Americans filling fewer opioid prescriptions

The number of prescriptions for opioid painkillers filled in the U.S. fell dramatically last year, showing their biggest drop in 25 years and continuing a decline amid increasing legal restrictions and public awareness of the dangers of addiction, new data show.

Health data firm IQVIA’s Institute for Human Data Science released a report Thursday showing an 8.9 percent average drop nationwide in the number of prescriptions for opioids filled by retail and mail-order pharmacies. All 50 states and the District of Columbia had declines of more than 5 percent. Declines topped 10 percent in 18 states, including all of New England and other states hit hard by the opioid overdose epidemic, such as West Virginia and Pennsylvania.

“We’re at a really critical moment in the country when everybody’s paying attention to this issue,” said Michael Kleinrock, the institute’s research director. “People really don’t want them if they can avoid them.”

There was an even greater drop in total dosage of opioid prescriptions filled in 2017, down 12 percent from 2016. Reasons for that include more prescriptions being for a shorter duration, a 7.8 percent decline in new patients starting on opioid prescriptions and far fewer high-dose prescriptions.

Opioid doses are measured in “morphine milligram equivalents.”

(A standard Vicodin pill has the equivalent of 5 milligrams of morphine.) Prescriptions for dosages of 90 morphine milligram equivalents per day or more, which carry the highest addiction risk, declined by 16 percent last year, according to the report.

The U.S. is estimated to consume roughly 30 percent of all opioids used worldwide.

Opioid prescriptions and daily doses rose steadily starting in the 1990s, fueled by factors including marketing of new opioid pills such as Oxycontin. Use peaked in 2011 at levels far above those in other wealthy countries where national health systems control narcotics more aggressively.

The U.S. decline began after overdoses and deaths from prescription opioids and illicit narcotics soared, and multiple groups pushed back.
