            “The nonmedical use or abuse of prescription drugs is a
          serious and growing public health problem in this country.
         The elderly are among those most vulnerable to prescription
            drug abuse or misuse because they are prescribed more
          medications than their younger counterparts. Most people
            take prescription medications responsibly; however, an
           estimated 48 million people (ages 12 and older) have used
         prescription drugs for nonmedical reasons in their lifetimes.
              This represents approximately 20 percent of the U.S.
                                 population.”

      Prescription drug misuse: A concerning trend
         While most people take prescription medications
         responsibly for the reasons in which the medications
         were prescribed, there has been an increasing trend
         in non-medical use of pharmaceuticals.

         Video and images of prescription drugs misuse and
         abuse are increasing as the media reporting on the
         popularizing of pharmaceuticals intensifies.




       Increase in Controlled Substance Abuse
       (1992-2003)




       Scope of the Problem
         6.4 million (2.6%) of people aged 12 or older
         used prescription psychotherapeutic drugs for
         nonmedical reasons in the past month
           4.7 million used pain relievers
           1.8 million used tranquilizer
           1.1 million used stimulants
         Nonmedical use of pain relievers and marijuana
         account for the largest number of first-time
         abuse

       Prescription Drug Abuse in Appalachia
           Admission rates for the primary abuse of opiates
           and synthetic are higher in Appalachia than in the
           rest of the nation.
           Rates are rising across the nation and in
           Appalachia, the rate of increase in Appalachia is
           greater; particularly in Appalachian coal mining
           areas.

         Trends in Use
              People use potentially addicting prescription
              or OTC medications in the following manner:
                For legitimate medical treatment
                As a substitute when drug of choice (DOC) is not
                available
                As a booster for a more intense high
                As an alternative when DOC has been eliminated
                from use by drug testing
                As an alternative addictive drug prescribed by
                physicians

         Defining Abuse
              Appropriate use
                Use of controlled substance as prescribed for defined
                condition with no signs of misuse or abuse.
              Misuse/inappropriate use
                Use of controlled substance for reason other than that
                for which it was prescribed or in dosage different than
                that prescribed
              Abuse
                Use of controlled substance outside normally
                accepted standards of use, resulting in disability
                and/or dysfunction.




         Dependence and Tolerance
              Physical dependence does not equal abuse
              Dependence: abrupt cessation of intake of
              a substance leads to characteristic
              withdrawal symptoms
              Tolerance: state in which escalating doses
              must be ingested to attain the same effect

      Dependence, Addiction, and Pseudo-addiction

               Dependence
               Addiction
               Pseudo-addiction
                 Person engages in drug-seeking behavior
                 simply to obtain therapeutic and effective
                 dosage of medication




           Pharmacologic Properties of Medications
           Likely to be Abused

               Rapid onset of action
               High degree of potency or intensity
               Brief duration of action
               High purity and water solubility
               High volatility

        Stimulants
             Misuse most frequently involves immediate-
             release methylphenidate and dextroamphetamine
             Past year use is more prevalent among person
             aged 25 years or younger
             Peak use in mid-1990s, annual prevalence of
             amphetamine use has fallen in all age categories
             since that time
             2.8% percent of all 12th graders reported they
             had used Adderall®.
             Amphetamines rank fourth among 12th graders

        Benzodiazepines
             Rarely sole or preferred drug of abuse
             High doses used to enhance the euphoria
             effects of opioids; boost methadone or

          Prescription Drug Abuse in the Elderly
               Overall prevalence of prescription abuse is difficult to
               estimate
               11% of older women misuse/abuse (Simona-Wastila, 2006)
               As baby boom cohort ages, extent of alcohol and
               medication misuse is predicted to significantly increase
               Factors associated with drug abuse in older adults

       Preventing prescription drug abuse/misuse

        Prescription drug abuse prevention is
        a is an important part of patient care.


        Nearly 70 percent of Americans (191
        million people) - visit a health care
        provider, such as a primary care
        physician, at least once every 2 years.


