NEW YORK (TheStreet) -- Amgen (AMGN) - Get Amgen Inc. Report, J&J (JNJ) - Get Johnson & Johnson Report unit Centocor Ortho Biotech, and affiliate companies are sending out recall letters for certain lots of Epogen and Procrit anemia drugs because they may contain thin glass flakes.
This, as J&J continues to wrestle with the effects of its massive medicine recalls.
In a statement, Amgen said the "extremely" thin glass flakes result from the interaction of the formulation with glass vials over the shelf life of the product.
The company said the glass flakes are "barely visible in most cases" and that there have been no complaints or serious events reported in relation to the glass flakes.
"Evaluations by Amgen and Centocor Ortho Biotech ... found a low potential to impact patients who may have received the affected product," the statement said.
Epogen and Procrit are manufactured in the U.S. by Amgen. Epogen is sold by Amgen in the U.S. and Centocor Ortho Biotech is the authorized distributor of Procrit in the country.
"Amgen and Centocor Ortho Biotech Products and their affiliate companies have initiated recall letters and other communication to immediately inform relevant stakeholders, including healthcare professionals, distributors, wholesalers and pharmacies of the voluntary recall," the statement said.
Shares of J&J are up 0.2% to $61.96 in Friday afternoon trading, while Amgen stock is up 0.3% to $55.86.
