A familiar packaging snafu has led to another recall at Nichi-Iko Group's Sagent Pharmaceuticals. The Illinois-based manufacturer is recalling four lots of injectable levetiracetam, which is used to treat certain types of seizures, thanks to a "lack of container closure integrity" observed in reserve sample vials. The drug could become unsterile if the container it's stored in doesn't seal properly, Sagent explained in a recall announcement posted by the FDA Monday. Injecting a non-sterile product could cause serious and potentially fatal systemic infections, the company warned.
