Nonprescription drug therapy is tightly woven into the fabric of American health care. Market forces are expected to contribute to significant expansion of nonprescription drug use. Consumers place high value on nonprescription drug therapy; however, self-medicating patients frequently need assistance from a learned intermediary to assure optimal integration of nonprescription drug therapy into the total care regimen. Pharmacist-assisted self-care holds vast potential to serve the public interest, but this expanded practice role will require higher levels of professional practice commitment by American pharmacy. That commitment must be supported by practice-relevant, competency-based, patient-centered college and school of pharmacy curricula and continuing education that assures perpetual intellectual proficiency in nonprescription drug pharmacotherapy. That knowledge and competency must be integrated holistically into the total mix of patient comorbidity and polypharmacy. The pharmacist-assisted self-care business and professional practice model must be further facilitated by state and national pharmacy organizations, chain and independent community pharmacy, pharmacy wholesalers, and others. Consumers await expanded and differentiated pharmacy-based, pharmacist-provided medication therapy management services focused on the safe, appropriate, and effective selection, use, and monitoring of nonprescription drugs therapy.
