Coumadin (warfarin sodium) Crystalline 5 mg Tablets: Recall - Tablets May Have Higher than Expected Potency
AUDIENCE: Cardiology, Pharmacy, Patients
ISSUE: Bristol-Myers Squibb initiated a voluntary recall of one lot of 1,000-count bottles of Coumadin (warfarin sodium) Crystalline 5 mg tablets. Company testing of tablets from a returned bottle found a tablet to be higher in potency than expected. The lot number affected in the U.S. is 9H49374A with an expiry date of September 30, 2012. A decrease of active ingredient may increase the risk of clots which could lead to heart attack or stroke, and if there is too much active ingredient, there is an increased risk of bleeding.
BACKGROUND: Coumadin is prescribed to treat or prevent blood clots.
RECOMMENDATION: Patients who may have 5 mg tablets should not interrupt their therapy but should seek advice from their pharmacist to see if they have tablets originating from the affected lot and if so, should consult their physician for appropriate medical advice.
