Methadone Poisoning Deaths, 1999-2004
From 1999 through 2006 the number of methadone-related deaths increased significantly. Most deaths are attributed to the abuse of methadone diverted from hospitals, pharmacies, practitioners, and pain management physicians. Some deaths result from misuse of legitimately prescribed methadone or methadone obtained from narcotic treatment programs, including use in combination with other drugs and/or alcohol. Methadone is a safe and effective drug when used as prescribed; however, when it is misused or abused--particularly in combination with other prescription drugs, illicit drugs, or alcohol--death or nonfatal overdose is likely to occur. This assessment analyzes increases in methadone diversion, abuse, and misuse that have occurred since 1999.
Methadone poisoning deaths increased 390 percent from 1999 through 2004 (the most recent data available; see Figure 1.) Additionally, selected state health department data indicate methadone poisoning deaths increased through 2006. The percentage increase in methadone deaths exceeds the percentage increase in "other opioid" (including oxycodone, morphine, hydromorphone, and hydrocodone) deaths during the same period. Other opioid deaths increased 90 percent during that time and accounted for a much larger percentage of total opioid-related deaths. Methadone deaths receive more media attention than do oxycodone- or hydrocodone-related deaths, very likely because of the drug's association with narcotic treatment programs (NTPs). A 2004 Substance Abuse and Mental Health Services Administration (SAMHSA) study reported that most methadone deaths involve abuse or misuse of methadone diverted in ways other than from NTPs and taken in combination with other drugs and/or alcohol.

Various methods are used to divert methadone. Wholesale-level quantities of methadone are stolen from delivery trucks and reverse distributors, and midlevel quantities are stolen from businesses such as hospitals and pharmacies. Retail-level quantities frequently are obtained through traditional prescription drug diversion methods such as doctor-shopping, prescription fraud and, to a much lesser extent, rogue Internet pharmacies. Methadone can be misused by patients being treated for chronic or cancer pain who obtain the drug using legitimate prescriptions. Following increases in OxyContin (oxycodone) addiction and death rates, many practitioners began using methadone to manage chronic pain and pain associated with cancer. Methadone is a safe and effective drug when used as prescribed; however, patients who are prescribed methadone need to be monitored by a physician well trained in the pharmacodynamic and pharmacokinetic properties of the drug, particularly if the patients have no prior history of opioid use for pain management.
Methadone has been used primarily in opioid addiction treatment for the past 50 years; however, its use in management of certain types of pain has steadily increased since the late 1990s. Methadone, a Schedule II Controlled Substance under the federal Controlled Substances Act, is a synthetic opioid that was first used in the United States in the late 1940s in the management of pain before becoming more widely used in opioid addiction treatment in the 1960s. Methadone suppresses withdrawal symptoms, reduces cravings for opioid drugs, and blocks the euphoric effects of opioids for 24 to 36 hours. In the late 1990s methadone became widely prescribed to treat acute and chronic pain because physicians sought an alternate analgesic to oxycodone (OxyContin) and hydrocodone (Vicodin), which were being increasingly diverted and abused. Additionally, methadone can be dosed less frequently, is less costly than most other opioid analgesics,3 and is a reasonable option for patients (particularly the elderly and those without prescription drug insurance coverage) who choose prescription drugs based on their ability to pay.
