In 2008, ERS saw an estimated 1 million visits from people abusing prescription or over-the-counter medicines mostly painkillers and sedatives. That was about the same number of visits from those overdosing on heroin, cocaine and other illegal drugs, according to a government report released Thursday.
Only five years earlier, illegal drug visits outnumbered those from legal medications by a 2-to-1 margin.
In other words, the number of ER visits from medication abuse doubled, said Peter Delany of the Substance Abuse and Mental Health Services Administration.
"It's a pretty startling jump," Delany said. He led a team that worked with the Centers for Disease Control and Prevention on the report.
Painkillers and sedatives clearly drove the trend. ER visits for the painkillers oxycodone and hydrocodone more than doubled from 2004 to 2008. And cases from one kind of tranquilizer nearly doubled.
The estimates are based on emergency room data from more than 200 U.S. hospitals. Many of the cases may be overdoses, but some may come from mixing drugs or combining them with alcohol, Delany said.
