New Anticoagulant Requires Proper StorageAschenbrenner, Diane S. MS, RNAJN The American Journal of Nursing: July 2011 - Volume 111 - Issue 7 - p 26 doi: 10.1097/01.NAJ.0000399311.90784.54 Drug Watch Abstract Author Information Exposure of the new anticoagulant dabigatran (Pradaxa) to atmospheric moisture may contribute to deterioration of the drug and a loss of efficacy. Exactly how much efficacy can be lost isn't clear. Dabigatran should be stored in its original container, away from moisture, heat, and excessive cold; bottles of dabigatran should be used within 30 days of opening. Diane S.
