Bristol-Myers Recalls Popular Blood Thinner

Bristol-Myers Squibb Co. says it is recalling one production lot of its blood thinner Coumadin after finding an oversize tablet.

The company says it tested a returned bottle of Coumadin and found that one tablet was more potent than expected. An excessive dose of Coumadin, or warfarin, could create an increased risk of bleeding. The recall affects 5-milligram Coumadin tablets with an expiration date of Sept. 30, 2012. The production lot is number 9H49374A.

The New York drugmaker says patients taking 5-milligram tablets should not stop taking them, but should talk to their pharmacist to find out if their prescription was filled with tablets that have been recalled.
