Using trade names: a risk factor for accidental drug overdose

Arch Intern Med. 2002 May 13;162(9):1065-6. doi: 10.1001/archinte.162.9.1065.


Medication errors due to the exclusive use of trade names of drugs may lead to life-threatening complications. We report the case of a patient with verapamil overdose as a result of this. This case illustrates that the use of trade names, omitting the international nonproprietary names of the active moiety, carries the risk of serious adverse drug events by overdose.