Methadone is effective in both opioid addiction treatment and pain management when used as prescribed; however, improper dosing or use in combination with other drugs and/or alcohol can be fatal. Methadone is dispensed from NTPs4 once daily because it is metabolized slowly and remains in the body for 24 to 36 hours. Opioid abusers seeking treatment enter NTPs with some level of opioid tolerance, lessening the likelihood of an overdose or poisoning death while in treatment. However, proper dosing during the initial stage of treatment, even among opioid-tolerant individuals, is critical to ensuring that an overdose does not occur. Additionally, any physician may prescribe methadone as an analgesic for management of pain, and when used properly, it is an effective pain reliever. Methadone is particularly useful for pain management patients (including those who develop a tolerance for other prescription opioids) whose pain does not decrease when they use other prescription opioids, for those who develop toxicity to other prescription opioids, and for those who cannot tolerate other prescription opioids. However, unlike some other opioid analgesics, methadone has a variable half-life and no sustained-release properties. Consequently, when methadone is used improperly (such as too frequently during the initial stages of treatment), concentrations of the drug in the body can accumulate, resulting in toxicity. Physicians who monitor methadone patients closely during the induction phase of treatment lessen the risk of death or nonfatal overdose for those patients. Individuals in opioid addiction treatment or pain management also are counseled to refrain from taking their methadone in combination with other drugs and/or alcohol, which can lead to a poisoning death. Patients who are properly counseled by physicians who have received adequate training in the pharmacokinetic5 and pharmacodynamic6 properties of methadone are less likely to overdose or misuse the drug.
The total amount of methadone legitimately distributed to businesses has increased, with the greatest percentage change occurring at the practitioner level. Legitimate distribution of methadone to pharmacies, hospitals, and practitioners increased from 2001 through 2006 (the most current data available; see Table 1), according to the Drug Enforcement Administration (DEA).7 This increase indicates that a growing number of practitioners are dispensing methadone to manage pain. Many practitioners began to dispense methadone as a pain reliever following the negative publicity surrounding OxyContin's high potential for addiction and abuse.

Methadone is one of the narcotic analgesics8 most frequently submitted to state and local forensic laboratories; the number of submissions increased overall in all areas of the country from 2001 through 2006. Data from the DEA National Forensic Laboratory Information System (NFLIS)9 indicate that methadone was the third most frequently identified narcotic analgesic submitted to state and local forensic laboratories from 2001 through 2006. The number of methadone submissions increased overall during that time in all regions, although submissions in the Northeast fluctuated each year, while submissions in the Midwest increased overall but decreased by one from 2004 to 2005. (See Figure 2.) According to NFLIS data, methadone was not listed among the 25 most frequently identified drugs in 2000 but progressed in rank from sixteenth in 2001 to tenth in 2006, indicating an increase in diversion and illicit availability.

Theft of methadone during transit from the manufacturers to businesses and theft from businesses and reverse distributors increased the availability of methadone at the midlevel and retail level. The number of reported lost-in-transit thefts involving methadone en route to pharmacies, hospitals, and distributors increased from approximately 28 in 2004 to 39 in 2005 and 68 in 2006. Approximate dosage units10 (du) reported stolen in these lost-in-transit incidents were 18,547 in 2004, 22,201 in 2005, and 67,867 in 2006 (108,615 total du). An additional 9,125 tablet/capsule dosage units were lost in transit to methadone clinics in 2006. The number of reported methadone thefts (burglaries, armed robberies, employee pilferage, and customer theft) from pharmacies, hospitals, and distributors decreased from 2004 (210) through 2006 (138). The number of dosage units stolen in these thefts also decreased during that time; however, the quantity of methadone diverted through theft remained substantial (112,478 du in 2004, 100,390 in 2005, and 71,119 in 2006), according to DEA. An additional 18,536 dosage units of methadone tablet/capsules were diverted through theft from clinics in 2006. Theft from reverse distributors very likely increases availability at the midlevel and retail level; however, the extent to which this type of theft occurs is unknown. Most manufacturers authorize the reverse distributors to destroy the drugs in accordance with the law, and the reverse distributors are required to report to DEA quarterly and document the quantity of drugs returned as well as the disposal of the substances. Some of the methadone sent to reverse distributors very likely is stolen before it is destroyed, particularly in instances where the returned drugs are stored in warehouses before incineration, flushing (where permitted), or another acceptable destruction method is implemented.
