Investigation of methadone dosing in Victoria: Factors influencing
dosing levels. Fitzroy, Victoria: Turning Point Alcohol and
Drug Centre
Turning Point Alcohol and Drug Centre has completed a project
which explored methadone dose levels in Victoria. According
to the National Clinical Guidelines, the optimal dose for
methadone should typically exceed 60 mg per day, however in
Victoria the estimated average daily dose is 50 mg. This project,
commissioned by the Victorian Department of Human Services
(DHS), sought to investigate Victoria's methadone dose levels,
determine the factors influencing dose levels, and identify
the barriers to optimal dosing.
Data were collected from a range of sources, including:
dosing information from 17 pharmacies, information on the
amount of methadone syrup supplied to Victoria each year,
and interviews with nine methadone prescribers and 30 methadone
clients. According to pharmacy dose data, the average methadone
dose was 54 mg, which is lower than the recommended level.
The main reasons for low methadone dosing included client
concerns about side effects, client focus on reducing their
methadone dose, and the belief that lower doses are associated
with easier withdrawal and short-term programs.
