Patient concerns regarding antidepressant drug–drug interactions: a retrospective analysis using data from a medicines call centre.

Introduction Antidepressant use has increased over the last two decades, with Australia and New Zealand among the highest antidepressant users in Organisation for Economic Co-operation and Development (OECD) countries. Comorbidity and polypharmacy are common in antidepressant users, increasing the likelihood of interaction-related adverse drug events, which are frequently preventable. Aim We aimed to identify, profile, and analyse potential antidepressant drug-drug interactions in information-seeking antidepressant users.
