Medication adherence is critical for therapeutic success and public health. B. Pharm students must understand causes of nonadherence — including patient-related factors (forgetfulness, low health literacy, beliefs), therapy-related factors (complex regimens, adverse effects), socioeconomic issues (cost, access), and system barriers (poor counseling, fragmented care). Pharmacists play a central role in assessing adherence, performing medication reconciliation, providing patient counseling, simplifying regimens, initiating adherence packaging and reminders, and coordinating with clinicians. Practical skills such as motivational interviewing, adherence assessment tools (MPR, PDC, Morisky scale), and telepharmacy enhance outcomes. This topic links pharmacotherapy, communication, and clinical judgment essential for improving medication adherence and patient outcomes. Now let’s test your knowledge with 30 MCQs on this topic.
