Sodium Thiosulfate Injections recalled

American Regent is conducting a nationwide voluntary recall to the consumer and user level of the following product:

PLEASE NOTE:  This recall, initiated on February 2, 2011 to the User or Consumer Level, is for lot # 0056 Only. No other lots or sizes of Sodium Thiosulfate Injection, USP are subject to this voluntary recall.

This voluntary recall was initiated because some vials of this lot exhibit translucent visible particles consistent with glass delamination.  Glass delamination can occur with high pH solutions when the surface glass from the vial separates into thin layers, resulting in glass particles with a flaky appearance.

Sodium Thiosulfate Injection, USP is indicated in the treatment of cyanide poisoning.