Diversion from pain management facilities, hospitals, pharmacies, general practitioners, family and friends and, to a lesser extent, NTPs increased availability primarily at the retail level. Personal use quantities of methadone commonly are diverted through prescription fraud, theft of prescription pads from doctors' offices, theft from pharmacies, and theft from family and friends. Additionally, some patients with legitimate methadone prescriptions sell a portion of their prescribed allotment to friends, family, and strangers. Methadone diversion from NTPs has been a concern for law enforcement and public health officials for decades. That concern heightened in 2001 when SAMHSA implemented new regulations that permitted NTP personnel to dispense take-home doses of methadone to certain well-established patients in advanced courses of treatment. However, the growth in the number of NTPs administering methadone and in the number of individuals receiving treatment has been modest, according to SAMHSA. Conversely, legitimate distribution of methadone to pharmacies, hospitals, and practitioners increased 250 percent from nearly 1.9 million grams in 2001 to over 6.6 million grams in 2006 (the most current data available; see Figure 3), according to DEA.

Retail-level distribution of diverted methadone may be occurring more frequently than law enforcement reporting indicates. A 2005 survey11 of prescription opioid abusers indicates that most obtained their drugs either exclusively from dealers or from dealers and two or more other sources (59 percent of the respondents reported two or more sources for their primary drug). The 2,174 survey respondents--individuals enrolled in federally approved NTPs who indicated that their primary opioid drug of abuse was a prescription opioid--listed the following as their most frequent sources of supply: 86 percent reported dealers, 54 percent reported friends or relatives, 28 percent reported a doctor's prescription, 13 percent reported an emergency room, and 7 percent reported theft. Few respondents reported that they had obtained their primary opioid from the Internet or forged prescriptions (3% each) or in other ways (2%). Enrollees with chronic pain were less likely to report a dealer as a source (82% versus 89%) and were more likely to report a doctor's prescription as a source (31% versus 25%). The responses are similar for sources of supply for specific prescription opioids, including methadone, according to the study. (In this survey, 58 percent of respondents reported lifetime abuse of methadone, and 40 percent reported that they had abused methadone in the 30 days prior to seeking treatment.) It is possible that retail-level methadone distributors are obtaining the drug from criminals involved in bulk theft from tractor-trailers and local courier trucks and from criminals involved in pharmacy burglaries and armed robberies. Other sources of supply for retail-level distributors may be the Internet or polydrug trafficking organizations based in Canada and Mexico, which obtain the drug from corrupt pharmacists and doctors in those countries. Additionally, unscrupulous doctors and pharmacists in the United States most likely divert methadone to retail-level dealers.
Some methadone deaths and nonfatal overdoses are the result of misuse of legitimately prescribed methadone by individuals who may not have been properly counseled by their physicians about the dangers of taking the drug in ways other than those prescribed. Methadone is an effective pain reliever, as are all opioid analgesics when used as prescribed. It is also potentially addictive and is particularly dangerous when taken in combination with other drugs and/or alcohol. Patients who are properly counseled by physicians who have received adequate training in the pharmacokinetic and pharmacodynamic properties of methadone are less likely to overdose or misuse the drug. Physicians who legitimately specialize in pain management receive the extensive training necessary to prescribe opioid-based pain medications and effectively monitor their patients, particularly during the initial stages of treatment. Patients treated at pain management clinics also enter into a contractual agreement with the physician, during which time the dangers of any prescribed medications and the patients' responsibility in taking the medication as prescribed are discussed.
