What is informed consent for medication? What should my prescriber have told me?

Informed consent for medication is a discussion, not only a signature. A prescriber should typically cover the indication being treated, reasonable options including no medicine, expected benefits, common and serious risks, monitoring, and the right to ask questions. The College of Physicians and Surgeons of Ontario sets out consent-to-treatment principles for physicians practising in Ontario. If the change is persistent, distressing, or affecting daily functioning, bring a brief timeline to the prescribing clinician rather than changing the dose independently.
