Though making drugs may take a bit of science, naming them is takes a bit of an art. The problem is that many of these artists seem a bit derivative. Nearly 1,500 commonly used drugs are involved in errors because they sound like other drugs or their names look like the names of other drugs, according to The 8^th Annual National MEDMARX Data Report from U.S. Pharmacopeia, a private, non-profit, standards-setting organization. The organization’s MEDMARX is an anonymous, Internet-accessible program used by hospitals and other institutions nationwide to report, track, and analyze medication errors. The report, which was based on 26,000 records submitted to the database from 2003 to 2006, found each of the top ten most prescribed drugs in America are commonly confused with at least one other drug. A total of 1.4 percent of all errors resulted in patient harm, including seven errors that may have caused or contributed to patient deaths. The authors of the report said they believe the number of adverse events from drugs that sound-alike or look alike is understated because of widespread underreporting. The group wants prescribers and pharmacists to include an “indication for use” on prescriptions as a way to prevent errors. Below is a list of the drugs with the most look-alike/sound-alike pairs.
