The purpose of this research was to describe mental health service users' access to and satisfaction with health care professionals, including nurses, as related to users' antipsychotic medication concerns. Eighty-one service users were interviewed using a questionnaire. Participants stated that case managers were the most accessible, while psychiatrists were the least accessible. It was perceived that most professionals, apart from general practitioners, had adequate knowledge of medications. Most participants were satisfied with the way health care professionals dealt with the service users' concerns about medications, but almost 16% were dissatisfied with general practitioners. The findings emphasize that access to and satisfaction with health care professionals is an important factor in medication adherence.
