The aim of this chapter is to describe the development and evaluation of an online multilingual information resource focused on medication management, targeting people living with dementia and their family caregivers. Maintaining effective medication management is important to allow ongoing quality of life within the community setting and avoiding medication-related preventable hospitalisations for the person living with dementia. Family caregivers are likely to assume the role of medication management on behalf of the person in their care as dementia progresses. Little training or information is available to family caregivers to assist them with this role. A pilot online information resource was developed and evaluated. Responding to the evaluation, this resource was improved, and a more extensive evaluation process was undertaken. The development and evaluation process are outlined with a view to guiding the development of similar resources, especially those targeting linguistically diverse family caregivers and those with dementia. This is especially important given that many older adults will migrate during their lifetime, often to a country where they are not familiar with the language or health services. Extra support is needed to assist older immigrants who are themselves at risk or are caring for someone with dementia.
