Mrs. W is an 87 year old who was admitted to the CTU with pneumonia. She was treated with levofloxacin. Her past history was significant for CAD and atrial fibrillation for which she was taking metoprolol, warfarin and vasotec.
As she was confused, her medication list was determined by an older list her husband provided from their pharmacy. Included in that list was digoxin, a drug that was discontinued three months prior to the admission due to bradycardia.. The patient was on metoprolol 12.5 mg BID at home but it was ordered as 25 mg BID by mistake.
Due to increased dose of metoprolol and the inadvertently added digoxin, Mrs. W developed complete heart block from which she was successfully resuscitated.
She developed Upper GI bleed. At the time, her INR was found to be 9 which was likely secondary to a drug-drug interaction between coumadin and the new antibiotic levofloxacin for which she was again appropriately treated.
She was found to have a creatinine of 200 mmol/L and potassium of 5.4mmol/L. Despite this, her vasotec was not held and no repeat blood work was done until day 9 when she was found to have a creatinine of 650 mmol/L and potassium of 7.2mmol/L. She subsequently had to undergo dialysis.
