An EKG is required for dosing above 120mg for high risk patients Table 07: Risk Factors for QTc Prolongation in Patients on Methadone Older Age Heart disease Myocardial infarction, congestive heart failure, valvular disease, cardiomyopathy 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, c erythromycin Anti-nausea drugs e.g., domperidone Question three….

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. Question ten… Sheila has been a patient for more than 1 year.

Decrease to 5 carries and monitor more carefully to ensure stability. 1. 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 Question eleven… Sandra is a new patient who started on the program 2 weeks ago. She has stabilized on her dose and it is now lasting 24 hours without any withdrawals or need for opioid use. She is not using any other substances.

On further questioning, she tells you that she needs to work. She found a job however will be working 1 hour out of town. She will be picked up by a co-worker at 0700 and may not get home until after 7:00pm. The community pharmacy is only open from 8:00am – 6:00pm and there are no other pharmacies in the community that open earlier or later. She tells you that she needs to take this job and cannot be on methadone. Can you expedite her carries? Question eleven… Not yet.

The first accelerated take-home dose may be given after one month, with one additional weekly dose every 2-4 weeks. 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? Question twelve… 1. 2. 3. 4. 5. You did not document discussion about carries, safety of carries, risks of carries to children and diversion. You increased the carries too quickly You continued carries despite the patient needing minor dose adjustment Both 1 and 2 are correct 1,2 and 3 are correct 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. Question thirteen… Ms. Presley had been stable at 80mg receiving 6 carries. She missed 4 days of methadone She used valium once 3 days ago and used daily IV heroin She is in obvious withdrawal when you see her. What do you do with her dose? 1. You start her at 30mg and increase by 10mg per day back up to 50mg and then reassess her at 50mg 2. You restart her at either 20mg or 30mg and reassess her in 3 days to assess clinical stability and counsel patient on dangers of benzodiazepines. 3. You drop the dose to 60mg and hold her on this dose for one week. Question thirteen ANSWER ANSWER: 2 You should restart at 20mg or 30mg. and reassess the patient in 3-7 days after 4 missed days After 3 missed days, the dose may be decreased to 50 percent of the previous dose. 10mg daily increases should only be done after 3 missed days. The patient should be reassessed after 3 days if you are increasing the dose daily by 10mg daily
