While there are many causes of Maryland pharmacy errors, one of the most frequently reported errors involves a patient receiving the wrong medication from their pharmacist. In many cases, the pharmacist provides a patient with a drug that has a name similar to the drug which they were prescribed.
The Institute for Safe Medication Practices (ISMP) has coined the term look-alike sound-alike (LASA) drug to describe a medication that is either spelled or pronounced similar to other medications. It is estimated that up to 35% of all medication errors involve LASA medications. The IMSP has also published a list of the most common LASA drugs.
For example, common LASA drugs include:
- hydromorphone and morphine
- vinblastine and vincristine
- tramadol and trazodone