Methadone Prescribing Practices The Food and Drug Administration (FDA) approved the 40-milligram methadone tablet (also known as a "diskette") for use in NTPs, but not for the management of pain. However, physicians can prescribe a drug for other uses (referred to as "off-label"), and some do use the 40-milligram methadone tablet off-label for the management of pain. According to DEA, distribution of 40-milligram methadone tablets to pharmacies is increasing in response to increased prescribing by practitioners. Some medical experts believe that methadone should not be a practitioner's first choice in the treatment of acute pain or management of chronic pain because the drug is more complicated for patients--particularly those who have not been treated with opioids in the past--to use during the initial stages of treatment. Hydrocodone and oxycodone products, when used appropriately, are less complicated pain medications with regard to dosing and side effects. Many physicians, however, do prescribe methadone more often than other opioid medications because of increased negative publicity surrounding the abuse of oxycodone products (primarily OxyContin), increased law enforcement scrutiny of OxyContin prescribing practices, and pressure from insurers to prescribe less expensive medications. General practitioners and pain specialists can limit misuse or diversion of prescribed methadone by requiring frequent patient checkups and prescribing smaller quantities of methadone to patients, lessening the likelihood that they will sell a portion of their prescription to friends, relatives, or strangers or take more than is medically safe. |
Some general practitioners and novice pain management physicians may lack the training necessary to adequately monitor patients to whom they prescribe methadone. Washington State health officials were the first in the nation to issue guidelines to help practitioners better evaluate and monitor opioid medications for their patients. The guidelines and a web site, which were unveiled in March 2007, provide practitioners with the tools necessary to ensure the safety of patients to whom they prescribe opioid medications, including methadone. Dosages are not dictated in the guidelines; however, a 120-milligram limit is suggested if both pain and physical function are not improving in the patient. Moreover, the guidelines recommend that a general practitioner seek a second opinion from a pain management specialist if the patient is not improving and the recommended dosage limit has been met. The guidelines were designed under an educational pilot program; short- and long-term evaluation is needed to determine the success of the pilot program.
Public Health Advisory The FDA issued a public health advisory in November 2006 to provide patients and their caregivers and health care professionals with safety information to prevent serious complications from methadone use. The advisory stated: "Prescribing methadone is complex. Methadone should only be prescribed for patients with moderate to severe pain when their pain is not improved with other non-narcotic pain relievers. Pain relief from a dose of methadone lasts about 4 to 8 hours. However, methadone stays in the body much longer, from 8 to 59 hours after it is taken. As a result, patients may feel the need for more pain relief before methadone is gone from the body. Methadone may build up in the body to a toxic level if it is taken too often, if the amount taken is too high, or if it is taken with certain other medications or supplements." |
The number of individuals calling poison control centers to report adverse reactions or nonfatal overdoses from unintentional misuse of prescription and diverted methadone increased from 2,747 in 2002 to 4,311 in 2005 (the year for which most current data are available), and most of those incidents (1,956 in 2002 and 3,388 in 2005) resulted in visits to healthcare facilities, according to the American Association of Poison Control Centers (AAPCC). (See Figure 4.) It should be noted that AAPCC data sets do not distinguish between methadone used for opioid addiction treatment and methadone prescribed for pain.

Methadone poisoning deaths nationwide increased significantly from 1999 through 2004, and data indicate that the number of deaths in many states continued to increase in 2005 and 2006. Poisoning deaths in which methadone was mentioned increased 390 percent--from 786 in 1999 to 3,849 in 2004 (the latest year for which such data are available); however, the number of deaths involving methadone was far lower than the number of deaths involving other prescription opioids (hydrocodone, hydromorphone, morphine, and oxycodone; see Table 2), according to the National Center for Health Statistics (NCHS). The highest rate of increase for methadone poisoning deaths was among individuals 15 to 24 years of age--the rate in 2004 was 11 times higher than that in 1999. In comparison, among those 35 to 44 and 45 to 54 years of age, the rate of increase in 2004 was seven times higher than the rate in 1999, according to NCHS.

