Warning on Warfarin Monitoring

JAMA. 2018;320(21):2193. doi:10.1001/jama.2018.18789

The FDA expected patients and physicians who use at-home or in-the-office medical devices that monitor warfarin levels to have accurate test strips by late November after a Class I recall, the most serious type.

Roche Diagnostics voluntarily recalled more than 1.1 million packages of its CoaguChek XS PT Test Strips that were distributed nationally between January 12 and October 29. “Using faulty strips can lead to serious errors in medication dosage that could cause serious harm or death in some patients,” Jeffrey Shuren, MD, director of the FDA’s Center for Devices and Radiological Health, said in a statement.
