§ Paul FlynnTo ask the Secretary of State for Health what is the range of daily dosages in milligrams of methadone normally recommended for use in drug control treatments. [19712]
§ Ms BlearsThe guidance from the Department on this issue, detailed in "Drug misuse and dependence—guidelines on clinical management" (1989) makes clear that the actual dose given for an individual patient must be assessed and determined by the prescribing doctor.
The clinical guidelines recommend that depending on the individuals tolerance levels the range for the initial dose should be between 10mg and 40mg.
If a follow-up dose is required it should not exceed 30mg. However, a supplementary dose should only be considered where there is evidence of persistent opioid withdrawal. These cases need to be assessed by an experienced medical practitioner.
As far as the subsequent stabilisation period is concerned any increases in dosage should not exceed 10mg per week up to a final total of between 60 and 120mg.
