Each month's band spans the NADAC unit prices of every NDC of this drug (min, quartiles, median, max), split into brand and generic cohorts by FDA marketing category. Maker counts come from distinct labelers with the NDC actively listed.
Pipeline and calculations built by Claude (Fable 5) from the public datasets above. Educational only — verify against primary sources before acting.
Every detected change for interferon beta-1a, newest first — price moves, shortages, recalls, and manufacturers entering or leaving. Detected by comparing each day’s federal data against the day before.
Other molecules FDA puts in Interferon beta, with whether each is in shortage right now. Same class is not the same drug — substitution is a clinical decision, and this is a supply picture, not a recommendation.
