Different insurance means different laws and different savings. For example, Medicare patients cannot use manufacturer copay cards (federal law) — but the manufacturer almost always has a Patient Assistance Program that gives the drug free.
About INFASURF and its cost
What is this medication? Infasurf is a prescription medication known as a calf-derived lung surfactant, specifically used for the prevention and treatment of respiratory distress syndrome in premature infants. This condition occurs when a newborn's lungs are not mature enough to produce sufficient natural surfactant, a substance that keeps the air sacs within the lungs open. By supplying this essential surfactant, Infasurf helps stabilize the infant's breathing and improves the transfer of oxygen into the bloodstream.
The medication is administered as a liquid suspension directly into the baby's windpipe by specialized medical staff in a hospital setting. It functions by lowering the surface tension on the alveolar surfaces, which prevents the lungs from collapsing during exhalation. Using this treatment can reduce the severity of lung disease and help lower the incidence of complications associated with premature birth.
INFASURF is made by a pharmaceutical manufacturer. Like most brand-name drugs, it's priced at a high list price — but patients rarely pay that list price. The options above are the real paths most people use to get it affordably.
Common questions
What's the cheapest way to afford INFASURF?
It depends on your insurance. On Medicare, apply for the manufacturer's Patient Assistance Program (PAP) — it gives the drug free if you meet income requirements. With private insurance, the manufacturer copay card usually drops your copay to $0-$25. Uninsured patients should compare the PAP with Cost Plus Drugs cash price.
Can I use a copay card with Medicare for INFASURF?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But the manufacturer has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover INFASURF?
Part D coverage varies by plan. We query the CMS Prescription Drug Plan file to show you what percentage of plans cover it and at what tier. For your exact copay, pick "Medicare" above and check your plan's Summary of Benefits, or log in to Medicare.gov.
How long does a Patient Assistance Program take?
Most PAPs take 2-6 weeks from application to first fill. Ask the manufacturer about a "bridge supply" — many will ship 30 days free while your application is being reviewed so you don't go without the drug.
What if I have a high-deductible plan?
For generics, Cost Plus Drugs cash price is often cheaper than your deductible-phase copay. For brand names, the manufacturer copay card almost always wins. A GoodRx coupon can be a last resort for uncovered drugs, but it doesn't count toward your deductible.
Are there charity grants for Respiratory Distress Syndrome?
Charities like HealthWell Foundation, PAN Foundation, Good Days, and the National Organization for Rare Disorders provide copay help for specific conditions. Funds often run out mid-year — apply early. We list the specific grants for your condition in the options above.
