Educate patients about proper disposal of unused Rx medications—for their safety

Patients often tell clinicians that they used their “left-over” medica­tions from previous refills, or that a family member shared medication with them. Other patients, who are non-adherent or have had a recent medication change, might reveal that they have some unused pills at home. As clinicians, what does this practice by our patients mean for us?

Prescription drug abuse is an emerg­ing crisis, and drug diversion is a signifi­cant contributing factor.1 According to the Substance Abuse and Mental Health Services Administration’s National Survey on Drug Use and Health,2 in 2011 and 2012, on average, more than one-half of partici­pants age ≥12 who used a pain reliever, tranquilizer, stimulant, or sedative non-medically obtained their most recently used drug “from a friend or relative for free.”

Unused, expired, and “extra” medi­cations pose a significant risk for diver­sion, abuse, and accidental overdose.3 According to the Prescription Drug Abuse Prevention Plan,1 proper medica­tion disposal is a major problem that needs action to help reduce prescription drug abuse.

Regrettably, <20% of patients receive advice on medication disposal from their health care provider,4 even though clini­cians have an opportunity to educate patients and their caregivers on appro­priate use, and safe disposal of, medica­tions—in particular, controlled substances.

What should we emphasize to our patients about disposing of medications when it’s necessary?


Teach responsible use

Stress that medications prescribed for the patient are for his (her) use alone and should not be shared with friends or family. Sharing might seem kind and generous, but it can be dangerous. Medications should be used only at the prescribed dosage and frequency and for the rec­ommended duration. If the medication causes an adverse effect or other problem, instruct the patient to talk to you before making any changes to the established regimen.


Emphasize safe disposal

Follow instructions.
The label on medi­cation bottles or other containers often has specific instructions on how to prop­erly store, and even dispose of, the drug. Advise your patient to follow instructions on the label carefully.

Participate in a take-back program. The U.S. Drug Enforcement Administration (DEA) sponsors several kinds of drug take-back programs, including permanent locations where unused prescriptions are collected; 1-day events; and mail-in/ship-back programs.

The National Prescription Drug Take-Back Initiative is one such program that collects unused or expired medications on “Take Back Days.” On such days, DEA-coordinated collection sites nationwide accept unneeded pills, including pre­scription painkillers and other controlled substances, for disposal only when law enforcement personnel are present. In 2014, this program collected 780,158 lb of prescribed controlled medications.5

Patients can get more information about these programs by contacting a local phar­macy or their household trash and recycling service division.1,6

Discard medications properly in trash. An acceptable household strategy for disposing of prescription drugs is to mix the medication with an undesirable substance, such as used cat litter or coffee grounds, place the mixture in a sealed plastic bag or disposable container with a lid, and then place it in the trash.

Don’t flush. People sometimes flush unused medications down the toilet or drain. The current recommendation is against flush­ing unless instructions on the bottle specifi­cally say to do so. Flushing is appropriate for disposing of some medications such as opiates, thereby minimizing the risk of acci­dental overdose or misuse.6 It is important to remember that most municipal sewage treatment plans do not have the ability to extract pharmaceuticals from wastewater.7

Discard empty bottles. It is important to discard pill bottles once they are empty and to remove any identifiable personal infor­mation from the label. Educate patients not to use empty pill bottles to store or trans­port other medications; this practice might result in accidental ingestion of the wrong medication or dose.These methods of disposal are in accordance with federal, state, and local regulations, as well as human and environ­mental safety standards. Appropriate dis­posal decreases contamination of soil and bodies of water with active pharmaceutical ingredients, thereby minimizing people’s and aquatic animals’ chronic exposure to low levels of drugs.3

Encourage patients to seek drug safety information. Patients might benefit from the information and services pro­vided by:
• National Council on Patient Information and Education (www.talkaboutrx.org)
• Medication Use Safety Training for Seniors (www.mustforseniors.org), a nationwide initiative to promote medi­cation education and safety in the geri­atric population through an interactive program.

Remember: Although prescribing medi­cations is strictly regulated, particularly for controlled substances, those regulations do little to prevent diversion of medications after they’ve been prescribed. Educating patients and their caregivers about safe dis­posal can help protect them, their family, and others.
