Medication errors remain among the most frequent and most preventable causes of avoidable harm in health care, occurring at every stage of the medication use process — prescribing, transcribing, dispensing, administration and monitoring. Because the pharmacist is the only professional whose training spans the whole of this pathway, the profession occupies a uniquely favourable position from which to intercept error before it reaches the patient. This review synthesises the evidence on pharmacist-led interventions for medication error reduction and organises it around the points in the medication use process at which pharmacists act. Prescribing-stage interventions — ward-based clinical pharmacy, participation in physician rounds and prescription review — consistently produce the largest absolute reductions in error, since the prescribing stage generates the greatest share of errors and permits interception before any drug is administered. Medication reconciliation at admission, transfer and discharge addresses the transitions of care at which discrepancies concentrate. Dispensing-stage safeguards, antimicrobial and anticoagulation stewardship, patient counselling and pharmacovigilance participation each contribute further. Technology, including computerised prescriber order entry, clinical decision support, barcode-assisted administration and automated dispensing, amplifies pharmacist effectiveness but introduces its own error modes and cannot substitute for professional judgement. Sustained benefit depends less on any single intervention than on the surrounding conditions: adequate pharmacist-to-bed ratios, a non-punitive reporting culture, interdisciplinary credibility and integration into the clinical team rather than confinement to the dispensary. Barriers relevant to resource-limited settings — staffing shortfalls, restricted access to drug information, hierarchical professional relationships and the absence of formal error reporting systems — are examined alongside practical strategies to address them. The evidence supports a clear conclusion: pharmacists reduce medication errors substantially when positioned within the clinical team, and the principal obstacle is no longer proof of effectiveness but the structural investment required to deploy them.
