FDA Shortage Status
Whether any manufacturer currently reports this drug as in shortage on the FDA Drug Shortages database. "Active Shortage" means at least one presentation has status "current."
No Shortage
Shortage History
Each row is a separate manufacturer's FDA shortage filing — not a timeline for the drug as a whole. Multiple "current" entries are normal: each manufacturer/NDC files independently. Status reflects the manufacturer's report; reason describes their supply situation (Available, Unavailable, or to be discontinued).
