What is “Arcalyst package 4”?
“Arcalyst” is the brand name for rilonacept, an injectable medicine used for certain inflammatory conditions. “Package 4” usually refers to a specific commercial package size/configuration (for example, a particular vial count or dosing format), which can affect the price per package and the way it’s billed.
Which exact NDC/package corresponds to “package 4”?
Package numbers vary by:
- the NDC (National Drug Code) assigned to that specific package configuration,
- the manufacturer labeler/strength, and
- the country/market.
To identify “package 4” precisely, you typically need the NDC shown on the listing or prescription/dispensing record. If you share the NDC number (or a screenshot/text of the package details), I can help pin down the exact package and what it contains.
Why does the package number matter for cost?
Different package configurations can lead to different:
- Wholesale/retail pricing and reimbursement amounts,
- patient out-of-pocket cost (copay/coinsurance depends on the billed package),
- remaining supply and dosing schedule.
