The Revised Drug Strategy of the World Health Organization adopted in World Health Assembly Resolution WHA39.27 and revised in Resolution WHA49.14 in May 1996, calls for the preparation of model prescribing information to complement the WHO Model List of Essential Drugs. This will provide source material for adaptation by national authorities - particularly in developing countries - wishing to develop national drug formularies, drug compendia and similar material.

This information is to be regarded as illustrative rather than normative. It is appreciated that it is not possible to develop an information sheet on a specific drug appropriate to circumstances prevailing in each of WHO’s Member States. Also, some countries have already formally adopted texts of their own that have a statutory connotation.

This WHO Model Prescribing Information was written by the Division of Drug Management and Policies with the cooperation of the Action Programme for the Elimination of Leprosy, WHO, Geneva. It describes the WHO currently recommended drugs, doses and dosage regimens for leprosy.