        Accurate screening and increases in
        medication should be careful
        monitored by physicians as well as the
        patient receiving the medication.
                                                           (National Institute on Drug Abuse [NIDA], 2001)

           Refuse diagnostic workup or consultation
           Sophisticated knowledge of drugs
           “You are the only one who can help me”
           “Lost” prescriptions




       Patterns of Use Indicating Risk
           Escalating use of a substance without
           consultation with a physician
           Use of a substance for effects independent
           of a defined medical condition
           Continued use of a substance despite
           negative consequences
           Preoccupation with obtaining the
           substance

       Patterns of Use Indicating Risk
          Unauthorized emergency department
          visits
          Resisting changes in therapy or use of
          alternative therapies
          Having been discharged from another
          clinician’s practice for noncompliance

      Prescription forgery     Injecting oral formulations
      Overdose                 Altering route of administration




       Common Scams
          Spilled the bottle…
          Lost the prescription…
          It is the only thing that works…
          Stolen from my home…
          But you filled it before…
          Prescription stealing or altering…
          Washed the prescription in the laundry…




       “We have met the enemy…”
        Editorial by Dr. Ron Pawl, published in May 2008 in
        Surgical Neurology
        Discusses the dramatic rising prescription rates of
        opioids for non-disease based pain
        Emphasizes the lack of evidence supporting use of
        narcotics to treat psychological-based chronic pain
        “…part of our medical leadership in pain medicine, some
        of the practitioners of pain medicine and the
        pharmaceutical industry all have contributed to the
        increased use of narcotic medications and
        unprecedented rise in narcotic drug abuse. We have
        met the enemy and they are ourselves.”

           If handwriting prescriptions, keep blanks in secure location
           Use watermark paper or prescription pads
        Choose long-acting opioids and opioids of lesser street
        value

        No refills
        Use letters and numbers to document quantity and
        strength
        Allow only the patient to pick-up prescriptions




      Office Practice Standards
          Office-wide controlled substance policy
          Office visit documentation templates

       Safe Prescribing Practices
         Ensure that there is clear clinical indication for
         the drug
         Define the therapeutic end point
         Do not prescribe controlled substances on the
         first visit
         Obtain all medical records and review before
         prescribing any controlled substance
         State your refill policy up front

         to be seen.
         Trust your instincts! Take precautions when you
         are suspicious.
         Never prescribe drugs simply to get rid of a drug-
         seeking patient.
         Ensure that all prescribing and dispensing of
         controlled substances are conducted within the
         scope of practice and part of a valid practitioner-
         patient relationship.




       Characteristics of Fraudulent Prescriptions

         Prescription looks “too good”
         Quantities, directions or dosages differ
         from the usual medical usage

         Prescription appears to be photocopied
         Directions written in full without
         abbreviations
         Prescriptions written in different color inks
         or in different handwriting

VRHA/VFC Annual Conference 2009




       Types of Fraudulent Prescriptions
         Legitimate prescription pads stolen from
         physician office and written for fictitious
         patients.
         Alteration of the physician’s prescription.
         Change call-back number on prescription
         Computers used to create prescriptions
         from nonexistent prescribers or to copy
         legitimate prescriptions.




       Types of Fraudulent Prescriptions:
       ? Legitimate Use
         Prescriber writes significantly more prescriptions
         (or larger quantities) compared with other
         prescribers in the area.
         Patient appears to be returning too frequently.
         Prescription written for antagonistic drugs
         (uppers and downers) at the same time.
         Prescriptions written in the names of other
         people.
         A number of people appear simultaneously, or
         within a short time, all bearing similar
         prescriptions from the same physician.




       Prevention Techniques
         Know the prescriber and his/her signature;
         Know the prescriber’s DEA registration
         number;
         Know the patient, and;
         Check the date on the prescription order.
         With any question: CALL THE PRESCRIBER!
         Request proper identification.

VRHA/VFC Annual Conference 2009




       Prevention Techniques
         If you believe you have a forged, altered
         or counterfeit prescription --- don’t
         dispense it!
         If you have discovered a pattern of
         prescription abuses, contact the State
         Board of Pharmacy or your local DEA
         office.




       Disposal of Medications
         Patients may have
         hundreds of tablets on
         hand
         Take unused, unneeded
         or expired drugs out of
         their original containers
         and throw in trash, but
         first….
         Mix with coffee grounds
         or kitty litter and put in
         impermeable cans or
         bags will ensure the
         drugs are not diverted

       Case One: In the Clinic
       A 46 YO female is seen in clinic for
       the first time for evaluation of
       chronic migraine headaches. She
       states she has just moved to the
       area and she does not provide any
       old medical records. While getting
       her history, you discover she has
       a long history of generalized
       anxiety and depression. She
       reports adverse effects to valproic
       acid, codeine, propoxyphene,
       tramadol, and sumitriptan. She
       states that a neurologist saw her
       years ago but that “he did not help
       her at all.” After completing your
       physical exam, the patient
       requests prescriptions for a
       month’s supply of Lortab 10/500
       mg tablets QID and diazepam 5
       mg TID because “those are the
       only things that work.”




