Several law enforcement agencies and pharmacies in Iowa are taking part in the National Prescription Drug Take Back Day on Saturday (April 29, 2017).

Hours of the event are 10 a.m. to 2 p.m. at various locations. The list of area drop-off sites is posted below.

Sponsored by the Drug Enforcement Administration (DEA), Drug Take Back Day lets patients and their families dispose of unwanted, unused or expired medications. The service is free and anonymous, no questions asked.

Illicit substances such as marijuana are not part of this initiative. Injectable, IV solutions, inhalers and other compressed air cylinders will not be accepted.

The Take Back event addresses a vital public safety and public health issue. According to DEA, medicines that languish in home cabinets are highly susceptible to diversion, misuse, and abuse. Rates of prescription drug abuse in the U.S. are alarmingly high, as are the number of accidental poisonings and overdoses due to these drugs.

Studies show that a majority of abused prescription drugs are obtained from family and friends, including from the home medicine cabinet. In addition, Americans are now advised that their usual methods for disposing of unused medicines—flushing them down the toilet or throwing them in the trash—both pose potential safety and health hazards.

Last October, Americans turned in 366 tons (over 730,000 pounds) of prescription drugs at almost 5,200 sites operated by the DEA and more than 4,000 of its state and local law enforcement partners. Overall, in its 12 previous Take Back events, DEA and its partners have taken in over 7.1 million pounds—more than 3,500 tons—of pills.
