Most People Keep Their Leftover Rx Opioids

"Who Is Keeping Their Unused Opioids and Why?"

That’s an important question, especially since we're currently in the midst of a drug crisis. The last thing we want is more prescription drugs being diverted onto the street and circulated for non-medical use. The issue was the subject of a research article published last year in Pain Medicine.

The authors surveyed 235 patients who received hydrocodone prescriptions following emergency room visits between July 2015 and August 2017. All were given information about how to safely dispose of their unused hydrocodone. Researchers contacted the patients a month after they were discharged, asking what they planned on doing with their leftover pills. 

Over half said they had no intention of giving them up. Only 100 of the 235 said they would follow advice and dispose of their unused medication.  

When asked why they were keeping their leftover pills, patients said it was “in case I have pain,” “just in case” and “You never know. If I need it [when I'm traveling out of the country], I can use it.”

A larger national study conducted in 2015 had similar findings. Over 60 percent of patients prescribed opioids said they planned on keeping their leftover pills for future use.

Policy Changes May Be Making the Problem Worse

Over the past several years, partly in an effort to decrease the number of unused opioids, there has been a sweeping change in attitudes and practices of dispensing opioids in emergency rooms. According to the CDC, rates of prescribing opioids in ERs decreased by a third from 2006 to 2017.  

Since patients now receive fewer opioids from the ER than in the past, they are likely to have fewer unused pills. However, paradoxically, that may create more incentive for them to hold onto the unused opioids in case they need them in the future.

It is not just emergency rooms that are providing patients with fewer opioids. Increasingly, patients discharged following surgeries receive less opioid medication or none at all, even though 80 percent of them feel their post-op pain was inadequately treated. 

Under-treated acute pain can cause permanent harm. In a recent issue of Anesthesiology, Editor-in-Chief Evan Kharasch, MD, and several of his colleagues penned an editorial, “Rational Perioperative Opioid Management in the Era of Opioid Crisis.”

They said there was little evidence to support the view that limiting opioids for post-operative pain was reducing abuse. Instead, it was leading to unintended consequences and “opioid phobia.” The authors specifically note that poorly controlled acute pain can lead to chronic pain.

People Worry Whether They Will Get Pain Medication

Many people clearly want to hold onto their unused medications. This is not new. However, the problem may worsen because, more than ever, patients fear that they will not be able to get opioid medication when they need it.

Keeping unused opioids is ill-advised for many reasons, the most important of which is that opioids should never be used except under the direction of a qualified provider. But there's another side to the story. If providers are going to refuse to treat pain, people will want to hold onto the medication they have been prescribed in order to avoid future suffering.

Of course, the intention of limiting the amount of opioids prescribed is to reduce the amount of drugs that could be diverted for non-medical use. But policies and practices designed to limit the amount of unused opioids may actually be dangerously creating a need to preserve, rather than dispose of, unused medication.

To paraphrase Dr. Kharasch, let us avoid making people in pain pay with unnecessary suffering for the opioid overprescribing sins of others.

Flushing Out the Truth About Disposing of Unused Pain Medication

By Dr. Lynn Webster, PNN Columnist

According to a 2016 survey, most Americans choose not to dispose of their leftover opioid pain medication because they want to keep it for potential future use. This is entirely understandable.

People have little incentive to dispose of their unused pain medication. It is expensive to replace drugs, and the person who owns the prescription has already paid for it. Also, a growing number of people are concerned that, should they someday need pain treatment, they will find it difficult to obtain opioid medication. They may even be accused of being a drug seeker if they ask for it.

So people don't necessarily have nefarious reasons for holding onto unused medication. However, leftover pain medication has been blamed for causing much of the opioid crisis because it can be easily diverted.

Leftover drugs can end up on the streets or in the wrong hands, such as family members or friends. In all cases, they can cause harm. Let's look at some numbers.

In 2013, nearly 9 billion pills containing hydrocodone were produced for prescription purposes. Other opioids added to the supply. Although this was several years ago and opioid production quotas have significantly reduced the supply of opioids, leftover pills are still a potential problem. Of those that are prescribed after surgery, more than 40% percent go unused.

Opioid drugs lose only about 1 percent of their potency per year. This means prescription opioids have a half-life of more than 50 years. These potent medications can remain viable (or toxic) for nearly a lifetime. 

At any given time, billions of opioid pills that still retain their potency are available for diversion and non-medical use. That is a problem.

Conflicting Information About Safe Disposal

A public education campaign may convince some people who are reluctant to give up their extra medication that it would be better for society if they get rid of the drugs. However, even if people were persuaded to dispose of their unused medication, they may not know how to do so safely.

A recent report by Time suggests that even pharmacists do not know how patients should dispose of their leftover drugs. Of 900 pharmacists surveyed, only 23 percent correctly told callers how to safely dispose of opioids according to FDA guidelines.

The pharmacists' confusion is understandable. Various authorities have delivered different messages over the years about the best way to dispose of unused drugs.

The FDA recognizes that there are environmental concerns about flushing medicines down the toilet. However, the agency also believes that the risks associated with narcotic medicine outweigh any potential risks associated with flushing. The FDA includes hydrocodone, oxycodone, methadone and other opioids on a lengthy list of medicines that should be flushed down a toilet if no other safe disposal options are available.

The FDA even recommends flushing unused fentanyl lozenges (ACTIQ). The disposal instructions are very complicated. They require both a pair of scissors and wire-cutting pliers, and are roughly as convoluted as Walter White's method of making crystal meth in television's "Breaking Bad." I suspect that not everyone who is prescribed ACTIQ would be willing or able to follow all of those steps.

Evidently, the FDA believes that the risk of harm from overdose is greater than the danger the drugs present to the environment and to our water supply. 

The Time story cites a 2017 U.S. Geological Survey and EPA report that found hundreds of drugs, including prescription opioids, in 38 streams across the country.

“Many of the drugs identified in the 2017 study are known to kill, harm the health of, or change the behavior of fish, insects and other wildlife. This, in turn, can impact the food chain, and eventually harm humans as well,” Time reported.

The FDA’s guidance on how to safely dispose of drugs can be confusing. Some medication is flushable, while other leftover drugs should be put in a sealed container or plastic bag with an “unappealing substance such as dirt, cat litter, or used coffee grounds” before being thrown out in the trash.

Take Back Programs

Drug take-back programs are intended to reduce the supply of excess prescription opioids and destroy the pills in an ecologically safe way. The FDA has a list of permanent take-back sites where people can dispose of unused medication. The DEA also has Drug Take Back Days, temporary collection sites for the safe disposal of prescription drugs.

However, not all take-back programs collect controlled substances. And it is estimated that fewer than 2 percent of unused drugs are returned. Also, these take-back programs are costly to implement.

The messaging around disposal of pain medication is conflicting. In a perfect world, all unused medication would be easily disposed of without causing negative consequences to the environment or the community. Also ideally, people in pain would not have to worry they might not receive a prescription for medication if they need one. Unfortunately, neither of those propositions is true.
