About Ravicti and its cost
What is this medication? Ravicti is a prescription liquid medication used for the long-term management of urea cycle disorders in adults and children. These genetic conditions occur when the body lacks certain enzymes needed to remove nitrogen, a waste product of protein metabolism. When nitrogen is not properly processed, it builds up in the blood as ammonia, which can cause severe neurological damage or other life-threatening complications. Ravicti is prescribed when the condition cannot be controlled through a protein-restricted diet or amino acid supplements alone.
The medication works as a nitrogen-binding agent that helps the body eliminate excess nitrogen through the kidneys. By providing an alternative pathway for waste removal, it helps maintain safe ammonia levels in the bloodstream. It is important to note that Ravicti is intended for chronic, daily use and is not used to treat acute hyperammonemia, which is a medical emergency characterized by a rapid and dangerous spike in ammonia. Patients using this treatment must typically follow a specialized diet and undergo regular blood tests to monitor their condition.
Ravicti is made by Amgen. 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 Ravicti?
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 Ravicti?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Amgen has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover Ravicti?
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 Urea Cycle Disorder?
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.
