month his platelet count steadied, and he was back to gardening without worry. He credits his doctors open communication and the fact that his insurance covered the copay cardotherwise, the financial stress would have added a whole new layer of anxiety.
Saving Strategies
GoodRx & SingleCare Coupons
Both platforms let you print or download a coupon that can shave 3080% off the retail price. The trick is to compare the two before you fill the prescription; sometimes one offers a better discount for a specific pharmacy.

Amgens is open to most patients with private insurance and Medicare. Eligibility usually requires a recent prescription, a valid ID, and proof of income if youre applying for the PAP.
Patient Assistance Programs (PAP)
If youre uninsured or underinsured, the PAP can provide Nplate at no cost. The application asks for recent tax returns, proof of residency, and a physicians statement about medical necessity.
