the University of California at San Francisco surveyed nearly 900 California pharmacies by phone over a two-month period in 2018 during the week and on weekends. For the study, published Monday in the journal
Annals of Internal Medicine, researchers posed as parents with leftover opioids and antibiotics from a child’s surgery.
US Food and Drug Administration guidelines.
The agency recommends taking unused medications to drug disposal or takeback programs as the best way of getting rid of unused or unwanted drugs. If a disposal program is not available, the agency suggests mixing antibiotics with coffee grinds or kitty litter, sealing the mixture in a container and throwing it in the garbage. It recommends flushing opioids.
Researchers found only 47% of pharmacies gave correct instructions on how to dispose of antibiotics and 34% provided correct information about opioid disposal. On weekends, only 15% correctly directed customers about safe antibiotic disposal and 7% gave the correct information about disposing of opioids.
When asked about takeback programs at the 898 pharmacies, 91 said they had a program for antibiotic disposal and 82 said they had a program for opioid disposal.
“This clearly points to the need for better dissemination of information on proper medication disposal,” Hillary Copp, senior study author and associate professor of urology at UCSF, said in a statement.
FDA has specific instructions on how to dispose of these medications, and the American Pharmacists Association has adopted this as their standard. Yet it’s not being given to the consumer correctly the majority of the time,” Copp said.
The improper disposal of medication can result in antibiotic resistance, pollution, child and pet poisonings and drug misuse.
