Pharmacy and medication errors are not limited to similar looking pills getting mixed up. A recent article by a pharmacist discusses the value of having an independent verification process in place in order to prevent mix ups or misinterpretations.
For example, in one case an order for the drug “eribulin” was misinterpreted by a pharmacist and entered into the computer system as epirubicin, perhaps because of the similar spellings of the words. Fortunately in that case, a nurse discovered the error when she compared the prescription label with the original order, and as a result the patient did not receive the incorrect medication. Both of the drugs in that case are used in breast cancer treatment, which is another possible explanation for the pharmacist’s misinterpretation.
It is recommended that when the names of drugs are so similar, that hospitals and pharmacies have preventative measures in place to avoid look alike or sound alike mixups. For example, in the hospital where the mixup occurred, the hospital added additional terms to the names, and incorporated caps in the middle of the names to offset any potential misreadings. Additionally, an organization for drug safety has recommendations regarding how to list these medications to avoid other potential misreadings.
