While hospitalized, a 68-year-old man was prescribed the anticoagulant, enoxaparin, to treat deep vein thrombosis. However, the medical staff mistakenly prescribed two identical prescriptions for enoxaparin, thus doubling the daily dose the patient would have received. MedAware alerted the staff, and one of the medications was canceled before administration.

If given a double dose of enoxaparin, the patient could have suffered major internal bleeding.