       Case One: In the Clinic
          Discuss red flags that alert you to the
          possibility of prescription drug abuse.
          Describe strategies you could employ to

       Case Two: In the Pharmacy
                                              A disheveled appearing man
                                              approaches the pharmacy
                                              counter ten minutes before
                                              closing time and presents a
                                              prescription to the technician.
                                              He is speaking in a loud voice
                                              and demands immediate
                                              attention. The prescription is
                                              from a physician in a town
                                              approximately 45 minutes
                                              away. The prescription is
                                              written for Vicodin, 1 tab po
                                              Q6h prn pain #30 with 4 refills.
                                              It is dated one month ago. He
                                              tells the technician that he
                                              must have the brand name
                                              Vicodin and that he does not
                                              “do well” with the generic. He
                                              states he has no insurance
                                              and then he proceeds to pace
                                              in front of the pharmacy.

VRHA/VFC Annual Conference 2009




       Case Two: In the Pharmacy
         What are some red flags that alert you to
         possible diversion?
         How would you handle this situation?
         What are precautions you should use on a
         regular basis in the pharmacy?




       Conclusion
         Statistics show that prescription drug abuse
         is escalating, especially in Appalachia, with
         increasing ED visits and unintentional
         deaths due to prescription controlled
         substances.
         Several patient and physician factors
         increase risk for prescription drug abuse.
         Recognition of these factors and
         implementation of prevention strategies can
         allow physicians to prescribe controlled
         substances in a safe, effective manner and
         pharmacists to limit diversion in the
         pharmacy.




                                  QUESTIONS?

Prescription and Over-the Counter Drug Misuse and Abuse

  • 1. VRHA/VFC Annual Conference 2009 Prescription and Over-the-Counter Drug Misuse and Abuse Risk Factors, Red Flags, and Prevention Strategies Sarah T. Melton, PharmD,BCPP,CGP 2009 VRHA/VAFC Joint Meeting The Homestead Resort November 17, 2009 “The nonmedical use or abuse of prescription drugs is a serious and growing public health problem in this country. The elderly are among those most vulnerable to prescription drug abuse or misuse because they are prescribed more medications than their younger counterparts. Most people take prescription medications responsibly; however, an estimated 48 million people (ages 12 and older) have used prescription drugs for nonmedical reasons in their lifetimes. This represents approximately 20 percent of the U.S. population.” Nora Volkow, MD. Director, National Institute on Drug Abuse 2 Objectives At the completion of this presentation, the participant will be able to: 1. Examine epidemiologic factors associated with prescription and over-the-counter drug misuse and abuse in Virginia and Central Appalachia. 2. Discuss commonly abused prescription and over-the- counter drugs. 3. Compare and contrast safe patient and prescriber factors that can increase the risk of prescription drug abuse and describe prescribing practices that can limit abuse. 4. Explain the strengths and limitations of prescription- drug monitoring programs. Sarah T. Melton, PharmD,BCPP,CGP 1
  • 2. VRHA/VFC Annual Conference 2009 Prescription drug misuse: A concerning trend While most people take prescription medications responsibly for the reasons in which the medications were prescribed, there has been an increasing trend in non-medical use of pharmaceuticals. Video and images of prescription drugs misuse and abuse are increasing as the media reporting on the popularizing of pharmaceuticals intensifies. Increase in Controlled Substance Abuse (1992-2003) Scope of the Problem 6.4 million (2.6%) of people aged 12 or older used prescription psychotherapeutic drugs for nonmedical reasons in the past month 4.7 million used pain relievers 1.8 million used tranquilizer 1.1 million used stimulants Nonmedical use of pain relievers and marijuana account for the largest number of first-time abuse Sarah T. Melton, PharmD,BCPP,CGP 2

  • 6. VRHA/VFC Annual Conference 2009 Trends in Use People use potentially addicting prescription or OTC medications in the following manner: For legitimate medical treatment As a substitute when drug of choice (DOC) is not available As a booster for a more intense high As an alternative when DOC has been eliminated from use by drug testing As an alternative addictive drug prescribed by physicians Lessenger JE, Feinberg SD.

