Older adults with Intellectual Disability have been described as among the most medicated groups in society, with rates of polypharmacy significantly exceeding that of the general population. They are at heightened risk of medication-related harm and have high exposure to high-risk medications, for example, anticholinergic ad sedative medicines. There has been significant controversy internationally relating to the inappropriate use of antipsychotics for challenging behavior, often in the absence of a psychiatric diagnosis. Despite this, the evidence base of the safety of use of medicines in this population is lacking, the provision of healthcare is often suboptimal and this population is often excluded from Randomized Controlled Trials. In this editorial, we describe the unique challenges in ensuring safe and appropriate medicines in this population. We describe tools to date that has been used in this population to measure the burden of medicines that increase the risk of adverse outcomes. We outline current and future developments required to improve the quality and safety of medicines use in this population, for example, longitudinal cohort studies.
