Medication Disposal Challenges in LTC
The disposal of unused and expired medications creates a significant issue in long term care facilities (LTCFs), with patients reported to receive, on average, eight scheduled (routine) medications and an additional three PRN (as needed) medications.1 The number of medications that go unused by the nearly 1.4 million skilled nursing patients in the United States alone results in about 1.5 million pounds of medication waste each year.2
The improper disposal of these medications led in part to the detection of these pharmaceuticals in waterways and eventually in the water supply. A 2002 US Geological Survey Study confirmed that pharmaceutical compounds were detected in 80% of the 139 streams sampled.3 The Environmental Protection Agency (EPA) released a 2008 study on unused pharmaceuticals in the health care industry that discussed the management and disposal of unused pharmaceuticals and the presence of pharmaceuticals in the water supply. The EPA report noted that these medications enter the water supply through direct excretion or improper disposal by patients themselves and improper disposal by health care facilities that have improperly flushed pharmaceuticals, placed medications in "red bag" regulated medical waste, or just thrown them into the trash.2
Reasons for Unused Medications
• a resident's medical condition has been resolved before the medication is completely consumed;
• a resident has an adverse effect from the medication and must discontinue therapy;
• a resident is transferred to a hospital and it is unclear whether he or she will return to the facility;
• the medication is ineffective and the physician modifies the resident's medication;
• a resident fails to adhere to the therapy prescribed;
• a resident dies, leaving behind a supply of medications; or
• medications are not completely used before their expiration date is reached.
Consequences of Inappropriate Medication Disposal
• increased potential for accidental poisoning;
• unintended overdoses;
• prescription drug diversion;
• possible environmental contamination;
• disruption to facility operations due to extended external investigations;
• negative public relations within the community;
• regulatory citations, penalties, and fines; and
• potentially costly cleanup efforts.
CMS and FDA
However, medication disposal in LTCFs is complex and often confusing due to the competing objectives from multiple regulatory agencies that have taken steps to address pharmaceutical waste. Despite good intentions, the recommendations or regulations from these agencies have typically been uncoordinated and are often in conflict with one another, thereby increasing the potential for noncompliance.
The FDA website page "Disposal of Unused Medicines: What You Should Know," provides guidance to consumers and LTCFs in certain cases on the disposal of medications through take-back programs or Drug Enforcement Administration (DEA)-authorized collectors.4
Flushing of Certain Medicines
In particular, the FDA recommends that used fentanyl patches be disposed of by folding together the adhesive side of the patch and then flushing it down the toilet to reduce the risk of accidental exposure, ingestion, or overdose, particularly by children. Fentanyl patches, marketed under the brand name Duragesic, are a focus of the FDA's Safe Use Initiative, an ongoing effort to educate consumers and health care professionals and reduce preventable medication harm.5 In a November 2012 memo, CMS also provided additional guidance to nursing home surveyors around fentanyl patch disposal.6
It should be noted that the recommendation to flush medications or dispose of them down the drain is prohibited in some states or local municipalities. It is recommended to consult local wastewater treatment plants to determine what pharmaceutical wastes are appropriate to dispose of via the sewer system in health care facilities. In general, this practice should be avoided if at all possible in LTCFs.7
White House Office of National Drug Control Policy
• Do not flush prescription drugs down the toilet or drain unless the label or accompanying patient information specifically instructs you to do so.
• If a drug take-back or collection program is not available, use the following disposal method:
1. Take prescription drugs out of their original containers.
2. Mix drugs with an undesirable substance, such as cat litter or used coffee grounds.
3. Put this mixture into a disposable container with a lid, such as an empty margarine tub, or a sealable bag.
4. Conceal or remove any personal information from Rx containers.
5. Place the sealed container with the mixture and the empty drug containers in the trash.

Key Points of the Disposal Act
• LTCFs may dispose of pharmaceutical controlled substances by depositing them into an authorized collection receptacle.
• In LTCFs, an authorized retail pharmacy or hospital/clinic with an on-site pharmacy may install, manage, and maintain a collection receptacle.
• Controlled substances and noncontrolled substances may be placed into receptacles.
• Controlled substances disposed of by transferring into a collection receptacle should occur immediately, or not longer than three business days after discontinuation.
• Discontinuation of use includes a permanent discontinuation as directed by the prescriber, as a result of the resident's transfer from the LTCF, or upon death of the resident.
• One supervisor-level employee of the LTCF (eg, charge nurse) designated by the authorized collector may assist in changing the collection receptacle inner liner, provided it is done under the supervision of one employee of the authorized collector.
• Upon removal, sealed inner liners may be stored at the LTCF for up to three business days in a securely locked, substantially constructed cabinet or a secured room with controlled access.
• Controlled substances transferred from ultimate users to authorized collectors via either collection receptacles or mail-back programs must be securely stored or transferred until rendered nonretrievable.8
The EPA proposal's revised regulations are intended to improve the management and disposal of hazardous waste pharmaceuticals and to address specific issues health care facilities face related to the management of unused/expired pharmaceuticals.
All health care facilities are subject to the EPA rule as proposed. The term "health care facility" is broadly defined and includes LTCFs. The EPA defines these LTCFs as licensed entities "that provide assistance with activities of daily living, including managing and administering pharmaceuticals to one or more individuals at the facility."9
Per EPA definition, LTCFs include but are not limited to assisted living facilities, hospices, nursing homes, skilled nursing facilities, and the assisted living and skilled nursing care portions of continuing care retirement communities (CCRCs). Note that group homes, independent living communities, and independent living portions of CCRCs are not included.9
Hazardous Waste Pharmaceuticals

Treatment of Hazardous Waste Pharmaceutical Residue
• Unit-dose containers including medication packets, pill cups, blister packs, bottles, and vials holding up to one liter of liquid or 1,000 pills will be considered RCRA empty if the pharmaceuticals have been fully dispensed.
• Syringes that held hazardous waste pharmaceuticals are also medical waste. Currently, these dual wastes must be managed to be in compliance with both RCRA and medical waste regulations. The EPA proposes to exclude syringes that contain residue of hazardous waste pharmaceuticals and instead, dispensed syringes can be disposed of as medical waste.
The EPA proposes to regulate other containers with residue of hazardous waste pharmaceuticals (eg, IV bags and tubing, inhalers, aerosols, and medicine tubes) as hazardous waste if the residues contain listed hazardous wastes or exhibit a hazardous waste characteristic. In determining whether a pharmaceutical is a characteristic hazardous waste, the dose form is considered; for example, if in alcohol, then the drug is likely ignitable under EPA procedures, and therefore hazardous.9
• Health care facilities must inform employees who handle hazardous waste pharmaceuticals regarding the proper handling and disposal of these wastes. Training can be administered verbally or through written materials.
• Instead of assigning containers for hazardous waste pharmaceuticals' specific waste codes, the EPA proposes to eliminate this requirement and instead allow health care facilities to simply mark containers "hazardous waste pharmaceuticals."
• The EPA proposes allowing health care facilities to accumulate hazardous waste pharmaceuticals for up to one year before they must be shipped to a disposal facility.9
