Tbo-filgrastim Injection

What This Tbo-filgrastim Shortage Record Means

The FDA Drug Shortages database lists this record for Tbo-filgrastim Injection (brand: GRANIX) from Teva Pharmaceuticals USA, Inc. with a current status of To Be Discontinued. The affected dosage form is Injection, presented as Granix, Injection, 480 ug/1.6 mL (NDC 63459-920-59). Shortages are tracked at the manufacturer and presentation level — other manufacturers or formulations of the same generic may remain available, which is why pharmacists often can source a working substitute even when one record is flagged.

This shortage was first reported on Jun 13, 2025 and was last updated Jun 13, 2025. FDA-supplied reason codes are not recorded for this entry; common drivers include manufacturing quality issues, raw-material constraints, demand surges, and voluntary business decisions to discontinue a presentation. No other current shortage records match this generic in the database, which can signal that either the disruption is contained to one manufacturer or other suppliers have not yet formally reported a shortfall.

A shortage listing is a supply-side signal, not a patient-level instruction. Access can vary dramatically by pharmacy, region, hospital system, and insurance formulary — local pharmacists have real-time visibility that a national database cannot provide. Therapeutic substitutes often exist in the same class, but switching decisions belong with your prescriber, who weighs efficacy, dosing conversion, interaction profile, and personal history.
