Diabetes Disaster Averted #55: Medication Mix-up

Oct 16, 2011

An elderly patient noticed that his usually good control with a 70/30 insulin pen had diminished recently, and stopped by our diabetes education program to ask for help….

He showed me his current pen. It was NPH only, from the same manufacturer. The patient had been getting samples from his equally elderly doctor, and neither noticed that he had the wrong medication. The pens looked the same, and the label used relatively small type, too small for their vision. As soon as he got the correct medication, his control returned to its previous success. This underscores the importance of looking at the actual medicine containers.

I’ve also discovered a patient taking both Glucophage and Metformin, not realizing they were the same. He was taking more than the maximum dose.

Lesson Learned:

It is crucial that patients know what medications they are using and their mechanism of action. They need to be responsible for knowing both the brand names and the generic name. If they notice anything different, they should ask questions.
