GP Program - Medication assisted treatment for opioid dependence

Prescribing medications for opioid dependence

South Australia has approximately 3000 people prescribed methadone liquid or buprenorphine with naloxone in film form (Suboxone®) to assist with the management of their opioid dependence.

Approximately two thirds of these patients are managed by community prescribers - the majority of these are general practitioners (GPs).

Prescribing medications for opioid dependence is not complicated, however, there are some specific issues around the medications themselves, and about caring for people with opioid dependence that need to be considered when prescribing this treatment.

Prescribing buprenorphine with naloxone in film form (Suboxone®) for opioid dependence (non-accredited prescribing)

In South Australia a medical practitioner does NOT need to be accredited to prescribe buprenorphine with naloxone in film form for up to five patients for opioid dependence.

Medical practitioners need to obtain a Section 18A Controlled Substances Act 1984 (SA) authority (PDF 185KB) from the SA Health Drugs of Dependence Unit prior to prescribing a drug of dependence for the treatment of opioid dependence. This authority must be obtained before treatment commences.

The Drugs of Dependence Unit can be contacted on 1300 652 584 Monday to Friday 9.00 am to 5.00 pm.

The following resources provide further information about prescribing this drug.

This document can be used as a checklist of steps to be taken when patients are being initiated into medication assisted treatment with buprenorphine/naloxone (Suboxone®)

Additional clinical resources are provided below.

A medical practitioner must become ACCREDITED if they wish to:

  • treat more than five patients at one time with buprenorphine with naloxone in film form
  • prescribe methadone liquid or buprenorphine as a single agent (Subutex®).

  • Medications for Symptomatic Opiate Withdrawal (SOW) Management (PDF 52KB)
    In many instances, withdrawal may need to be managed with symptomatic medication rather than with buprenorphine. This list outlines what is used currently at DASSA for symptomatic relief of opioid withdrawal. Of course, in most situations buprenorphine-assisted detox is preferable.
  • Prescription Review (PDF 51KB)
    This form is used for recording review consultations with patients established on opioid pharmacotherapy.
  • Maintenance Pharmacotherapy - Stabilisation / Withdrawal (including cows - Clinical Opiate Withdrawal Scale) (PDF 97KB)
    This form is used in the first days of stabilisation and includes a running sheet on one side, together with a COWS assessment tool for each day for recording the patient’s subjective assessment of withdrawal.
  • Methadone — drug to drug interactions (including QTc Prolongation) (DOC 52KB)

    You may wish to include this in your patient’s file, put a copy in your practice policy folder, and/or laminate a copy for your consulting room.
  • Monitoring of patient prescriptions from other doctors (PDF 42KB)

    It is important to be aware of other drugs the patient may be using when prescribing methadone or buprenorphine due to possible drug interactions. Patients may provide information about their other drug use along with Urine Drug Screens (UDS).
    There are systems in place that may provide you with additional sources of information about your patient. Patients may provide more accurate information if they know that you can check the information they give you.

    The systems listed in the attached document above appear to be extensive, however, once the initial paperwork has been completed, accessing the information is relatively straightforward. The GP Program Project Officer has put together packs with all the relevant forms and additional information that you may require. Please contact the GP Program Project Officer for a copy of this pack on (08) 7425 5045 or email: dassa.gpprogram@health.sa.gov.au.
