Busulfan Injection

What This Busulfan Shortage Record Means

The FDA Drug Shortages database lists this record for Busulfan Injection (brand: BUSULFAN) from Mylan Institutional, a Viatris Company with a current status of To Be Discontinued. The affected dosage form is Injection, presented as Busulfan, Injection, 6 mg/1 mL (NDC 67457-893-08). 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 Oct 24, 2025 and was last updated Oct 24, 2025. The FDA cites the following reason: Discontinuation of the manufacture of the drug. 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.
