1 What it all means

2 Question one. Ms. Presley was on methadone under your care years ago. She had been off the program for a few years and restarted back on methadone after a lengthy IV heroin and Oxycontin addiction. She has no features that put her at higher risk of overdose. She was previously on 150mg of methadone. She has now been on 80mg for the past 3 days. She complains of classic opiate withdrawal symptoms 12 hours later. She has ongoing IV use of heroin in the evening time when most of her withdrawals and cravings for opiates start. As 3 days have passed, what do you do?

3 Question one. 1. You increase her to 90mg 2. You increase her to 95mg 3. You hold her dose where it is (80mg)

4 Question one ANSWER Answer 3 Key message After a dose of 80mg has been obtained, you should wait 5-7 days to pass before another increase in methadone. dose increases above 80mg should be 5-10 mg only even if no high risk features

5 Question two. Ms. Presley has reached 120mg and is still complaining of withdrawal 15 hours later. She denies any sedation or side effects from methadone. She denies using he.roin but recently started smoking crack cocaine once to twice a week She wants an increase as she was previously on 150mg and feels uncomfortable with withdrawal late night. What do you do? 1. You increase her cautiously to 130mg after consulting with another specialist 2. You decide to leave her at 120mg as you are not comfortable with high range dosing and offer counselling around her cocaine use 3. You insist on an EKG prior to increasing the dose above 120mg

6 Question two ANSWER Answer either 2 or 3 Key message Cocaine use is a risk factor for QT prolongation. An EKG is required for dosing above 120mg for high risk patients

7 Table 07: Risk Factors for QTc Prolongation in Patients on Methadone Older Age Heart disease cardiomyopathy Myocardial infarction, congestive heart failure, valvular disease, HIV infection Low potassium level On drugs that lower potassium eg. Diuretics Low prothrombin level On medications that inhibit Cytochrome p450 3A4 HIV antivirals e.g. indinavir Antifungals e.g., Fluconazole, ketoconazol Calcium channel blockers e.g., Diltiazem, verapamil Antimicrobials e.g., Norfloxacin Antidepressants e.g., Fluvoxamine Contraceptives e.g., Mifepristone Foods: e.g., grapefruit juice Alcohol use Cocaine use Family or past history of long QT syndrome History of syncope or sudden cardiac death in the family On medications that prolong QTc Cardiac medications amiodarone, sotalol Antipsychotics (chlorpromazine, haloperidol) pimozide, thioridazine Antibiotics e.g., clarithromycin, erythromycin c Anti-nausea drugs e.g., domperidone

8 Question three. Mrs. Jones is on chronic benzodiazepines (Valium 20mg bid recently discontinued by her GP) and is injecting 1 gram of heroin per day. She will be starting methadone today. Her initial urine shows positive opiates and benzodiazepines. She is in obvious opiate withdrawal and has visible track marks. She states she hasn`t had any Valium for the past week, and is worried about having a seizure. She insists that 20 mg will not be enough, as she was previously on methadone last year at a dose of 120mg, and she tells you she has an extra high tolerance as she has been injecting heroin for over 15 years. What dose would you start this patient at?

9 Question three 1. Start on 20 mg with reassurance 2. Start at 25 mg as it is under 30mg, and she has a known high tolerance 3. Start at 30mg given ongoing IVDU heroin use and risks of this. 4. Either 2 or 3

10 Question three ANSWER Answer 1 only Key point. Patients who are on chronic benzodiazepines, or alcohol are high risk for overdose and should be started at 20mg or less regardless of opioid use history

11 Table 03: Patient Factors that Increase Risk of Methadone Toxicity High Risk Patients Recent benzodiazepine use Use of other sedating drugs Alcohol-dependent patients Over 60 years old Respiratory Illnesses Taking drugs that inhibit methadone metabolism Lower opioid tolerance Decompensated hepatic disease Recent discharge from inpatient rehabilitation facility Recent incarceration

30 Question nine ANSWER Answer 4 Key message... The MMT physician shall cancel all take-home doses abruptly in the circumstances listed below. The daily observed dose should be reduced if the MMT physician suspects the patient may not have been taking the full take-home dose. There is reasonably strong evidence that the patient has diverted their methadone dose, or has tampered with their UDS. The patient has missed 3 or more days of methadone (except in unavoidable circumstances such as hospitalization). The patient has become homeless or in unstable housing, and can no longer safely store their methadone. The patient is actively suicidal, cognitively impaired, psychotic, or is otherwise at high risk for misuse of their methadone dose. The patient has recently been released from jail when incarcerated for prolonged periods of greater than 3 months. Once carries are removed, they should be increased 1 every week or more back to 6 carries.

31 Question ten Sheila has been a patient for more than 1 year. She has been stable since starting methadone and is now receiving 6 carries. She was had charges pending from illegal activity prior to starting methadone. She goes to court and ends up in jail for 3 weeks. Her methadone is continued while she is incarcerated.

What do you do with her carries?

32 Question ten. 1. Hold all carries given that she was incarcerated and therefore unstable. Return one every week back to 6 carries. 2. Given charges were from prior to becoming stable on methadone and short incarceration, and given ongoing stability without relapse, reinstate all carries now and continue to monitor as you were prior to incarceration. 3. Decrease to 5 carries and monitor more carefully to ensure stability.

33 ANSWER Answer 2 Key point The MMT physician may reinstate take-home doses immediately for patients who remain clinically stable without problematic drug use, and: 1) had take-home doses cancelled due only to missed doses 2) have been incarcerated for less than 3 months

40 Question twelve Stephen is a new patient and doing well on methadone. He has stable housing, is in a relationship now, and looking for a new job. He has been on the program for more than 2 months now and has a stable dose without any illicit substance use. On September 10 you start 1 carry. You document on the program for more than 2 months and ongoing stability now. You see him on September 17 and he continues to do well. On September 24 he complains that his dose is not quite enough. He is continuing to notice sweats, chills, restlessness, irritability, anxiousness and runny nose for 3-4 hours before his dose is due. You document all of this in your notes and increase his dose 5mg. On October 1 you see him and he is doing well and you start 2 carries (the forth week). You are being assessed and the CPSO methadone assessor has some concerns about this chart. What could they be?

41 Question twelve 1. You did not document discussion about carries, safety of carries, risks of carries to children and diversion. 2. You increased the carries too quickly 3. You continued carries despite the patient needing minor dose adjustment 4. Both 1 and 2 are correct 5. 1,2 and 3 are correct

42 Question twelve ANSWER ANSWER: 4 Key Message. Even if you have information about carries and safety in your treatment agreement, safety and safe storage of carries must be discussed and documented. You can use a carry agreement and document that this was reviewed prior to starting carries. Small dose adjustments do not mean that a patient is not stable Carries should be increase every 4 weeks (having 1 carry for 4 weeks Sept 10, 17, 24 and Oct 1 and then increase to 2 carries on October 8). Many physicians have difficulty with this. Ensure they have had their carry level for 4 weeks and then increase carries.