Melton, PharmD,BCPP,CGP 6

  • 17. VRHA/VFC Annual Conference 2009 Assessing Prescription Drug Abuse: Four Simple Questions Have you ever felt the need to Cut down on your use of prescription drugs? Have you ever felt Annoyed by remarks your friends or loved ones made about your use of prescription drugs? Have you ever felt Guilty of remorseful about your use of prescription drugs? Have you Ever used prescription drugs as a way to “get going” or to “calm down?” Adapted from Ewing, JA. “Detecting Alcoholism: The CAGE Questionnaire.” JAMA 252(14):1905-1907, 1884. Questionnaire.” 252(14):1905- Red Flags for Drug-Seeking Behavior More concerned about the drug than the problem Report multiple medication sensitivities Say they cannot take generic drugs Refuse diagnostic workup or consultation Sophisticated knowledge of drugs “You are the only one who can help me” “Lost” prescriptions Patterns of Use Indicating Risk Escalating use of a substance without consultation with a physician Use of a substance for effects independent of a defined medical condition Continued use of a substance despite negative consequences Preoccupation with obtaining the substance Using opioids to relieve anxiety Abnormal results from a urine drug screen Sarah T.

VRHA/VFC Annual Conference 2009 Patterns of Use Indicating Risk Unauthorized emergency department visits Resisting changes in therapy or use of alternative therapies Having been discharged from another clinician’s practice for noncompliance Prescription forgery Injecting oral formulations Overdose Altering route of administration Common Scams Spilled the bottle… Lost the prescription… It is the only thing that works… Stolen from my home… But you filled it before… Prescription stealing or altering… Washed the prescription in the laundry… “We have met the enemy…” Editorial by Dr. Ron Pawl, published in May 2008 in Surgical Neurology Discusses the dramatic rising prescription rates of opioids for non-disease based pain Emphasizes the lack of evidence supporting use of narcotics to treat psychological-based chronic pain “…part of our medical leadership in pain medicine, some of the practitioners of pain medicine and the pharmaceutical industry all have contributed to the increased use of narcotic medications and unprecedented rise in narcotic drug abuse. We have met the enemy and they are ourselves.” Sarah T. Melton, PharmD,BCPP,CGP 18
  • 19. VRHA/VFC Annual Conference 2009 4 D’s and Other Physician/Pharmacist Factors Dated Duped Dishonest Disabled “Medication mania” “Hypertrophied enabling” “Confrontation phobia” Strategies to Prevent Prescription Drug Abuse Screen for alcohol and drug abuse before prescribing controlled substances Be knowledgeable about controlled substances Be familiar with anxiety, depression, and pain syndromes Document all prescription drugs in medical record Adopt safe prescribing practices Strategies to Prevent Prescription Drug Abuse Use controlled-substance contracts Learn “antiscam” techniques Just say no Turn the tables Collaboration between pharmacists - prescribers Clarify cross-coverage policies Sarah T. Melton, PharmD,BCPP,CGP 19
  • 20. VRHA/VFC Annual Conference 2009 Safe Prescribing Practices Use EMR and fax/electronically send prescriptions If handwriting prescriptions, keep blanks in secure location Use watermark paper or prescription pads Choose long-acting opioids and opioids of lesser street value Limit quantity to no more than 30-day supply No refills Use letters and numbers to document quantity and strength Allow only the patient to pick-up prescriptions Office Practice Standards Office-wide controlled substance policy Office visit documentation templates Opioid risk tools Controlled Substance Agreement Monitoring tools Office visits for periodic reassessment Prescription drug monitoring program data Pharmacy records Urine drug screens Pill counts Safe Prescribing Practices Perform a thorough physical examination and document the results Document the questions asked of the patient and his or her responses Request identification and social security number. Photocopy these documents and include them in the patient’s record Confirm a telephone number at which the patient can be contacted During each visit, confirm the patient’s current address Sarah T. Melton, PharmD,BCPP,CGP 20
  • 21. VRHA/VFC Annual Conference 2009 Safe Prescribing Practices Ensure that there is clear clinical indication for the drug Define the therapeutic end point Do not prescribe controlled substances on the first visit Obtain all medical records and review before prescribing any controlled substance State your refill policy up front Avoid prescribing multiple substances Avoid giving multiple refills without office visits Train staff to respond to suspicious phone calls Safe Prescribing Practices Never telephone prescriptions for an unfamiliar patient; insist the patient make an appointment to be seen. Trust your instincts! Take precautions when you are suspicious. Never prescribe drugs simply to get rid of a drug- seeking patient. Ensure that all prescribing and dispensing of controlled substances are conducted within the scope of practice and part of a valid practitioner- patient relationship. Characteristics of Fraudulent Prescriptions Prescription looks “too good” Quantities, directions or dosages differ from the usual medical usage Appears to be “textbook” prescriptions Prescription appears to be photocopied Directions written in full without abbreviations Prescriptions written in different color inks or in different handwriting Sarah T. Melton, PharmD,BCPP,CGP 21
  • 22. VRHA/VFC Annual Conference 2009 Types of Fraudulent Prescriptions Legitimate prescription pads stolen from physician office and written for fictitious patients. Alteration of the physician’s prescription. Change call-back number on prescription Computers used to create prescriptions from nonexistent prescribers or to copy legitimate prescriptions. Types of Fraudulent Prescriptions: ? Legitimate Use Prescriber writes significantly more prescriptions (or larger quantities) compared with other prescribers in the area. Patient appears to be returning too frequently. Prescription written for antagonistic drugs (uppers and downers) at the same time. Prescriptions written in the names of other people. A number of people appear simultaneously, or within a short time, all bearing similar prescriptions from the same physician. Prevention Techniques Know the prescriber and his/her signature; Know the prescriber’s DEA registration number; Know the patient, and; Check the date on the prescription order. With any question: CALL THE PRESCRIBER! Request proper identification. Sarah T. Melton, PharmD,BCPP,CGP 22
  • 23. VRHA/VFC Annual Conference 2009 Prevention Techniques If you believe you have a forged, altered or counterfeit prescription --- don’t dispense it! If you have discovered a pattern of prescription abuses, contact the State Board of Pharmacy or your local DEA office. Disposal of Medications Patients may have hundreds of tablets on hand Take unused, unneeded or expired drugs out of their original containers and throw in trash, but first…. Mix with coffee grounds or kitty litter and put in impermeable cans or bags will ensure the drugs are not diverted Prescription Monitoring Programs (PMPs) Education and Information Public Health Initiatives Intervention and prevention Investigation and law enforcement Protection and confidentiality Mission: To promote the appropriate use of controlled substances for legitimate medical purposes while deterring the misuse, abuse, and diversion of controlled substances. Sarah T. Melton, PharmD,BCPP,CGP 23
  • 24. VRHA/VFC Annual Conference 2009 Prescription Monitoring Programs Prescription Monitoring Programs Electronic data base of controlled substances dispensed in pharmacies Used to track individual patients Allows healthcare providers to feel more comfortable prescribing and dispensing controlled substances Better able to identify patients at risk for abuse Intervene in problematic cases to minimize risk Katz N, Housel B, Fernandez KC, et al. Update on prescription monitoring in clinical practice: a survey study of prescription monitoring program administrators. Pain Med 2008;9(5): 587-594.

