Condition(s) targeted: Hepatitis C; Substance Dependence; Methadone

Intervention: Methadone (Drug)

Phase: Phase 3

The rapid scale up of opioid substitution treatment (OST) for drug users mainly achieved through the possibility of prescribing buprenorphine in primary care has been successful in reducing HIV prevalence among drug users but still inadequate for reducing the spread of HCV. To date, methadone in France can only be initialised in drug centres but GPs can prescribe methadone after stabilisation of dosages.

This study was born as an answer to a request from the French Minister of Health that supports the initialisation of methadone in primary care in order to improve coverage by OST (now 70%) in Intravenous drug users.
