Overview
A drug recall is a voluntary or FDA-requested action taken by a manufacturer to remove a medication from the market, or to correct it, because it does not meet safety, quality, or labeling standards. Recalls are one of the primary tools the FDA and drug manufacturers use to protect patients once a problem is discovered after a product has already reached pharmacies and consumers.
This specific drug recall involving BUSULFAN is classified as Class III, and was reported on May 27, 2026 by Sagent Pharmaceuticals.
The sections below explain, in plain language, what is known about this drug recall, who it may affect, and what steps patients and caregivers can reasonably take.

What Happened
Sagent Pharmaceuticals initiated action on BUSULFAN on May 27, 2026 after identifying a product quality or potency issue. The action affects specific lots or units of this medication rather than every unit ever produced, so not every package on the market is necessarily involved.
The action is described in FDA records as voluntary: firm initiated, and its current status in FDA records is listed as "Ongoing". Recall status can change as the firm works through correction or removal, so the most current information is always the official FDA recall record linked below.
