Common questions
- Is Azathioprine in shortage right now?
- No. FDA does not currently list Azathioprine 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 Azathioprine?
- 28 companies have marketed Azathioprine in the last 30 days, according to the FDA NDC Directory. Every manufacturer and package is listed on this page.
- What does Azathioprine cost?
- The typical pharmacy pays about $0.1249 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.
