Details on approvals, recalls, warnings and more.


Recalls, warnings, label changes

A revision to the label of drospirenone-containing contraceptives (Beyaz and Yasmin) noting that some epidemiologic studies reported as high as a threefold increase in the risk of blood clots for these pills compared to products containing levonorgestrel or some other progestins, whereas other epidemiological studies found no additional risk of blood clots. The FDA recommends that clinicians consider the risks and benefits of drospirenone-containing birth control pills and a woman's risk for developing a blood clot before prescribing.

A recall of two lots of cyanocobalamin injection, USP, 100-mcg/mL, 1-mL vial, produced by American Regent, due to cracks in the vials. No adverse events have been reported but loss of sterility could result in systemic infection, abscess formation, or infection at the injection site.

A warning about a counterfeit version of bevacizumab (Altuzan) 400 mg/16 mL. The FDA warns that the drug was purchased by U.S. medical practices from foreign sources and was found to contain no active ingredient. In addition, the drug has not been approved for use by the agency.

A recall of argatroban injection, 50 mg per 50 mL due to a potential for visible particulates. No adverse events have been reported but visible particulates pose a risk of embolization/infarction to organs with potential organ complications.

A warning and dosing clarification for the antidepressant citalopram hydrobromide (Celexa and generic forms) regarding the risk of QT prolongation and torsade de pointes. In August 2011, the FDA advised that citalopram should no longer be used at doses greater than 40 mg per day. Now the maximum recommended dose for patients older than 60 years of age is 20 mg per day. The label has also changed regarding patients with congenital long QT syndrome, in whom use of the drug is now “not recommended” instead of “contraindicated” because some patients with the condition could benefit from a low dose of citalopram and lack viable alternatives.

A class I recall of the Acclarent Inspira AIR balloon dilation system because of potential for the balloon to not deflate or deflate slowly. Four reports of incidents, one resulting in patient injury, have been reported

A recall of all sterile products from Franck's Compounding Pharmacy of Ocala, Fla., due to the possibility of lack of sterility. Infections were reported in patients receiving drugs from the pharmacy during eye surgery.”

A class I recall of Thoratec Corporation's HeartMate II Left Ventricular Assist System because detachment of the bend relief from its intended position around the proximal outflow graft may allow the graft to kink or deform, resulting in reduction of blood flow and potentially serious adverse health consequences, including death.
