ⓘ How this was built
Data sources
- CMS NADAC weekly survey + monthly archives back to 2013 (data.medicaid.gov)
- CMS Federal Upper Limit files (weighted AMP)
- FDA NDC Directory (openFDA) — maker roster
Method
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.

Common questions
- Is Liothyronine sodium in shortage right now?
- No. FDA does not currently list Liothyronine sodium in shortage. This page is rebuilt every morning from FDA's shortage database, so a new posting appears here the day it is published.
- Who makes Liothyronine sodium?
- 25 companies have marketed Liothyronine sodium in the last 30 days, according to the FDA NDC Directory. Every manufacturer and package is listed on this page.
- What does Liothyronine sodium cost?
- The typical pharmacy pays about $0.3217 per unit, based on the most recent CMS NADAC survey of actual acquisition costs. That is what the pharmacy pays for the drug itself — not the cash price, and not what an insurer is billed.
