A majority of hypertensive patients will end up suffering uncontrolled hypertension, which is partly due to poor medication adherence. This paper aimed to review a range of interventions that could improve anti-hypertensive medication adherence. Literature search was conducted using PubMed, Scopus, Medline, and Science Direct da- tabases, with publication dates confined to between October 2009 and October 2019. Eventually, only 11 studies were used for this study. It was found that interventions that are based on or include patient education, patient in- terviews, patient reminders, self-management and behavioural modifications have the potential to improve patients’ adherence to anti-hypertensive therapy. Most successful interventions involve patient reminder, self-management and behavioural intervention.
