These guidelines were developed by general practitioners for general practitioners involved in treating drug dependent patients. They aim to facilitate practitioners in providing safe and effective care for drug dependent patients. Recommendations are evidence based and consistent with those in the European Methadone Guidelines and the UK based 'Drug Misuse and Dependence - Guidelines on Clinical Management'. Current practice in the Irish context was also reflected by representation from GP specialists and the psychiatrists specialising in substance abuse.

The guidelines are intended for use as an aid to Level 1 and Level 2 practitioners managing patients in the primary care setting. General pratitioners working in Health Board treatment services may also find them useful.