  • 25. VRHA/VFC Annual Conference 2009 Case One: In the Clinic A 46 YO female is seen in clinic for the first time for evaluation of chronic migraine headaches. She states she has just moved to the area and she does not provide any old medical records. While getting her history, you discover she has a long history of generalized anxiety and depression. She reports adverse effects to valproic acid, codeine, propoxyphene, tramadol, and sumitriptan. She states that a neurologist saw her years ago but that “he did not help her at all.” After completing your physical exam, the patient requests prescriptions for a month’s supply of Lortab 10/500 mg tablets QID and diazepam 5 mg TID because “those are the only things that work.” Case One: In the Clinic Discuss red flags that alert you to the possibility of prescription drug abuse. Describe strategies you could employ to prevent prescription drug abuse. Case Two: In the Pharmacy A disheveled appearing man approaches the pharmacy counter ten minutes before closing time and presents a prescription to the technician. He is speaking in a loud voice and demands immediate attention. The prescription is from a physician in a town approximately 45 minutes away. The prescription is written for Vicodin, 1 tab po Q6h prn pain #30 with 4 refills. It is dated one month ago. He tells the technician that he must have the brand name Vicodin and that he does not “do well” with the generic. He states he has no insurance and then he proceeds to pace in front of the pharmacy.

  • 26. VRHA/VFC Annual Conference 2009 Case Two: In the Pharmacy What are some red flags that alert you to possible diversion? How would you handle this situation? What are precautions you should use on a regular basis in the pharmacy? Conclusion Statistics show that prescription drug abuse is escalating, especially in Appalachia, with increasing ED visits and unintentional deaths due to prescription controlled substances. Several patient and physician factors increase risk for prescription drug abuse. Recognition of these factors and implementation of prevention strategies can allow physicians to prescribe controlled substances in a safe, effective manner and pharmacists to limit diversion in the pharmacy.
