Adverse drug reactions don’t just happen on paper — they happen to people. For patients, a single adverse event can trigger physical harm, emotional distress, financial strain, and fear of continuing treatment. What starts as a medical setback can ripple into missed work, reduced quality of life, and loss of trust in care. When reactions are serious, related to treatment, or unexpected, the stakes rise even higher. Understanding how adverse events are identified and escalated isn’t just regulatory—it’s patient protection. Strong pharmacovigilance puts patients first by catching risks early, improving safety decisions, and ensuring treatments are safe.
