FDA Class I recall: an injectable out of specification for bacterial endotoxin — the pyrogen that survives killing the bacteria (Victory Medical Center Pharmacy)

1Endotoxin survives killing the bacteria

Bacterial endotoxin is a component of the outer cell wall of Gram-negative bacteria, a lipopolysaccharide. Its defining property is that it persists after the organism itself is dead. Heat and sterilization can kill the bacteria, but endotoxin is heat-stable and can remain in the product.

For that reason, injectables are tested for endotoxin separately from any test of sterility. Endotoxin reaching the bloodstream provokes fever and an inflammatory response, and in sufficient quantity can lead to a severe systemic reaction. That this recall is stated as microbial contamination of a sterile product while the concrete failure is an out-of-specification endotoxin result reflects exactly that two-part control.

2The multi-dose vial format

The MDV in the product name stands for multi-dose vial — a vial designed for repeated withdrawals from a single container. The benzyl alcohol 1.5% in the recorded formulation is an ingredient commonly used as a preservative, so that organisms do not grow as the stopper is punctured again and again.

A preservative, however, is meant to suppress the growth of organisms introduced later; it does nothing about endotoxin already present at the time of manufacture. And the multi-dose format means a fault in one vial can extend across several administrations.

391 units, distributed nationwide

The quantity is 91 units, and the party conducting the recall is a pharmacy rather than a pharmaceutical manufacturer. The formulation on the record is a specific mixture of several ingredients, which is the form of an injectable prepared at a facility rather than a ready-made approved product. Small as the quantity is, distribution reached across the country.

4Seventeen records cite endotoxin

Of the 1,408 FDA recall records this site holds as of 2026-09-01, 17 name endotoxin in the reason for recall.

Against the many records that turn on sterility itself, few cite the quantity of a pyrogen. The absence of organisms and the absence of what organisms left behind are separate requirements, and the second is only visible once it is measured. The small count reflects a failure that cannot be seen without testing, not a rare problem.
