While hospitalized, a 56-year-old woman was supposed to receive Zaroxolyn (metolazone), a diuretic for treatment of her pulmonary edema. Instead, she was mistakenly prescribed the antiseizure medication, Zarontin (ethosuximide). MedAware alerted to the error, and the order was canceled.

If given the wrong medication, the patient could have suffered from the drug’s side effects, such as behavioral changes and low white blood cells.