SAMHSA studies indicate that a large number of methadone deaths were reported nationwide prior to the 2001 change in the dispensing regulations. For example, data from the FDA Safety Information and Adverse Event Reporting Program indicate that 1,114 methadone-associated deaths were reported from 1970 through 2002. Methadone deaths often do not involve individuals who had access to methadone dispensed through treatment programs, according to SAMHSA. A 2004 SAMHSA national assessment of methadone poisoning deaths determined that most deaths involved one of three scenarios:
The eight states with the highest numbers of methadone deaths reported to the Centers for Disease Control and Prevention (CDC) in 2002, 2003, and 2004 included Florida, North Carolina, New York, Washington, Texas, California, Virginia, and Kentucky. Also in the top 10 in 2002 were Oregon and Illinois; Oklahoma and West Virginia/Pennsylvania (each had 67 deaths) replaced Oregon and Illinois in 2003, and in 2004 Ohio replaced West Virginia/Pennsylvania in the rankings. The number of reported deaths increased in most states between 2002 and 2005, as shown in Figures 5, 6, and 7. The states with the highest percentage increase in deaths from 1999 through 2004 are shown in Table 3.

The following health department data collected from selected states12 indicate that methadone poisoning deaths increased from 2004 through 2005 or from 2005 through 2006 (in each case, the most current data available):
Pain management physicians and general practitioners will continue to prescribe methadone to patients suffering from acute or chronic pain because it is one of the less costly opioid pain medications, has a longer duration of action than many other prescription opioids, and is effective. However, practitioners will become better educated on the dangers of prescribing methadone, particularly to those patients who are not opioid-tolerant. Poisoning deaths and exposures involving medical use of methadone will very likely begin to decrease over the next few years as more practitioners update their training regarding methadone's pharmacokinetic and pharmacodynamic properties and become better able to counsel their patients about the dangers of taking the drug in ways other than those prescribed.
Public health officials will very likely respond to the increase in methadone diversion and poisoning deaths by establishing prevention programs that specifically target those most at risk of misusing, abusing, becoming addicted to, or overdosing on methadone. Diversion will remain a problem until demand for the drug decreases, which will be accomplished by directing prevention education at teens and young adults who have not begun to misuse or abuse the drug. Moreover, adults who learn the dangers of taking methadone improperly need to educate their children as well, which will help decrease the number of nonfatal and fatal overdoses in the future. Additionally, methadone education aimed at opioid abusers participating in NTPs will help decrease death rates among that population.
Law enforcement targeting of theft of wholesale and midlevel quantities of methadone will decrease the amount of diverted methadone available at the midlevel and retail level. Law enforcement investigations, particularly those involving lost-in-transit theft from tractor-trailers and courier trucks, will identify the manner in which criminals are able to infiltrate the transportation chain from manufacturers to legitimate businesses. Decreasing that specific type of theft will reduce the amount of diverted methadone available at the midlevel and retail level.
Opioid abuse, including heroin abuse, is likely to increase if methadone misuse and abuse are not curbed significantly. As the dangers of becoming addicted to or overdosing on methadone (particularly when the drug is used in combination with other drugs and/or alcohol) become more widely known, those who have become dependent on methadone either during pain management or through recreational use may turn to other prescription opioids, such as hydrocodone or oxycodone, and may eventually switch to heroin. Opioid abusers generally seek out the highest-purity, most inexpensive form of the drug, and in many instances, heroin will be the drug to which prescription opioid abusers turn.
Actual methadone diversion and abuse levels could be more accurately determined if the following intelligence gaps could be resolved:
Surveys usually are the most reliable method used to determine the extent of drug abuse and the drugs most commonly abused over time. Surveys currently used to determine the extent of pharmaceutical abuse, the types of pharmaceuticals abused, and the sources of supply for diverted pharmaceuticals often use the general term "narcotic" and do not specifically mention oxycodone, hydrocodone, methadone, or morphine, which makes it difficult to obtain data on the gaps mentioned above. At least one new survey was initiated in 2005 that will help close some of these intelligence gaps; however, trend analysis will not be possible until several years' worth of data have been obtained.
Many of these intelligence gaps can best be answered by drug abusers, although abusers may not be the most reliable sources of information. Their level of honesty often is based on their own needs and perceptions during law enforcement debriefings, counseling sessions, or treatment interviews. Additionally, survey data are not always based on the respondents' actual experiences because they fear that being honest will result in some negative repercussions.
