Incorrect disposal of prescription drugs can contribute to antibiotic resistance, poisoning, water pollution and misuse.
But a new study in the journal Annals of Internal Medicine reports fewer than half of California pharmacies give proper guidance.
The U.S. Food and Drug Administration's guidelines for disposing of unused prescription drugs include mixing antibiotics with revolting trash, flushing opioids and using take-back programs.
But when researchers had secret shoppers contact California pharmacies during the week and ask what to do with their leftover prescriptions, only 49% gave correct guidance for antibiotics and only 20% offered proper information on opioid disposal.
On weekends, those numbers dropped to 15% and 7%, respectively.
Only 11% of the pharmacies reported having a program for antibiotic disposal. The same percentage said they offered an opioid disposal program.
Of 6,368 licensed pharmacies provided by the State of California Department of Consumer Affairs, 915 were sampled and 898 responded.
