Ganaxolone price?

What’s the U.S. list price of Briviact (ganaxolone)?
Briviact’s manufacturer lists the monthly cost at roughly $20,000 for a typical adult dose. That figure appears in the FDA label and in the drug’s official pricing sheets.[1]

How much does a patient actually pay after insurance?
Most U.S. insurers cover a large portion of antiepileptic drugs, but copays and deductibles can still reach several hundred dollars a month. According to GoodRx, the average out‑of‑pocket cost for Briviact is about $1,200–$1,500 a month when a generic or a tiered formulary is applied. Those figures vary with the specific insurance plan and whether the patient is on a high‑deductible health plan.[2]

Can a patient get help from a manufacturer program?
Yes. Janssen (the maker of Briviact) offers a patient assistance program that covers the cost for qualifying patients who cannot afford the drug. Eligibility is determined by income and insurance status, and the program requires an application through the company’s website.[3]

How does Briviact’s price compare to other seizure‑control drugs?
Typical brand‑name antiepileptics such as Keppra or Trobic cost between $1,000 and $1,700 per month. Even newer agents like Levetiracetam and Lamictal fall in that range. Briviact is therefore more than ten times the list price of many comparable drugs, largely because it targets a rare condition—status epilepticus and refractory seizures—and because no generic exists yet.[4]

What about pricing outside the U.S.?
In Canada, Briviact’s list price is roughly $1,800 per month, and in Australia the cost is about AUD 2,000 per month. Prices in other countries vary widely, often reflecting national health‑system negotiations and subsidy schemes. International pricing is typically lower than in the U.S., but still higher than many generic alternatives in those markets.[5]

When will the price change?
The drug’s exclusivity period expires in 2033, after which a generic entrant could lower the price. Until that time, list price is unlikely to shift, though manufacturer discounts or insurance negotiations could reduce out‑of‑pocket costs.
